The Sigma Zoom-Gamma 21-35mm f/3.5-4 is quite a remarkable lens, with good image quality and a zoom range that is hard to replicate or replace. The lens was launched by Sigma in 1979 as the world's first wide-angle zoom lens.

The lens is a solid all-metal and glass construction, with 12 elements in 12 groups, 105mm in length, weighs 450 grams, comes with a non-rotating front element, takes 67mm filters, and has a built-in floral pattern hood.

I also did an earlier post with the lens mounted on the digital Pen E-P5, which includes images shot at various focal range equivalents, but felt that the equation is not complete without a similar post with the lens mounted on what it was originally designed and produced for, an SLR film camera.

This session here was down at the park, on a hazy day, with shots mainly of the landscape. The images, as you can see, turned out to be sharp, clear, and better than expected. They were shot on a roll of expired Fujifilm Superia 200, post-processed on Olympus Viewer 3 (OV3), and print-sharpened on Google NIK Sharpener Pro3.
