Help needed regarding K7 - RAW PEF and Elements
Actually you got a point there I do my editing in CS4 and that uses Camera raw which sees the files.. I only use Elements for Cataloging - I shall try bridge and see if it works in there if so I shall have to start getting used to using Bridge instead of elements .. Really Elements is wasted on my P...

K-x v K10
One of the frustrating things about my K10 has been its performance in low light, at high ISO. While it has been demonstrated on PU that a K10 can take less noisy images when properly exposed, I perhaps haven't been as skilled or as fortunate. I was asked to shoot the rehearsal of some orchest...

Focus adjustment - again
Has anybody found a relationship between the +/- 10 steps in the Custom Menu and the um values in the Debug focus adjustment? Having one manual lens (Pentax-A 1.7/50) I was thinking of adjusting this lens using Debug, and compensate the other lenses using the Custom Menu. Assuming that the Deb...

The Pentax-A 1.7/50 is a manual focus lens. Focus adjustment is for AF lenses. If your manual focus lenses are FF/BF, then you need to adjust your focussing screen with shims.

The Pentax-A 1.7/50 is a manual focus lens. Focus adjustment is for AF lenses. If your manual focus lenses are FF/BF, then you need to adjust your focussing screen with shims. Disagree focus adjustment is a perfectly normal thing for manual focus lenses. Focus is OK when green hexagon is lit...

Thanks for the clarification, Bob. This is also my understanding. And the green hexagon is very helpful also with manual lenses, especially when wearing spectacles. Do you agree to my assumption that the Debug mode provides a basic adjustment, and than the Custom menu provides offsets from the ba...

Focus adjustment - again
Do you agree to my assumption that the Debug mode provides a basic adjustment, and than the Custom menu provides offsets from the basic setting? yes, with the reservation that I haven't tried it! Don't forget that on the K20D there is an 'all lens' adjustment in the menu which will apply to any l...

Thanks, Bob My original question still remains, though. What is the relation between the +/- steps in the Custom Settings menu (item 35) and the um (micrometres) scale in the Debug Mode? I am referring to the K20D in both cases.

Focus adjustments apply small corrections to the autofocus system. A manual focus lens does not make use of the autofocus mechanism. yes it does! :) You can have the AF active while you manual focus and it give you a signal when the AF thinks the lens is in focus. Also with the rest of your com...

Hi Stefan, That's exactly what Dick said, each one is adjusted independently :) so that they agree with one another. Greg

You sure Greg, looks to me Dick was comparing the focus indication of the AF with his focusing screen. He never talked about the focus of his photos and that's what's all about.

No, how can one ever be sure about anything, it's all subject to interpretation. Maybe I read it the way I wanted to understand it. :D Greg

Focus adjustments apply small corrections to the autofocus system. A manual focus lens does not make use of the autofocus mechanism. But the green hexagon does, it confirms focus, even when using a manual lens. Therefore I find it useful to calibrate AF also for manual lenses.

Focus adjustment - again
When you don't have a Katz Eye, and your own eyes are not what they used to be, I find it easier to focus manually with the assistance of the autofocus system, i.e. the green hexagon focus confirmation. For that to work one needs to calibrate the AF system.

K-x problem at 1/125th
There are four normal causes of blur that I can think of: - inaccurate focus - insufficient depth of field - camera movement - subject movement If it's none of these, then there is something wrong with the camera and/or lens. I take it you've tested carefully using tripod and delayed rel...

K-x problem at 1/125th
Hi Mecrox Just wondering if problem still exists on your K-x? You got me all paranoid so I started checking all shots taken at 1/125 and they do have a distinct blur. This is despite taking them shots with a new set of lithium batteries. I wonder if there's a quick fix to this since I'm reluctant t...

Oh no. New cam. First DSLR. Probs. Second hand cam ?
When I bought my Samsung GX-20 (Pentax K20D clone) it arrived with the sensor covered in dust spots. Since the camera was only recently released at that time I doubt I got a returned camera. I tried the camera dust shake mechanism but that did not help. I then used a rocket blower but a lot of du...

As far as the shutter count goes, most cameras have a couple of hundred activations from testing (I can't remember how many my K20D had, I'll dig out the shutter count on my first shot). However this normally doesn't show in filenames (ie you only discover it by using Photome). Double-check wheth...
