Hi again... Are you sure the 1.6m distance is ok with this lens? The closest focus distance is shown as 1.8m (1.5m at macro setting) on Nikon' s site . However, In fact this does not explain the issue. The previous samples were in focus but soft (as in very low contrast). Maybe the results are because of the sum of more than one issues (distance, aberrations, curvature etc...)

Yes, 1.5m-1.8m is marked as macro distance (but there is no macro button), 1.8m-infinity is marked as macro distance. The lens has no problem from 3m to infinity, including the [email protected]. With my test, only in the distance range 1.5m-2.5m the lens is extremely soft at 200mm (indeed 150-200mm) and f2.8, the results in 80-150mm and f2.8 are indeed very good (indeed very sharp to my eyes). I heard the lens is soft at 200mm and f2.8 and close distance, but I didn't know it is so soft--which makes me wonder if this is normal for this lens or the lens is defected. If it is not defected, I want to understand what cause the pattern of the softness (clear letters imbedded in blurry halos): normal spherical abberation, reflection of the sensor, or something else?

 

Thanks,

Frank
