K-5 Liveview focus looks impressive
Apologies if this has been posted already... This video of the K-5 performing AF in liveview is very impressive. Ok, granted here's lots of light on the subject, but the extremely adjustable af target point & speed of the contrst detect system is very promising indeed. As I said on another thre...

Focusing screens
Hi everyone, Having upgraded to a Pentax Kx from the older Pentax SLRs, I find that the manual focus on the K-x is a real pain in the butt! Thinking of selling and getting a Pentax dSLR with a split screen, that is of course if there is one available. Can anyone point me to the right buy, please? ...

Split focus screen for K100D adventure
to modify a focussing screen to put in the K100D went rather well. Here I am ready to do another one. Thought I would try for a diagonal split as the screen is big enough to rotate before the fatal trimming. The donor this time is a super program that has seen better days. First issue is the bli...

Split focus screen for K100D adventure
I'll probably try scoring the glue down with a scalpel first. Want to avoid twisting or levering as the 30 yo acrylic splits easily. Pete

Split focus screen for K100D adventure
Yep the scoring went well and soon the screen eased out of the frame.

Split focus screen for K100D adventure
Ok the screen is taped up and ready to check the 45 degree plan. mmm good in theory but not enough oversize to get a 1/4 rotate... Is it worth it ?

Split focus screen for K100D adventure
I decide not, so the marking out and sanding down will be next :) bit of a shame but the split is going to be so welcome, I don't mind it being horizontal :) As you can see the tab on my first attempt was pretty rough. Will attempt a tidier job. The old belt sander is an order of magnitude too ...

Split focus screen for K100D adventure
Progress is slow as I contemplate which woodworking tool I can go at this with :D Noticed it seems thicker than the standard screen. Might have to leave out the shim which might lead to 'issues'. Will have to wait and see. Sort of sad to see how much view area we lose with DSLR Pete

How long til I can get a used Kx for c. £200?
cabstar yeah I know i watched it. you did well selling it last week. Last week that was a good price for both parties as a new one at srs cost £379. Yesterday a new one cost £329 at srs so once those prices get known surely no-one will pay £300 for a second hand one. If we work on the ...

gx10
the original Pentax auto focus system used a motor in the camera with a mechanical link to the lens. Newer Pentax lenses and some third party use a motor in the lens with contacts between camera and lens for control this is called Sonic Motor Drive or Hyper Sonic Motor (or somthing like, Stephan kno...

gx10
Its worth mentioning the GX10 is a lot higher spec camera than the K100 and is classed as a Semi-Pro model as opposed to the K100's Entry Level. You will find the GX10 a lot more versatile in the way it operates. Kens right about SDM (HSM) lenses, at this point its not really worth considering...

camera shop in London near Knightsbridge with fixed aperture zoom lenses?
Thanks for the replies so far. I'm over with my mum Fri night late, wedding is Saturday afternoon and we're gone Sunday morning. That's why I want somewhere as close as possible- won't have a 1/2 day out and about. Being honest I'm going looking as much for research as to buy. If I'm very happy wi...

K7 Battery Depleted
I have a K7, It is about 3 weeks old. While I was out last night the indicator in the LCD screen showed full battery power, however when I used Liveview I managed one photo then the Battery Depleted message appeared and the camera turned itself off. I could turn the camera back on and use it withou...

K7 Battery Depleted
does not sound right to me, right the battery was full but when you used liev view it managed 1 shot then turned off, what was the battery indicator saying when you turned back on.

K7 Battery Depleted
Same issue on dpreview forum: Seems the battery life indicator is not the most accurate! Me, I just shrugged and carried on without LV and movie mode. After the behaviour of my K200d, this actually seemed like a blessing, as the K200D would run out of power with virtually no warning sometimes. ...

K7 Battery Depleted
I think with everything running there is quite a drain on the battery (even though they have little internal resistance) so the voltage will drop. The sensors basically measure the voltage and guess what's left in the tank. So with live view going, the sensor going, the AF motor going etc lots o...

What microphone for video?
every type of mic has it's pros and cons. noise cancelling mics are probably best avoided for most novices. here is why.. expense, and quality... for some types of eng or environments they are fine. But with either electronic trickery or out of phase dual mics the noise canclling cons are lower...

Oh my, I just read that "review" you linked to. What a joke. "the built-in speaker on the back that lets you listen back to recordings without having to plug in a pair of headphones, demonstrate that Zoom's designers really did their homework designing the H4n" A speaker? First, every shoulder...
