When i turn on the camera, it acts correctly, but when i try to take a pic, the lense focuses in and out, and then tells me to turn the camera off and back on. This thing is less than a year old, and i have taken good care of it. any ideas?
Ive had it off for several weeks, with the hope that the internal battery would reset itsself, but to no avail :(
I'm having the same problem. I turn my camera on and it stays on for a minute and then says turn camera off and then on again. The shutter does not open.I'm having the same problem.

Some combination of repeated on/off cycling, manually holding the lens in upon restart, and a gently rapping the camera against my desk solved the problem for me.
It's my understanding that a speck of dust or dirt gets stuck in the zoom mechanism and the camera needs some "help" to get it cleared.

Although you think the lens is in focus, when stopped down, I know it is not.
There are enough articles that tell about Depth Of Field, but I give a short explanation.
The DOF from a 50 mm lens on a APS-C camera, when set to f /1,4. when you focus on 1 meter, is just 2 cm when on f /4 you have a totoal of 6 cm and on f /11 it is 11cm. So wen your camera / lens combination has a back focus of about 5 cm, it will come within the 11 cm you get in f /11. Still the picture is not in focus, but you see what you want to see sharp.
I searched through the complete manual, scanned the review on Dpreview and searched the site from Richo, but noting to find about correcting back or front focus. on the K10D. Perhaps, because in the days this camera came on the market, they thought the photographer who uses f /1.4 lenses is used with manual focus.
I'm, not sure, but perhaps someone on the Richo / Pentax service centre can tell you, if they can correct the setting for your lens.
To my experience, the front or back focus is in the camera. (the six or 7 lenses I use on my camera, all have the same back focus, but my Nikon has a setting to correct that.
So if you want to use your lens without any change made to your camera, there is only one option, focus manually.
If you placed the lens correct, till it clicked while turning, it should work correct. Did you check if there was anything on the contacts, before placing the lens?
Can you focus manually? and is your camera in the auto focus mode?
I can't make more at this moment. Success.
I have a 5D Mark II that has acted up like this. 99% of the time it will reset itself it you power off, remove the lense and allow them to sync up. Try this, it may work for you too!
It sounds like the lens isn't properly compatible with your camera which can be common on third party lenses. You can either set the lense and the camera to manual focus and focus the images by hand or sell the lens and find one that works in auto mode with your camera.
i try to turn the camera...but it seems that hangup,,,,the lights green it blinks blinks,,,,and theres a circle on scren.....i have lotsof pic there that is very important for school...was it gone?waht can i do so that my pic wont lost?pls help..
Usually this is a lens fault as the focusing gear is all in the lens. Clicking sounds as if a rear pinion has cracked. It's not uncomon in the 'prosumer' level lenses where plastic gears are used a lot.
It's just possible the fault is which the auto-manual switch. This usually has a mechanical clutch coupled to it which physically disconnects the gearbox from the focusing ring, as well as operating a switch to tell the camera to turn off the AF system.
There is no battery in the lens. The lens receives power from the camera. Whether or not the lens is getting power, though, you should be able to focus manually.
When you say you can't focus manually, do you mean that you can't turn the focusing ring on the lens, or that when you turn the ring the image does not come into focus?
If you decide the lens needs to be repaired, I recommend sending it to Canon. You can go to their website (canonusa.com if you're in the US), click on support, and follow the links.
I'm having the same problem. I turn my camera on and it stays on for a minute and then says turn camera off and then on again. The shutter does not open.
