So, after pulling out my Sigma DG DN 45/2.8 for the first time in a while, I decided to comparison-shoot it against my well-liked Konica Hexanon 40/1.8 to see how well the adapted lens did. Both shot at f/8 on my Sigma fp.

The Sigma had a shorter close-focusing distance than the Hexanon. But I had a lot of trouble with the autofocus on the fp, getting it to lock on to the particular flower I wanted; and even when it claimed to lock on, it didn't always focus right. It did do a bit better up closer:

The Sigma did much better on this one. It also has a more yellow cast than the Hexanon. And despite them both being set to f/8, with the fp on Aperture priority, the fp consistently gave the Sigma a little more exposure/slower shutter than the Hexanon.

I actually had better luck shooting this bumblebee with the Hexanon, despite the manual focus; the Sigma was never able to nail focus.
