I recently found a photo I’d taken of my chess set for photography class in 1977 and decided to recreate it using the same set in digital and in color. The assignment was Use Selective Focus. THE ATTACHED PHOTO IS NOT THAT PHOTO! But while I had the set out, dusted off and set up I decided to use it as a project using a variety of lenses I don’t get out very often. This is the shot with the Sigma 8-16 UWA zoom.
It’s hard to achieve much by way of selective focus with the 8-16, although it does focus as close as 240mm.

Yeah, the photo recreation of the assignment was shot with the DFA 50mm f1.4. One can get pretty darn selective with it. But it would go in a different thread

While the winter skies were clear I did some Astrophotography experiments with the Sigma 8-16mm f/4.5~5.6 tonight with a K1. In un-cropped mode, the lens is only really usable at 16mm. Any wider than 16mm and the hood starts showing up in the frame.Though IMO the astigmatism is more problematic.



un-cropped full frame @ 16mm sans optical corrections.


With some artful cropping I was able to diminish the inherent limitations of the lens and produce a passable image.

This lens won a contest - architecture contest

Pity that Sigma stopped making lenses for the K-mount. I have a quite a few keepers from this lens, love it and still use it after a decade; now on K1 in cropped mode.

I hadn’t taken this lens off the shelf in months and decided to take it on my daily dog walk at Champions Park instead of the usual DA* 50-135 or 60-250. This is my bestie’s dog, Ellie.
