Canon vs Sigma for 70-200mm/f2.8
ŻuÁVż|
: : ps:那次我跟同學借sigma 70-210 f2.8(也算大炮級吧)very impressive
: : 對焦不會輸canon超音波太多!
: Sorry to disagree with you. I own Sigma 70-210 f/2.8 plus a few
: Canon EOS USM lenses, and I hate to say that Canon USM lens is much
: better than Sigam in terms of AF speed, accurary and noise. Sigma
: lens's AF IN EOS BODY is roughly at the stage of Canon AFD lens,
: good but not excellent.
: The Sigma 70-210 f/2.8 (82mm version) optical system is simply
: excellent, very sharp. Its color rendition is a little cool which
: is balanced out by using B+W KR1.5 filter. Pricewise, it's
: a good buy except the potential reliability problem.

你的意思是說：Sigma的那一隻鏡頭在對焦、準確性、噪音上都不
會輸給Canon那一隻嗎?
又您所謂的potential reliability problem是指那一些呢?
是不是若要買Canon 70-200/f2.8的話不如去買Sigma的那一隻?
我想很多網友都很想知道答案說……(me too)
Thanks in advance!

NOPE. Canon is much better than Sigma. EOS mount Sigma's 對焦、
準確性、噪音 are adequate for general purpose but NOT for sports.
To give you a rough idea about it, EOS mount Sigma's AF, accuracy
and noise are a little better than Nikon 80-200 f/2.8 on F90X.
: > 又您所謂的potential reliability problem是指那一些呢?
* Incompatibility w/ future Canon bodies
* Broken parts if dropped to ground
* Loose parts
* Not very realiabe, malfunctioning in 1 to 3 years
The early 77mm version Sigma 70-210 f/2.8 has some of the above problems.
My 82mm version seems to be o.k. in the past two years.

I'd recommend Canon 70-200 f/2.8 wholehearted. It's a beauty w/
quiet, fast AF and can be coupled to Canon 1.4x and 2x TCs.

I bought Sigma because my applications are mostly still lifes such
as landscape, vacation and family portraits. Remember the 82mm
filters are expensive for Sigma. If you have money, buy Canon.

Optically, Canon might be a little bit better Sigma according to
reviews. In other despartments, Canon is simply superior than SIgma.
