Known Issues:
85mm in particular can easily get oil on iris blades. The proximity of the blades to the riding surface is very close and oil will travel after some time.
Image shift: If shift is due to loose threads, spray and bake will reduce it.
If shift is due to the iris (will shift on the video collimator when the iris is rotated), this is due to spherical aberration and cannot be corrected. Is inherent in the design of the lens.
Service Manual: Disassembly/Re-assembly
Screws: Zeiss
Full CLA: 5-6hrs.
