Tokina 28-80 f/2.8 vs Sigma 17-70 - test shots

Hi everyone,

One of the people on these forums expressed an interest in my Tokina ATX-Pro 28-80mm f/2.8 lens, which has been sitting in the cupboard for a while. Since he is over the other side of the world, I thought it might be wise to take some test shots so he could see exactly what it was like.

I did a series of (pretty slap-dash) test shots of the Tokina vs my Sigma 17-70mm f/2.8-4.5 lens. If anyone's interested I put up a website with them at Tokina ATX-Pro 28-80mm f/2.8 tests.

The general conclusion was that the Sigma holds up pretty damn well in the comparison. The Tokina is pretty good at 28mm but is noticeably softer when wide open (f/2.8) and zoomed in, but sharpens up dramatically stopped down.

I've heard that the Tokina is pretty hard to come by in the Pentax mount, so if anybody is curious, have a look!

It wasn't very scientific or anything, some shots were hand held, focus changed a little bit, and the lighting was changeable due to passing clouds, but it might still be useful to someone out there.


Cheers,
Chris
