Tokina 300mm f/6.3 MF Macro Reflex
(From Tokina lens literature) The New Tokina 300mm f/6.3 compact telephoto mirror lens is designed specifically for mirrorless compact cameras using the micro 4/3rds mount.
The 300mm focal length of the lens gives effective 600mm (in 35mm terms) when placed on a mirrorless camera body making it a super-telephoto lens. This allows distant subject to be brought in much closer. But despite this powerful focal length the lens is incredibly compact to match the size of the compact cameras it was intended to be used with.
The lens has a fixed f/6.3 aperture.
The Tokina 300 has all metal lens barrels and very high quality glass optics to yield the best optical performance from a new of this design.
This lens has a wide grip area on the manual focusing ring and smooth movement to assist in focusing. This is not an auto-focus lens.

I purchased this lens to utilize on my OMD EM5; I'd say from the OMD this lens wouldn't be very helpful with no stabilization. The picture created through this lens isn't that amazing, so I'd not use it for any serious shots. But because it is so streamlined and functions nicely with the OMD, It is not difficult to transport around and have fun with it. Example 1, Example 2reviewed March 8th, 2015 (purchased for $149)
