Exposure problem
Hi Karl, Can't think of anything else at present - if I do, will post. Having just said that, if the familiar click isn't happening, have a look at the lens locating pin and the focus drive. The pin is to the left of the electrical contacts/ the focus drive to the right as you look at the camera le...

I would agree with JohnX - do not try a firmware upgrade until you understand the full extent of the problem. Battery out - for a couple of hours and turn on to get any residual charge from smoothing caps in the power line to discharge Memory card out. Lens off and clean contacts, look for ...

polchraine: will do as suggested. Have had a look at the pins. When I press the lens locating pin, the focus drive does not budge. Btw, what is'pinging'?

Just a thought: (Do this with the lens off) Do check that when you switch from MF to AF-S or AF-C that the focus screw pin retracts and pulls out. i.e. when on MF, the focus screw is retracted (flush with the body); when on AF-x, the focus screw protrudes from the lens mount. The screw pin ...

Hi Karl, What I meant by 'pinging' was to try and flick or prod the locating pin, or focus drive shaft if it wasn't protruding properly to see if it might spring out and back into its proper position. Andy

MattMatic: have checked the pins after having left the battery out for about an hour. The pins work as you said: When in AF.S and AF.C, the focus driver retracts. In MF, it is flush with the body. When in AF.S it makes same purring noise as when I press the AF button on the back of the body. Now...

Maybe try the firmware update as per JohnX - and putt the file in the root of the card AND make sure you have a fully charged battery in the camera before doing the update and leav it until its finished. Otherwise it sounds as though there may be a focus drive problem which could mean a repair job. ...

MattMatic: Try pressing the "AF" button on the back of the K20D. If it makes the same noise when you press just the AF button then it's a focus issue (Normally the camera will auto focus when you half-press the shutter, but this can be adjusted in the custom menus) As I said, you are right. It ...

Just to confirm to Johnx: when in AF.S and AF.C, the focus drive PROTRUDES, when in MF, it is FLUSH. Which is correct. will do the upgarde today, using Anvh's pdf. The upgrade came with a readme.txt file. will let you know what happens.

Have successfully upgraded, using the pdf instructions. Very clear guide, must say...idiot proof, to boot... Now, I can use the AF.S option, but ONLY in the Preview mode. I have to focus manually. If not in Preview, it still purrrrrs along. Any ideas?

Exposure problem
Question: Does the lens actually focus while it is "purrrring"? (ie does the focus ring move) Question: Does this happen with both the 18-55 and the 50-200? (If it only happens on one lens then maybe you have a focus clutch problem. You can check the lens: hold the lens so you are looking at the ...

ABOSULUTELY STRANGE. Just returned from the surrounding hills and used only MF. On return uploaded images to PC and also deleted the upgrade file from the card. When I read MattMatic's post, I found that the focus ring was actually moving, focusing, I guess. But, much more, it actually focuses an...

Newbie - New Kx, Flash not working?
I think the flash control is accessed via the fn button on the back. You can download a manual from Pentax's website! :) Welcome to the forum btw!

Newbie - New Kx, Flash not working?
To check, I just when through this with my Kx : - Wheel at the top is NOT in the "no flash" mode (next to "M"). Any other mode will be fine (Av, M, Green, etc...) - Press the flash symbol under "OK" on the back, and select "Manual" (first option) or second "Red Eye". Press OK. - Press the F...

Newbie - New Kx, Flash not working?
I'm not sure if it's set up in the same way as my K-m, but as delivered that would automatically pop the flash up in green mode and fire it as and when it felt the need. I swiftly discovered how to turn it off, so that the flash only comes up when I press the button (otherwise the camera meters and ...

OLd Cokin filters
You can still use old Cokin filters, it's just that most of them probably won't be worth the bother. The ones that are still useful for digital work are ND, ND graduated and polarisers. The ones that are not so useful are those used to add or correct colour (can all be done in-camera now using...

OLd Cokin filters
No reason why the filters won't work. However apart from the ND, soft focus, star burst and polorizers, make sure that the WB is set correctly for the coloured grads otherwise the auto WB will try to change the balance. Best thing though, is have a play with the filters, digital images cost nothing...

K-x Bulb mode write-time slow?
Sadly, with the K7 this cannot be fully turned off, probably the same with Kx (I believe K20 is the same way). As I understand, in ANY bulb photo over 30 seconds the frame subtraction is forced! In some photos over the specified maximum ISO and shutter speed, this also happen. I do believe this ac...
