Whitepoint Canon FD 85mm T1.3 S.S.C. Asph.
Summary
Canon introduced the FD system in 1971 after using the FL and R systems on their early SLRs. FD lenses are compatible with all FD bodies. One of the big improvements of the FD system, though, was automatic aperture stop-down. Another big advantage of the FD system was its capacity for automatic exposure. Over its two-decade production run, Canon introduced 134 different lenses for the FD system. These range from 7.5mm fisheyes to 1200mm ultra-telephotos. Older FD glass has become especially popular with cinematographers who claim that the lens’ construction and coatings resemble those of Canon’s famous K35 cinema lenses. Whitepoint Optics was pioneering years ago by being the first company to replace the iris to the Canon FD project to get that round K35 bokeh. Today we offer wide range of customization including a more vintage shiny iris, a matte iris or a full maintenance for the original iris system.

Service

Service Manual: Disassembly/Re-assembly
Full CLA: 10-12? hrs.
Common Whitepoint issues: Loose follower post, leading to loose optics; Damaged follower (it's a very small, flimsy follower); stiff or uneven focus/iris feel due to delrin/teflon spacers being sandwiched too hard and/or improper lubrication; scratchy internal iris ring due to poor machining/tolerances.
Lost Motion/Image Shift: #hrs.
The most common issue with Whitepoint lenses are the weak cam followers (small, rounded, thin-walled delrin) wearing out very easily. Their handmade springs can also be an issue due to compressing more easily than the hardened springs like what Cooke uses. Remove the front engraved ring via the x4 T6 screws, then remove the focus scale by warming it up and sliding it off (held on by glue, with tape underneath to make fit tighter.)
