Pentax DA* 50-135 SDM
Before you try either of the first two suggestions, get a small screwdriver that fits the screwdrive slot in the end of the lens, then keep rotating the screwdriver to drive the lens focus from end to end. Do this for a few minutes. Then try suggestions above. Wakes my dozy lens up every time.

Pentax DA* 50-135 SDM
Put it on the camera body, cap on. Hold the AF button to force the lens to focus while at the same time turn the focusing ring back and forth. You should see the AF light turn on while this happens. After a while, there's a chance the SDM will become free and so the lens will start to focus co...

Odd K3iii playback behaviour
Yesterday my K3iii stopped displaying playback images on the rear screen - when the button was pressed to display the image that had just been taken, a rotating 'I'm busy, wait until I've finished' wheel appeared and didn't go away. Turning the camera off and on sorted it out, all images present and...

K3iii Charging - A Cautionary Tale
Yesterday evening the battery indicator was showing empty when I turned off the K3iii. This morning I attempted to recharge the battery in-camera. Nothing. Absolutely nothing. No red flashing light, no sign at all of anything happening. So I tried a different USB cable and different socket. Still n...

K3 Mk3 Histogram
In a word, no. That's because the elements that appear in the viewfinder are provided by an overlaid transparent LCD layer with pre-formed elements (for focus points etc.) that are illuminated as and when needed. A histogram is only available in liveview which, of course, uses the back display wi...

AF Button/Back Focus
On my K3ii I'm trying out back focus using the AF button. I seem to of got it working, but not sure if it's right. Am I right to say that when focusing with the AF button, keeping it pressed in I'm able to move to another subject and it will re-focus. In my case that isn't working. I have to keep r...

Pentax K-3 iii - Can it really be this noisy?
Like you, I'd expect better. And I got better yesterday when shooting the K3iii at ISO 3200, albeit different subject and background (sparrowhawk sitting on fence, OOF vegetation behind). Yours looks a bit underexposed to me, might that be contributing to the noise? I've always found that underexpos...

Pentax K-3 iii - Can it really be this noisy?
Thanks for your help Steve. Your knowledge on the subject has put my mind at rest. The last thing I wanted to do is discover that I should have sent the camera back in Amazon's return period, not do so and then end up stuck with it. It seems that it's on spec then. I have tested it this afternoon a...

Dust spots and bug
Hi Astraman and welcome to the site. I think this could be potentially two issues (although please read on to the end), if something is visible while you optically look through the viewfinder, the bug (or particle) could be between the pentaprism and focus screen, laid on the focus screen or on t...

Dust spots and bug
Def not the lense as I took this off at one stage to check and could still see it through the view finder think I’m going to drop the focus screen down to check there if I can’t see it there I will prob take it to be cleaned professionally as I haven’t tried before and don’t want to damage my camera...

Dust spots and bug
If you can see dust spots and a bugs leg on an image you have taken then these are not what you are seeing through the viewfinder. You may well have something on the focus screen or in the viewfinder or on the mirror (as Rick has suggested) but the bugs leg is more than likely a hair on the sensor, ...

Dust spots and bug
think I’m going to drop the focus screen down to check there If you do attempt this, just a few words of caution, it's hinged at the back, with the release clip at the front, the likelihood is when you release it the focus-screen will dislodge itself from the frame and the frame will lower onto the ...

Dust spots and bug
One bit of advice..... take out the focus screen by all means and blow it with a rocket blower. But do not try and wash, clean, or wipe it in any way
