Thanks Kim! Now of course the question is do I put it back on ebay, or do I find a Spotmatic to fit it :roll:

Dodgy K10D?
I think it's using the flash as an auto-focus assist lamp. It's in the manual somewhere, and it doesn't happen very often. Robin

I think it's using the flash as an auto-focus assist lamp. It's in the manual somewhere, and it doesn't happen very often. Robin Sounds quite right - It happens in dark situations and is more likely to happen with the kit lens. Did it fire the shot? Was it dark?

Trying to find something in the pdf of the manual. Actually, I can't find anything about it in the manual! Think it must have been there in the *ist-D manual... maybe they forgot for the K10D. But, yes, that's exactly what it is - a focus assist. And yes, it makes a terrible noise! If you have ...

Chris, so it is! :oops: • In |AF.S| (Single mode), press the shutter release button halfway. The built-in flash will discharge automatically several times, enabling the autofocus to focus on the subject easier if the subject is in a dark area and the built-in flash is available. And I agree - i...

K10D focus
Just thought I'd share my little experience here... Having used the K10D for a year now, there were situations where it just wasn't getting the shot I'd imagined. Particularly with the 12-24 I wasn't getting the clarity I'd have expected, which was a real shame. I took a little run with the trus...

I posted my similar problem awhile back and LCE ended up replacing the camera. I'm amazed you could fix it yourself, good on ye.

Hi Matt Just completed the tests as suggested in Tim Jackson's document, looks like I may have some front focus issues with the FA50 f1.4 @ f1.4 and maybe f2 also. I would appreciate your comments/thoughts, I've uploaded the test shots here....

Having looked at your results, I would say that you do not have a problem. If I get half a chance, I will upload a couple of pics of what the problem is when a lens truly back focuses! Kim

K10D focus
Found similar issues a while back. I had uploaded a pic of the sensor arrangement on my camera. I was a tad surprised at the size and arrangement of the sensors. It turned out that the center of focusing sensors on my K10D is not exactly in the center of the focus screen. I now focus at the l...

Brian - viewing those shots I dont think you did this: 5. When shooting your test pics, you need to be close enough that the test chart somewhat more than fills the frame. Get nice and close. I can see a lot of "non-white" in your shots (table).....this might help as well.

K10D focus
Brian, Your tests look just fine. Although there may be a way to calibrate a single lens - I don't know how to do it. My problem was consistent, repeatable, and across-the-board back-focus. And, Peter, I didn't have it absolutely square either - that's not the point. The point is that (1) ther...

Thanks for the replies guy's, I only saw a problem in the first shot with the FA50 at f1.4 but on reflection it appears that my center focus point is more to the bottom of the circle, like amoringello's. The last bunch of FA50 shots was just a quick burst at different apertures. One thing I did not...

Right, I've read through this thread a few times - I'm being thick and missing something! What actually is causing the problem? I can see that the camera is focusing behind where you want but is this a lens problem or a sensor alignment problem or what? My paranoia knows no bounds so I've downloade...

Ken, My K10D focus was off. All my lenses backfocussed. Everything was only really in focus if I used a small aperture. The tweak was to bring the camera's AF system more into line with reality ;) As I said, it was more noticeable with the 50mm at f/1.4 (and for a long time I thought it was me ...

So, is that a digital tweak (hack the firmware) or a mechanical tweak (adjust the focussing mirror)? Whichever, does it void the warranty?

So, is that a digital tweak (hack the firmware) or a mechanical tweak (adjust the focussing mirror)? Whichever, does it void the warranty? Mechanical tweaks are a seriously bad idea. AFAIK there is a complex AF table that has to be initialised on a special test-bed. Trip back to Japan for that I ...
