I've tried several different and generally known to be good performing lenses adapted to the E-1 and L1 ... here's my summary: Pentax Fish-Eye-Takumar 17/4 - works well, a bit of flare to deal with Pentax DA21/3.2 Limited - difficult to work with, difficult to focus, mediocre to good results, no fringing Nikkor 20/3.5 AI - excellent to work with, excellent results all around Olympus OM 28mm f/3.5 - okay/okay, some fringing Pentax FA43/1.9 Limited - good to work with but results not as good as Olympus 35 Macro Pentax M50/1.4 - excellent to work with, okay to good results (14-50 does better) Nikkor 105/2.5AI - Exc/Exc, some fringing Nikkor 180/2.8AI - Exc/Exc From what I've seen given people using Leica M-bayonet lenses from Leica and Cosina/Voigtländer with the R-D1, the results have been quite good overall. But again you can only really judge critically on a lens by lens basis. An R-D1 with a Nokton 28/1.9 and a Nokton 40/1.4, maybe the 15mm lens as well, would be a great kit for me FoV- handling wise, and the R-D1 has a wonderful "classic" feel to it. FWIW, I've given up on the 'adapted lenses' business now. All the Olympus ZD and Panasonic/Leica FourThirds lenses outperform all the adapted lens I've used on these bodies.
