Kx infinity focus problem
In relation to this problem, IF the camera had an infinity focus issue, would this potentially add to the softness that these lenses display at long end? Or is it possible that the Kx ruthlessly exposes lens limitations fat beyond what the K100D would show? That could be it. Try some shots on a t...

Kx infinity focus problem
Are you manually turning the lens to infinity or automatically / manually focussing on the distant object? If the latter, try comparing auto focus on the subject, manual focus on the subject through the viewfinder and manual focus using live view (so you are focussing at the sensor). Kevin

Kx infinity focus problem
I also have a second Tammy 18-250mm with which I took another 4 shots of the radio tower earlier. This one had a better hit rate, with 1 sharp image, 2 reasonably well focused ones and one out of focus, all shot under the same conditions as before. Better, but not really good IMO... Than it looks li...

Kx infinity focus problem
My experience with the K10 did improve with the advice that John gave me a while ago. That was to use the AF button for the focus (yes centre point only) and then fire the shutter when the picture presents itself. (this is for football or group subjects). This combination of AF button and shutter ...

New K7 and my K10 bounces and lives
If the image looks shapr in the viewfinder and isn't on the sensor, then something is physically out of alignment. The mirror could be displaced or the focusing screen not seated correctly. If all is well, the manual focus image will be sharp and the viewfinder image will be sharp at the same time.

New K7 and my K10 bounces and lives
Given that we never had this opportunity to test AF in the film days, not without going to considerable trouble, and given that there will have to be a compromise AF setting as individual lenses will have different tolerances, do you think we are over-checking and over-correcting these days? Perf...

multiple exposure feature uses??
Take a three image multiple exposure. In the first shot use a red filter over the lens, a blue filter in the second shot and a green filter in the third. Anything that has remained still during all three shots will appear as normal (a combination of the R, G and B images) whereas items that have mov...

multiple exposure feature uses??
Nice effect no need for a filter though , you can simply extract the colour you need since the sensor is built up form red green and blue filters. Not "in-camera" on a K10 - none of those flashy colour extraction special effects here! :wink:

HELP!! Sudden noise problem with Kx
I think noise=snow in that photo because it's in a specific area and noise is all over the sensor, you don't see noise in the dark part of the tower point for example.

K7 HD Video
Well I was wondering if I could replace my S--Y digital handycam? It`s never been the same since they fitted a new sensor and my wife agrees too! Trouble is I have a K10 and K20. Cedric :lol:

Samsung GX. No . . .comeback. . ?
Samsung GX. No real prospect of comeback Friday 8th January 2010 Damien Demolder Samsung GX-10 1st prize With the launch of the new NX series of mirror-less cameras it seems there is very little chance now that Samsung will ever re-enter the DSLR market. Samsung UK's head of digital imaging, R...

Samsung GX. No . . .comeback. . ?
I'd imagine Samsung would make both cameras and lenses in-house, they certainly have the expertise from their digicam ranges so it's not a completely new area for them. I know a couple of people who own Samsung P&S cameras and they seem very impressed with them - these are non-photographers who view...

K20d batteries
I get through 1500 shots easily (and it's been 3000) with two batteries. Before an important shoot, they get charged. I don't use onboard flash, sensor shake is turned off. Li-Ions are better than NiMH at cold temps, too. I had my K10D in -10 for 2 hours today with one battery and 300 shots - no ...

K7 Review at The Register
I totally agree with the above comments, my Dad and I are both very happy with the performance of our K7's and feel it was money well spent upgrading from the K10D. Digital Photo magazine have done an image quality comparison table of metering, detail, skin tones and noise between the 3 cameras. The...

Pentax repair times
From my experience since Johnsons have taken over the repairs and the time the service has taken have not improved. For example SRS sent my K-7 off in August to have the sensor replaced due to it being damaged (I purchased it in July). A month or so later it had been sent back to SRS claiming th...

Camera comparison
I've gone 1-K20, 2-DS My reasoning is that I find my K10 resolves extremely fine features such as hair rather better than my *istDL2 does. The DL2 packs the same sensor as the DS, and picture 2 looks as I would expect output from my DL2 to look. Both look really good though, and as said above...

Hmm. Fullframe with the sensor from alpha 850? would be nice... Bret

K-7 now £799!!
Maybe a K-7 mk2 with a high resolution version of the sensor that is inside the K-x. People are actually buying the K-x over the K-7 now because of the superiour high iso performance.

K-7 now £799!!
With the K-7 you get micro focus adjustment, weather sealing, 100% viewfinder, more fps, another wheel, top lcd and probably a few other things that (to me) justify the price difference. My complaint is the noisier sensor.
