K20D focus mode switch, opinions sought.

Hi Greytop, My K20 is silent, What lens does this happen with? It may be a mismatch with the lens I did have one lens that was very faulty on the mount, the alignment was wrong with the drive screw.:?

K20D focus mode switch, opinions sought.

The focus drive is driven by a pin - when you switch to Manual, the pin is pulled back into the body. When you switch to Auto, the pin is pushed out of the body. Occasionally, the pin won't lock immediately, but will click back in when the focus is engaged. (The lens side is spring loaded) It'...

K20D focus mode switch, opinions sought.

Thanks for the replies. I should have added that it happens with the lens on or off the body, currently I only have the one lens :wink:. Yes it seems to be the drive screw / pin mechanism clicking as the lever is turned from manual (retracted) to C and S auto focus (out). Oh I should also add tha...

K20D focus mode switch, opinions sought.

Mine also makes that noise - but it doesn't sound wrong so I'm not too worried about it. I noticed it yesterday when trying out a manual lens. I'd be surprised if that mechanism was prone to failure but, equally, if your last copy didn't do it then who knows? My camera also makes a small noise wh...

K20D focus mode switch, opinions sought.

The noise from the AF switch is just the screw drive popping out. It's normal. It's not always audible, and probably your original camera would have made the noise too sometimes, Greytop, but you just didn't notice it. Just remember that the switch does something mechanical as well as electrical, an...

K20D focus mode switch, opinions sought.

The noise from moving the camera from horizontal to vertical is normal with all models with Shake Reduction. I think it's the floating sensor moving. :roll:Floating sensor noise nothing to worry about.8)

K20D focus mode switch, opinions sought.

The noise from the AF switch is just the screw drive popping out. It's normal. So your K20D makes this noise too. I must admit I'm not 100% convinced it's right. My original trade (many years ago) was an instrument maker so small precision mechanical/electrical assemblies are not something complet...

K20D focus mode switch, opinions sought.

Sometimes mine makes a noise, sometimes not, and it doesn't always sound the same when it does. There may be some imperfection in the assembly, but I can't imagine it causing a problem as long as the screw engages with the lens.

K10 Focussing Issues

Cam someone explain why this camera will no longer focus properly. I have wasted a lot of time and been VERY disappointed at the accuracy of focussing-and this seems to occur with ANY lens, even the 16-50DA.Images often appear soft/blurred. This is NOT a problem with my technique or camera shake. Ev...

K10 Focussing Issues

Hi there, welcome to the forum. Sorry to hear about your focussing problem. When you say you get inaccurate results when manually focussing, have you tried using a tripod to do manual verses auto focus? I have done this in the past and used a target like news print taped to a wall. Also use a time...

K10 Focussing Issues

If the problem only occurred immediately after the service, I would suspect that the service engineer has made an AF adjustment via the Debug menu. This could be put right. This would also affect manual focusing, because there would be a discrepency between what you see through the viewfinder and...

K10 Focussing Issues

Did the camera focus fine before the service? If so then why are you not sending it back to have the focussing issue looked at ? What was the service for anyway ?

K10 Focussing Issues

I'd be interested to know who serviced it since I had a camera 'serviced' and then couldn't even mount a lens let alone focus! I know this is cold comfort but it isn't really difficult to clean the sensor yourself, this forum is full of sage advice on the subject. Could you show us some examples?

Help please, all picture files taken today disappeared from K20D

Hi Amin, if you've seen the images on the card, then they'll still almost certainly be there. What can happen, is that the file directory can become corrupted, and as Windows uses that as it's references to identify files, then that will explain why they seem to have dissapeared. File recov...

Help please, all picture files taken today disappeared from K20D

Thanks for all your help. I downloaded one of the recovery softwares and managed to retrieve the files :lol:. I am really really thankful for all your help. Liam when I put the card back in the camera I couldn't see today's photos. Only the ones I had left of a few days ago. The whole folder h...

How much to replace a K10D LCD screen?

As to how it happened? Apparently, as good as the Lowepro Slingshot 200 is, either I had way too much packed in it, or the padding doesn't do as much as I'd like. Don't get me wrong, I'm not really blaming the bag, but hey, I didn't do it... The bag, packed and zipped, fell a couple feet from...

DOF

I'm getting more and more puzzled about DOF. I have just bought a 70 LTD and very nice it is too, no complaints there but I took a rather dull shot of which a 100% crop is as below. What I don't get is 70 mm lens at F2.8 The focus was on the bricks The sign is out of focus and it's a ...

DOF

it's really on the edge of the DOF so it might be a little back focused maybe since the wood on the back is still fairly sharp.
