I remember servicing early computer systems where the gold edge connections became quite dull looking (could have been resin residue, perhaps) & we used to use a soft eraser (pencil rubber) first following by alcohol (isopropyl preferably but metho otherwise & buffed off), so if a lens connector (or SD card) looks dull, it's worth cleaning properly.

Spent many happy years cleaning computer edge connectors and reseating banks of memory chips with great success. Can’t say I’ve ever had to do it with a camera lens connector pins though, not even when camera and lens has been subjected to many hours in humid salt water conditions (whale watching). Is Olympus unique in seemingly having this as a problem? I can understand it perhaps within a microSD to SD adapter where perhaps they’ve cut some corners but on lens to body connectors? Really?

No, not normally, but when issues arise with a lens then it's at least worth trying.

Re: EM1 MKII Lock Up

It’s probably an unwitting part of the process anyway. Try another lens... yep, that works. Put the original back and as if by magic that works too!
Having commented that I’ve never had such an issue on several other cameras and lenses I’ve maybe overlooked the fact that just about everything else is knackered on the cameras! Buttons stuck, pop up flashes that don’t (pop up)

All ILC cameras can have the issue. A particular Nikon camera some years ago needed it as it was very sensitive to the voltage (which is why I have a supply of Deoxit).

Please don't use a pencil eraser, the little bits will get everywhere inside the camera.


Fumbling while mounting a lens and touching the connectors with dirty fingers is easy to do and forget about. The sticky mess will transfer itself to the contacts inside the camera as well.

When trying to rectify a randomly re-booting server the first step was always to remove the SIMM's, clean the edge connectors with an ink rubber (pencil rubbers have too much gum, shed too many bits, not abrasive enough) then wipe with high purity IPA only (too many additives in meths) and refit. Surprisingly effective, I found.

You should read a wonderful old book "The Soul of a New Machine" 1981.
https://en.wikipedia.org/wiki/The_Soul_of_a_New_Machine
They build this crucial new prototype and it is hopelessly unreliable, they try all the normal things.
In despair they lift the chassis a foot off the floor and drop it. Reseat all the boards, and it then works perfectly.

Relax, I wouldn't use it in that situation either, but...... if by some chance I really felt the lens contacts look badly discoloured & dull then I may use it (the soft silicon rubber type only though) with the lens horizontal & the contacts down & then followed up with cleaning liquid on a cloth to thoroughly clean every skerrick of rubber possibly left behind.

Re: EM1 MKII Lock Up

With regard to the Lock-Up malarkey, if the manufacturer incorporated a data logger within the system (stored in E^2 memory for example) it would be a simple job for them to diagnose issues such as this. Other manufacturers do this, eg Leica, which I know to be fact, revealed to me in written communication when my M240 went back for investigation.

Re: EM1 MKII Lock Up

As a computer techie we used to use what I assume to have been specially designed rubbers for edge connectors. Twas neither pencil nor ink and was a funny dark beige sort of colour and yes, it did shed bits everywhere so a blast with an air duster or a waft with a brush cleared all the detritus.
I now feel a need to Google ‘edge connector rubber’. (Wonder what delights that will bring up)

Edit: nothing obvious in the Google search (or even remotely pervy!)

Olympus do store fault data. You can see it by accessing the appropriate pages in the hidden areas. You get to them the same way you find out the number of photos taken, but on a different page.
