k2000 shutter button not work sometimes
1. what lens do you use, what focus mode where you on and did it not take the photo or didn't it also not auto focus? 2. I think you should blame the batteries, what kind were you using? When temperature drops their performance drop as well and if the voltage is too low since you use rechargeabl...

k2000 shutter button not work sometimes
1: Is the firmware up to date? 2: Does this happen in any condition? Firm ware update for the first problem If the answer to 2 is yes then get back to the dealer and get it sorted under warranty. Get the warranty done first, just to be safe.

k2000 shutter button not work sometimes
Thank you all for the precise and direct questions, I didn't know what to put in my original msg. Here are answers to what I know/remember without looking at the camera: what lens do you use, what focus mode where you on and did it not take the photo or didn't it also not auto focus? the default tw...

k2000 shutter button not work sometimes
The shutter button won't do anything, and no power will be put to the lens, if the camera is in auto-focus mode but is unable to focus the lens because the subject is too close or does not have enough light or contrast for the camera to detect its distance. In this situation, focus on a different pa...

k2000 shutter button not work sometimes
I think you mean the DA18-55 and the DA50-200, am I correct? It doesn't really matter except for what Pete said but the lens should always try to get something infocus when pressing the button so does the lens try to get an focus lock, does the AF move the lens? The camera will only take an phot...

k2000 shutter button not work sometimes
I live in the UK but also own a K2000 (US version of the K-m) and on the odd occassion have had the same problem. I've found the problem most commonly occurs in low light or close up situations. Try changing it to manual focus, this sometimes overides the non-response problem.

Dioptre correction lens
Hi, My eyes have fairly bad astigmatism and being old I can also not focus on close objects. My understanding of the built in dioptre adjustment, K200D is that it compensates for close focusing and this works for me but I still can not get a crisp image of the focus screen markings. Has anyone...

Dioptre correction lens
It may be convenient for you to use your reading glasses to focus with older cameras. That can work out just about spot on. They will probably need to be dedicated reading glasses.

k200d and Pentax-M 28mm lens
Hi Peter. I recently tried one of these with my GX20. Very nice lens. Assuming this is an SMC-M, you need the camera in Manual exposure mode. The F-- will always remain because the camera has no way to communicate with the lens and find out what aperture it's set at. Use the aperture ring on th...

k200d and Pentax-M 28mm lens
Unless you've already done so, you might need to change a setting in the camera menus to allow use of the aperture ring on lenses (otherwise the camera won't work). The in focus beep/light can be a bit out - try to learn to use your own eyes to decide what's in focus. I've had much better result...

Trojons on SD Card
That would be safer, as CD wouldn't be able to be infected in the machine. But it would be a bit of a pain in the backside to burn a CD every time! Or you could just reformat the card every time you get it back from the photo shop. That will probably be safe enough, but you never know if the tro...

Trojons on SD Card
Why not use the switch on the card to set it to read only when you take it out of the camera? Just remember to switch it back before using it in the camera :D

Trojons on SD Card
It's a good idea and will probably work :) I would still be slightly wary though. Back in the dark ages 5.25" floppy disks used a notch system to prevent accidental overwriting (open notch = writing allowed, covered notch = writing forbidden), but you could buy disk drives which would ignore the not...

Trojons on SD Card
The other point that would be of interest to some is a follow on from Stefan's last posts. What are the file names reported as Trojans - but what is the program reporting them? Most anti-Virus (and similar)programs will tell you what it is they think that they have found, and some are known to rep...

M50f1.7 problem
Just reassambled my M50f1.7 and can't get it to focus properly ! It would seem I've replaced an element back to front, although I was being careful not to. :oops: Can anyone help ? maybe an exploded view showing element curvatures !? Please :) .

M50f1.7 problem
This is from memory ... Four elements in three groups. Front group is two elements together - convex face to the front. Center group - concave face to the rear. Rear group - convex face to the rear. The first quick check is whether it will focus to infinity - and with infinity somewhere nea...
