Our reader Brian sent us this mail to warn about a possible issue with the new Metabones Canon EF adapter:
“FedEx delivered today the Metabones Canon EF to Micro Four Thirds Speed Booster, P/N MB_SPEF-m43-BM1, that I had ordered after reading your posting as to its availability. I have test fit the adapter to all MFT cameras I own, and I wanted to alert you to the fact that it DOES NOT FIT the Olympus OM-D E-M1 camera. It’s not even close. The adapter interferes with the forward projecting EVF hood on the E-M1. The adapter also does not fit the Olympus E-M5, although the interference is not as severe. The adapter will fit the Olympus E-M10, although the adapter remains in contact with the EVF hood. I don’t know yet if this tension prevents the lens flange from seating flat. If so, this could cause lens decentering.
The adapter does fit fine on Olympus PEN Mini E-PM2, and Panasonic Lumix models G5, G6, GX1, & GF5. I mounted a Canon EF-S compatible Tamron SP AF17-50mm f/2.8 XR LD Asperical (IF) zoom lens on the adapter, and made some test shots with the E-PM2 camera. Result is a 12-35mm f/2.0 zoom lens. Sweet! This Tamron version lacks IS, but that isn’t a problem on Olympus bodies.
I am a bit surprised that Metabones did not engineer the adapter to fit more camera models, especially the popular E-M5 and E-M1.“
Hope Metabones will release a statement about this soon!
