Canon Lens Repair

[Paul C. Perkins MD]

I've got double trouble in Smallville.

Both of my 50mm F:1.2 Canon lenses have developed frozen diaphragms. I try to open them much wider than about f:5.6 and the diaphragm rings won't turn. It feels like the lubricant has turned to caramel. . .

Next month is Leica/Canon month - so I'm reduced to using a collapsible 50mm F:2.0 Summaron. . . Not bad really.

Who can fix these two old birds?

DAG should be able to. Sounds like a CLA on the lenses will do it.

Just had a 50mm f1.2 CLA'ed by Essex Camera Service in NJ and would /will send any Canon lens that I need worked on to them. Got the lens back in about 3 weeks and was a top notch job. I e-mailed first to fine apx. cost and shipping. $90 very well spent. Send an adapter ring so that they can fine tune the focus adj. I am using the lens on an M8 so I can see the results right away.

I have had 4 Canon ltm lenses cleaned and lubricated by Fotocamera Repair, Inc. of Lake Worth Florida. Peter Smith, the proprietor, is a well-respected Nikon repair guy, but also works on other brands. Costs ranged from $60 to $90 per lens. Great guy to do business with.

This sort of work on the Canon 50/1.2 lens should not scare any experienced camera repair person who is capable of cleaning the auto diaphragm in an SLR lens. One very obvious retaining ring holds in the lens block. As long as they aren't stupid enough to lose the infinity shim (SLR lenses also have them), they should be able to do it fine.

I know DAG will do this sort of work, but he's a specialist, and the queue can be long.

If you have someone you would trust to clean a $300 Nikon SLR lens, they can probably do this lens.
