My Aperture shows 00 in my digital display and no auto focus
I had the shutter replaced and have only now for the first time put a lens on the camera ,i find that the auto focus does not work and the aperture does not register in the digital readout.I fetched it yesterday and need to do a shoot today ,its Sunday you the only one that can HELP !
Re: My Aperture shows 00 in my digital display and no...
Aperture 00, that means the body don't identify the lens, or there is no lens. try to see if the lens contacts are in order. Try another lens, par exemple you can go to a shop and try the most beautiful lens you ever seen for free.

When you put your camera to M with the main dial, it should not have any effect on the focusing. With M you only can choose your Aperture, Shutter speed and ISO manual. With P, the camera will choose a setting it thinks is the best, but you are allowed to change it like another speed or Aperture setting. The camera will try to compensate with ISO, when you are out of the normal limits.
Just when you put the AF / MF switch on the body, or on the lens to M. the lens hast to be focused by hand.
A 500 mm mirror lens is a fully manual lens (manual focus no aperture change) using a T mount adapter to your specific camera. The T mount costs some $15. It depends on your camera how to turn off the auto focus and go to aperture priority mode. The aperture on a mirror lens is set, usually at F8, so the shutter is the only item that can be adjusted to get a correct exposure. A digital camera (set in adjustable ASA setting) can change it's ASA to help with getting a correct exposure. Manual for digital camera are usually on the companies' web site.
Set the exposure mode to "M" (Manual). You'll have to set both the aperture and shutter speed yourself.
You'll also get no exposure assistance from the camera's light meter. You can review the picture after taking one and/or use the histogram to tune the exposure.
Make sure the subject is well lit. The autofocus relies on differences in contrast to determine proper focus. Move to a well lit area or add additional light and attempt again.
Make sure the aperture ring on the lens (if that lens has one on it) is set to minimum (highest number - f22 etc.) This value it often a different color ink than the others to help speed locating it. On most Nikon & compatible lenses, when the aperture is set to minimum, the camera's main & sub command (thumb and finger) dials will control the aperture and shutter speed. When the shutter is held down 1/2 way, the aperture will open fully (to allow the most light in and speed composition) and then automatically stop down to the commanded value when fully depressed for the exposure. If you have the aperture set on the lens to something different - it may be preventing sufficent light from entering and interfere with the autofocus function.
Solution 1 • Unlock focus area selector. • Auto-area AF selected for Custom Setting 2 (AFarea mode): choose another mode. • Press shutter-release button halfway to turn monitor o?¬? or activate exposure meter • Memory card is full, locked, or not inserted. • Flash is charging. • Camera is not in focus. • CPU lens with aperture ring attached without locking aperture at highest f/-number. • Non-CPU lens is attached: rotate camera mode dial to M. • Mode dial rotated to S after shutter speed of bulb selected in mode M: choose new shutter speed • P, S, A, and M modes: lower ?¬? ash. • Digital Vari-Program modes: turn ?¬? ash o?¬? Turn long exposure noise reduction o?¬? Turn long exposure noise reduction o?¬? Press multi selector up or down or rotate sub-command dial to choose photo information displayed Select All for Playback folder. Note that Current will automatically be selected when next photo is taken • Select On for Rotate tall. • Photo was taken with O?¬? selected for Auto image rotation. • Camera orientation was changed while shutter-release button was pressed in continuous shooting mode. • Camera was pointed up or down when photo was taken Use Nikon-approved card. • Card may be damaged. Contact retailer or Nikonauthorized service representative. • Delete unwanted ?¬ les or insert new memory car

There is no communications between the camera and lens. When using a set up like this everything becomes manual and you must remember to stop down the aperture to your taking aperture before releasing the shutter. I don't know what camera or format you are going to use this lens with but assuming it is a digital "bridge" (a camera that is between an amateur and a pro) or a professional the sequence would be the same. To view, focus and compose the lens would be set in this case F2, to select the correct light meter reading the lens is set (stopped) down to the taking aperture. The modes I've used for this have been mostly manual but lately I found that "AV" worked equally well and the camera metered to the proper exposure. Most times the camera was mounted on a tripod and the shutter was released with a electronic shutter release. Sequence for taking a photo for me anyway was/is (with the camera mounted on a tripod) focus, compose, stop down to taking aperture, check metering and release the shutter if in AV mode or manual mode to set the shutter speed and release the shutter. You will find that all makes of digital cameras will function differently so what sequence works for one won't work on others. This meaning I have had digital cameras that wouldn't meter through anything other then the lenses meant specifically for them. Problems that I've had. Forgetting to stop down to taking aperture (like Duh), not fine focusing (manual), not trusting the in focus indicator, forgetting that the viewfinder is/was only 94% of the scene. Once a little time has been spent with a lens set up like this the rewards are far beyond the trivial annoyances. Have fun with it
Program: Puts the camera in charge of aperture and shutter speed, though all remaining camera settings are available. You can vary the combination of aperture and shutter speed the camera has selected by rotating the Command Dial. from:http://www.imaging-resource.com/PRODS/D40X/D40XMENUS.HTM The camera takes care of the shutter and aperture settings, and you control the other stuff...(presumably white balance, focus points...etc.?). I hav ea D70 and using the thumb wheel, I can, on 'P' mode, set the aperture...but the shutter speed is always 'auto' as far as I can tell. Best of luck! Nick Chapmanhttp://ChapmanIT.com
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!
Have you tried this same lens with other cameras? Do you have another camera body you can try? or perhaps a friend with a Canon EOS Camera?
Also try the following please:
Remove the lens. Look at the lens mount contacts, take a Cotton swap with some rubbing Alchol & clean the contacts very well, both on the lens and the camera body.
Is your camera reading the lens aperture range correctly (at least most of the time)?
Also since you replaced the PCB on the lens, isn't it under warranty?
Let me know if this works. Thank you, AJ.
