枫下拾英 / 摄影艺术 / QUestion: Cannon lens EF-50, f/1.4. what's this lens for? I mean what kind of shooting best suing this lens? thanks for any input! -jqkmm(taste); 2010-7-16 (#6179944@0)

thanks, but sorry, it should be EF-50, f/1.8 II. what's this lens for? -jqkmm(taste); 2010-7-16 (#6181063@0)

50mm f/1.8 : Poor; 50mm F/1.4: less poor. 50mm F/1.2: not poor -zbt(周伯通); 2010-7-20 (#6187299@0)
it is cheap -sky2005(Fenix); 2010-7-20 (#6187306@0)

任何厂家的标头都是最便宜的好头。没有钱就上50/1.8，有钱就上50/1.4。什么都可以拍，不只限于人像。我就喜欢带一大堆定焦. -ding_ding(丁_丁); 2010-7-20 (#6187296@0)

thanks. but i think it's too wide for me. i'm not professional at all. so choose from 17-40 or 15-85, i think it's enough for me rihgt now. recommendation? -jqkmm(taste); 2010-7-26 (#6196730@0)

短期内计划上全副的话，17-40。否则15-85 handsdown!!! 对APS-C更实用,广角段更宽(15 vs 17, 2mm makes HUGE difference)，望远端更远，有IS, 非常好的walkaround lens -genjurok(Genjuro); 2010-7-27 (#6198307@0)

so reasonable. for walkaround, I'm thinking about 24-105. if so, what do you think of the difference between 85, and 105 ? is there also huge difference? thanks -jqkmm(taste); 2010-7-27 (#6198512@0)

i'd choose 15-58. 85 vs 105, magnification factor wise, not much difference. it's a different matter for wide end, 15 and 24 are two completely different things. 24 isn't wide enough in many cases : you simply can't get the shot! -genjurok(Genjuro); 2010-7-27 (#6199846@0)
if you're planning to go FF soon, then 24-105 is better. otherwise, 15-85 is probably the best choice for walkaround lens on APS-C (in the canon world of course :D:D:D) -genjurok(Genjuro); 2010-7-27 (#6199861@0)

thanks for your opinion. i read some reviews on photozone, according to their review and test, 15-85 is not as good as 24-105 or 17-40. -jqkmm(taste); 2010-7-28 (#6200531@0)

见仁见智了。L当然有优势，但用在APS－C上并非总是比EF－S镜头更适合。比如作WALKAROUND（避免换镜头的麻烦），２４－１０５的焦段就有些尴尬，想宽而宽不下去没法拍东西的难受，比画质的一点差异大多了。 -genjurok(Genjuro); 2010-7-28 (#6200646@0)

Em.. will think it over. by the way, what do you think of the distortion. I'm not profeesional, but I saw the sample of some pictures, distortion is really a big difference. but I want to know how is it when we have walkround shooting. -jqkmm(taste); 2010-7-28 (#6200725@0)

我不太在意distortion，因为canon的镜头后期可以矫正，另外除非拍建筑物，distortion并不明显或者不annoying。在２４mm端，这些镜头应该都不会有明显distortion。问题是１５－２３，能不能拍到？你是否经常用到这个焦段？ -genjurok(Genjuro); 2010-7-28 (#6200779@0)

thanks for your experienced opinions. shooting for me is mostly like for person and landscape while we are travleling. secondly is for indoor shooting and street shooting. maybe 10-22 and 24-105 is kinda combo for me? any comments are so welcomed. -jqkmm(taste); 2010-7-28 (#6200956@0)

10-22 24-105应该是很好的组合。indoor光圈速度或许不足，另外旅游通常使用广角多于长焦，有的时候你或许得被迫换到10-22。我自己会选择15-85（旅游镜，广角到小望远，IS，USM），加sigma 30 f/1.4（光线暗，indoor，还有肖像） -genjurok(Genjuro); 2010-7-28 (#6201096@0)

thanks, let me do more research. I'm learning on choosing the proper lens for beginer like me. meanwhile i don't want to think of upgrade so soon. that's why even i'm a newbie, i still prefer to buy a advanced for me. -jqkmm(taste); 2010-7-29 (#6203151@0)

我也曾在这两个镜头选择，我的是T2i，看了网上的测评和片片，蜂鸟摄影论坛有很多照片、比较。我最后进了个17-40mm. -worldy(.); 2010-7-28 (#6201366@0)

would you like to share your experience here? thanks -jqkmm(taste); 2010-7-29 (#6202809@0)
by the way, you mean 17-40 vs 15-85? -jqkmm(taste); 2010-7-29 (#6202815@0)

是这两支镜头。其实根据我的情况15-85mm的焦段更适合我，但还是17-40 的成像、色彩更诱人。 -worldy(.); 2010-7-29 (#6203424@0)

thanks. this is what i'm concerning. then which one you use a walk around lens? -jqkmm(taste); 2010-7-30 (#6204390@0)
