Depends on how you define "much" success. I have done "OK" with a 90mm Elmarit and even a 75mm Summilux, as well as a J-9 and a Nikkor 85/2, on my R-D1 - despite the theoretical limitations of its short EBL. By "OK" I only mean more in-focus frames than out. I just have to shoot more frames and use the delete buttons a little more with these lenses.
