I wonder if it would be possible to attach Contax G lenses on the M4/3 camera?
Any opinions on that?
Yes, it is possible, you'll find a number of links and discussion of the different adapters at the Getdpi forum (see the link given in the other post).
I own both Contax G (45mm and 90mm, the wa can't be mounted even with the adapter) and Leica M lenses (35mm, 50mm, 90mm). At first I wasn't interested in getting a Contax G adapter, because they are only duplicating focal lengths I do already have with the M lenses.
Here is what I found out :
1) The M lenses I own are one stop faster, F1.4 and F2, than the Zeiss lenses, F2 and F2.8. For this reason, the M lenses are much more heavier, especially the 90mm. So the photo bag is much ligther with the Zeiss G lenses.
2) The Contax G lenses are much more difficult to focuse. I got the Kipon adapter (generation 2, with a bigger wheel, but not the third genration coming with a ring), which is of a rather good quality. With the bigger wheel, you don't have to turn the wheel too long in order to change the plane of focus. However at relatively far distance, added to some rough point you encounter while turning the wheel, fine tuning the focus becomes a problem.
3) Since the Contax G lenses were AF lenses, you don't have a focus ring with marks. This makes zone focusing much more difficult, since you don't have points of reference. It doens't make zone focusing impossible (you can still focuse at a chosen point and if you stop down, you know that you get wider DOF, you can even use a DOF table you can download from the web. l
4) All this makes the Leica lenses easier to focus, both for fine focusing and for zone focusing (although theDOF marks standing in front of the aperture ring will be wrong (DOF tables are not the same for MFT and 35mm format), but you can look at them once and know how much you have to add.
5) When it comes to the performance of the lenses, they are pretty similar in sharpness (it is probably for a good reason that the Contax G lenses were said to be the poorman's Leica lenses). The only difference I have noted concerns the out of focus areas : the Contax G lenses have a more busy less pleasing bokey; the Leica lenses have a softer bokey, but on MFT bodies, as soon as you close the aperture, they look pretty similar; I think that on film the difference was greater; there was something more special to the Leica lenses which I'm not able to describe in words; it had something to do with the way the light was flooding the picture.
