K200D SR (Internal Movement)
The SR system makes sound when you tilt the camera, that is correct. There is allso a orientation sensor which detects if you are holding the camera horizontal or vertical.

The K7 price is making me want to buy the K20D !!
FF is arguably cutting edge for '35mm DSLRs' so pentax either joins the fight or turns it's face to the wall......there IS no in between ground. If by "FF" you mean the 36x24mm format (and I guess you do) then how can anything based on a 100+ year old set of measurements possibly be described as "cu...

Yes sony isn't selling their FF cameras to well, they don't get a reall good footing in their. Maybe when Sony and Milota users might go more pro over the cmoing years that they sell more of them but at the moment not. Most will go to Nikon and Canon since those are consider the profesional brand b...

I'm all for the square sensor format, preferably based on a APS-C base format (take the long side of a APS-C sensor and make it into a square). This way we could keep using our existing lenses since the image circle will be large enough but you get larger area covered then with a APS-C sensor. The...

I have a K20D...I really like it. I bought Pentax more or less purely for the advantage of small size & weight...ie K20D with Ltd lenses. The D300, 40D, 50D etc are all too large IMO. However, the ONE thing I do not get with the K20D (or K-7) which I would VERY much like is a decent size viewfind...

Distracting line
Hello, I've got following problem with my K100D. There are some hot pixels on my sensor, but that's not the main problem. There's distracting line in upper part of picture. This occurs when photographing in ISO 3200 or 1600 at night. It looks like "line of increased noise" in picture. My questi...

Thordell: The hair has to be pretty straight and aligned on the sensor :D Yes, you are right, hot pixels are not visible on this picture. ttk: Of course, image is crop. Picture was originally taken to RAW format. Thank you for your comments.

Distracting line
Banding, not really uncomming I believe or is it something else? :? Banding noise is highly camera-dependent, and is noise which is introduced by the camera when it reads data from the digital sensor. Banding noise is most visible at high ISO speeds and in the shadows, or when an image has been ...

GX-20 Price
in which case how can the camera do more than ACR et al? It can't of course, as you imply. The RAW file is data straight from the sensor, the same data that the camera works with. RAW simply gives you the opportunity to adjust the root parameters (white balance, sharpening etc) to your preferences r...

Samsung here forever?
Do you think Samsung will be around in 10yrs to come? Also do you think they will bring their version of the K7 out? I do believe that Samsung made the sensor for the K-7 for Pentax so hopefully yes they will be around for a while yet.:wink:

K-7 at Iso 1600 (warning, large file)
Here is a crop from a JPEG direct from my K20D. ISO1600 highest quality JPEG without any noise reduction (turned off in custom menu). I used the lossless crop option in Irfanview to crop the image without quality loss. I find the K20D allready very good in the noise department. The decidin...

CLEANING ?
Hi guys, I've been using my K10 almost daily since I got it and each time I must change the lens 2 or 3 times. The camera itself is out with me in all kinds of weather and with the lens changing I think it's only a matter of time before I need to clean things up. I use the dust and sensor cleaning ...

CLEANING ?
It's a topic dicuss many times, maybe we should make a complete list of tools and ways and make it a sticky. If someone is willing to write a short articale about it that would be great, you'll have my support. To answer you question Deryn. It's why you bought a DSLR to begin with, that you can ...

CLEANING ?
Hi Stefan thanks for the explanation, very comprehensive. I'll search the forum for past topics as well. As I said I've no problem at the moment but I want to be prepared. Thanks again, DERYN

CLEANING ?
You think you don't have a problem :wink: set the lens to the highest f-number and take a shot of a blank wall bit over exposed, the photo doesn't have to be in focus. When you look at the photo all the dust and particals on the sensor show up.

CLEANING ?
I find that when using a puffer like the Rocket blower it helps to have the lens mouth pointing downwards. It is a bit awkward to do but most of the dust falls out of the camera instead of further into it. I am not convinced by the sticky pad things like the Pentax O-ICK1. I had a couple of mar...

Yes and the electronic shutter reset the sensor.

Yes and the electronic shutter reset the sensor. Obviously, but you were talking about wearing your gear down and mechanical shutters, not the electronic one! :D
