Here it is all together; GF1, Adapter, 12mm Elgeet f/1.2
The first thing I noticed about this lens is that it is quite heavy, in fact it weighs more than the camera body itself, so the whole thing is terribly out of balance. The second this is that doesn't actually cover the chip in the Panasonic, in fact it vignettes like crazy:
1/4000 sec f/1.2 ISO 100
But frankly, I don't really care if my shots are in focus (wait, did he just say that?). Yes, it's true. If all I wanted was sharp photos in the first place, I wouldn't be melding with wacky gear from the 1950's with modern digital, I'd be shooting with the 14-45mm zoom. All I want is for the image to move someone; like a Voigt-Kampff test, I want an emotional response.
Anyway, I kept playing with the lens and finally found its sweet spot:
1/1000 sec f/1.2 ISO 100
If you're going to try this, just look for images where the vignette looks natural, and no one will notice that your lens doesn't cover. Here's another example where it works:
1/30 sec f/1.2 ISO 100
What I'm really going after here is a way to bypass the thinking side of my brain and access the feeling part of it. I used to have it 20 years ago, and somehow I feel I've lost the rawness. Maybe this is one way that will help me find it again.
