K10D / 21mmDA auto focus defect.
Viewfinder, I've ventured into the arena of AF lately as my eyes are not what they usta was. Know what's frustrating? Most of the situations that fool my eyes also fool the AF. Very wide angle lenses always seem to be in focus, and I'm not surprised a 21mm can fool the K10D, they ALWAYS foo...

K10D / 21mmDA auto focus defect.
I suggest that the camera is set to centre-spot only focusing, otherwise madness ensues as the camera tries to guess which focusing point to use. Then you can focus, hold with a half pressure and recompose before taking the shot. I find it works most of the time. If it doesn't, try focusing on so...

K10D / 21mmDA auto focus defect.
That article makes no sense at all. I suspect, as JR was implying, that the people who are having problems with the lens are using the camera with the AF point set to Auto. G

K10D / 21mmDA auto focus defect.
I'm finding that the more experienced I become as a photographer, the less I use auto-focus. I don't know if that means I am taking better pictures, though. ;-)

K10D / 21mmDA auto focus defect.
talking of manual focus, I note that the K10D has interchangable screens but that neither of the option screens available from Pentax has any sort of manual focus aid Does anyone know if you can get a split screen focus aid screen from any 3rd party? also when they say the screens can be changed,...

K10D / 21mmDA auto focus defect.
The K10 screens are apparently readily interchangeable by the user. The 'Ist' camera screens were available from independant makers, notably 'Haoda' and 'Katz-eye' so it is highly likely that they will be, or already are, available for K10D. Both these screens offer a split image rangefinder a...

K10D / 21mmDA auto focus defect.
But there are warnings on that site that metering will be affected under some circumstances unless you opt for their "optibrite" treatment.

K10D / 21mmDA auto focus defect.
mmm indeed, I read the write up in full and it does not recommend using spot metering with a lens darker than F2, though it claims pattern and centre weighted modes are unaffected to at least F5.6 I've always wanted a DSLR with a split screen, but I'm not sure if I'm willing to trade spot meterin...

K10D / 21mmDA auto focus defect.
I see the same with my DS and the 16-45 and 50-200. At the far ends of the focal lengths the camera has some difficulties focussing. Just like something I posted a time ago, just check the line on autofocus. "Auto Focus - won't"

K10D / 21mmDA auto focus defect.
My DS "hunts" a bit, particularly if the object is quite distant (over 50 metres), the K10D is much better in this respect! :)

K10D - Infrared performance?
I wasn't aware that either camera was capable if IR pics, is there a specific mode or trick with the camera, or are we just talking about adjusting images in photoshop. I have had good IR results from the *istD which is why I asked the question. You do need to compose and focus the shot before fi...

K10D - Infrared performance?
Some manufacturers, Canon particularly, filter out IR light very aggressively. My *istDS does respond quite well to using a Hoya R72 filter. The filter is opaque so it is necessary to focus first and then fit the filter, although you can point the camera and guess! Don't forget to alter the focus...

K10D - Infrared performance?
There was an instance very recently of one class camera being released with an ineffective IR filter. It had the effect of causing many dark or black items to have a magenta colour cast :oops: . The company in question is offering a free "Upgrade" (correction) and (I think or was it OR) fr...

K10D - Infrared performance?
Back to the subject of metering, with the DS (haven't had a chnace to try it with the K10D) I found the metering to be reasonably accurate, and after a while you could get a feel for how much compensation to use. But as John says - bracket! Or at least start from the exposure time suggested by the...

K10D - Infrared performance?
I have had an initial try with the 10D and the results are not good. I have had some superb resilts from my D and was hoping for similar from the 10D but not so I,afraid. Back in the dark age I used to carry two camera bodies when out and about the Z1 with colour slide film and an old ME Super with...

K10D- Auto EV Compensation, plus Auto ISO in P
Actually, just to add to that: * You can Tv shift to a slower speed, step by step, but you can't then shift back to the Tv/Av combination you were at. (i.e. the K10D allows you to reduce the ISO in Hypershift, but not increase it). Also worthy of note (compared to the *ist-D) is that if you enab...
