Needing a bit of free help with zoom lens (or lenses) for the EM5. Wanting sharp images. I have tried both Oly and Pany longer zooms (14-140 and close) and did not care much for the sharpness at all. A couple of them can be quite sharp at mid length, but I am wanting more. I understand that a $500 lens might not do what I want. I can learn to save ..... Any suggestions for good sharp zooms (2) for short and long reach?
