Service Manual: Disassembly/Re-assembly

Full CLA: #hrs.
Optics can be dropped out as an assembly much like a Cooke (with similar brass rollers), but the focus system is helical-based rather than cam follower-based. See above disassembly guide for details.

In terms of serviceability/build quality, they are almost equal to TLS rehousings, and much better than GL Optics.

Having issues with not having full travel at infinity on the 135mm? Check the cone. It's a two piece design where the inner baffle is just press fit into the cone (not glued), so if the lens is jostled enough, the inner baffle can loosen, thus limiting full travel. Gluing the baffle into the cone is not a bad idea.

C&A Optics: #hrs.
No centering options (outside of just spinning random elements) available.
