Am looking to fill the gap between my wide angle and my long telephoto so have scoped out a very clean manual Sigma 28-70mm f/2.8 and the same condition manual Sigma 35-70mm f/2.8. Anyone had any experience with either of these oldies?
Also looking at a Quantaray 28-90mm with green lettering. There are rumors that Quantarays were manufactured for Ritz Camera, some by Sigma, others by Tamron, and that you can discern which is which by the filter size. Doesn't matter to me so much as I'm a hobbyist, but I would like to know anyone's thoughts on this particular Quantaray, too.
I use a Pentax ME Super.
Thanks.
