It seems kind of cheap. I am not sure what DG means. I was bidding for one on ebay that was exactly like this but didn't say DG and it was AF which I know is autofocus. I can't see anywhere on this one for target that it says AF which I really want...any help?

One day I will be able to help all the new people after all the questions I ask ;-)

No.

The APO version of the Sigma 70-300 is better and Sigma's lenses seem to be stripping their autofocus gears when connected to Sony dSLRs.

If you're looking for something in that range, the Tamron 70-300 Di LD goes for $160 at adorama.com. It's probably the best of its kind in that price range.

I have a guy that will sale me a Minolta lens 1.5m/4.9ft Macro / 4.5 - 5.6 for $100. Is that a good lens/price?

There were four different versions of the Minolta 75-300mm f/4.5-5.6. All had a minimum focusing distance of 1.5m. The last is identical to Sony's current SAL75300, which sells (?) for $230 alone, or $200 as part of an A200 kit.

I've tried two of them. One I purchase used for ~$125 (a "New"), which I returned. The other I also purchased used for ~$150 (a "D", identical to the current Sony version) which I tried for a while, and eventually sold on eBay for about what I paid. I was not satisfied with th eimage quality from either of them.

Of the lenses your guy could possibly be talking about, only the original (the "Big Beercan") would I say might be worth $100 (and probably more.) None, except the Big Beercan are as good as the Tamron 70-300 Di LD, and it is unlikely that someone would part with a Big Beercan for $100; they go for $200+ on eBay. The other three, plus the Sony, are all optically identical, which is to say that they are soft throughout their range, and have considerable chromatic aberration past 200mm. [See http://www.slrgear.com/reviews/showp...uct/986/cat/83]

For the absolute best quality telephoto zoom lens on a budget, the Minolta 70-210mm f/4"Beercan" is the best choice, despite the recent phenomenon of $200+ prices on eBay. It is tack sharp throughout its zoom range, and has a constant aperture of f/4.0. If you need something longer, the Tamron 70-300 Di LD is good. If you can get a Big Beercan or a Minolta 100-300 f/4.5-5.6APO ("D" or not), those would also be good choices. Any other Minolta or Sony 75-300 or Minolta 100-300 (non-APO) would be a last resort if you got it really cheap. (I've seen the non-APO 100-300 go for ~$70 on eBay. That would be a good deal.)
