Guy, you may be right here - seems from the 50 on up, all is fine...Seems the wider the lens the worse the issue
Hi Brian, I take that back. I'm sorry to cause more confusion here... Took another good look at the test I did with the 90 Cron, and cannot be sure it's not motion blur I'm seeing with the shots I took with the 90mm. Unfortunately I can't perform more tests since my adapter is back to the homeland for the second time.Interesting that there's a problem with your 90 Cron...
Hi Robert, good to see you hereWe saw the same thing comparing the RD1 to the M8. Lenses that were crap on the RD-1 actually looked good on the M8.

Robert micro lenses are only used to gather light in the corners and are not to increase or fix any sharpness issues in the corners. They just angle the light to illuminate the frame. Leica engineers will tell you the same thing. It does not fix any lens issues with regard to sharpness. Leica lenses do not have sharpness issue with a film Leica and will not with a crop M8 either it is to gather light.Guy:
It is the same problem I mentioned in the MFDB thread. The Leica M8 has angled micro lenses to correct the problems with the wides and the edges of the frame, the G1 doesn't.

Yes, but they're still lenses, which means they're part of the total optical system. While I don't believe they're used to "fix" sharpness issues, it seems to me that they certainly could induce sharpness issues if they're poorly matched to the characteristics of the main camera lens.micro lenses are only used to gather light in the corners and are not to increase or fix any sharpness issues in the corners.
I agree, however, knowing that the wider ones will give me much more corner trouble than telephoto ones (with my lenses anyway), will save me from some disappointment down the road. Course' I'm not using a G1 for landscape or architectural work either. Horses for courses....My interpretation is that for people who buy a G1 as a way of experimenting with the "looks" of a lot of different lenses, this difference in optimization simply will be another opportunity for interesting discoveries. For people who buy a G1 thinking it will serve as a budget M8 substitute, though, it's likely to produce some disappointments.
While any single lens will give a more unsharp image if the light rays are at an angle with the optical axis, I can´t believe any such shortcoming of the microlenses would show up as unsharpness in the final image.Yes, but they're still lenses, which means they're part of the total optical system.

Thinks you are right; see here:I agree, however, knowing that the wider ones will give me much more corner trouble than telephoto ones ......
