I did additional test shots today against an old brick wall gate. I can conclude that the 35-90mm is sharper than the 50-110mm at the lower focal length-- 50mm with the exception of the corners (H3DII-31). At 80 and 90mm, the difference in sharpness is very marginal and I could not honestly saw there was a noticeable difference except at the corners where the 50-110 was a bit better albeit the difference in the corners was much less noticeable than what I observed at 50mm. This pretty much held true at all focal lengths I examined. So far that was 4.5-8. I have not carefully looked at the f11, 16 images.
I would really be curious as to results of others and if anyone has taken shots with the H3DII-39, 50 or 60. Mark
just did a few tests against my 50-110mm
The 35-90 beats the 50-110mm at 50mm hands down
at 70mm, they're about equal and at 90mm the 50-110mm performs better.
The extreme corners are weaker overall in the 35-90mm. Looks like I'll have to zoom out about 2mm each time to compensate for that.
All my RAWs were converted in ACR, so no distortion correction was performed. Perhaps the correct in Phocus will help the files quite abit
Overall this lens is a beauty to handle, and it makes the camera feel well balanced.
Autofocus is snappier also.
