Sigma/price questions..

Well I'm looking at some used lenses and the prices are kinda confusing.


28-70 3.5/4.5 -- $139

28-80 3.5/4.5 -- $44

28-80 3.5/5.6 -- $54

All are sigma but no descriptions or pics so I can't really tell the difference, but shouldnt the middle one be the most expensive? Anyone used these lenses?

And is $89 good for a sigma 28-105 uc-III 3.8/5.6...better than the smaller ranged ones?

They also have a Pentax FA 28-80 3.5/4.7 for much cheaper than all the other --5.6 models, why would this be?

Sorry for so many questions, thanks!

I can't speak too much to the Sigmas but the Pentax is considered by many to be one of the worst lenses they ever made. Soft at all ranges. I got one in a large lot on Ebay and sold it for $20.00.

The UC zooms may not that great either but I've only had the 70-210 and the build quality was average and so were the pictures. I can't speak to the ones you listed

I have a Sigma 28-82 f3.5/5.6, and it was my favorite lens for the longest time.

I can't say that it's the same as the 28-80 3.5/5.6, but if they are pretty well the same lens I could ensure you some beautiful pictures with it.
