K-7 : help with dust
I have always been advised against using brush type sensor cleaners by my local Camera shop as they can shed bristles which can get lodged within the Camera. I have used the Pentax Sensor Cleaning kit successfully for 3 years now and have used it on my K7 several times. Available from SRS. Regar...

K-7 : help with dust
Actually the Camera shop did not stock the Pentax Cleaning Kit or the identical Nikon one.They actually cleaned my sensor for free using some relatively cheap swabs (£17.50 for 10) and a cleaner that smelled like Methylated spirit. Brushes do lose bristles! I am a painter so i know only too well! E...

K-7 : help with dust
I had an episode with dust not long ago. It had got suddenly much worse, so much so that I was avoiding taking pictures. I got an Arctic Butterfly, and it was completely ineffective. Then I got some fluid and swabs from , and the results were quite good. You can see some before and after ...

K-7 : help with dust
Another useful piece of kit is a home-made Vacuum cleaner, All you need is a cheap electric tyre inflator (Around a fiver) or a Compressor and some plastic tubing and connectors from a pet shop Aquarium store. It works a treat for cleaning the nooks and crannies inside the Camera. Just around a me...

The sound of sensor shaking
Hi All I've noticed that my KX makes far less noise when it does its start up sensor shake compared to my K10D. Is this normal? I asked to listen to a friend's KM and it is also very quiet during the sensor shake. Can anyone say if the quieter shake means that the dust won't be removed...

The sound of sensor shaking
The K-7's sensor shake is almost inaudible as it's done at an ultra high frequency. This is supposed to be more effective than the K10/20D's low frequency shake. I would expect similar for the K-x and K-m, although I haven't listened to them myself.

Is the Pentax a Pro System?
I'm not sure what the definition of a "pro system" would be. Full frame? People are able to make good money with a well-handled APS-C sensor DSLR. A good selection of lenses? Pentax's back catalogue extends from 1975 if you stick to K mount lenses. As I've said before, I get the distinct impress...

What have Pentax been up to?
The K-7 is noisier than the K10D at medium and high ISO settings. Remember that the images in this thread are downsized and have had some NR applied. You can see distinct noise when you look at K-7 RAW ISO 400 images at full size with no NR. That's with the latest firmware as well. First set h...

New entry level model coming soon?
Went to LCE this afternoon to have a peek at the K-7 and K-x. Both very desirable cameras! I asked the salesman about rumours of a k7 with the new sensor they are using in the K.x. He said the only new Pentax he was aware of was something BELOW the K-x.

New entry level model coming soon?
It was Leamington. Stefan, we were specifically taking about DSLRs But the 645D is a DSLR but a mid-format instead of an APS-C, same camera different size of sensor. If he doesn't know about the 645D then I wouldn't trust it :wink: Isn't the 645D Japan only, at least initially? Yeah forgot about ...

Pentax K-5?
It's not a camera above the K-x that people should be concerned about, it's below the K-x that needs attention. I strongly disagree. The Kx is by all accounts doing relatively well as the entry level product to the Pentax ‘range’. On the other hand, with apologies to K7 owners it is an open secr...

Pentax K-5?
On the other hand, with apologies to K7 owners it is an open secret that its sensor is inferior to that in the Kx. Not at low ISO, even my K10D preforms better there then the K-X :wink:

Pentax K-5?
The more I think about this the more I wonder if the size of the mount has anything to do with it. Surely it is all dependent on the size of the front element and the amount of light getting into the lens? And the mount has no effect? Well just measured it and it's 45mm if you don't believe me m...

Pentax K-5?
I doubt the numbers for individual cameras are far off, but I don't think many worthwhile conclusions can be drawn from such an ineptly constructed figure. The only reason I used that was to show that not the lowest entry level models but those a step above are sold better, making it for me question...

Pentax K-5?
Streamlining usually means cutting down and I'm not sure this is what the posters actually mean. :?: To clarify, what I mean by a streamlined product range is one were there is a clearly defined ratcheting up of features in models along with price; objectively and subjectively that includes sensor c...

Pentax K-5?
Shaky just some points. I at least rather have a good ISO 100 or better yet ISO 50 then a clean ISO 1600, it seems I'm one of the view that thinks that way but I'm sure some studio shooters agree with me. One of the reasons I haven't upgraded, the lower ISO aren't as good as those on the K10D. Y...

How about a brave move and produce a true photography student digital camera - a sort of digital Pentax MX. My ideal spec would be as follows: -Full frame sensor with dust control -Manual (and possibly Aperture Priority) only -Spot metering and Centre Weighted -Depth of Field Preview -Manu...
