人像首选应该是135L F2.

说多点,我觉得85L半身,135L全身。但要都拍半身,估计差别也不大。但全身85L锐度不行。

传统上说135之所以合适(说全幅的焦距),是头像的肥瘦适中。越长焦拍出的人越肥,也少了立体感。

这是借的的手动Contax头加佳能转接环。

金属材料的手感是一流的。

应该是Contax接口,副厂的Tokina图丽 AT-X 90mm/f2.5 macro吧,比contax镜头便宜多了,但当年曾被评为19款顶级镜头之一,有一定的实力,

多谢HOGO帮忙,拿了一套微距片,实际放大也不多,不过质量保证就是了。3片一起用还差一点点达不到1:1(可以自动对焦的),不用时是1:2的微距头。严重推荐这个头,一头多用。这个头的螺纹(Filter Threads)是金属的,其它几个50头(1.2,1.4,1.8)都是塑料的。失真也最小,看下面LINK。

看介绍是不错。

现在是不是有个趋势是把微距与普通的合在一起呢?会不会顾此失彼呢?

10528两家都是带聚焦范围开关的。

10528那是更专门的微距头。我这个只是个兼职的微距头。主要当标头用。

我借网友的学习头为什么只能微距别的一概不行呢?

真要拍活的东西估计还得上180以上的。

是个微距头还是套环?微距头都能聚焦到无穷远的啊。聚焦范围开关就是使得对焦快点,不会进误区。因为你知道聚焦的距离范围,一些长焦头也有。
另外,那些镜头标有MACRO的变焦头不算微距头,只是带有微距功能,拍微距时不一定能自动对焦的。

Canon 50mm f3.5手动头,用了闪光灯。应该是在单反上设定的3.5光圈吧。

交作业啦。

景深还是没掌握好。因为焦平面在表面上,虽然光圈小到32但是前景深还是不足。似乎焦到表针比较理想。
