Dead K5 ... Help.
Surely if the K5 is having problems, as with anything, and you can't use it as it was intended then it is 'not fit for purpose'? Amazon, or anyone else for that matter, would have to attempt to fix the issue/s and you'd have to allow them the chance but if you've lost confidence in the product I fee...

I need advice, again!
As some of you may have seen, I have posted a Image of the Diamond Ring that I bought my Wife 20 yrs. ago. However, I have found that photographing a Diamond Ring is not quite as easy as I thought it would be. I tried to capture the brilliance of the Diamond in the light box that I have. I used...

I need advice, again!
A few things worth trying that may help. I personally would put the camera in manual mode and stick it on a tripod, if you have a shutter release use it, and use the Mirror lock up function Try taking a three to four images and place your focus point (red dot) on different areas of the ring then...

K-7 turning off the autofocus
I was trying to take a shot of an insect through the 55-300 lens with my K-7, Bright sunlight in the garden. I tried shooting in both P mode and M mode. Each time I pressed the shutter, the lens would move and the focus I had adjusted was overridden. I tried changing the focus selection on the c...

K-7 turning off the autofocus
You can set the camera to manual focus using the three position control on the left side of the lens mount. AF-S is conventional autofocus, AF-C is continuous (for tracking) and MF is manual. You can also go into the menu settings and disable the autofocus on the shutter button, and instead have it ...

K-7 turning off the autofocus
Most/early all lenses have a manual/auto focus switch built in. Just switch this to OFF.

K-7 turning off the autofocus
Hi, are you mis-understanding quick focus on what I assume is the DA not DAL lens? I assume it works the same way as my KR. To refocus finely from autofocus you need to have the first position on the shutter button depressed before you turn the focus ring otherwise it will refocus back to wha...

Sigma DG Macro problems
I think the macro switch slightly reduces the minimum focussing distance, so you can get treater magnification by physically getting closer to the subject and still being able to focus. Obviously if you have a subject in focus and then flick the switch to macro, it will make no difference to the ima...

Pentax F 70-210 with a screw loose
Thanks for the advice. Invested in a couple of tiny screwdrivers and have managed to get the screw back in its proper place, no flying springs or loss of mini ball bearings.

Catch-in-focus with a Sigma f8 mirror
I have, I'm sure, followed the instruction book when trying c-i-f on my K7 with the Sigma, but without success. In the book it says as something comes into the (pre-set) plane of focus, the shutter will fire. Should it work on a static subject, by slowly focusing "through" the subect, firing whe...

Infinity Focus - Pentax 50-135
My 50-135 will not lock onto focus at infinity anymore. This happens right across the zoom range with both manual and auto focus. I've tried it on two bodies with the same result, so I assume it's something to do with the lens. The motor seems to take it to the focus point, at infinity, but it does ...

Infinity Focus - Pentax 50-135
Have had a similar problem with my da 16-50. This tends to occur more in low lit conditions. Strange thing is that it comes and goes. Only thing i do is change to manual focus and set things into there. In the end, at infinity manually setting your focus is quite straight forward. Sorry, more than t...

Infinity Focus - Pentax 50-135
Hi I do have exactly the same problem with the 40mm DA on the K5. Both are new. If focusing at infinity, the AF will not confirm and not release. Sometimes after waiting for a while the shutter finally fires. I also have the 70mm and the 21mm. In exact the same situation the 70mm will work fine...

Infinity Focus - Pentax 50-135
Reply from Asahi Photo Ltd in response to an email giving details of fault. "We can repair your 50-135 DA Lens, it seems that the focus mech is out of calibration. The cost to repair and service the lens would be £72 which includes parts, labour vat and postage back."

Annoying dots on pictures
I also got dust into the viewfinder the first time I used a Rocket Blower and had to have it professionally cleaned to remove this. However since then I have learned to use it correctly and have not had any further problems whatsoever. It's a shame they don't come with any instructions on how to use...
