"Just noticed this article on Extremetech. Some smart guy created an application employing some of the latest techniques in de-convolution blur correction and it's open-source!

Here is the developer's site and the downloads site

NOPE... I haven't tried it yet so I have no idea how well this will work when applied to subtle blurring in large imagery like we have around here. I figured some of you would find this interesting anyhow."

Not Full AF on any lens.
The adapter AF does not function fully between the minimum focus distance and infinity. You have to manually focus to the vicinity of the target, and then let the adapter AF take over.
I also have the Sigma 150-500. But I often take the DA*300 and the 1.7x instead if I'm going to be carrying for any distance.

I should know, but does this work with SDM lenses?

This is more than a converter. It is an adapter which will also autofocus even manual lenses
