> It's says 'Tokina SD 70-210mm 1:4-5.6 Japan It's a very compact 70-210 zoom, manual focus only (as far as I know, at least the one I'm referring to is manual only). It's supposedly a decent enough zoom, although the larger Tokina 70-210/3.5 (optically identical to the more common second-generation Vivitar Series 1 70-210/4) and the even larger Tokina AT-X 80-200/2.8 are likely to be better lenses (I've never used the SD 70-210/4-5.6 to compare it with the others, so I'm not certain of that). There's also been (I think) a Tokina 70-210/4, too...
> aperture ring 4 -32 Of course, it's f/4 only at 70mm - its maximum aperture value "creeps" upward, reaching f/5.6 at 210mm. The Tokina 70-210/4-5.6 is quite a common lens on eBay nowadays. Hmmm... I wonder how it compares to the much discussed Pentax F 70-210/4-5.6. I assume that the SMC on the Pentax lens is a better set of coatings, but I wonder how they compare otherwise... Fred
