So I got my Helios 44M-6 over a week ago and a few days later an M42 adapter. I bought a cheap adapter that does focus to infinity. Not much chance to take pictures with it but I did get out today while walking the dog.
These were shot as JPEG. They are straight from the camera without any post processing. I usually never shoot JPEG but I was testing for sensor dust and forgot to change it back.
All images resized by Picasa 3.

Now with this third image there is considerable blooming and over saturation of the red flower, plus it was handheld. I think my JPG settings must be BRIGHT, or even BRIGHT plus a bump in the saturation level.

There were a few other images but the flare was almost unacceptable on some and the subject rather boring on others. I will try this with RAW a bit later.
