I'd be grateful if someone could enlighten me as to the different lens mounts etc that are available.

I always hear different words like B and PL and sometimes i get confused.

What lenses fit which cameras? Are some panavised lenses changed? Please, do tell :blink:

Cheers guys,

Most modern 35mm and Super-16 cameras used a strong bayonet mount called the Arri Positive Lock (PL).

Except for Panavision cameras, which have their own similar mount. I don't know what it's called, but I think it's "PV".

You run across the B4 mount used by 2/3" CCD video cameras.

Besides those, there are older lens mounts and mounts for smaller video cameras, like 1/2" CCD cameras (I think the mount is just called the 1/2" mount.)

Film camera mounts basically have gotten beefier over the years to handle the weight of heavier lenses. For 16mm cameras, you had the tiny threaded screw "C" mount, the Arri Standard mount, then the Arri Bayonet mount, then the Arri PL mount. Eclair cameras had their own Eclair or CA-1 bayonet mount. Before the Arri-PL and Panavision mount, many of these cameras had the old Mitchell BNCR mount.

I believe the Panny and the BNCR mounts are refered to as Breech lock mounts.

Hi Chuch,

Are they the same size just different FFD? I will know the answer soon as I am buying a PV mount on Ebay in a few minutes! :lol:

Never worked on Pannys, But I believe it is slightly smaller in physical dimensions then the Mitchell.

Panavision ffd is 57.15 mm or 2.249955"
BNCR ffd is 61.48 mm or 2.419995" Commonaly 2.240"

Are you remounting your Fries?

i know the BNCR mount is basically the same as a PL mount just a lot bigger. Basically take a PL mount x2 in all dimensions. The FFD is a bit closer to the film plane

It's not THAT big. I think it's like 20mm larger in diameter than PV and 15 bigger than PL.

Let us not forget the Russian cameras had their own mounts, the OCT-19 which is the Russian version of the PL but not interchangeable with it although the Russian lenses with OCT-19 mounts can be fitted with PL mounts very easily and the OCT-18 which I'm not sure which western mount that would be similar to but I'm sure it's a copy of one of them. The Kinor 35C and 35H and the Konvas 2M use Oct-19 and the Konvas turret cameras the KSR-1 and the 1M use OCT-18 mounts. These cameras are becoming very common elsewhere in the world and are gaining a foot hold in the US among low budget independent filmmakers because of cost and quality so you may run into them at some point. There were other Russian mounts but I'm not familiar with them. Perhaps Olex would know anyway they are often forgotten and should not be. B)
