This week I got my hands on the Speed Booster by Meta Bones. The production company I am shooting for switched out the lens package for the Sony FS700 and went with the Canon EF mount lenses. Previously we had used a Nikon lens adapter. It is really a pretty cool adaptor for use with mirror-less cameras. I had heard about them but had only Canon or PL mount cameras so no real need for them. The white paper published on the Meta Bones site is pretty interesting and a very clear explanation of how it works. Through optical design and physics the device actually makes your full frame lens faster and wider. It is called a focal reducer. Basically the doubler or teleconverter in reverse. This is great on a mirror-less camera. The only downside is if you want to have your telephoto you have to get an even longer lens. With the abundance of new cameras coming out this might be something to add to the gear list.
