it was a surprise knowing thislens wasnt too old. Probably sigma listened to JohnG:blah:

style="BACKGROUND-COLOR: #000000"Wish they had added their OS into this lens.

No, if they listened to me they would go back to the "old" (non DG, non macro) version and drop the price back to $650. I'm guessing they're fixing what they broke when they re-designed the lens to add macro.

What did they break?
It looks like they swapped the # of elements and groups around! :lol::-):-)

-> On another note - They can may be "fixed" their excellent 100-300 f/4 into a 200-400 f/4... Canon has nothing like it and this would considerably undercut Nikon (and I don't care for IS if that makes it easier for them) ;)

yep, and there have been a lot more complaints regarding performance with the new versio. Of course, complaints are difficult to judge - every bad photo afterall is the result of poor equipment :G

Still, there must be something to the complaints if they're offering a vII so soon afterwards.

@johng..

i am absolutely sure it was you who changed sigma mind to bring in some "Missing" quality in that earlier version that they released another one so soon.

:G

I'm more curious about the new Tamron 70-200mm f/2.8 (if they ever get around to shipping them).

It's a lighter lens compared to the Sigma (more composite type material from the sounds of their press release). Maybe that will make it less expensive, too. lol

We'll just have to wait and see how sharp it is and how it's AF speed stacks up (which is going to depend on the camera body focus motor in the case of Nikon, Pentax, or Sony models, or a non-HSM type motor in the case of Canon).

Can your A700 AF to f/8 (i.e. mirror lens) ? ;)
-> I was quite delighted to find out Nikon non-pro bodies can AF to f/8 as well...

BTW great review with a 'slow' lens here: http://www.luminous-landscape.com/re...%20-A700.shtml

It's intresting to know that Macro version of that lens has issues, especially after buying an old (unused, full warranty) version from a Canon dealer here.

I've choosen a great sample, sharp as razor at [email protected], precise AF.

A actually decide this lens over used f2.8L since there was a rebate on these old lenses from an importer. I got it for 650. Quite a bargain for a favourite lens.

It's a pitty I can't find 2x tcon to try it, since it's a fabulous sample.

Yep.. I've been impressed with the AF speed and accuracy of my A700. It's a very nice AF system.

According to Pop Photo's tests, the A700 "focuses faster than the Canon EOS 40D, Nikon D80, and Nikon D200 down to EV 4, then gives up a fraction of a second at EV 2 through -1. It's slower than the Canon at EV -2, but faster than the Nikons. And it focuses faster at all light levels than either the Pentax K10D or the Olympus EVolt E-510"
