Panasonic G3 Voigtlander 35mm f/1.2 Nokton
Some samples at f/1.2.
The following are samples at f/8. These are jpgs. straight out of the camera. To view full-size high resolution file, click on the image through to flickr > Actions > View all sizes > Original
Below is a test at ISO 100, showing the different apertures. As usual this is tripod mounted and all of the images are processed in Adobe Camera Raw using the default settings. Large high-resolution version available by clicking on image > flickr > Actions > View all sizes > Original.
Once again the images are very sharp, though they don't look as sharp to me as those from the Sony NEX-5n. There is also a slight magenta cast on the images.
I'm unsure as to how useful this lens is on m4/3. There are some good fast alternatives available, and I don't see this lens as being any improvement on the Panasonic 25mm f/1.4. On the NEX it fills in a gap, and works as a "standard lens". On m4/3 it becomes a 70mm f/1.2 35mm / FF equivalent, and that isn't particularly something I would use a lot.
I haven't tried it on my Olympus E-P3 because of the problems of using manual focus lenses on that camera. It is very fiddly, opening the lens up, enlarging a section of the image, focusing and then returning it to the whole frame, and re-selecting the aperture. The G3 is easier in this regard, but again the NEX-5n is so good for this that any other camera suffers by comparison.
So I can't really see myself using the 35mm f/1.2 on m4/3 much, aside from video use, when it could be very useful indeed, and easier to use.
