Converting from Aaton to PL mount
Posted 27 July 2006 - 11:59 AM
http://www.camera-engineering.com takes £450 for the job according to the list.
http://www.lesbosher.co.uk/ Don´t know the cost
I have not received my camera yet as I won it on a Ebay auction . One thing I´m wondering about is what type of timecode that is built into this camera? I´m thinking it could be some early attempts at using timecode and that it´s not supported anymore but please enlighten me if anyone have information about it. I think I got a good price on this auction and as the seller is located in Sweden there will be no custom to pay. I have bought from this seller earlier when he was called "isellarri" so I trust him that it will be no lemon but then again I can´t be sure before I hold it in my hands.

When you get something for less then I cannot assure that you are getting the properly-designed parts and that they are correctly installed. There's a lot to the mount with certain parts made from aluminum and others of stainless steel, with precision shims in a specific "spider" design for the camera. Acurracy of the alignment for depth and flatness is measured in microns.
I don't know the particular vintage of your LTR54, but it is likely using the old original Aatoncode instead of the newer Aatoncode2. I'm not sure about the cost or feasibility of upgrading this, but could check into it if you wished.

I personally own an LTR54 with which I keep in Aaton mount. I have a Canon 8-64, a Kinoptik 5.7, Optar 9.5, 12, 16 &25, and converted Zeiss Contax 35, 50, 85 & 135. The zoom is the only lens in native Aaton mount. The 5.7 is Arri standard with an adaptor, the Optars are Arri Bayo with an adaptor (one quick-release version for all of them), and the Contax are all converted to Aaton mount. Certainly it is less expensive to own these lenses in this manner.
I've learned that Les Bosher uses a two-part mount system. He converts the camera to his own neutral mount and then mounts his PL mount to the front of this. This double mount introduces two points for play and it can be nearly impossible to get a zoom to track in straight to the center. (If the mount is not perfectly flat and centered then as the lens zooms the image will drift out of center.) This can be not only annoying but can lead to softness on the edges of frame. It will take much more time to swap between mounts if you use Les' PL mount.

I´m leaning towards sticking with the Aaton mount and getting a set of zeiss contax some wideangle superspeeds and maybe a Nikon tele. I´m however impressed with this old Aaton. I did a test run with it and looked for scratches and it passed without any problems, but what really impressed me is how quiet it was. I wouldn´t even compare it to a SR1 it´s much quieter than that. One thing that would be nice to have is a better manual than the one that I have downloaded from Aaton. Is there some kind of service manual that is more detailed? And one last thing, how do one know if the camera have a pellicle installed?

Converted Contax still lenses can usually be found for $500-$1000 each. But they do not exist in the wider lengths. Take a look at my list of lenses. You get cine lenses for the wider lengths and then the Contax lenses starting at 35mm. But your workhorse lenses will always be from around 9mm to around 25mm.
