Hi !

I tested this lens on my Olympus E-420 (photo "Camellia") and then with my Olympus E-620 on a tripod at about 2m of a road map.

I let the camera determine the shutter speed and I took a serie of photos from full aperture (f/1.7) up to f/4.0 to compare the sharpness.

I think at f/1.7 we can say that this is good enough ; at f/2.0 better, at f/2.8 very good. At f/4.0 the sharpness seems excellent and doesn't change a lot when closing more.

What do you think about ?
