Szymon Starczewski has just posted a full review of the new released Olympus M.Zuiko Digital ED 12-100mm F4.0 IS Pro lens (Amazon/ B&H/ Adorama/ eBay) at the LensTip.com. He tested the new lens on the Olympus E-M5 Mark II and found many pros: solid, weather-sealed casing, excellent image quality in the frame centre, good image quality on the edge of the frame already up from the maximum relative aperture at every focal length, lack of spherical aberration problems, moderate longitudinal chromatic aberration, low coma, slight astigmatism, silent, flash-quick and accurate autofocus.

Conclusion from LensTip, “…You get a lens with a very wide range of focal lengths, a decent constant aperture fastness, one able to provide good quality images at every combination of aperture and focal length; additionally its autofocus is efficient and its optical stabilization performs very well indeed…”
