I'm not sure whether they are similar. I have the manual focus Cosina 19-35mm that I got direct from the Cosina factory new. While the specifications appear to be similar to the Tokina, I have discovered some differences.
A search on the net has the Tokina having 6 aperture blades. My Cosina has 8 blades. The Tokina's front barrel doesn't turn when focused (internal focusing?) whereas my Cosina does. Weight wise, the Tokina is a tad heavier.
Please note that the 2 lenses were made in manual focus and auto focus versions, so there might be some redesign of the lens barrels.
I find the lens to be pretty sharp and flare hasn't been a problem. About the only issue with the lens is the big 77mm filter diameter which can be expensive. The focal length range is kinda limited compared to other newer zoom lenses. Other than that, I find the lens is very good value for money. Definitely underrated performance wise.
