I've just had another go at sorting the lens out without any luck.
It will focus lock on the very odd occasion but 99.9% of the time it won't.
When i try to focus the focus scale on the top of the lens is just keeps spinning and clunking back and forth between the infinity mark and the 1 meter mark.
Regards,
Chris.

How long is it since you used it last? I had one which was not in regular use and I had to "wake it up" by winding the focus ring back and forth a few times. A word of caution though, it got me so annoyed one day, I think I've dislodged one of the elements being too vigorous with the wake up call. My advice would be to have it converted to screw drive.
The last time I used the lens was October 2018, the last race of the season.How long is it since you used it last?

I'll try and give it a 'wake it up' tomorrow.

Hi all,
I don't seen to be having much luck lately, my K3-II has gone in for a check/warranty repair and now I seem to have a lens problem.
My DA* 50-135 won't focus, it tries to focus but just keeps going backwards and forwards and making a whirring noise, manual focus seems ok though.
Is this a sign of SDM failure, I've had the lens since April 2013 and it gets regular use during the oval racing season, it's my most used and favourite lens.
I've tried it on my K5 and K5-II bodies and it's the same on both.
If it is an SDM problem does anyone have any idea about repair costs and where would I send it.
Regards.
Chris.

Sorry for the long delay in replying to my thread, its taken some time to do the lens/body checks I needed to do.
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.

Chris.

** Update **
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.

Well try it before you go Chris; save disappointment!
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.

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.
Regards,
Chris.

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.

Hi all,
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.

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.
