Question about Pentax K100D Digital Camera

1 Answer

Camera locked Hi, I've got the blinking battery symbol when I switch on my K100D. I've tried switching to manual focus and leaving for a while with the batteries out, but still the same issue. It works ok with external power supply, so I uploaded ver 1.02 firmware to see if that would solve the issue but still the same fault. Is there anything else you can suggest I try? Thanks, Brian

Put in new batteries. If you're using rechargeable batteries, they already have a lower voltage than regular batteries. If you don't have enough milliamps in the battery, it will show as low, no matter what the voltage is.

Fixing a seized AF motor


One theory on this is that the camera's software or settings may somehow be corrupted, so you should go through the process of resetting the camera to its original factory settings. If that does not clear up the problem, try another AF lens and conform whether the problem is the lens or the camera body. If the camera is not focusing another lens, then you may need to clean the contacts or look for some sort of damage.

If it turns out that it is the lens, the best solution is to send it to Tamron for service and see what they can do about it.

If you cannot send it to Tamron, you ought to see whether it is something as simple as some sort of internal dust or dirt collection blocking the mechanical switches and functions of the lens.

Start with making sure that you have a fully charged battery for the camera or AC power adapter for the camera. You do not want any of the problems with the camera to be related to having too little voltage available.

Make sure that the camera's power switch is switched off. You do not need to have the battery or adapter connected just yet.

Next, with the lens off of the camera, switch back and forth several times, firmly, between AF and MF and switch the vibration compensation off and on a few times. Of course, do not drop the lens. Also, unless you need the zoom ring locked, you may want to make sure that the zoom ring lock is fully off. While you are doing this, or after switching back and forth, check the electrical contacts on the lens and the camera body. If anything looks even a little less than shiny, clean the contacts.

With the camera's power still switched off, put the lens back on the camera.

Either put the battery in the camera or connect the AC adapter.

Set the lens to AF with vibration compensation off.

Switch the camera's power on.

Try getting the camera to automatically focus on something. If it works, turn the camera's power off, then switch vibration compensation on, then turn the camera's power on and try again. It may be fixed, at this point, which means that you can ignore the rest. Otherwise:

Turn the camera's power off again and switch to manual focus. Turn the camera's power back on and rotate the lens's focus ring (gently) all of the way through the focal range two or three times. Try taking one or two pictures, just to be sure that everything is working in manual. Turn the camera's power off and switch the vibration compensation, then turn the camera's power back on. Gently rotate the focus ring all of the way through the focal range two or three time, and then take two or three pictures to verify that everything is still working in manual.

After that, turn the camera's power off and switch back to AF with vibration compensation off. Turn the camera's power back on. Try to get the camera to automatically focus on something. If it works, then turn the camera's power off and switch vibration compensation back on again. The turn the camera's power on and try to get it to automatically focus on something.

If all of this works, than you should be okay with it as it is. You may still want to send the lens in to Tamron to get it serviced, in case the problem was some sort of lint or dirt getting caught up in the gears or servo that moves the lens through the focal range.

If it does not work, you could try to force the lens to re-engage the autofocus servo. It will probably void your warranty, if you still have one, so you are better off send it in to Tamron for service, first, before trying it. Also, as the manual and common sense would indicate, if you try to force the lens to adjust its focus ring while it is switched to AF, you could easily break the mechanism in the lens.

With that being said, some people claim that they got their lenses to return to proper autofocus by leaving the lens switched to AF and trying to rotate the focus ring manually. One person says not to "force" it, his just took a "firm push". I have not tried this, so I do not have advice on how much force may work or how much will damage the plastic bearings, gears and teeth inside the lens.

I have just started using my husband Pentax K100D camera. The viewfinder seems really dark. My camers is a Fujifilm S5700 that seems to have a lighted viewfinder. Is there any way to make the viewfinder...


The best way to lighten the viewfinder is to purchase a new focusing screen. There are many alternatives available and usually cost around $100. There are specialty screens to allow better manual focusing and others that brighten the viewfinder. These effects are usually achieved through coatings on the screen. They are relatively simple to install, however if you are uncomfortable doing it yourself, a local camera shop should be able to do it in a matter of minutes.
This screen will allow better focusing of manual lenses and will also brighten the viewfinder, when you purchase the "Brightness enhancement treatment" option at the bottom of the page. http://www.katzeyeoptics.com/item--Pentax-K100D-K110D-K200D-K-r-K-x-Focusing-Screen--prod_K100D.html
The linked product also fits your camera, and the brand is highly regarded as being good quality. There are other options available though, simply search on B&H Photo Video or Adorama Camera. They have many different options.

Pentax K100D will not power up


First make sure you are using fresh lithium batteries. These cameras indicate low batteries quite early on. Rechargeables even when freshly charged are marginal.

If the problem persists remove the batteries. Set the camera switch to the off position. Set the focus switch to manual. Wait at least a minute. Then replace the batteries and switch on again.

Operating with low batteries can confuse the firmware and it may be stuck in a low-battery loop. If this is the case this should reset the camera by allowing the electronics to power-down completely.

If this does not work you wiil have to contact pentax support.

I BOUGHT A PENTAX K10D THAT CAME WITH A VERY NICE AUTO ZOOM LENS. I OWN SEVERAL OLDER PENTAX LENSES THAT I USED ON MY K1000 CAMERA AND I WANT TO USE THEM ON THE K10D. I CANNOT FIGURE OUT THE SETTINGS THAT...


Hello,

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!

If this is a manual focus lens, you will need to do two things (and an optional third thing.)

1) On the side of the camera, you have to switch the focus mode switch from "AF" (Autofocus) to "MF" (Manual focus) . . . Yeah. I know, you probably already did that. <grin>

2) When you press Menu, go to the Custom Setting and change the Allow aperture setting to on, so that the Pentax K100D will then work with manual control of the aperture ring. You need to do this or the K100D will not work with manual exposure lenses (M lenses) or even autoexposure lenses (KA, KA2, FA, etc.) when you move the aperture ring from the "A" position to one of the manual aperture settings!

3) This is optional, but in the Custom Setting you can also turn on the Fl in manual focus mode, so that even though you don't have autofocus capability, you will get a beep indicator when you have successfully managed to manually focus your lens.

I have a few nice manual focus lenses that I have a lot of fun playing with on my K100D.

Take care & Happing Imaging!
