So, I tested my lenses. It's really, really bad. My Tokina is absolutely worthless. It may be due to wrong focusing on a digital, but I doubt it. I always have considered this an excellent lens. Befor I bought it I tested it agains my Pentax FA 28-80mm Powerzomm, and found that the Tokina was sharper. In 2001 I wa on an Irish mountain on a stormy day. I fell I smashed my on a rock. It got a little loose, but I managed to tighten some screws inside as well as streighten the boyonet mount, which was slightly bent. I have used it ever since. Without noticing something was wrong.
Now I am wondering if half of my bad film reslults - and half of my bad scanning experiences were really caused by this lens!!!??? Most of the not very sharp pictures/scans I got from my MZ-S!!!???
Hi Jens:
Your Tokina must be damaged indeed. I have this lens, and I also had the F 35-80 4-5.6, until I sold the latter last January, and the Tokina is sharper. In fact, it is very sharp for a zoom lens, its only disadvantages being noticeable barrel distortion at 28 mm. and that it is a flare prone lens, compared to SMC Pentax lenses.
