I'm looking into buying either the Sigma 70-200mm 2.8 or the Tokina
80-200mm 2.8 lens (the Pentax version is way out of my price range). Do
any of you have thoughts on either of them? I shoot alot of action so
auto focus speed is really important to me.
SP I tried both on Nikon D70. Tokina has worse sharpness than Sigma at open
SP apertures and has much higher chromatic aberrations (probably because Tokina
SP uses just 1 ED element while Sigma 4). And Sigma has much faster AF thanks
SP to true IF, is lighter despite having very good build quality

I too found out a lot of purple fringes - I attributed it to flare
though. God knows what it was. But remember that the Sigma in Nikon
mount uses HSM - their equivalent of ultrasonic motors. These do make
the focusing a lot faster, especially on a body with

Interesting :-) So much about the hype of ultrasonic motors. They can
do just as well with normal ones.
Yes, it seems so. Maybe the difference could be seen more clearly when we'd
compare bigger lenses with heavier mass to move? For me the only good side

Canon has downgraded perfectly damped mirror from 10D :-( Costs

I have the manual focus version of the Tokina (ATX).
I like it a lot.

CRB You can't go wrong with the Tokina.
CRB Solid construction and fine optics.
I have had bad luck with several 20-35/2.8 ATX tokina I tried - really
soft up to 5.6 (due to spherical aberation and coma)
Which was a pity - I would like that fast while compact lens.
It might be that all were bad
it a lot.

Both are reputed to be good. I have the Sigma and would say that it is
superb, even wide open.
The Sigma rates better on Photodo. You might query Photozone also.
According to Photodo, the Sigma is actually sharpest at the long end,
while the Tokina is sharper at 80 and 135 than at 200 -- but

Hello David,
You didn't mention the body you are going to use. I think that may
have some impact on autofocus speed, along with the lens.
I have the Tokina ATX AF version, but have not seen or used the Sigma
so can't compare. The Tokina is internal focus and zoom so I would
suspect that it
