Default Oly 4/3 lens teardowns ?

Hi guys,
Have any of you seen any blogs or web sites with any disassembly images or similar info for obsolete Oly 4/3 system lenses ?

Looks like I may have to repair one of mine soon and so far it looks like images or info about the internals of any Oly lenses are a well kept cult secret.

(I'm happy to going the 'repair cult' if that's whats needed. )

Cheers,
Martin

You might want to get a price from Olympus repair service. They usually charge a reasonable flat rate and did a good job when I needed a lens repaired.

Go to:
http://www.oiaservice.com/ and see if your lens is listed in the drop down list. If not, go to the "Contact us" page and get email instructions so you can ask them the specifics for your lens. Good luck.

Thanks Steve,
I'm in Australia where everything involving labour charges get stupidly expensive though. Postage back and forth to the USA is also very expensive from Australia.You guys are lucky to get that flate rate repair deal in the US, not many companies do that here.

The repair part looks to be about $10 online, and I have skills and the lens tools, I just don't have any info on the teardown sequence.

If it fails I'd rather put the money on a 12-40mm F2.8 Pro u4/3 lens, and get faster focussing speed.

The actual lens is a 12-60mm SWD, which seems to have a bit of a failure history...

My bad, I had completely forgot that you lived in Australia.

For what it is worth, the Oly repair site for you would be:

http://www.olympus.com.au/Support/Se...d-Repairs.aspx

And it looks like there is a big independent repair site at:

http://digicam.com.au/olympus/

I couldn't find exploded views of that lens. Good luck, I hope you can get it fixed cheaply.

It might help if you mention which specific lens it is.

Someone might have a link to a breakdown and repair of that particular lens.

Yes true, I was not very specific above. It's Olympus Zuiko Digital 12-60mm F2.8-4 ED SWD.

I found this image of the rear ring removed exposing the set of flex cables. I suspect strongly that the aperture flex cable is cracked and that's why the aperture only works between 12mm and 18mm of focal length. Above that it stops responding, below it's fine.

Default Example

Here's a video of the same job on a Canon lens. I'd do it in a clean room if I can get into the one at work (with my 'dirty' lens)...
