Sharpness Cont... 3
Sharpness at 300mm
For these tests, the Olympus M.ZUIKO Digital 75-300mm f/4.8-6.7 ED lens was attached to an Olympus E-PL2 body, which in turn was mounted on a sturdy tripod. The self-timer was activated. The 100% crops represent about 1/300th of the total frame area.
The full frame at 300mm
Centre sharpness is good wide open, very good at f/8 and f/11, good again at f/16, and predictably poor at f/22.
The decentering issue isn't nearly as pronounced as at the 150mm setting. Neither the left nor the right edge is very sharp at f/6.7 or f/8, but while details on the left edge of the frame become tack sharp at f/11 and f/16, sharpness on the right edge – where the edge crops are from – is still merely good, but not excellent at these settings.
