p.1 #1 · p.1 #1 · I may have to say goodby to an old friend, or not yet ?


This morning my trusty 200 f/1.8 stopped auto-focusing abruptly. No MF either, as it usually happens with that lens model.
Below is the last shot I got with it.

The lens was made in 1997, and I bought it from KEH ten years ago. I used it in moderation, and I had even avoided shooting it in Servo AF mode.

Obviously, we'll attempt a repair, but I ain't got much hope. I guess that's the sort of a risk one should accept when getting deeply obsolete lenses.




1DX + 200 f/1.8

That's sad to hear on so many levels.

RIP if repairs don't work. Sometimes you just have to let it go.

After doing a couple of regular mechanical cleaning attempts of the lens contacts with no effect, I decided to do a bit of a chemical clean, and that seems to have brought the lens back to life. Both FM and AM seem to work as they should, perfectly normally. Perhaps the time is not up yet for my 200 f/1.8 ?

FM and AM? Has the lens started to do double duty as a radio receiver?

That's a good one, Ilya.
You've gotta excuse my incoherent writing, I am still in a post-traumatic phase.

That was a close one! Let's hope you get many more good years from the lens.

What is a "chemical clean"?

What is involved to get to the encoder ring and clean it?

Good to hear that it isn't broken yet.

I've used rubbing alcohol on microfiber tissue, but there are some other specialized compounds to clean electrical contacts ( corrosion, grease removal).
The lens contact disc is not difficult to remove from the mount, but that is not needed for good contact cleaning.

I am still concerned about the issue because those contacts looked clean to my naked eye even before I rubbed them with alcohol, yet the lens was dead.

Great DOF shot of GBH, Peter. Too bad that your legendary monster 200 F1.8 stops working.

I really wish that Canon would either (1) support a lens like the 200 f/1.8... or (2) offer up a replacement.

Part of me is surprised that a replacement USM motor hasn't been made by some enterprising company... getting it installed would be tricky, I assume

Of course, this is what sucks about the electronic lenses. At some point, they will fail and not be repairable. That is one thing if the lens is a couple of hundred bucks... but another thing entirely when the lens is well into 4 figures.

My biggest fear when I had this lens. There were some repair shops with parts here in the US. Let me know if you can't fix it there in Canada.

I'm sure Peter's fingers on his left hand was slightly faster than those on his right hand. He probably meant MF.
But maybe that lens has a special radio feature, no?

Glad you were able to revive it!

You probably already know, but Midwest Camera Repair is worth checking out if you run into more trouble. They claim to have at least a 50% success rate fixing this lens, depending on the issue.

Pareng Pete, before you dismount it from the camera for storage, try to set the focus to your most used distance. In the unfortunate event that it conks out, you can still use it by focusing with your feet, ala macro lens on rail.

Thank you, indeed, Midwest Camera Repair is on my list should the lens give up the ghost for good.
