Update: Conurus has been kind enough to inform me that the firmware I was using for this review is out of date, and that a newer firmware fixes the IS issue I had.
Here's a quick review of the Metabones EOS to E Mount adapter for NEX cameras—specifically the FS100.
The first thing I noticed was how solid and substantial it felt. You can see the connectors that interface with each electronic mount, there's some sort of I/O for firmware use, and a depth of field preview button.
The release trigger is easy to use, unlike my fotodiox adapter.
The build quality is exceptional (especially for the price).
Here's a list of lenses that I tested, and all worked:
-Canon 50mm 1.4
-Canon 100mm 2.8 Macro
-Canon 70-200mm 2.8 IS II (IS worked)
-Canon 28-135 stock 7D lens (IS worked)
-Tokina 11-16mm 2.8
An issue I've found is that sometimes switching lenses causes the adapter to not recognize the lens at first. After detaching completely (so the contacts aren't meeting) and resetting the lens, it can be controlled.
F-stops are shown on the display. It now feels like my EF lenses and the FS100 are finally a complete camera system.
To conclude, this adapter may seem high in price, but it's the only one in it's class at the moment, and considering what other companies were asking for a higher price with less features, this pricepoint seems perfectly acceptable.
