Canon lens 入门选择(v1.1)
From MITBBS>Phtogear

标 题: Canon DSLR入门(v1.1)

一。概述
二。佳能镜头概览
三。新手的选择
四。资料区
一。概述
先说说为啥要选择佳能的DSLR。我觉得最重要的理由是你所选择的不仅仅是一个机身,或者一两个镜头,而是一个系统。就目前来看,佳能的机身和镜头(包括副厂),从低到高,选择是最多的,种类齐全,能满足一个摄影爱好者各方面的需要。价格也是各个档次都有,虽然说一分价钱一分货,佳能最好的L系列镜头价格都相对较高,但是也有很多物美价廉的选择。你完全可以用相对廉价的镜头入门,以后再根据自己的喜好调整手中的镜头。而且佳能的产能很强,基本不用担心有钱买不到货的情况。
对于新手而言,佳能DSLR的机身比较合适的是xxxD, 或者xxD系列,现在是400D (Digital Rebel XTi)和30D。前一代是350D(Digital Rebel XT)和20D。本着电子产品买新不买旧的原则,一般推荐买全新的。400D现在的市场价是700多,而30D在1100以上,马上开始的Double Rebate中, 30D有200的Rebate, 价格可降到1000以下,但是400D在市场的压力下也极有可能降价。
如果你对摄影的兴趣很浓厚,而且资金宽裕,那么可以考虑30D,要不然400D也是很好的选择,毕竟DSLR换代速度很快,一个相机不会再像以前那样用上五年十年。
本文的第二部分将是一个佳能镜头的概览。在看下去之前,如果你是摄影的菜鸟,我建议先好好补一补基础知识,比如光圈,快门,ISO之类的,这样会对和镜头相关的问题心里有数,比如大光圈的优势在那里,景深和光圈啥关系,IS是啥,啥是L头,这样挑镜头的时候才好取舍。
二。佳能镜头概览
这是一个概览,而不是详细的评测,要找更具体的资料可看本文的第四部分。可能有人觉得这个列表看的头晕眼花,但是我觉得作为一个系统,那么多可能的选择,这样的列表更适合,即使你现在就打算进一个镜头,对整个系统有个大概的了解也是好的。而且我觉得对摄影感兴趣的话,应当按图索骥,花点时间找些感兴趣的镜头的详细资料来看看,有助你的选择。
现在400D和30D都是APS-C size的sensor,所有焦段要乘1.6,另外Canon是最有可能推出相对廉价的的全幅DSLR的厂家,所以镜头是否兼容全幅(Full frame, FF)也是要考虑的因素。
很多廉价的头被称为狗头,但是狗头不意味着不能用。一方面,缩小光圈之后,很多狗头的成像质量会大大提高,另一方面,很多狗头边缘锐度的丧失在APS-C的DSLR上不再那么明显。如果你手头紧,进廉价头一样可以很好的入门。
(万分感谢tyning和blueice的补充修订)
为了方便表示,我们视购买力把镜头价格分成如下几类:
低,$400以下
中,$400-800
高,$800-1200
极高, $1200以上
注意,上面的价格均是rebate之前的价格,以buydig.com等廉价白店为参考,新品。旧货有deal的额外注出。
a. 超广:
Canon 10-22 f/3.5-4.5 APS-C only, 价格中
Tokina 12-24 f/4 俗称黑卡,18以上可用于FF, 但没优化,价格中
(但超过400不多)
Sigma 12-24 f/4.5-5.6 价格中,可用于全幅
一般来说超广镜头现在都不便宜,而且新手不太好驾驭,所以新入门的建议先观望一下。Sigma虽然画质有些不足,但是全焦段兼容全幅还是值得一提的。
b. 广,中广 (I):
Tamron 17-50 f/2.8 APS-C only (A16) 价格中,但是超过400不多
Canon 17-55 f/2.8 IS APS-C only,价格高
Tamron 17-35 f/2.8-4 (A05),价格低,二手更值
Canon 17-40 f/4L, 价格中
Canon 16-35 f/2.8L, 价格高
这个焦段因为乘1.6后变成最常用的28-80左右,对新入门的而言是应当优先配置的。这个类别里,前两个是APS-C only,A16是预算不足时的最好选择。后三个兼容全副,17-40最为一个相对便宜的L头,做工和画质都没得说,非常的popular。A05除了对焦速度和做工,画质不比最popular的1740差。现在新的价格300不到,可惜到处缺货。而且这个镜头Keh.com和各二手论坛有大量二手转让,一般成色都较新,keh能220左右拿下。实在是非常超值。如果你要大量在光线不足的时候用这个焦段,考虑17-55。16-35除了大光圈,画质和1740比没有质的提高。
我个人的推荐是17-40或者两个tamron之一。
c. 广,中广 (II):
Tamron 28-75 f/2.8 (又称A09),价格低,超值
Canon 24-70 f/2.8L,价格高
Canon 24-105 f/4L IS,价格高
把这几个镜头和前面的分开列,主要是因为这三个头的焦段在FF上更合适些, 在APS-C上有些不够广,但是依然是很好的选择。A09算是这些年Tamron风头最劲的一个头,因为比原厂头便宜一半,质量更轻,而画质只是稍逊而已。如果不介意经常携带两个镜头的话,建议与Canon 17-40L或者Tamron 17-35/2.8-4配对。这样你在17-75这个最常用的焦段 将能够获得素质极高的大光圈组合。这个头无论人像,还是风景,都有很多佳作,在本版C,N各家的持有量也相当大。24-105L是佳能新出的头,虽然光圈最大只有f/4,但是焦段覆盖更广,画质不比24-70差,还带防抖,现在比24-70更受欢迎。
如果你想搞个佳能的胶片机玩玩,或者希望一个变焦覆盖40到80这段,我的推荐是A09。
另外可供选择的不错的镜头有
Sigma 17-70/2.8-4,素质尚可,比前面的三个略差,但是足够用,一个镜头涵盖两个镜头的焦段。价格低。不过Sigma镜头一向不保值,买新的恐怕贬值很快。
Canon 28-135/3.5-4.5 IS USM,第一代IS镜头,画质不错,做工较狗。以前是穷人的最爱,不过自从Tamron的28-75出世了以后,这个镜头不那么受追捧了。价格中,不过刚过400。
Canon 24-85 f/3.5-4.5 胶片时代廉价一镜走天涯的标配, 价格低
Canon 28-105 f/3.5-4.5 据一个对比,在APS-C的DSLR上和24-105L看不出大的区别。价格低
d. 中长:
这里开始就进入Canon的强项了,所以要有钱尽管往上砸,没钱么,也有不错的选择。
低价选择:
Canon 75-300 f/4-5.6 USM III,做工,画质都一般,AF慢,唯一的优点就是价格比较便宜。价格低
Sigma 75-300 f/4-5.6 DG Macro APO,Sigma这个镜头有N款,注意要选择带APO的这个,成像尚可,比上面那个Canon得好。做工,AF速度也慢,不过价钱不错。价格低。
Canon 100-300 f/4.5-5.6 USM,做工,画质一般,比前面那个75开始的好些。使用环形USM马达,AF速度很快。价格低。
中高档:
Canon 70-200 f/4L (小小白,XXB),L级镜头,做工,成像,AF速度都无可挑剔,唯一的缺点就是光圈不够大,不过换来价格低(相对2.8的镜头),便宜。价格中
Canon 70-200 f/4L IS (XXBIS) 刚推出的,目前还没上市。XXB加了IS,不过价钱翻了一倍,恐怕要吓退很多潜在的购买者。价格高
Canon 70-200 f/2.8L (小白,XB),这个现在恐怕很尴尬了,不说也罢。价格高
Canon 70-200 f/2.8L IS (XBIS),这个是镜皇级的。价格极高
Canon 70-300 f/4-5.6 IS (小小黑,XXH),这个是个便宜的,画质不错的选择,价格中。详细信息可参见BM的blog
Simga 70-200 f/2.8 EX, 俗称小黑,和XXB相比有大光圈,但是画质不如,两者间选择XXB的更多些。价格中
Sigma 100-300/4 HSM,俗称大黑,这个镜头基本上是sigma最好的变焦头。从各方面来看都达到了Canon L头的水准。价格高(二手600多可以买到)
这个焦段以前比较受欢迎的是XXB,现在面临XXBIS和XXH的竞争。XXB的优点是便宜,画质好,轻便。XXBIS加了防抖,价格也上去了。XXH便宜,带防抖,画质也不错,但是做工不如XXB。XBIS大光圈,带防抖,是舞台摄影的不二选择,但是很重,不太适合背着出游。我个人认为新手比较适合上XXB或者XXH, 预算充裕考虑XXBIS或者XBIS。低价的话,后两个好些。
e. 人像(宝宝,领导。。。):
Canon 50 f/1.8,价格低,极低,只要70刀。
Canon 50 f/1.4,价格低,但是在各家标头里面已经最贵了,不过号称也是最好的。
Canon 85 f/1.8,价格低,这个非常超值,建议拍LD的先上这个,
唯一的缺点就是室内房子小了可能耍不开,需要配合一个50/1.4或者50/1.8
Canon 85 f/1.2L II,价格极高,不是pro或者高烧不要考虑了。
Canon 135 f/2L,价格高,但是刚刚超过800。Canon最好的镜头之一,也是地球上135镜头里面最好的之一。虽然800刀不少钱,但是觉得物有所值。
室内拍宝宝推荐 50 f/1.4, 如果预算紧张f/1.8也成,毕竟价格在那里,还能说啥?室外 85 f/1.8是新手的首选。
f. 微距:
Tamron SP 90 f/2.8 macro,价格中,新的国内便宜,或者上二手。旧款的也就200出头,还不错。
Canon 100 f/2.8 macro,价格中,但是最好的百微之一。
Canon 180 f/3.5L macro,价格高,非常好的长焦微据。
Tamron SP 180 f/3.5 Macro,价格中,不输Canon原厂,机械性能稍逊,价格便宜不少
Sigma 150/2.8 Macro,世界上唯一的超焦大光圈(2.8)微距,配合Canon卡口有HSM超声波对焦,全时手动。超焦/微据 2 in 1的选择。缺点是全开光圈稍软。价格中。
都是好头。Canon的贵些,但是有全时手动,我觉得对微距还是很重要的。建议新手先上SP90或者百微
g. 超长焦:
(感谢tyning加的这段)
其实考虑到这个焦段来的都不是新手了,不过我也写写好了,算是补全。太贵的东西就不写了。
Canon 100-400 f/4.5-5.6L USM IS,俗称大白。这个焦段各家最好的变焦头,虽然和定焦的比起来还略有差距,不过非常versatile,价格极高。
Canon 300/4 IS L,高素质的300mm定焦,配合canon 1.4x增距镜可以获得420mm/5.6的IS高素质白炮。价格高。
Canon 400/5.6 L,这个镜头素质不错,可惜没有装备IS,所以实际使用起来就要打不少折扣了,建议需要400mm高素质镜头的参考上面的300+1.4x的选择。价格高
Sigma 50-500/4-5.6 HSM,俗称bigma,非常大个。但是是地球上唯一的从50-500十倍变焦的长焦镜头,素质不错,缺点是没有IS。价格高(不过二手很新的700就可以买到)
Sigma 80-400 /4-5.6 OS,Sigma推出的和DB竞争的产品,价钱便宜350刀(此头1000刀),多出20mm。缺点是画质略逊,没有HSM,对焦速度较慢,但是有图像稳定防抖,据说和DB比效果不差。如果觉得DB太贵可以考虑这个的二手,大约700多可以拿下。
三。新手的选择
C家的镜头多,也意味着有多种搭配的可能。选择的时候,先确定你是不是有特别的兴趣,比如人像,选好特殊用途的之后,一般先挑中广,再挑长焦。资金不足,优先满足最需要的,其他的慢慢配。另外,焦段不一定要覆盖齐全,比如你有17-40,70-200之后,中间缺的那段可以暂不考虑,或者加个50的标头。下面是我比较喜欢的一些选择:
1。低价选择 1000打住
最廉价的选择: 400D 加 套头。能满足基本的需要。
超低价而全面的选择: 400D 加 套头 加 d里面一个廉价长焦。
超低价一镜走天下的选择: 400D 加 c里面4个廉价头之一,其中sigma的焦段比较合适。
这三种低价选择里面我比较喜欢第二种,因为你可以尝试从18到300,找出自己比较喜欢的焦段,升级,加强。
2。小烧到中烧的选择 (1200到2500)
如果你不想从狗头起步,而且能一次投入一些资金,或者能够忍受焦段的不全,慢慢补充,那么可以考虑:
基本1:400D 加 b里面的A16或者17-40L, 非常好的起步选择
基本2:400D 加 A05 加 A09, 广角,风景和一般的人像都cover了,A05可以换成17-40L, 但是我觉得A09是主力,所以就挑了便宜的A05。
进阶3:全方位覆盖: 1或者2 加 XXB或XXH
另类4. 一镜走天下: 400D 加 Canon 24-105L IS (有人用过么?)
我个人认为是从1或2起步,视情况加长焦比较合适。
3。大烧
这没啥好说的,买自己想要的就行了。
4。特殊兴趣
镜头概览里面已经列了特殊镜头的选择,这里就不重复了。
最后再说一句,选定了,买进了,就要想办法用好,多拍,多看多想,而不是总惦记着手头的东西是不是还不够好,等到你觉得手中东西真正限制住自己了,再考虑升级吧。

Canon 17-55 f/2.8 IS APS-C only,价格高
Tamron 17-35 f/2.8-4 (A05),价格低,二手更值
Canon 17-40 f/4L, 价格中
Canon 16-35 f/2.8L, 价格高
这个焦段因为乘1.6后变成最常用的28-80左右,对新入门的而言是应当优先配置的。这个类别里,前两个是APS-C only,A16是预算不足时的最好选择。后三个兼容全副,17-40最为一个相对便宜的L头,做工和画质都没得说,非常的popular。A05除了对焦速度和做工,画质不比最popular的1740差。现在新的价格300不到,可惜到处缺货。而且这个镜头Keh.com和各二手论坛有大量二手转让,一般成色都较新,keh能220左右拿下。实在是非常超值。如果你要大量在光线不足的时候用这个焦段,考虑17-55。16-35除了大光圈,画质和1740比没有质的提高。
我个人的推荐是17-40或者两个tamron之一。
c. 广,中广 (II):
Tamron 28-75 f/2.8 (又称A09),价格低,超值
Canon 24-70 f/2.8L,价格高
Canon 24-105 f/4L IS,价格高
把这几个镜头和前面的分开列,主要是因为这三个头的焦段在FF上更合适些, 在APS-C上有些不够广,但是依然是很好的选择。A09算是这些年Tamron风头最劲的一个头,因为比原厂头便宜一半,质量更轻,而画质只是稍逊而已。如果不介意经常携带两个镜头的话,建议与Canon 17-40L或者Tamron 17-35/2.8-4配对。这样你在17-75这个最常用的焦段 将能够获得素质极高的大光圈组合。这个头无论人像,还是风景,都有很多佳作,在本版C,N各家的持有量也相当大。24-105L是佳能新出的头,虽然光圈最大只有f/4,但是焦段覆盖更广,画质不比24-70差,还带防抖,现在比24-70更受欢迎。
如果你想搞个佳能的胶片机玩玩,或者希望一个变焦覆盖40到80这段,我的推荐是A09。
另外可供选择的不错的镜头有
Sigma 17-70/2.8-4,素质尚可,比前面的三个略差,但是足够用,一个镜头涵盖两个镜头的焦段。价格低。不过Sigma镜头一向不保值,买新的恐怕贬值很快。
Canon 28-135/3.5-4.5 IS USM,第一代IS镜头,画质不错,做工较狗。以前是穷人的最爱,不过自从Tamron的28-75出世了以后,这个镜头不那么受追捧了。价格中,不过刚过400。
Canon 24-85 f/3.5-4.5 胶片时代廉价一镜走天涯的标配, 价格低
Canon 28-105 f/3.5-4.5 据一个对比,在APS-C的DSLR上和24-105L看不出大的区别。价格低
d. 中长:
这里开始就进入Canon的强项了,所以要有钱尽管往上砸,没钱么,也有不错的选择。
低价选择:
Canon 75-300 f/4-5.6 USM III,做工,画质都一般,AF慢,唯一的优点就是价格比较便宜。价格低
Sigma 75-300 f/4-5.6 DG Macro APO,Sigma这个镜头有N款,注意要选择带APO的这个,成像尚可,比上面那个Canon得好。做工,AF速度也慢,不过价钱不错。价格低。
Canon 100-300 f/4.5-5.6 USM,做工,画质一般,比前面那个75开始的好些。使用环形USM马达,AF速度很快。价格低。
中高档:
Canon 70-200 f/4L (小小白,XXB),L级镜头,做工,成像,AF速度都无可挑剔,唯一的缺点就是光圈不够大,不过换来价格低(相对2.8的镜头),便宜。价格中
Canon 70-200 f/4L IS (XXBIS) 刚推出的,目前还没上市。XXB加了IS,不过价钱翻了一倍,恐怕要吓退很多潜在的购买者。价格高
Canon 70-200 f/2.8L (小白,XB),这个现在恐怕很尴尬了,不说也罢。价格高
Canon 70-200 f/2.8L IS (XBIS),这个是镜皇级的。价格极高
Canon 70-300 f/4-5.6 IS (小小黑,XXH),这个是个便宜的,画质不错的选择,价格中。详细信息可参见BM的blog
Simga 70-200 f/2.8 EX, 俗称小黑,和XXB相比有大光圈,但是画质不如,两者间选择XXB的更多些。价格中
Sigma 100-300/4 HSM,俗称大黑,这个镜头基本上是sigma最好的变焦头。从各方面来看都达到了Canon L头的水准。价格高(二手600多可以买到)
这个焦段以前比较受欢迎的是XXB,现在面临XXBIS和XXH的竞争。XXB的优点是便宜,画质好,轻便。XXBIS加了防抖,价格也上去了。XXH便宜,带防抖,画质也不错,但是做工不如XXB。XBIS大光圈,带防抖,是舞台摄影的不二选择,但是很重,不太适合背着出游。我个人认为新手比较适合上XXB或者XXH, 预算充裕考虑XXBIS或者XBIS。低价的话,后两个好些。
e. 人像(宝宝,领导。。。):
Canon 50 f/1.8,价格低,极低,只要70刀。
Canon 50 f/1.4,价格低,但是在各家标头里面已经最贵了,不过号称也是最好的。
Canon 85 f/1.8,价格低,这个非常超值,建议拍LD的先上这个,
唯一的缺点就是室内房子小了可能耍不开,需要配合一个50/1.4或者50/1.8
Canon 85 f/1.2L II,价格极高,不是pro或者高烧不要考虑了。
Canon 135 f/2L,价格高,但是刚刚超过800。Canon最好的镜头之一,也是地球上135镜头里面最好的之一。虽然800刀不少钱,但是觉得物有所值。
室内拍宝宝推荐 50 f/1.4, 如果预算紧张f/1.8也成,毕竟价格在那里,还能说啥?室外 85 f/1.8是新手的首选。
f. 微距:
Tamron SP 90 f/2.8 macro,价格中,新的国内便宜,或者上二手。旧款的也就200出头,还不错。
Canon 100 f/2.8 macro,价格中,但是最好的百微之一。
Canon 180 f/3.5L macro,价格高,非常好的长焦微据。
Tamron SP 180 f/3.5 Macro,价格中,不输Canon原厂,机械性能稍逊,价格便宜不少
Sigma 150/2.8 Macro,世界上唯一的超焦大光圈(2.8)微距,配合Canon卡口有HSM超声波对焦,全时手动。超焦/微据 2 in 1的选择。缺点是全开光圈稍软。价格中。
都是好头。Canon的贵些,但是有全时手动,我觉得对微距还是很重要的。建议新手先上SP90或者百微
g. 超长焦:
(感谢tyning加的这段)
其实考虑到这个焦段来的都不是新手了,不过我也写写好了,算是补全。太贵的东西就不写了。
Canon 100-400 f/4.5-5.6L USM IS,俗称大白。这个焦段各家最好的变焦头,虽然和定焦的比起来还略有差距,不过非常versatile,价格极高。
Canon 300/4 IS L,高素质的300mm定焦,配合canon 1.4x增距镜可以获得420mm/5.6的IS高素质白炮。价格高。
Canon 400/5.6 L,这个镜头素质不错,可惜没有装备IS,所以实际使用起来就要打不少折扣了,建议需要400mm高素质镜头的参考上面的300+1.4x的选择。价格高
Sigma 50-500/4-5.6 HSM,俗称bigma,非常大个。但是是地球上唯一的从50-500十倍变焦的长焦镜头,素质不错,缺点是没有IS。价格高(不过二手很新的700就可以买到)
Sigma 80-400 /4-5.6 OS,Sigma推出的和DB竞争的产品,价钱便宜350刀(此头1000刀),多出20mm。缺点是画质略逊,没有HSM,对焦速度较慢,但是有图像稳定防抖,据说和DB比效果不差。如果觉得DB太贵可以考虑这个的二手,大约700多可以拿下。
三。新手的选择
C家的镜头多,也意味着有多种搭配的可能。选择的时候,先确定你是不是有特别的兴趣,比如人像,选好特殊用途的之后,一般先挑中广,再挑长焦。资金不足,优先满足最需要的,其他的慢慢配。另外,焦段不一定要覆盖齐全,比如你有17-40,70-200之后,中间缺的那段可以暂不考虑,或者加个50的标头。下面是我比较喜欢的一些选择:
1。低价选择 1000打住
最廉价的选择: 400D 加 套头。能满足基本的需要。
超低价而全面的选择: 400D 加 套头 加 d里面一个廉价长焦。
超低价一镜走天下的选择: 400D 加 c里面4个廉价头之一,其中sigma的焦段比较合适。
这三种低价选择里面我比较喜欢第二种,因为你可以尝试从18到300,找出自己比较喜欢的焦段,升级,加强。
2。小烧到中烧的选择 (1200到2500)
如果你不想从狗头起步,而且能一次投入一些资金,或者能够忍受焦段的不全,慢慢补充,那么可以考虑:
基本1:400D 加 b里面的A16或者17-40L, 非常好的起步选择
基本2:400D 加 A05 加 A09, 广角,风景和一般的人像都cover了,A05可以换成17-40L, 但是我觉得A09是主力,所以就挑了便宜的A05。
进阶3:全方位覆盖: 1或者2 加 XXB或XXH
另类4. 一镜走天下: 400D 加 Canon 24-105L IS (有人用过么?)
我个人认为是从1或2起步,视情况加长焦比较合适。
3。大烧
这没啥好说的,买自己想要的就行了。
4。特殊兴趣
镜头概览里面已经列了特殊镜头的选择,这里就不重复了。
最后再说一句,选定了,买进了,就要想办法用好,多拍,多看多想,而不是总惦记着手头的东西是不是还不够好,等到你觉得手中东西真正限制住自己了,再考虑升级吧。

Canon EF 50mm f1.8 vs f1.4
Although both are ranked highly among portrait lenses on a 1.6x crop SLR, f1.8 is much cheaper (<$100) than f1.4 (~$300) and might be a good choice for starters. However, f1.4 has a lot of advantages over f1.8. As a long-term investment, f1.4 would probably be a better choice. There are also some other 50mm lenses from Canon: f1.2 L (very expensive ~$1600) and f2.5 (compact macro lens, but might not enough for macro photography). f1.4 might be be the best judging the image quality and price. Here are some comments from amazon.com on these lens.
1) Reviewer: Careful Critic
With the 50mm f1.8 lens available for less than a hundred dollars, why spend so much more to get the f1.4? The answer is, you may not need to. It all depends on your seriousness, budget, and how long you need your lens to last.
If you want a "starter lens" for shooting at 50mm (or with prime lenses in general), the f1.8 would be a great buy. The superficial quality is reportedly quite comparable. It might even be nice sometimes to feel as if a lens is "disposable." You could buy the f1.8 cheaply, regard it as a "play with it" lens, and get a nice introduction to "prime lens quality" - fixed-length lenses generally outperform zooms that cost substantially more money.
So if the f1.8 is such a great bargain, why would the f1.4 be among Canon's most all-time popular lenses? It's that the f1.8 can take the great shot within certain conditions, but the f1.4 delivers within a much wider range of conditions. In other words, "You get what you pay for," and we'll save the best for last.
Affordable but Solid Contruction: the f1.4 will likely have a much longer life than the cheaply fragile f1.8, and retain more resale value. It's an investment, rather than a commodity. And it'll be more certain on your camera and in your hand.
Full-Time Manual Focus: the f1.4 lets your camera autofocus, and then you can tweak further by hand without flipping a switch. The f1.8 requires switching back and forth between auto and manual focus.
Resistance to Abberation: in comparison tests, the f1.8 is more prone at wider apertures to vignetting (shadows around the corners), chromatic abbertation (color halos around high-contrast areas), and lens flare. For instance, lens flare within the f1.4 tends to be more tightly controlled - "in focus" - whereas a bright light source is more like to blow out the whole shot in the f1.8.
"Headroom": on one hand, 1.4 to 1.8 might not seem like much of a difference, and both lenses are (expectedly) "soft" wide open. But the 1.4 "gets up to sharp" more quickly ("sharp enough" by f2.0, "very sharp" by f2.8, and approaching "unreal sharp" by f4). The 1.8 can produce exceptional clarity too, but stopping down further to get it (and therefore slowing down your shutter). And when you need all the light you can get (at the expense of some sharpness), f1.4 is actually a LOT more light.
(For instance, shooting "wide open" for live performers in dim venues. Faster shutter for less motion blur. More light for better color. And the edges are definitely soft at 100% magnification, but relatively clear compared to the out-of-focus background. That "illusion of clarity" doesn't necessarily print so well, but resizes very nicely for the web.)
So the f1.8 can produce some stunning images, particularly in broad daylight and ideal lighting, but is less adaptable to challenging circumstances that the f1.4.
"The Best for Last...":
Now, with both these lenses, you get the advantage of marvelously wide aperture, which can be used for a tight focal plane that lets the background (or foreground distractions) fall quickly out of focus. This is of course a cornerstone of creative photography, and both lenses give you plenty to explore. (In practice, both deliver a pretty shallow depth of field at f2.8 in close-up shots.)
However, there is such a thing as "blur quality," called "bokeh," based on the number of aperture blades within the lens. The f1.8 has five, and the f1.4 has eight. The difference is that the blur from the f1.8 can be rather "choppy," and distant lights and specularities will appear pentagonal. Whereas the f1.4's distant lights will be more smoothly rounded, and the entire bokeh "buttery smooth."
In other words, there's more to quality than sharpness - there's also quality where your shot is LESS than sharp. And this is where the f1.4 becomes "a favorite lens" for some people, even at over three times the price of its diminuitive counterpart.
Make no mistake, the f1.8 would make an excellent "starter" lens. But the f1.4 is an exceptionally SERIOUS lens. $80 is a fine price to pay for a lens you might outgrow, $300 a worthy price for one you won't. So they're both bargains, just buy what's best for you.
(Addendum - There's also a 50mm f2.5 Macro lens at about 2/3 the price of the f1.4. If you NEED macro, it's reportedly pretty good, and for general purpose as well. But it's a) not even as fast as the f1.8, b) more difficult to manually focus, and c) not as creamy in the bokeh, with six aperture blades instead of eight. And Canon's 100mm version is better for macro work, both practically and qualitatively. The 50 Macro does become a contender, at a "middle price," if what you really need is one decent lens to do as many different things as possible, though none of them as well.)
2) Reviewer: G. Clark "hogwallow" (Houston, Texas USA)
When I worked as a photojournalist many years ago, 50mm was the "standard" lens in that it came closest to a real world perspective, especially for street photography. That is no longer always true because of the field-of-view crop of many cameras. Canon's popular digital Rebel and its successors, for example, have a 1.6X view that turns a 50mm lens into an 80mm lens. The 1D MARK II has a 1.3X view that makes it a 65mm lens.
So, if you're looking for a standard lens today, 35mm probably is closer to the mark on those cameras. And Canon has a couple of options there - a 35 f/1.4 that is great and expensive and a 35 f/2 that is a good value at about $250.
If you're still looking for a 50mm, however, there now are four options from Canon: 50/1.2, 50/1.4, 50/1.8 and 50/2.5. Here are the pros and cons of each:
50/1.2 is the newest, fastest and the most expensive at about $1,600. It is an "L" lens, which means it is more durably constructed than any of the others. The image quality is a cut above all of the others, especially at wider apertures. If money is no object, you'll probably want this one. But most of the rest of us have to ask the question whether it's 5X better than the 1.4.
50/1.4 is maligned by some for the softness of its images at f/1.4, but for me its a good, compact, low-light lens at a terrific price ($325). And the lens gets sharp quickly as you stop it down. It's sharp at f/2 and very sharp by f/2.8 with good contrast and colors.
50/1.8 is a step down from the 1.4 in speed, image quality, build quality and the smoothness and noise of its autofocus. But it is a big step up in value - a decent lens for about $80. If you're just getting into digital photography, this is a great lens to learn on until you get a better feel for the lenses that you want/need.
50/2.5 - this is a macro lens, although you can use it for general photography, too. I wouldn't recommend it. If you're doing macro photography, spend a little more for the 100/2.8, which is a sharper lens that gives you more subject distance. If you're looking for a standard lens, you'll appreciate the wider aperture of the 1.4.
All that said, of the 50mm Canon lenses, I think the 50/1.4 still offers the best mix of image quality and value.
3) Reviewer:S. Banerjee "Renaissance Man" (New York, NY)
The 50mm/f1.4 and 50mm/f1.8 are the BEST PORTRAIT LENSES that Canon offers. I own a Canon Rebel 2000 and Digital Rebel XT and have used both these lenses for several months. Pictures have been outstanding and my professional customers frequently cite the sharpness, light balance, depth of field, color reproduction, and "bokeh" (intentional blurring of background in portraits) from these lenses. Some people question the usefulness of a 50mm lens on digital SLRs with a 1.6x crop factor (i.e., 50mm lens = 80mm on a dSLR like the Digital Rebel XT)... I can vouch that the range is beautiful and relevant, focusing more closely on key subjects in portraits.
WHAT DO THESE LENSES HAVE IN COMMON? They are both fast (the f1.4 is blazing fast - dSLR can hardly keep up!), details are incredibly sharp (you can see individual hair strands), virtually no chromatic (color) aberration, no dithering or shadows in the corners, focusing is rapid and quiet (thanks to Canon's patented Ultrasonic USM technology) and photo quality parallels even my professional Canon "L" lenses. These fixed aperture lenses also provide superior pictures than telephoto lenses at 50mm because of better glass and aspherical elements.
HOW ARE THESE LENSES DIFFERENT? Having tested both lenses across 1500+ pictures, there are 5 key factors that make the f1.4 superior (justifying the $300+ price tag).
1) FASTER ESPECIALLY IN LOW LIGHT: Extra f-stop makes the f/1.4 better for indoor photos or low light. Great companion to the 480EX flash. I was able to take nearly 40 pics/min with flash and the fastest Sandisk 1GB Ultra II CF card
2) NO CHROMATIC ABERRATION, whereas the f/1.8 has slight yellowing of photos under certain lighting conditions or where edge definition is low
3) FULL AUTO/MANUAL FOCUSING RANGE: f/1.8 requires flipping between auto and manual using a switch, while f/1.4 can be manually "hot" focused/tweaked after auto focusing
4) SUPERIOR BUILD QUALITY: The f/1.8 is plastic and feels cheap, like it might fall apart anytime. The f/1.4 is metal, weighty, and is for the proud lens owner
5) CLEANER "BOKEH" - f/1.4 produces beautiful blurring of background in portraits ("bokeh") while the f/1.8 leaves less clean edges. Canon reviews suggest this is due to the f/1.4 having 8 lens elements vs. 5 elements for the f/1.8
WHICH LENS SHOULD YOU BUY? This is a question of utility vs. value. The f/1.4 costs over $300 while the f/1.8 can be acquired for under $75. The f/1.4 will last forever while the f/1.8 will probably break under normal use in a year. Does this justify the 4x price tag? If you are a budding photographer looking for a "play lens" then the f/1.8 will more than over-deliver. If you are a photo enthusiast who looks for "the perfect shot," you will want the f/1.4 because it surpasses every expectation (and so you're not left wondering, "what if"). If you are a photo professional, you already have the f/1.4 lens among your bag and are not reading this review. :-)

PhotoShop上图简单教程 III
From 色影无忌

发表时间:2003-12-09
第三节
1,找回丢失的暗部细节(需ps8.0即ps cs)
电脑屏幕不是最好的图片载体,很多暗部细节我们在屏幕上并不能看到,这些细节在那儿,可是我们看不到,岂不是可惜了。这儿我们就来讲讲怎么把他们找回来。 看这张图,曝光时,树已经超出来ccd的宽容度,树干上还是否有细节呢?
方法很简单,利用PS8的新功能Image>>Adjustments>>Shadow/Highlight(图象>>调整>>阴影/高光),参数amount是调整的量,tonal width是你定义的暗部范围,radius是调节的每个象素所影响到的半径, 暗部细节回来了亮部却没有受影响。

2,使用ps简单的模拟80、85等滤镜(需ps8.0即ps cs)
不喜欢阴天的冷调?那就在镜头前加一片85滤镜。不喜欢阳光下炽烈的暖调?那就加一片80滤镜。当你的片子想要特定的色调来表达气氛时,你会用到这些滤镜。令人兴奋的是,现在,你可以直接在ps中模拟这些滤镜的效果了。还是刚才的片子,试一下80滤镜的效果。方法是Image>>Adjustments>>Photo Filter(图象>>调整>>图片滤镜)
效果:
这是另一个例子
这是level>>增加饱和>>85滤镜后的效果

3,更好的锐化方法
影响上图质量的最大的因素就是锐化。一般我们在上图前总是先把图片缩小到合适的大小,然后锐化。这是用这种方法得到的图片
现在我们来尝试一种更好的锐化方法:分步锐化。来试试新的锐化方法。先不要改变图片大小,把图片缩放(用放大镜)到你上图时大致的尺寸 做一次USM,把amount设在300左右,threshold在0-10之间,然后调节radius(1-4之间),直到满意的效果为止(可以略过一些)
然后再缩小图象到你要的大小(这个例子中为宽边700),然后再做一次USM,amount为0.2-0.4,radius在50-200,threshold为0 。看看这样锐化的结果^_^

第二部分
自己动手给图片加边框
网上有很多可以用来给照片加边框得程序和atn,但是总免不了千篇一律,所谓授之以鱼不如授之以渔,今天我们来讲讲自己动手给图片加边框的方法。 我们把常见的边框分三种,尽量用最简单的方法达成。
1、简洁边框
2、立体边框
3、艺术边框
先看一下原图吧

1、简洁边框
第一步,如图,复制背景层,方法是:把背景层拖至层面板下的新建图层按钮
第二步,把背景层填充成单色,方法是:选中背景层,设置前景色,按下ALT+DEL
第三步,Image>Canvas size(图象>画布尺寸?)
长宽分别设置120,单位是百分比。 这是一个最简单的边框
第四步,继续给这个边框加黑线
按住Ctrl,在层面板上点击前景层,获取画面大小的选取。 选中背景层为当前层。(这是为了让我们下面描的黑边都出于背景层上,以便为我们后面制作立体边框的需要) 。Edit>Stroke(编辑>描边):宽度设置2,颜色设置为黑色,位置为outside,其他默认,OK。 按下Ctrl+d取消选取,按Ctrl+A全选。 Edit>Stroke(编辑>描边):宽度设置1,颜色设置为黑色,位置为inside,其他默认,OK。 这是最常见的带黑边的边框。

2、立体边框
制作立体边框非常简单,接着刚才的第四步再做如下操作(参数如图)
效果

3、艺术边框 我们来介绍一下最简单的制作艺术边框的方法。 在制作简洁边框的第三步完成后,按住Ctrl,在层面板上点击前景层,获取画面大小的选取。 找到Path(路径)面板,make work path(生成工作路径)。
选中橡皮擦工具,选择你喜欢的笔刷形状及合适的笔刷大小,按下Stroke Path with Brush

自己动手给图片加边框
网上有很多可以用来给照片加边框得程序和atn,但是总免不了千篇一律,所谓授之以鱼不如授之以渔,今天我们来讲讲自己动手给图片加边框的方法。 我们把常见的边框分三种,尽量用最简单的方法达成。
1、简洁边框
2、立体边框
3、艺术边框
先看一下原图吧

第一部分
今天先讲简单中的最简单部分,希望摄友们能集思广益,把这个帖子慢慢补充完整,好让广大泡菜自己动手,丰衣足食。 先把上图前的PS工作简化至极,分六步走。
1、Level(色阶)
2、Curves(曲线调节)
3、Channel Mixer(通道混合器)
4、Crop(裁剪)
5、USM(Unsharp Mask)(锐化)
6、加框
下面咱们就一条一条的学习。 本贴由于本泡菜自身水平的限制,有疏漏及错误之处敬请指出。 先来看一下例图。这张图片用摄友们常用的话来说就是像蒙着一层雾,不通透。另外颜色似乎也不够饱和。

1、先来讲讲level (色阶)
PS菜单下Image>Adjustments>Level(图像>调整>色阶)是一个很常用的命令,可直接按CTL+L呼出。 要熟练使用Level(色阶)命令,理解Level图形是必须的。 可能你会觉得Level图形很眼熟,没错,它跟我们平时用DC时看到的直方图非常相似。 Level图形一般以下几种常见形式。 最常用的调整方法如下。
这是对例图的level操作。可以看到,灰蒙蒙的感觉已经大为改善,片子的反差比较正常了。

2、Curves
Image>Adjustments>Curves(图象>调整>曲线调节)也是PS中常用的命令之一,可直接按CTL+M呼出。 看一下最简单的curves操作。
这是对例图的第二步操作,curves 将图象略微调暗并增加反差(你也可以对单一通道进行调整)

刚才讲到例图的颜色似乎不是很饱和 一般在PS中调节饱和度常用的命令有两条:
Image>Adjustments>Hue/Saturation(图象>调整>色相和饱和度)
Image>Adjustments>Channel Mixer(图象>调整>通道混合器)
我们来试一下比较常用的Channel Mixer 。假设(仅假设)我们觉得例图的蓝色不够饱和。可以试着做如下调整。 这里解释一下Channel Mixer工作原理。 假设图中一个象素的原色值为R200,G100,B50,则做一下调整后该象素的色值变为R200,G100,B=200×5%+100×5%+50×108%=69。

Crop本身没什么好说的,讲两个小技巧。 a:PS中拉任何形状,按住shift是正方或正圆。改变选取时按住shift是保持比例。另外,移动对象是按住shift是平移。 b:做crop是有时候需要裁掉图象边沿一小条,而鼠标经常会被图象边沿吸引,无法移动,此时按住Ctl键摆脱边沿引力。
5、USM(Unsharp Mask) (锐化)
Filter>Sharp>Unsharp Mask (滤镜>锐化>USM锐化)
USM滤镜的三个数值分别是,锐化权值、半径、阀值。三个数值的准确解释是比较抽象而难以理解的。 一般我们都使用自己的习惯数值或者在习惯数值附近调节。对一张500×700左右的图像,我的常用配合是Amout75,Radius0.9,Threshold3。你可以在此附近调节试试。当然对于不同的图像,理想的数值配合会有不同。
6、加框
最简单的加框操作是先将前景色设置为边框颜色,然后做Image>Canvas Size,长宽各设为105%-110%。 如果你需要相对复杂的边框,我们下一节课继续开讲。 附效果图一张。
说明一下,此效果并非最完美版本(在笔记本液晶屏上调整所得,颜色可能有偏差)。所谓各花入各眼,最终结果视乎操作者自身的欣赏角度。也正因此,摄友们更加应该武装自己,摒弃千篇一律毫无个性的只能软件。

发信人: tyning (Mon Sep 11 02:54:22 2006)
入门书:
1。 首先就是著名的纽摄了,也就是著名的纽约摄影学院教材。这本书其实没有英文版,英文版是他们的内部讲义,被翻译成中文并且编辑以后成了上下册两本书。很多大牛其实对这本书颇有微词,觉得这本书条条框框太多,全照着学束缚思维。不过我觉得如果你要是光圈,快门,景深和基本的曝光,构图以及色彩,光影的搭配原则都搞不知道的化还是读一读启个蒙比较好。
2。 Exposure,一本很经典的曝光,色彩光影搭配的入门书,拍landscape的启蒙教材。

中级书:
当你拍了几千张照片,上图的时候能判断自己的照片是不是值得show的时候,你该看看中级的书了。这里分几个门类介绍一下。
风光及landscape
1。 The Art of Outdoor photography -techniques for the advanced amateur and professional by Boyd Norton
2。 John Shawn的一系列数,包括landscape, marcro等等
其实我更喜欢第一本,John Shawn的书感觉太具体化,有点step by step的感觉。不过对于一个身边没有老鸟可以跟着学的人,John Shawn的书能教你如何使用一些特殊的gear,比如marco那本书里面,从extension tube,到macro adpater,到macro lens,到flash bracket和ring flash都讲的很具体。Norton的这本书显然更着重于摄影本身。而且Norton是Nuclear Engineering出身,后来高了摄影,他的书对于理工科的脑子看起来更有意思些。
户外人像
1.一本基本的讲pose的书,至少可以帮助你避免一些难看的posing: Digtial quick guide: Posing techniques for digital portraits by Jeff Smith, Amherst Media
2.一本讲out door portrait布光和光线选择的书Lighting and exposure techniques for Outdoor and location portrait photography by J.J. Allen, Ameherst Media当你拍了几千张照片,上图的时候能判断自己的照片是不是值得show的时候,你该看看中级的书了。这里分几个门类介绍一下。

影室布光
1. New product shots, Roto Vision 出版的。讲怎么用影视灯布光拍些小玩意,拍出灯箱广告的那种效果。每幅照片都配有摄影师的tip以及布光图,学起来挺好玩的。不过有些复杂的布光对器材的要求甚高。
题外话,这本书是Roto Vision的Pro-lighting系列中的一套,我都在图书馆借来看过。包括: fashion shots, new product shots, black and white shots, night shots, portraits, glamour shots等等基本,都挺好的。
进阶的书
landscape和outdoor 自然摄影的
极力推荐Freeman Patterson的基本书:
1. Photography of Natural Things - A nature and enviroment workshop for film and digital photography
2. Photography and the art of seeing - A visual perception workshop for the film and digital photography
其实到了这个时候,看书和学习已经很难直接提高了。能不能真正的形成自己的摄影风格和独特的观察事物的角度要看自己的悟性和天赋了。不过看看这两本书或许能找到些hint。再有一本就是他的Photo Impressionism and the subjective image, 这个就有些玄乎了:)
喜欢扫街的
极力推荐Elliott Erwitt 的snaps看完了以后,就会发现网上大多数人拍的所谓扫街片其实就是些没啥内涵自娱自乐的东西,扫街不要扫得很有技巧,但是要扫得有内涵:)
喜欢拍人像的
人像其实真没什么高深的技巧,所以才被绝大多数pro用来做混饭吃的工具。到了这个阶段你该做的是找个好的MT,找个好的化妆师多拍了。
