最近更新了Canon 5D3，以前一直玩的是变焦头，长期泡屋脊，看着各位的种种牛定的毒片，终于忍不住毒发，想试试定焦了；现有的镜头都是变焦，大三元一套外加EF 24-105/4L IS ,17-40/4L,两只，等于小三元的部分吧；现在的想法是也想留着，毕竟变焦头感觉是方便。
自己拍的片子最近也粗略翻看了一下，题材涉及风景、人像、人文三方面数量差不多，这也是自己都喜欢的题材，当然也少不了旅游照，家庭照。需求基本上是这样。
再来说说对定焦的选择：
1、EF 24/1.4 L II USM（2008）
2、EF 35/1.4 L USM（1998）
3、EF 50/1.2 L USM（2006）
4、EF 85/1.2 L II USM（2006）
5、EF 14/2.8 L II USM （2007）
6、EF 200/2 L IS USM（2008）
现在基本选定前四个头，基本涵盖广角到中远，感觉日常应该够用了；第5个超广角担心自己驾驭不了，想先用16-35再练练16端再上，还是喜欢超广角的。
至于第6个220觉得自己中毒还不够深，价格也高不可攀，暂时不想，年初也刚更新了小白兔，暂且还是玩兔子吧。

前4个头要上也要一个一个来，玩儿熟一个再来一个；从焦段上来说本来想是第一个先上35的头，本人很喜欢这个视角，但是总觉得这个头太老了，最近也传出“感动”要更新此头，所以想等等。

剩下的3个就有些想不明白先后顺序了，有请诸位泡菜、资深就24、50、85这三个头的先后购买顺序参谋参谋。。。。。

在下先在这里鞠躬致谢了！！！

这种陈年旧贴都能翻上来，不容易啊。看看几年前的帖子，再看看现在相机技术的发展和进步，真是感慨啊。楼主现在还玩相机吗？可否实现了全定焦的梦想？

看到这种帖子，一定是多年前的旧贴。时代变了，定焦已经变为小众产品。

定焦值得收藏，有银子的就都买了

谢谢蓝色响马，出去了一阵子，没有关注帖子，致歉

真是屋脊放毒无处不在，哈哈、、、坚决不吸毒、、、不入蔡司门、、、不作德系人、、、

可以考虑下副厂的ze口的镜头啊。
zeiss 的ZE系列就很不错哎。我转些文字您看看：
这个是新出来的最广的一个广角镜头：
Distagon T* 2,8/15
Widen your imagination

With a field angle of 110°, the super wide-angle Distagon T* 2,8/15 is the ideal companion when it comes to capturing events in a way that makes them dynamic and extraordinary. Whether salt crystals or drops of water – its integrated lens shade and standard filter thread afford the front lens optimal protection from wind and weather.

The technically impressive features of the Distagon T* 2,8/15 include extraordinary chromatic aberration correction as well as two aspheric lens elements, special types of glass with exceptional partial dispersion and a floating elements design guaranteeing high image quality from close-up to infinity. Allowing you unlimited possibilities to let your imagination run free.

Distagon T* 2,8/15
Design

When wide angle views go to extremes and beg the control via an SLR viewfinder, which means that the back focal distance has to be much larger than the focal length, a retrofous design called Distagon is the right choice.

Distagon with 15 lens elements in 12 groups
Lens with aspheric surface
Lens made of special glass with anomalous partial dispersion
"Floating Elements" design
Distagon T* 2,8/15
Features

Aspherical design
The aspherical lens design ensures consistent imaging performance throughout the entire focusing range as well as sharpness to the periphery of the image. The asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations compared to a simple lens.

Floating Elements Design
State-of-the-art camera techniques and high-resolution digital image sensors increasingly demand more from the lenses. The modern floating element design compensates aberrations of the Carl Zeiss SLR lenses at different distance settings. This is accomplished by changing the axial distance of single lens elements or element groups to each other. The adjustment of the element distance is coupled to the distance setting so that it always results in the right correction. The mechanical design of these lens elements is very complex and the workmanship must be particularly exact – both specialties of Carl Zeiss.

Excellent resolution and high contrast
Rich, vibrant colors are vital to creating a lasting impression. Stray light in the lens, however, would lead to a brightening of the image, which is particularly visible in shadow areas. Image contrast is lowered; the image appears dull and bleached. We combine various, elaborate techniques to reduce unwanted stray light.

Virtually distortion-free optics
Dramatic perspectives and a view from extraordinary image angles – SLR lenses from Carl Zeiss open up new composition possibilities. Distortion would disrupt the composition because straight lines, whose image does not go through the image center, would be reproduced with a curved shape.  This annoying effect is accordingly and largely compensated through elaborate optical designs at all focal lengths.

Homogeneous image quality throughout the image field
ZEISS lenses are famous for their extraordinary image quality. Even with challenging subjects, perspective, color and light are optimally rendered – throughout the entire 35 mm image field. For this reason, we place great emphasis on particularly high image quality, e.g. low distortion and outstanding stray light reduction for rich colors.

有什么好纠结的，三大元都有了。加两个定焦偶尔搭把手就好了。24+50+135。24能补16-35的缺口，50能补24-70，135能补70-200。再上个增倍镜 就玩大发了。不过单24+50+135也够了，单大三元也够了。钱多就上，我是觉得这样烧没意思，极端情况毕竟少。其实大三元加个35足够了。很多人只是上述配置的一种，大三元/24+50+135也很够用了。请永远记住不要为了补齐焦段去买镜头。摄影其实很简单，用好一两个主力就够了。别的镜头基本是睡睡觉的。喜欢搞收藏的除外。

本意是：1、35mm，2、85mm，3、24mm，4、50mm，5、14mm这个顺序的，可现在35mm要等等，其他的还按这个顺序感觉不对劲

重新排序：1、50，2、24，3、85也不妥；1、50，2、85，3、24，也不顺

所以纠结

看注册日期就知道是老玩家了 应该有自己的答案

300/2.8

此话怎讲？

LZ已经有大三元了……

兄弟莫怪 小弟直言了 你不适合玩摄影

有米啊，别犹豫了，都收了吧，不会后悔的

起点蛮高的嘛，那就都买了，再买大三元，全部都买了，绝对值

没人说说吗？

进5D3时1DX还没有出来，同时也觉得1D系列是面对专业选手的，自己是业余爱好还用不到顶级机身，所以从来没打过1D系列的主意；玩儿过朋友的1Ds3，感觉好多功能自己用浪费了，也感觉太贵了，所以从来没想过。

另外可能是个人习惯，买回来的器材不习惯再出掉，所以也不习惯买二手器材。

谢谢，呵呵

镜头选择与作品联系不紧密吧，呵呵

有米之人无需纠结买了不喜卖了再买就可。 其实何不把5D3换成1DX呢？

楼主把你在“风景、人像、人文三方面”中你个人认为的最满意的照片贴出来几张，让大家看看如何？
