Sharpness at 70mm

For these tests, the Olympus M.ZUIKO Digital 40-150mm f/4-5.6 ED lens was attached to an Olympus E-P2 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 70mm

Centre sharpness is high wide open, and peaks at f/8. Again, contrast isn't the greatest - meaning you will likely want to apply some sharpening to bring out all the detail resolved by the lens.

The edges are sharpest in the f/5.6-f/11 range, with the sweet spot being f/8, just like in the centre.
