How to disable the back LCD-screen on my Pentax KP?
There isn't a 'shooting info' display on a K1 and the worst thing it can do when you turn it on is to splat you straight in the eye with that damnable status screen. Yes, you can turn it off after the event as described above but how do you make sure it stays off - preferably, for ever!

K5 Lens Release Button
Thank you for the info Michael, I will try my luck with Ricoh.. I have just this moment found out that a very large paper clip is almost an exact fit in the tiny little hole and requires very little pressure to release the lens. I have also just realised that the lens is only locked in place by the ...

One for the techno wizards!
I have a K20D converted to 650nm IR. This week I decided to try my Sigma EX DC 10-20mm f3.5, Pentax DA☆ 16-50mm & 50-135mm on it, and discovered an issue. The images look like a film of vaseline has been applied to the lenses! They don't look out of focus.... just hugely soft. I did f...

It would be helpful if you could post an example of an image? Meanwhile, IR light will focus at a different distance to visible light and not many lenses are corrected for this. Some lense have an IR correction mark on the lens so this can be accounted for. Focus normally and then move the point...

Basically you are seeing what little bit of red can be shown as all the other colours have been removed. I would first convert that to monochrome. It needs a closer focus setting, which may well look out of focus through the viewfinder. It also needs a more defined subject to practice on. I would su...

MX-1 lens won't retract
Does the camera work (and focus) well otherwise?

Does the camera work (and focus) well otherwise? Yes it does - I should have mentioned that in my post.

X5 problems
When all else fails, remove battery for a while, insert battery and try again. If that doesn't fix it, try a factory reset. Did the problem start with the onset of hot, dry weather? If so, static electricity might be the cause. The user manual for my K3 says "In rare cases, the camera may not ope...

X5 problems
Highly doubtful that parts still exist for the X5, I have emailed one possible camera repairer and am waiting for them to get back to me. If they quote £750 I think it might be cheaper to buy a new (hate to say it) non Pentax bridge cameras!!!

DA 55-300mm will not focus on K70 body with any settings
My 18-135 works perfectly, but the DA 55-300 will not focus with any settings, i have tried multiple combinations and a factory reset. The in lens motor works constantly but will not focus at any length in auto or manual. when the camera is set to manual the lens continues to flicker between manua...

DA 55-300mm will not focus on K70 body with any settings
Can you tell us which version of the lens it is. There have been several versions. The latest one (PLM version) has the focus motor in the lens, previous versions were focused by a motor in the camera body. Steve

I have the PLM version. I have updated to the latest firmware and that didn't make any difference. it is the motor in the lens that twitches constantly but wont focus. switching the camera to MF doesnt stop it

DA 55-300mm will not focus on K70 body with any settings
It may be worth cleaning the contacts on both the lens and body. Do you have another body you can test the lens on?

DA 55-300mm will not focus on K70 body with any settings
I dont have another camera, no. this is the only lens not working correctly, and I have cleaned the contacts already. I suspect it is beyond repair. just taken it out in bright light and it was shifting wildly between iso 200 and 1600, f4 and f6 and shutter for 1/20 to 1/400, it doesnt seem to kno...

While it's on the body, see if adding a bit of CW/CCW torque causes the shutter speed/ISO to stabilise.

It sounds like a cpu issue.
