whats the deal with the Shake reduction
It's been alleged that leaving it switched on, on a tripod, fools it into shaking the sensor when the camera isn't being shaken, thus resulting in worse results than if it was switched off. I've never seen any evidence for this myself, nor seen any presented. I must try a really long exposure so...

EV compensation - just a trick?
I find my K10D under-exposes. I think this is a common 'complaint' and possibly based on trying to emulate film or specifically slide behaviour? is this true? I am going to have to compensate with the EV dial. Does anyone know if this just amplifies the signal or if it actually changes the setting...

aghhh crap !!!
It's probably just dust inside the main chamber. Get a "Rocket Blower" and a soft brush. A full clean (as quoted) is pretty time consuming and will include disassembly and internal cleaning. Try the blower first! (And don't use compressed air, or worse - blow it with your mouth!) ...

K10D Faulty Flash
The pop-up flash will always issue two flashes. You might not always see the two, but there are definitely two. If you want a slave flash, then you have two options: 1) Buy a P-TTL compatible flash (like the AF360 or AF540 from Pentax) 2) Get a digital slave adapter that can ignore the preflash. ...

flash lead
Matt, I was assuming (wrongly) that the OP had acquired a flash unit compatible with the K10D. Your reference to 5p kit reinforced that misapprehension. On re-reading, I see that he in fact bought the much earlier 240Z, which not only doesn't have a 5p socket, or even a 4p socket, but can onl...

Should I buy a K10D now or wait?
Thanks everyone. If the new Pentax model is going to be a lot more expensive, the only thing that might tempt me would be a full frame sensor in it ... and considering Pentax's commitment to their special digital lenses, this seems pretty unlikely right??

Should I buy a K10D now or wait?
Correct ;) And a full frame sensor DSLR I would expect to be in the region of £1500+ anyway. There's rumour of a larger sensor, but not full frame. Maybe a 1.3 crop (rather than 1.5) but who knows...? As the proverb goes... "The farmer who watches the clouds will never reap" ;) Matt

Should I buy a K10D now or wait?
Would the DA image circle still be Ok at 1.3? I seem to remember Matt doing a test with the 16-45mm when it was new, to see how it fared on full frame. It wasn't at all bad as I recall, so 1.3x might be OK for at least some of the lenses. It would be interesting indeed if it turned out that they ...

It would be interesting indeed if it turned out that they were all designed for a 1.3x crop sensor. That's not likely John. I see a tiny amount of Vignetting from my DA 12-24mm, and a bit more from my DA* 16-50mm. The DA* 50-135mm seems good though.

K20D?
I read on another forum the probable specs of the probable new Pentax -the K20D. they are: 14MP Pentax designed CMOS APS-H sensor Faster autofocus better antishake 4 photos per second 3"screen Live view. Now I know it is all speculation at th moment, but would you buy one? Why do we...

K20D?
APS-H was (on APS film cameras) approx 30mm x 16mm, so a bit more 'widescreen' than the current APS-C sized sensor in the current Pentax DSLRs (24 x 16). Dan

K20D?
I read on another forum the probable specs of the probable new Pentax -the K20D. they are: 14MP Pentax designed CMOS APS-H sensor unlikely, since it wouldn't work with DA lenses, and you'd be cropping it to 3:2 most of the time anyway so no real resolution boost over the K10D Faster autofocu...

APS-H was (on APS film cameras) approx 30mm x 16mm, so a bit more 'widescreen' than the current APS-C sized sensor in the current Pentax DSLRs (24 x 16). You sure about this, Dan? it's another 3:2 format - about a 1.25 factor compared with 35mm, rather than 1.5 for APS-C.

K20D?
14MP Pentax designed CMOS APS-H sensor This would be worth having if it also came with significantly higher, low noise ISO settings. Otherwise it's only a marginal increase - it would have to be nearly 17 MP for it to be the same proportion more than the K10D, than the K10D is more than the K10...

stocking fillers
Any hot tips for inexpensive ways to have even more fun with a K10D? I am being pestered for Christmas list by my nearest and dearest. Could be worse I guess. :D I am thinking... remote control (or soldering iron and a bit of wire) flash (no idea which one) gorilla pod (big one) Sensor clean...

Pentax K20D
The new sensor will be a Pentax/Samsung sensor - Nikon have the rights to the Sony sensor - they can't even use it in their own Alphas. The camera has already been discussed under the same title earlier, in the same forum ;)

Pentax K20D
Sigma has a 14MP sensor in their DSLR, perhaps it could be that?
