17-40 is not really a conventional portrait lens. Between the 2 choices, 24-70 is better.

Conventional range is 70-135mm (135mm/FF).

Sigma 24-70mm F2.8 IF EX DG HSM
Canon EF 17-40mm f/4L USM

以上兩支相比, 一定係sigma果支, 因為canon果支f4起跳, 焦距又唔係咁match人像標準50mm, 最佳成像要去到f8以上, 記住canon出呢支17-40係for影景用的, 主要影人就 sigma 24-70 or canon 24-70 吧!!

如用在APS-C機,50 f/1.4還是85 f/1.8好呢?兩支的評價都是很高,價錢也差不多

[Obi-Wan]

人像最好有creamy的bokeh, sigma 1.4值得 考慮，85／1.2 同50/1.2 @1.2 景深太淺同太soft

不過我個人認為最正嘅FF人像鏡王係minolta 135 STF

兩支我會選８５．８了，鏡設計好Ｄ，唔會對焦時伸縮，ｕｓｍ又係堅野，非ｍｉｒｃｏ類

[Panda1802]

h0001244兄,micro USM跟ring USM有什麼分別?
是否在唔會對焦時伸縮
那一種較好?

In normal confortable distance for 1.6x camera -

50/1.8 is for normal half body
85/1.8 is for shoulder shot

Just a general idea.
