Vivitar series one 70-210 F2.8 repair guide ??

[tammons]

Anybody have one, or a link to one online ??

Or even just an exploded diagram would be fine.

Major oil on the aperture blades so I would guess someone used the wrong lube on the helical.

Very nice lens though and very sharp and I got it cheap.

It looks like the tube comes apart towards the back of the lens with a spanner or something like that but not sure.

Thanks

Never mind.

I was able to figure it out and took the mount end apart to
access the aperture assembly.

A little Tricky to take apart.

Never seen a diaphragm assembly so loaded up with oil.

Tried to clean the blades, but no go.

Had to dissemble the aperture assembly and clean each blade individually, the housing and all.

It was a mess.

I hope you took pictures to go with the guide that you're going to write
