Speedbooster for EF-M mount announced

One thing that snuck through Photokina without much fanfare was that Viltrox, as we reported a few months ago, showed off their speed booster for the EF-M mount.  Available later this month, for a price of around $180 USD, this will allow you to use your EF lenses at approximately their native focal length.  For instance, a 50mm lens will act like a 50mm field of view on an EF-M camera, instead of being a 1.6x crop of a 50mm field of view.

This is their Japanese webpage on the speed booster, loosely translated here is what they have to say about it.  Their site seems down today (Thursday) but we're sure it will be up soon.

Here are some details on the adapter;


  EF-EOS M2 adapter mount
