  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

WANTED: Arri MFF-2 Follow Focus

Take a look at the o'connor Ofocus. I just bought one and it's fantastic.

Yeah, it looks pretty nice. What kind of lenses are you using with it? I'm using Nikon lenses and I'm afraid the gear box on the O Focus mini is going to hit the body of the Epic.
 
I just used it with the zeiss cp.2s and rpz 17-50 today on a commercial (got it yesterday) but I dont think that you will have any issues using it on an epic with nikons. The gear can work on either side of the gearbox.
 
I've been considering the MFF-1 or MFF-2 for Nikons as well, but don't they have 1:2 ratio. I fear that will be problematic with Nikons.

The MFF-2 is available with two different gear ratios. MFF-2 Cine has a gear ratio of 1:2 dedicated to the cine lenses and MFF-2 HD with a gear ratio of 1:1 is dedicated for still photo as well as ENG broadcast lenses.
Sometimes camera operators who are pulling focus by their own also prefer the Cine version on still photo and ENG broadcast lenses because the length of the focus pull is not as long as with the HD version and therefore its easier to pull focus while operating the camera.

Philip, I like that the MFF-2 has a 1:1 gear ratio for still lenses, but it would be great if it were 1 to .75 or less. Keeping it at 1:1 does not help with the already intrinsic problem with still lenses: they are already hard to focus. If the ratio was .75 or less, then I'd think it would help to spread out the focus marks at greater distances, especially anything past 15 feet. Past 15 feet is where all those focus marks on a FF disk are too close to each other to distinguish. At .75 or less the focus marks become spread out from each other and become easier to hit while focusing.

Anyways, I'm not an engineer. This is just my 2 cents. I love the construction of the MFF-2 over other similar models. But I just wish the gear ratio was better suited for still lenses.
