K3II Intermittent Overexposure Issue
John
Using the same lens ?

The lens works fine on my K5II body.
I've only got one more meeting of the season in October so I'll try a different lens.
Regards, Chris.
Have you tried it on the K5ii since the issue?
If it is definitely fine on one body but not the other it does point to a camera problem. Definitely worth doing some further tests to make sure.
Well try it before you go Chris; save disappointment!

it only seems to happen after approximately 900 /1000 images so I won't really be able to check beforehand but I will put one of my other lenses on my K3II for the next meeting.
There's another track I go to now and again whos season doesn't end until November so if I get a chance to go there then I'll put the 50-135 DA* on my K5II body and see what results I get.

I put the 50-135 DA* on my K5II body and took 1102 shots at Sundays race meeting, the lens performed faultlessly, no over exposed shots at all.
Just need to check my K3II body out with a different lens.

Chris.
Have you got a spare you can swap over with when the issue occurs? If that solves it it'll confirm the problem. If not it would surely be the camera itself, but it's odd it'll take hundreds of shots in a session and then fail, yet be OK again next time. I'm guessing you'd have charged the battery in between sessions?
Edit: One thought that comes to mind is if the camera is getting hot in an extended session and that is somehow causing a problem A capacitor failing perhaps causing it to run hot?

however, that would include using the flash for some of them too. So achieving up to 1000 before it fails seems to be par for the course.
What is the battery charge indicator showing when the failures start to occur?
All the lenses I tried on my K3 II gave the same intermittent overexposed results.
All the same lenses I tried on my K5 II worked perfectly.
As the K3 II is still within the 2 years warranty period I called SRS earlier on today and they said to send it in for a check/warranty repair.

Just received my K3-II back from SRS/John Pye Technical.
Letter inside box says....1000 shots taken, no fault found.
I'll be using at a race meeting this weekend so I'll give it a good work out and see what happens.
Regards, Chris.
As an aside, you can extend their life by turning the camera off between shots.

I had a recent electrical fault on my K1 and putting it into continuous drive mode and firing it off would present the fault every time. They replaced the electrics board.
Good luck

Well....I only got to shot number 129 and guess what, the over exposure fault was there again.
I'll phone SRS again in the week.

My K3II has an intermittent overexposure issue, every now and again every other photo is overexposed.
I photographed at a race meeting a week ago and everything was fine, no overexposed images, at the meeting I was at last Sunday I had quite a few overexposed images, but it was only every other image.
Removing the battery seemed to cure the issue for a while.
This happens on single shot and on continuous mode too.
Has anyone else had this problem with their K3II?
Below is an example of the issue.
