I have a Zeiss 35-70/3.4 with a wobbly front group, which in other forums has been linked to a broken nylon bushing inside the lens. I'd like to replace this bushing but can't find much information on the lens.
Does anyone have access to a repair manual / a disassembly guide / or has tackled this lens themselves?
It looks like there's no real need to expose internal workings, and just removing the outer grip rubber gives access to the bushing - with only a simple straight bit screwdriver needed for exchanging it with a suitable replacement. I have my doubts if you'll find a factory made part for the job, so it may need to be a reworked part from another donor lens or a DIY part to effect a repair.
