Unless you might think I’m writing about some new dietary supplement, or a miracle cure for (my) aging bones… The Metabones Speedbooster is a lens adapter with an optical element at its rear end. Ok, I probably lost most of you by now. Ho hum, just another boring gear review. Yup, but to my photog friends and camera buffs, this is one piece of gear you just might find interesting. So, read on! The Metabones Speedbooster adapters are available in several lens mounts, adapting various full-frame lenses to Sony NEX, Panny/Oly Micro 4/3, and Fuji-X cameras. The rear optical element (made by Caldwell Photographic) is a focal reducer, shrinking the full frame image by a factor of 0.71X. This means, the lens’ focal length changes by this factor and the intensity of the reduced image causes an increase in brightness equivalent to one full aperture stop! When you factor in the 1.5x crop of an APS-C sensor, a 100mm f/2.8 full-frame lens will have a field of view equivalent to 106.5mm f/2.0 lens when mounted on an NEX camera by a Speedbooster. Not too shabby huh?
