Here, brothers, is the Sigma 35mm f1.4 on the Pentax K1. I compared this lens to the Pentax 31mm f1.8 and, while bigger and heavier, I decided to keep this Sigma.

Sigma EX 105mm f/2.8 macro. I needed to play around a little with the AF fine-tuning (maybe still needs a little more) but the image quality so far seems to be outstanding.

A couple of quick test shots with this new-to-me lens, both wide open and hand-held.

The dragonfly shot is excellent.

I agree, and I'm not a fan of bug shots but getting the focus spot-on for a shot like this must have been tough (or very, very lucky).

Here are a couple of surfing shots from the EX 105mm f/2.8 macro, the longest lens I had with me. I've cropped them quite a bit and did some PP in Snapseed.
