My E510 has a faulty mode/power switch. (Hard to turn on, camera will turn off when bumped).
The local Oly service centre wanted near half the cost of a new body to repair it. The quote says they want to replace the top and back panels!.
I ordered a new 620 body.
I suspect all that's happened is the connector came loose. Their diagnostics basically consisted of a visual inspection and looking up the fault decision tree by the look of it. It's also possible they thought my LCD was broken as I have sticky tape holding a screen protector on.
It was the E510's 2nd service - the first one was basically a clean/calibrate - I think I managed to get dust on the focus sensor.
The SSWF is all well and good, but the focus sensor is even harder to get to...
I suspect the SSWF shook the dust off the sensor fine, and neatly deposited it on top of the focus sensor that lives in the bottom of the camera. It was almost certainly dust as the problem occurred after a visit to Jordan. I was doing lots of lens swaps out at the archaeological sites and it was very dry and dusty. At no time did I have any artefacts on images, the focus response just got sluggish and inaccurate.
In a week or so I should have a E620 body. Only I doubt contrast-detect AF is going to work with my older lenses
