200mm, F 36. Photo taken several days later, the first one was blurry due to shake. This one suffers a bit from colour cast and also diffraction.

200mm, closest focus 
is only 25cm from outermost edge of the lens, F 8. Focus on the program wheel of the camera.

The lens was adapted via an adapter with contacts. Pay attention, both, the Fotga and the Commlite adapter automatically set the camera to APS-C, although it's a full frame lens. So you have to correct this via the camera menu. Aperture is controlled by the camera, I focussed manually. Autofocus is possible, but not always reliable and it's very slow.

Seen the prices of Sony full frame lenses, this is an inexpensive all-purpose alternative if you don't need autofocus. Wide open it's a bit soft at the edges and there are shades on the upper edges at 28mm, otherwise image quality is just fine. There is colour cast at the tele end, as with most long zoom lenses. It has very good close focus capability.

At F 29 it only gets a bit blurred due to diffraction, at F 36 (200mm) diffraction is quite visible. This is a problem of the sensor size, not the lens (see APS-C comparison page for an explanation).
