Tokina 20-35mm F2.8 AT-X 235 AF PRO A-mount lens review by 3.0
|3.0#10733 date: Nov-28-2012|
flare control: 4
|ownership:||I own this lens|
|compared to:||Tokina 28-70mm f/2.8|
Tamron 28-75mm f/2.8
Sigma 10-20mm f/4-5.6
|price paid:||230CAD (Used)|
|positive:||-Build quality is exactly like the other ATX Pro lenses, heavy, metal mount and alloy body.|
-Constant f/2.8 aperture
-77mm thread like most pro/full frame lenses so you can use your old filters etc.
-Comparatively low distortion
|negative:||-Back focuses quite a bit, had to do a -5 micro adjust for the lens to get more accurate focus. Problem is even after adjustment my copy isn't as sharp as the 28-70mm, but then again the 28-70 is notoriously razor sharp.|
|comment:||Upgraded to a full-frame so I sold my Sigma 10-20mm, which was incredibly sharp and amazing wide angle range. The Sony/Minolta 17-35s constant 2.8 are in the 1k range, but found this little gem and had to act on it.|
Shooting with the Sigma 10-20 my biggest and only real complaint is the variable aperture. When you're shooting in light situations that aren't perfect, the 2.8 is not only going to help but it makes sure you get your exposure no matter the focal distance.
The build quality I already know of from having the Tokina 28-70, so I thought it'd be a great addition as a FF lens to my kit. I'm slightly disappointed that it's not tack sharp at 2.8 like the 28-70mm is, but what's bad is if I micro-adjust the 20-35 and save that profile in my a99; the camera reads the 28-70 as the same lens and makes the same adjustments. So if I'm switching between the two lenses I have to always remember to change the micro adjust again. Bit of a pain, especially since there's no remedy for it, but overall I'm still super happy with the lens.
You can't find a constant 2.8 full frame Wide-angle zoom for under $1000, even Tokina's 11-16mm 2.8 for cropped sensors is in the $700 range.
If you can find one of these I think you'll be happy with it.
