This is just amazing! The size is very similar to a can of soda (without the lens hood attached, still very similar if reversed for carrying around) and has a 70-200mm equivalent field of view. It works really well and is very responsive.

Very good material, but the lens is better... Is very clear the photos are really amazing. It was a very good quality/price buy.

Excellent quality, both optically and build. Small fraction of the size and weight of the equivalent for a full frame camera. There is no current competative product at this quality, size & weight.

Handling and features Covering angles of view equivalent to the popular 70-200mm range on a 35mm camera, this lens boasts a constant fast f/2.8 maximum aperture, internal focusing and zoom, optical stabilisation and a nano surface lens coating to help suppress the effects of flare.

Sharp edge to edge at any focal length, very fast autofocus, excellent contrast and colors, small and light-weight. The lens has internal focus and zoom (not change its size). I use the lens on Olympus OMD E-M1 and the results is real profesional.
