I've been using a Voigtlander Ultron 28mm f/1.9 (M39) on my E-P2 for a couple of months now, and have been more than happy (in fact, dumbstruck sometimes) with the image quality I can achieve ... but there is a downside: I find the image in the viewfinder (EVF) dim, and hard for me to bring to sharp focus accurately.
I also have a number of Konica Hexanon AR lenses (40mm, 50mm & 57mm). By contrast, the images in the viewfinder are sharp and bright and easy to bring to sharp focus.
There are two significant differences that I am thinking about:
1. The FL of the Ultron is 28mm, and I have read many suggestions that using adapted lenses with a FL of less than 35mm on :43: bodies can be problematic -- is this one of the problems?
2. The distance between the rearmost element of the Ultron and the sensor is much smaller than the distance between the rearmost element of the Hexanons and the sensor.
Then today I happened upon a thread with this comment

Interesting ...a used Leica 28mm/2.8 Elmarit ... The GF-1 w/ a Leica M Lens is definitely a compromise, focusing is not always clear and takes some getting used to -- using the EVF I need to employ the MF assist a lot
