M50f1.7 problem
Right Stu If Stefan's cross-section is the right one (and my recollection is just plain wrong :oops: ) then it looks like most of the bits are of different diameters. It is hard to see how the lens would assemble (and still feel right) unless it's the double element (fourth group). Lets check -...

M50f1.7 problem
Geoff it's 6 elements in 5 groups, still good try I would not even start to guest out of my head. :? It's probably the middle (single) lens. Flip that over and give it another try. Don't ask me how I know......:oops: To be honest it is hard to see any difference in lens curvature looking at a ...

Sandisk Extreme III 8GB SD Card and Pentax K7
Hey this is getting scary - been awake too long today. Just realised I put the card in the K10 not the K20. So no joy with the K10. K20 works fine so back to square 1... I have not put the firmware upgrade on the K7 as not sure what extra this provides. I wonder if it gives 8GB support?? An...

Sandisk Extreme III 8GB SD Card and Pentax K7
The simplest explanation is a faulty card. Well John I have just updated the firmware on the K7 put the card back in the camera and it showed the 34 images on the card and then let me format in camera. Put the camera in drive mode and ran off 30 or so shots with no problem. So will just have to wa...

Sandisk Extreme III 8GB SD Card and Pentax K7
The 30mb/s are the new ones, it could be that the camera find them strange but then it shouldn't recognise the card to begin with I believe. You suggest here that the K7 may not recognise the "new" 30MB/s Sandisc Ultra III cards. In truth these cards may have been new when the K20 first appeared, bu...

DA*50-135 SDM noises - is it a cause for concern?
Presumably you have checked that both the body and lens are set to autofocus :?: It is easy to forget to switch back if you use manual focus (for macro work for example).

K-m Mode Dial not working
John A Very big thank you, I no I'm a novice with this Camera but that was so simple. I had taken the Lens of whilst the Aperture Ring was not set at A. Put the Lens back on and set it back to A, Mode dial works ok now. Thanks buddy, That was a bloody good tip. Me thinks I really need to...

K-7 mystery line
I would suggest demanding a replacement, if you agree to a repair it could be ages before you get it back. The camera developed a fault in less than a week, you are well within your rights to ask for it replacing, in fact IMHO it would be a very poor retailer who tried to insist on a repair.

Focus screen and mirror box
Some how today the focus screen had come out of my camera, so now I have dust and dirt in the mirror box, and ideas how to clean it and what to use?

Focus screen and mirror box
Compressed air like Dust Off might do the job but play it safe and get it to a listed Pentax technician.

Focus screen and mirror box
DIY job. Pentax expects owners to change the focus screen them selves I would avoid compressed air as it may drive dust further into the camera. Blower to remove loose dirt and/or very clean brush like an artic butterfly to wipe off base of prism. Avoid touching the mirror as it is front silve...

K-7 won't stop lenses down....
Hi - on hols in the States and my K-7 seems to have stopped stopping lenses (any lens) down from wide open. Optical preview no longer works. And dust alert has become greyed out as an option. Luckily have a back up K100DS but not very happy.... Manual focus or auto focus makes no difference; ...

K-7 won't stop lenses down....
Ensure the 'A' setting on the aperture ring is selected with any lens that has one. Try cleaning the electrical contacts between camera and lens on camera and lenses. Leave the battery out for a few hours in case of a software bug. Dust Alert is greyed out with a manual focus lens. Optical Pre...

K-7 won't stop lenses down....
Thanks for the suggestions. Sadly this situation is the case with all of my lenses, including the kit 18-55 where AF and aperture ring shouldn't be an issue.... Will try the battery trick though and report back if it works. I'm kind of thinking that because the camera is refusing to stop down a...

Getting my IR remote to work
When you have set the function menu to use the remote, does the self timer light blink? If it does, it could well be the remote that's faulty. To test it, point the remote at the lens, focus on the IR transmitter LED, press one of the remote's buttons and hold it pressed while you take a photo o...

Getting my IR remote to work
The remote operation, by default, will only release the shutter. If you want AF as well you need to set this to 'On' in the Custom menu. NB. The remote needs to be aimed at the front of the camera. To set up the camera for remote use, first press the Fn button. Next, use the 'Up' butto...

Focus point LED's
My left-of-centre focus point LED has stopped working. The focus point itself still works, in so far as the camera will still focus with that point selected, and the green hex lights up when focus has been confirmed by the camera. I have given the camera a clean as far as I can without taking it...

Focus point LED's
Dont think theres much you can do yourself, looks like a visit to the camera shop, personaly its an issue I could live with, it could be expensive to rectify.
