Pentax K-7 Flash Problems
in manual the iso is only selectable, and taking pics of my kids indoors i need fast shutters speeds hench flash with 180/sec speeds and if i drop the apature more in those modes it will over expose more, just seems abit flawed, my k20d i never had this problem, In what mode, flash and camera??? If...

Focus adustment on a K10D
Thanks, John. My question was meant as a response to Stefan's statement above, because I thought the difference would be negligible, if any. I've no idea how much it differs, at least Pentax and others find it enough to make a special sensor to adjust the AF sensor to the light. The way it works ...

KM Sensor / CCD mark...??
Hi all, I've recently taken quite a few shots with my KM on a trip away and on reviewing them back home I seem to have a mark on all of them..... Its not the lens as it appears when I used either my 18-55 or 75-300 lens so I can only assume its the sensor/CCD glass ? It doesn't appear to be...

KM Sensor / CCD mark...??
to get a better look at it, point your camera at the sky or something else bright but uniform, stop the lens right down and take a shot. I often like to set the focus to minimum and use the ceiling. Doesn't matter if the exposure is a bit long, the thing you're trying to image is on the sensor so ca...

KM Sensor / CCD mark...??
Try the Arctic Butterfly brush first before going on to wet cleaners. It will almost certainly do the trick. You could also consider the Pentax sensor cleaning kit. Tbh if it were mine I would just Photoshop that out for a while, and only clean the sensor when more appear, or I am sick of cloni...

KM Sensor / CCD mark...??
You might try activating the sensor cleaner a few times. On Saturday I noticed several horrid little blotches in my skies which I had to clone out. I try hard to keep it clean, blowing the rear elements with an air blower before fitting, but I use so many cheap old lenses they must have loads of...

KM Sensor / CCD mark...??
It looks like your run-of-the-mill dust spot to me. The Artic Butterfly or the Pentax O-ICK1 sensor cleaning kit will deal with it. I never tire of that part number, someone at Pentax has a sense of humour after all. Meanwhile the heal tool while get rid of it. K.

Just say "ohh ick" and curl your nose up and you get the basic idea! ;)

Shim replacement works on K-7!
Hi all. For those that followed my thread regarding the Katz Eye focus screen and the issue of the shim, I have received my set of shims and am happy to report that the shim replacement seems to have worked correctly. I have only done preliminary testing, but a .20mm shim seems to be about right...

K100D focus screen change
Hi Ken, I'm afraid I do not understand, the frosted top surface of the screen is forced up against the base of the prism by the carrier frame, if the surfaces touch or are separated by the spacer how can the thickness prevent it "sitting against the prism" even if the screen was 5mm thick the top...

K100D not working
Hi Errol, The K100D is about 2 years older than the K20D and its features are so much better. Its sensor is CMOS compared to the K100D's CCD. THe K20D runs on a lithium battery and it can last for almost 1500 frames on my usage (without flash). Price wise I am no help as I am from Singapore ...

New K7 ??? or not ?
My tuppence' worth: * Quieter shutter. A plus for show & theatre work! * Better exposure in low light. The new 77 point metering does seem mightily improved in dim lighting conditions (and flash too). * Better WB. Again, in dim lighting conditions this is really helpful. * More useful live vie...

Sensor noise?
Following up on Mannesty's comments to my Full Moon picture in the Your Photos section, I began to wonder if there might be a fault in the sensor. I made a couple of test shots with the lens cap on, on both the K200D and the K20D. Images are 100% crops at 600x600 pixels. K200D noise: K20D ...

Sensor noise?
Hi Terry, Taking a shot with the lens cap on could give very misleading results as you cannot asses when you have attained a correct exposure. Perhaps if you provided the ISO and exposure settings that you used might shed a little more...

Sensor noise?
I see what you mean, Pete, I was merely trying to take pictures of a "dark" area. Both images at ISO 200, 1/180, one at f/16 the other at f/11.

[quote:3496ace15f="terje-l"]I see what you mean, Pete, I was merely trying to take pictures of a "dark" area. Well you sure did that, You could`nt get much darker than that! (unless you stood in a cupboard at night with the light off when you took the photo with the lens cap on!):D Regards - P...

Sensor noise?
To be serious though, You really need to take a correctly exposed image of a subject and assess the noise from that. My normal Night shots are taken at 100 ISO and beginning around 30 minutes after sunset using around 20 seconds at F18 and usually continuing until i can no longer see any light in th...

Sensor noise?
You should make two photos because you've different types of noise and if you can see if it's random or not tells a big deal.
