If you intend to mount Pentax K mount lenses on your 4/3 mount Olympus using a PK - 4/3 adapter, make sure you remove the flange that protects the aperture stop down lever first.

If you don't, you will damage the electrical contact pins on the camera. Worst case, it could break off two pins.

Damage to flange, which should be removed by unscrewing the three screws, BEFORE attaching the PK lens.

Damage to the pins on the camera. When it comes to trying to remove the lens, the flange gets caught on the pins (I guess when the lens went on, the flange pressed these two spring loaded pins down, so it was no problem at the time). This stops the lens from being removed, because the pins are no longer pressed down. I'll have to remember to remove the flange if I buy a PK - 4/3 to use with any of my PK lenses.

Looks like you were very fortunate not to be faced with a very costly repair to your camera. As it is, you can clearly see the evidence of significant sideways pressurehaving been applied to the sensor pins resulting in thehole openings in the bodybeing deformed.

Thanks for posting as it is a good warningto everyone contemplating the use of non OM or non ZD lenses that thereare risks involved.

I had to do the same for my Vivitar ....I just covered the lens really well and with one snip of the metal sheers and it was a wrap!
