SLR not working

I had put a Sears 100-300 zoom (older model for my K1000) on my K100D and it sorta stuck when I took it off (I queried Sears about it being used and they said it would work just fine but no auto focus-dah).

It seems to take pictures fine but the view through the eye piece is dim. I can't tell if it is in focus because of it being so dim.

Any answers?

Thanks in advance.

Re: SLR not working

Hi, this may help

If you could send me - or post those pictures you have of the mechanism that would be great.

I also have the link for the service manual for the samsung version of the k10 - it shows how to open it up. Let me know if you want that?

Re: SLR not working

The lens you are talking about has either:
1)a faulty diaphragm mechanism ( lens stays closed at f 22 or f 16 when you attach it to the camera instead of opening fully as it should ) . or
2) the lens is fine but the diaphragm coupling mechanism inside mirror box ( on the left hand side if viewed from the front ) is not engaging the lens properly so that your lens stays fully closed ( F 22 /16 ) : because diaphragm stays fully closed image in viewfinder appears v. dark.
Solution ? have a camera technician take a look but my guess is that the diaphragm needs cleaning and it should not cost you more than $ 80 bucks.

New Pentax K100D Super, shutter does not work. Av -- flashing 688 under battery sign. Replaced new batteries did not resolve problem

I suspect dirty contacts on either lens or body. Clean contacts. Should alleviate problem. This happened to my K100d.

I don't own a K10D, but I do own a K100D which I have successfully used both manual focus & auto-focus lenses from my old Pentax stash!

1) If it is a manual focus lens, you need to turn off Autofocus on the body of your K10D. On my K100D, there is a switch on the side of the lens mount that says [-MF or -AF]. "-MF" is manual focus mode & "-AF" is autofocus mode. Since your lens doesn't have autofocus capability, turn it to the "-MF" mode.

Also . . . When I press "Menu" and go to "Custom Setting", I change two settings . . .

1) I change "Using aperture ring" to "Permitted". This allows you to use manual lenses (M lenses) that do not have an auto(exposure) setting, and also lets you use Auto lenses (A, KA, KA2, FA, etc.) in either the Auto or manual aperture setting modes.

2) I change "Fl with S lens used" so that even with a manual focus lens, although I don't have autofocus capability, my K100D beeps and shows a little red square in the viewfinder when I have successfully focused manually!

The K10D should have the same options.

This should get you up and running!

I have had a load of fun with my old lens on my new digital Pentax!

Take care & Happy Imaging!

K100D flash doesn´t work

My camera with the dodgy flash is holidaying in Japan as they sent it to be fixed - not sure how old your camera is but I am trying to see if this is an issue that occurs with the camera model.... given that there are only two of us to date I am thinking that we may have just struck the jackpot :(

Blurry pictures with Pentax K1000


It may be the equipment or it may be the way you are holding / taking the picture.

Here are suggestions on how to take better zoom lens pictures (this also applies to any camera) before you start diving into the equipment.

1) Use the fastest shutter speed possible. This reduces the amount of time of exposure, this limiting the amount of motion blur that can happen.
2) Don't hold the camera by hand. Either use a tri-pod or rest the camera on something stable, like a wall, rock, bench, etc. This makes it less likely that the camera will move when you are taking the picture, thus reducing motion blurr in the image.
3) If you have to hold the camera by hand, hold the zoom lens with your left hand (because it is more towards the center of gravity than the camera is) & try to slow your breathing & take the picture between heart beats.
4) Also, another thing that helps is to use a remote shutter release (such as that rubber bulb or plunger attached to the shutter release). I would also say using the self-timer would help, but the K1000 doesn't have that. This is so the camera doesn't shake from you pushing the shutter release button.
5) Make sure the lens is clean! Even get one of those lens pens from your local camera shop.

If you have tried all (or most of these) then its time to start looking at your equipment, such as . . . is your shutter getting stuck when exposing, thus lengthening the exposure and making for a blurring shot or do you need glasses? <grin -- which is why I find it really difficult to use manual focus equipement now, because my eye sight is really bad!>

Take care & Happy Imaging!
