The Sigma 28-105mm 1:3.8~5.6 UC III Aspherical IF, a follow-up of its predecessors the UC and UC II, is another zoom that I can use on the Pentax MZ-7 that I have. The lens too, came attached to another camera body that I bought online.

The lens, an upgrade of the previous versions, is of a new lightweight design. This includes the use of aspherical optics and new mechanical construction. The internal focusing system and a non-rotating front barrel for convenient filter use of the previous version are, however, retained.

This compact and lightweight lens, with excellent imaging capability and is easy to use, is rated highly by reviewers which I agree with. A bit on the negative is that the lens's focus ring, though fast when used manually, is rather loose and sloppy.

Images were shot on a roll of recently expired Fuji Superia 200, scanned at 2400 bits, and were post-processed on Olympus Viewer 3 (OV3), with final print sharpening on Google NIK Sharpener Pro 3.
