Will the SLR magic anamorphot work on my GH3 with a voightlander 17,55 without vignetting?

Most probably not. According to their manual, 20mm is the widest you can go on m43 cameras. Unfortunately I don't have anything that is accurate enough in that range to categorically answer your question. I do know that 20mm on a GH2 does not vignette. The GH2 and GH3 have different sensor sizes but I can't get my head around whether that would help the GH3 with it's narrower sensor or not. Perhaps someone else can figure that out.

If you are absolutely set on using one, you could crop the vignette out in your NLE but you'd begin to loose resolution.
 
yeah, i already saw a black magic pocket with a 17,5 that didnt vignette but then again the crop is 3X. and the GH3 is 2X. yeah cropping out in post is not something I plan to be doing in the future.
 
Here are two stills from a video I just took on the GH2. The first one is the 14mm pancake and as you can see, it vignettes pretty bad. The 2nd is with the 20mm pancake and there is a very slight vignette. When i was using the 14mm on my BMPCC, I could use the adapter with the 14mm and no vignette, but that is 2.88x crop. Unfortunately, I do not have a zoom lens wide enough to test 17.5mm, but it would be very very close on the GH3. I believe the GH3 is more of a true 2x crop when the GH2 is a 1.86x crop. Given the difference in focal length from 14mm to 17.5mm and the additional crop, it may have a very slight vignette. Sorry I cannot get you an exact answer, but this should be a helpful guide...14mm.jpg20mm.jpg
