MAC at Camtronics has been cleaning and tuning several of my automatic aperture Makiflex lenses. I asked him if they are mechanically quirky to work on, and he responded "Not really". My 180mm f5.6 Symmar needs a bit more work, it was in kinda bad shape. And somebody squirted lube on the blades, a gooey mess. Now a beautiful rare lenses. The Symmars seem to be available only in Europe, as brochures cover them. Now I have the 135, several 150, and 180 Auto Makiflex Symmars. The 135 looks and operates as new. The 135 could benefit from new light trapping. Easy to do. BTW the holy grail of auto Maki lenses is the 150mm f4.5 Voigtlander Apo-Lanthar. Unfortunately most of the Auto Lanthars I've seen in Makiflex are separating. Ken Ruth warned me off the Apo Lanthar!, a Guy In Milan sent him a Maki one, he couldn't fix it! Does separation get worse with time? I think they should have used better lens cement inside the Apo Lanthar cells.
