Not focusing to infinity
I've just bought a used Pentax FA 28mm F2.8 lens. Judging by my split-image screen when attempting to focus manually on far-off subject, this lens can't focus to infinity. I don't mean it goes beyond infinity, I mean it doesn't even go as far as infinity: actually not far enough to focus on some...

Not focusing to infinity
Pete, When you shake the lens - do you hear anything abnormal? I had a similar problem with a K mount A version a while back - and this lens had no visible signs of a problem. There was a clunky rattle - something moving around freely. My feeble attempts to diagnose and repair failed misera...

Not focusing to infinity
Pete, That sounds ominously like my lens. I managed to tighten the front element (which I suspect had been removed in an attempt to repair the larger problem). There was still internal movement when I shook the lens, and the infinity focus was still erratic. I think you're correct to d...

2G card stuck at 1G capacity - any fixes?
OK not Pentax related, but I think I destroyed one of th SD cards I generally use for my Pentax... I took one of my 2G SD cards that I've been using on my SLR for over a year and stuck it into a point and shoot.. The damned thing formatted the card down to 1G. I cannot find any way to reformat i...

Tamron Macro 90mm not working with Macro Tubes! Eh...?
Just been playing with the Tamron 90/2.8 Macro 1:1 SP Di that we bought today at SRS, and one of my first ideas was to put it on the end of my macro tubes, just to see what level of magnification I could get! But it won't work!! The shutter just will not fire! It's on manual focus. Tubes work...

Tamron Macro 90mm not working with Macro Tubes! Eh...?
Yup, fully cleaned just in case, body on MF! Half press, doesn't give focus confirmation either.

Tamron Macro 90mm not working with Macro Tubes! Eh...?
not sure what to do? Nor me. How many tubes? What make? Do they all behave the same? Do they behave the same on your old K10D? Do you have a DVM to check electrical continuity between front and back? Post some pics of a tube front and back.

*ist DS misreports battery as dead
My *ist DS (c.3 years old) has an irritating problem that occasionally happens on a change of batteries. When the batteries run out and I put in a fresh set (either NiMH rechargeables or, as a back up, Duracell AAs), sometimes the camera fails to pick up the fact the batteries are fresh, and continu...

bendy brickwork
But it's a round building ! If the brickwork didn't curve, it wouldn't meet round the back, and the building would be a wall !! :lol: ( sorry - I'll be serious now :) ) If you're using a CRT monitor, it could be that distorting the image. Try viewing a square grid graphic and check for lin...

I've a white balance problem - any ideas?
that's one setting that appears to be too tough for the camera to handle. I'd try to find a custom white balance setting that works. or even better a manual white balance off white paper (or grey card). next up: set camera to manual, take an exposure reading, then pop up the flash.using flash...

I've a white balance problem - any ideas?
To go back to the light source, fluorescent lights are a problem not because they flicker but because they do not have a continuous spectrum. There are gaps in the colour and therefore correction is difficult. Results on daylight settings tend to look green or yellow/green, very unpleasant. There...

T10 focusproblems
Hello Erikro, I don't own a T10 but from what you say I would guess that it is broken in some way. Unfortunately, repairs for digital cameras are usually unrealistic as they often cost more than simply replacing the camera with a new one. If you bought your T10 recently then it should be covered ...

DA* 16-50 Problem... :'(
I got my DA*16-50 out to take some photos this afternoon and was very worried to find that the SDM motor was not working at all. I had only used it two days before to take a few shots around Leeds and it had worked fine all day long then. I did test it for a good while... half pressed the shutter...

DA* 16-50 Problem... :'(
Tyr : I had a similar issue with mine (16-50) recently. It wasn't squeaking but the focus action was jerky and wouldn't focus at all :? I took it off and gave the contacts a clean but this had no effect. I then found the AF.S AF.C and MF switch was set in between the AF,C and MF settings. It...

DA* 16-50 Problem... :'(
Well, it is not squeaking anymore and it was not the AF lever as that was the first thing I checked. We'll see how it holds up. Over at DPreview a Nikon user had a similar problem with an SWM lens a few years back and it was the micromotor failing.

PEF conversion
Or........just use DNG in camera to start with.... ;) True Duncan, but as Rob stated, the DNG files are bigger and white balance is messed up. I use DNG's for archiving and after short experiments with the K20D DNG's I'm back to PEF's. Prieni
