In news sure to please owners of Canon lenses and Panasonic GH4 cameras, Metabones has at long last released its solution for attaching Canon EF glass and other EF mount lenses to micro four thirds (MFT) cameras. And the bigger news is that not just one but two adapters are now available – an EF-to-MFT Smart Adapter and an EF-to-MFT Speed Booster.
Many moviemakers rely on a range of cameras and lens mount sizes to handle a range of projects and ways of shooting. Informal surveys of independent moviemakers indicate that the most popular glass is Canon’s EF range. Other brands using the EF mount include LensBaby, Samyang, Sigma, Tamron, Tokina and Zeiss.
Canon optics can be bought pretty much anywhere and are staples at movie rental houses. Some vintage lenses such as Nikon’s Nikkor F-mount series can be modified to fit onto Canon EF mounts. The popularity of the 4K-recording Panasonic GH4 amongst moviemakers has now created something of a dilemma – do you invest in a whole new set of lenses that are MFT-only or do you look for a way to adapt the existing EF-mount glass that you know and love so well?
Metabones has the Solution
Metabones has aided that decision with two solutions that make the most of key features in Canon’s current lens line-up – lens stabilization, electronic manual focusing and aperture setting by the camera body. Just one caveat – neither adapter supports autofocus so you will need to focus manually. That should not be too much of an imposition given most videographers rely on focusing by hand anyway.
The Canon EF Lens to Micro Four Thirds Speed Booster has the added advantage of increasing your Canon lenses’ maximum aperture by one stop and making your lens 0.71 times wider. For example, attaching the Speed Booster to the Canon EF 24-105mm f/4 L IS USM kit lens effectively converts its maximum aperture into f/2.8 and widest focal length to 17mm.
