It's not a repair manual you need, it's a new objective retaining ring.
You will need to find your Pentax agent and have them put in for repair.

I own a Tamron SP 80-210 adaptall II len with Pentax mount. I currently own a Nikon 7000. Can I use the Tamron with the Nikon by adding a adaptor? Any suggested adaptor I should be using? Thanks

Hi, The focal distance on Pentax camera's is different then the focal distance on Nikon's so because of that Pentax lens' can't be adapted to work on a Nikon camera. I'd suggest finding a similar lens with a Nikon mount as cross brand mounting is quite difficult.

I have a pentax slr film camera and i want to know ii the lens will work on a Nikon dlsr digital camera

No. Nikon has been using the same lens mount since about 1959. Pentax has changed their mount once since then, but not to the same thing.

How do I know what size lenses to look for?

Hi rlopez117,

Congratulations on the aquisition of such a great vintage camera!

Pentax cameras use a mount known as M42. This means it is a 42 millimeter diamater. You may also find this referred to as the Pentax mount, as Pentax (Asahi Optical) made this popular in the United States. With any camera, any lens you purchase should match the mount of the camera in order to be used together.

Thank you,
Jason,

Pentax K100d super

I fixed the problem. It was caused by an extra little pimple on the sirius lens slipping into the auto focus indent indent on the camera body.

It is possible to get up to a ten thou engineers feeler gauge into the gap between lens and camera body although the one that did it for me was a three thou gauge.

I needed to cut the feeler gauge square at the tip and then, even though it was only three thou, I hit the tip by resting on a vice and tapping with the ball end of a small ball pein hammer. This caused the tip to form with a small curve. I then used a tool makers file to smooth the end down to almost nothing.

Turn the camera AF MF switch to AF to raise the screw. Fiddle the feeler gauge into the slot between body and lens just near the AF MF button and very gently probe the gauge. You are trying to get the little curve you made on the feeler gauge to slip over the pimple on the lens.

Its a very nice feeling when the gauge slips right in and the lens comes free.

The next proceedure, if you want to use the lens, is to unscrew the aluminium mount at the end and remove the offending pimple on the lens.

My Optio won't stay powered on.

This is probably due to a broken sensor tab inside the lens, or a failed sensor. When the lens reaches the end of its travel a small plastic tab will pass between the ends of a C shaped sensor and let the camera know the lens has reached the end of its travel. You are not hearing a safety device, you are hearing the gears actually slipping. Don't let it do that too much or you will turn one problem into two problems quite quickly. If you cant find the broken part it will require professional repair. I would advise against taking the lens assembly apart. They are extremely hard to get back together and you very well may end up with a junk camera. David Millier Advance Camera Repair
