It started yesterday - went out to take some shots of the other halfs new Rose and about half of the shots were well over exposed. I thought it was me, then thought it was the lens so I changed it but the camera kept over exposing!
I took the camera in doors,set it up on a tripod and took a load of test shots. For example if I took 10 shots all at the same setting on manual - about 7 would be ok but the rest would be over exposed. Tried several lens but still the same. Strange thing is the info for each shot were all the same and it shows that on the exit.
Get it checked quick whilst you are (hopefully?) still under warranty.
It's the aperture motor sticking some times, or driving the aperture further open than it should etc. It's worst on semi manual modes such as Av and Tv, because when the lens sticks closed the camera meters on this false light value and then calculates a massively off value to compensate.
I don't know if it was a bad batch of components but mine was fixed easily and effectively. Was your's a particularly early production model?

Think my K30 has caught the dreaded aperture drive failure illness - seeing this post of the problems Richard had and also googling the problem mine seems to have the same symptoms - looks like a trip to Johnson's but luckily I live a bit closer than Richard - about 5 miles away!
Good luck, 5 minutes away sounds great![/quote]It started yesterday - went out to take some shots of the other halfs new Rose and about half of the shots were well over exposed. I thought it was me, then thought it was the lens so I changed it but the camera kept over exposing!

Hi,
Anyone else with a K-30 experienced this?
Happened a few times to me recently on holiday. Same settings in Manual occasionally returned nearly completely black images for no reason. Kit lens, nothing changed setting wise.
Googled it and found there may be a widespread issue with the K-30 due to a failing aperture drive motor? Just wondering if anyone else had experienced this and thought I'd make people aware if it hadn't been mentioned before?
In my case I turned the camera off and back on again quite a bit, but it looks as though it's just random so that wasn't really helping anything.
