i'm doing that at dyxum now, but i was hoping for any input because i don't have a lot of time before the auctions are over. i have already ditched the sigma 400 and probably the minolta 500 because of the f8. i'm just looking to have any stricken from the list which you consider not worth looking at.

do you have an opinion on the tokinas? just generally is fine. i don't know anything about them except that my uncle was an avid photographer and he had a couple.

btw, for the price, i may go ahead and get a beercan. i'm keeping an eye on them on ebay.

p.s. thanks for the other two sites.

The Minolta (and the Sony) 500mm f/8.0 Reflex is a catadioptric lens, so it has fewer optical elements and polished surfaces than refractive lenses. That makes it quite sharp. There alsoisn't a lot of refracting going on, so there's very little chromatic aberration. Preventing or correcting chromatic aberration is what makes good long refractive lenses big, heavy and expensive.

And it's the only f/8.0 lens that will autofocus.

The only downside is the goofy bokeh.

So don't discount the Minolta 500/8 Reflex so quickly.

When I was a Sony user I briefly owned a Sigma 400mm f/5.6. I bought it used but returned it because the focus mechanism was prone to jamming. The test shots that I did manage to get with it were not very impressive.

Not on your list is the Tamron 200-500mm. I had one of these and found that it worked well out to about 420mm. After that the sharpness dropped off noticeably.

thanks for the input, frank. i will look at that tamron. i'm kinda avoiding the sigmas, because they do not review as well as minolta lenses or some tamrons.

alternatively, i'm thinking of a 200mm or 300mm f2.8 with a teleconverter.

The Minolta and Sony 200/2.8, 300/2.8, 200/4 and 300/4are very nice lenses, and when mated to a Sony or Minolta teleconverter. The 200/4 and 300/4 won't autofocus with the matched 2X TCs, andthe 200/4 won't autofocus with the matched 1.4X TCs.

I will also say that buying a really good lens with the intention of using it with an inexpensive teleconverter is not a very good idea. You'll get better results from a lesser lens of an appropriate focal length.

Sony (Minolta), Sigma, Kenko, and Tamron sell very good matched teleconverters that work with some of the lenses you've mentioned.
