IBC 2011: MTF EF-mount, aperture control on F3 and Fs100

by Sebastian WöberSeptember 18^th, 2011

The problem when using Canon glass on a camera like the Sony F3 or FS100 is that you cannot control aperture unless you have a mount that accesses the lenses aperture control.

If you switch(ed) from Canon hdslr to one of the new large sensor cameras this mount makes it possible to take your EF lenses along.

MTF has produced some other mounts like the Nikon G to Sony F3 mount or a PL to Sony E that I’ve heard are of very good quality.

The MTF adaptor will allow you to use Canon glass on the Sony F3, FS100 and Panasonic AF100 cameras and control aperture electronically in 1/8th increments. It’s precise and will also show you your exact focal length. You buy the control box and you can upgrade with future adapters for different cameras.

We’ve heard about the similar Birger mount at NAB, but so far they haven’t been able to deliver. MTF is expecting to start shipping “in a couple of months”. Mike doesn’t know about pricing yet, but said it would be below 1150€ / $1600.

I can imagine this thing will be more affordable if more peopl buy it so if you’re interested you should contact these guys at MTF: their website.
