Officially announced - Metabones Canon EF Speed Booster for Micro Four Thirds and Panasonic GH4
September 18, 2014
Some lenses "show" the bigger aperture with the Speedbooster some dont
Sigma 35mm F/1.4 Shows F/1.4
Canon 50mm F/1.4 shows F/1.4
Canon 40mm F/2.8 shows F/2.0
Canon 16-35 F/2.8 Mk2 shows F/2.0
Canon 70-200mm F/2.8 shows F/2.0
Tokina 11-16mm F/2.8 shows f/2.0
going to do some tests later today with the sigma 35mm f/1.4 and speedbooster wide open against the SLR magic 25mm M43 mount T0.95 which theortically should be similar apertures
