I just got a Ricoh KR-10, and I the focus ring won't move (aperture works fine). It's almost as though it's locked or something. I don't want todamage it, so I've been gentle with it, but I'd really like to get itworking so I can take some photos! Any suggestions?

Re: Ricoh KR-10 locked focus ring
you can fix this if you have a jeweler's screwdriver ( x- head ).
1-take the lens off the camera.
2-take off the front name plate with a thin knife blade just right of H of RICOH name. gently pry the name plate up till it pops off ( not screwed on ).
3-remove the three screws from the plastic ring, ( large ring ).
4- pull the ring off.
5- where the metal ring touches the plastic lens barrel apply a few drops of light machine oil.
try to move the focus ring back and forth until it's free.
it can be further broken down but then the lens will have to be re-focused. as long as there is no impact damage this will work.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Turn the aperture ring to its smallest setting (largest f/number). You control the aperture from the camera body, as on a lens without an aperture ring. Turn the mode dial to M (manual). The camera's exposure meter will not work with this lens. You can use another lens to get an approximate exposure, or take pictures and review them and/or use the histogram to fine-tune the exposure. The camera won't autofocus, of course, but the in-focus indicator in the viewfinder will still light up to indicate proper focus.
You must lock the aperture ring to f/22, so the camera can engage the aperture adjustment lever on the lens. Then, you can change the aperture with the command wheel.
When you change the aperture with the command wheel the aperture ring on
the lens doesn't move when the camera actually adjusts the lens
Take the lens off and locate the aperture adjustment lever on the lens mount.
Unfortunately, this won't work with older AF lenses. So if you are using an older lens, the only thing you can do is change the camera setting to M (Manual) to adjust the aperture on the lens yourself.
You should turn the aperture ring on the lens toits smallest setting (largest f/number). If the ring has a lock, lock it inplace. You control the aperture from the camera body, just as you would on alens with no aperture ring.
The D60 camera sets and triggers the aperture that you have selected (or the camera has selected if in auto mode) and sets the aperture as you take the picture. Moving the aperture ring on the lens will not work, in fact once you move it from the f22 position the camera will stop or possible show and error. on my older Nikon AF lenses there is a small lock to lock the aperture ring in the lowest position when mounted on a digital camera, it is found near the f2.8 side of the aperture ring. when you want to set the apertures manually, you put the camera in aperture or manual mode and set the aperture you want by moving the the rotating wheel on the grip part of the camera. the aperture you select will show in the window, you do not have to move the ring on the lens,it must remain the f22(highest numerical) position.
Check if your battery is charged. Are there any error messages? Otherwise, if your lens has an aperture ring, do note that most of these lenses require the ring to be locked at a certain position for it to work. In the course of using the lens, you may have accidentally unlocked the aperture ring and moved it out of position. This is a common problem.
To fix this error, try this:
1. Turn off camera
2. Turn the aperture ring clockwise and then lock it
3. Turn on the camera
If you still encounter the same problem, repeat the same steps but turn the aperture ring counter-clockwise. Hope this helps.
The aperture ring must be locked in position when using automatic aperture control. When the aperture ring is in any other position the 'format error' message appears and the camera is inoperative. Now that my ring is locked in position the camera works fine.
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.
