I'm very happy with the performance of the Pentax lens. I don't know
anything about the Sigma.

I've been looking for zoom lenses made specifically for the new Pentax
digital cameras, and found these two similar lenses:
Pentax smc P-DA 50-200mm F4-5.6 ED
Sigma 55-200mm F4-5.6 DC
The Sigma lens is definitely the more affordable of the two. Is the
image quality actually noticeably less than the Pentax lens? Does
anyone know the advantages or disadvantages of each lens? Is there
another brand to consider, which covers this same range of focal
lengths?
thanks,
Glen
