Tokina 28-70 f/2.8 AT-X AF 2.8

heavy lens that can get sharp shots,well built, No its not a 2.8 nikon.... THIS IS A NICE FX LENS.NO ITS NOT A NIKON BUT IF YOU WORK OUT WHAT IS BEST settings for SHARP THEN ITS GREAT.iM USING IT ON A D600 AND D2HS.SO FAR THE BEST IS F11 ON THE D2HS AND THE D600 LIKES JUST ABOUT ALL SETTINGS.MINE IS NOT THE SV MODEL I BOUGHT THE ONE WITH THE SCREW IN HOOD NOT THE BAYONET MODELS.I PAID 250 AND HAVE SEEN THEM CHEAPER BUT THIS WAS PRISTINE.BUILT LIKE A TANK.FEELS GOOD ON THE D2HS WELL BALANCED.With the 1.5 crop on dx its a handy 2.8 roughly 45-100 .on the d600 its a little front heavy.transition from auto to manual is a easy push pull motion.this web page says it all.yes id rather have the equivalent nikon but its out of my range.good accurate focus. http://www.johncaz.net/blog/tokina-at-x-pro-af-28-70mm-26-28 sorry for the caps

Great all around lens that covers a wide variety of shooting needs! I bought this lens as a new hobbyist/photographer wanting more versatility than my kit lenses provided. Just love it. It is now my GO TO lens. I love being able to blow out the background a bit by using a wider aperture than my other lenses allowed but being able to also change depth of field and shoot other situations without changing lenses. Works fabulously with my Nikon D70. Since my camera's a little older, I wasn't certain the auto focus would work on this Tokina, but it works beautifully! Couldn't be happier.

This is a great portrait lens This is the version that's based on the Angenieux optical formula that Tokina purchased. You can pick it out from the rest of the Tokina 28-70 PRO AT-X lenses from the screw on lens hood. Most of the reviews I read claim that it is super-sharp, even wide open, and I wanted a medium zoom lens with an f2.8 aperture. I was initially disappointed with the one I bought, as it seemed very soft overall. After testing for a few days, I find that this lens is nicely sharp in the middle, with f4 and greater, the edges tend to be a bit soft at most f stops (but you shouldn't have details in corners anyway). Mine also has a pretty strong ghosting/flare when it's at 2.8 and shooting a high contrast subject, which seems to go away by f4. I tried it for landscape photos, and it's actually terrible until you get up to about f11, otherwise the ghosting makes for very low contrast photos. This is why my first impressions were disappointing, I was using it for the wrong subject. I think the best part is the smoothness of the out of focus parts of the image (bokeh). When shooting subjects against an interesting background at f2.8-4, the background is dreamy smooth, and the highlights are nice circular spots. It makes for some interesting flare spots, and with a high fstop, if makes decent stars. All these put together makes for a wonderful portrait lens, or close up work (but not highly sharp macro) where you want the background smoothed out and beautiful.
