You Could Have Faster, Wider, & Sharper Canon Lenses By August with New Micro 4/3 Speed Booster
This is good news for all of you who've got Panasonic cameras like the GH2 and GH3, or you've been looking at the Blackmagic Pocket Cinema Camera. If you haven't heard of the Metabones Speed Booster, well it's darn near close to magic with its capabilities, but its principles have been used in lens design for quite some time. This adapter makes lenses faster, wider, and sharper by using lenses made for a larger sensor (like full-frame or APS-C) and shrinking down their output (which is similar to bringing a projector closer to a wall). Check out a review of the original for Sony cameras:
Here is the news from 4/3 Rumors:
Dicahub reports that the EF-M43 Speed Booster will be released in August. EF-M43 will have electronic contacts. This is good news because MFT will get access to the largest lens range of the world. Now Canon gear owners can use their Full Frame lenses on MFT cameras gaining 1 stop of speed!
Check out the lens coverage to understand exactly what's going on:
While there are already Speed Boosters for almost every major lens out there for both NEX and MFT, including Nikon, it was unclear if Metabones was going to be able to work out the electronics for Canon lenses to MFT anytime soon. The big breakthrough for this particular development is that the Canon lenses should now be able to be controlled by the camera with the MFT mount. We'll have to wait and see if this turns out to be true, but if you've been disappointed by the lack of Canon lens support with MFT cameras, you might have a fantastic solution very soon.
