Hello,

I've got a number of cooke kinetal lenses and was looking to get them converted to Arri PL, but some people have suggested that it would be easier and cheaper to use an adapter to utilise them.

Does any body know who does a good arri standard to PL adapter?

Regards,
Steven

Steven,

Try Visual Products, Cinematechnic or Les Bosher for quality PL mount adapters.

I have found some "budget" PL mount converters on e-bay. One I purchased was made of stainless steel and was too narrow to fit an Arri standard lens and also the tabs were 2.20mm instead of 2.00mm thick. I purchased another one from a different seller, it was made of chromium plated brass. It had tabs that were out of spec as well! When the tabs are a long way out of spec the camera mount will not accept the lens mount....a problem.

Hi,
I have a set of these myself. They're the older Arri st mount, which means the whole aluminum barrel turns when you focus (on later st mounts, the barrel is stainless and the lense rotates internally). These older Kinetals can't be fitted with a regular PL adapter, which squeazes the barrel into place (with a ring or set screws). As far as I know, they can only go on an Arri st adapter (available for Arri and Eclair cameras). You might want to speak to Les Bosher on this issue though. His adapters are known to be top notch, maybe he can work something out. Might be costly for such precision custom work, though. Let us know what you come up with; these Kinetals are great glass.
Good luck,
Marc.

Les Bosher makes an adapter that will work fine on the Kinetal lenses, I have a complete set and Les's adapter. It is not a special order, it is one of his regular designs. You want the "Arri PL - Arri Standard with Spring loaded levers (for Cooke type Lenses)", you can find it listed on his web site under Mount Adapters.

http://www.lesbosher.co.uk/

One of the things you need to be aware of with the Kinetal lenses is that they protrude pretty deeply past the Flange on the camera, which makes them interfere with the spinning mirror shutter on many cameras. Make sure you check that the PL mounted Kinetal will clear the mirror shutter on whatever camera you want to mount them on. They will hit the shutter on the Arriflex 16SR and 16SRII. Mine cleared the shutter on an Aaton LTR, but they may not work on all LTR cameras. Again, always check because the Kinetals do protrude further into the camera than most other ARRI standard mount lenses.

Best,
-Tim

Thank you, Tim. A few of my Kinetals have a drunken barrel, shaky on the arri st mount. Since I work with an Eclair ACl and I have a PL adapter laying around, this is good news.
Best regards to all Kinetal spinners out there,

Marc,

Not sure what you mean by "a drunken barrel" and your Kinetals should not be shaky on the Arri ST mount (you are lubricating the barrels with ARRI grease (or the lower cost alternative Vaseline) before you slide them into the camera mount aren't you?).

And I need to be clear. Les makes the "Arri PL - Arri Standard with Spring loaded levers (for Cooke type Lenses)", it is one of the standard adapters he makes, but it is not the same as anyone else's standard PL mount adapter. It is very specially designed to work with the Cooke Kinetal and Cooke Speed Panchro lenses. Les makes quite a few unique PL mount adapters to deal with the wide variety of ARRI Standard mount lens designs out there.

And I second your "Best regards to all Kinetal spinners". I dearly love the little Cooke's and I think they make fabulous images.

Best,
-Tim

Hi Tim,
Yes, I do grease them. A few though, even by eye, are slightly deformed, the groove on the barrel when you turn it looks like some crazy kid's bicycle front wheel (so to speak). By the way, do you know if these aluminium barrels can be straightened, if there's a tool for this that our dear specialists have in store ?
Regards,
Marc.
P.S.: my last film was shot with Cooke Kinetals, straight 35mm blow-up, and it definitely is great glass
