with Heavy Duty Tripod Mount

Use YOUR professional Canon, Fujinon, JVC 1/2" Bayonet (B4) lenses on:

Panasonic GH2 (ETC MODE), GH3 (ETC MODE), GH4 (4K & ETC MODES), BMCC (MFT mount), BMPCC

The tripod bracket has both 1/4" and 3/8" screw mounts, allows use of 1/2" lenses without a complicated rail system.

Notes:

1)

This mount adapter is for 'general'  1/2" B4 lenses, which can be identified by their rear throat size (about 41mm diameter), see my last gallery picture.  Some 1/2" B4 lenses have larger rear throat size (like 47mm), which would not fit this mount adapter.

2)

1/2" lenses do not completely cover the sensor of micro 4/3 camera, so you should do any of the following:
1. You can use 1/2" lens with 2x extender without vignetting on Panasonic GH4 in 4K mode.
2. You can use 1/2" lens in 2x without vignetting on Black Magic Design Cinema Camera and Black Magic Design Pocket Cinema Camera.
3. You can also use 1/2" lenses in 1x without vignetting on Panasonic GH2/GH3/GH4 (enable 1:1 crop mode).
