I've had my grief with Sigma lenses, but at least Sigma makes an

I could really use, that Pentax does not make.
I have several Sigma lenses & the only one that disappointed me was the 50-500.
Hmm odd.
I have had the 100mm macro, and still have the 2.8 70-200mm and the 50-500mm,
the layters version that is with in-lens stabilization and silient focusing.
I found all of them performing pretty good, allthough I must say that I use
the 50-500mm near or at 500mm in almost all shots with it ...
What exactly disappointed you in that one? Image quality?
Regards, JvW
Yes. Image quality is not so good at 500mm.
It's not really that good at 50mm either, but I have other, better
lenses covering the range from 18mm to 300mm (including other Sigma
lenses), so I never really use it for anything except the long end of
the range. I'm willing to accept that mine might be a less than prime
example.
Unless I've forgotten one, I have 5 Sigma lenses & the 50-500 is the
only one that I've been dissatisfied with.
