Metabones Speed Booster for Micro Four-thirds

A couple of months ago I wrote about the Fotodiox Light Cannon adapter that promised to adapt legacy lenses to Micro Four-Thirds cameras without a change in magnification and a one stop increase in light. I tried the Light Cannon with my old Nikon F lenses with pretty bad results. I returned it thinking that maybe it’s not possible to do this and still get a good sharp image.

When my local camera store Pro Photo Supply here in Portland called and told me that they had just received the new Metabones Speed Booster I had to give it a try. According to the Metabones website the adapter has a magnification factor of 0.71 and increases the speed of the lens by up to one stop.

The photos in this post show the results of shooing with the Speed Booster on my Panasonic GH3 using a 50mm f/1.4 Nikon lens from 1970. The images were all shot at f/1.4.

I’m not sure I’m ready to spend $429 on the Speed Booster but I have to admit that I really like it.
