Pentax K-mount lenses. http://en.wikipedia.org/wiki/Pentax_K_mount#List_of_Lenses_with_any_K-Mount_Variant
Yes
Pentax screwmount lenses (M42) will fit differently branded cameras with the same mount. It will easily fit other camera mounts including digital bodies using a cheap adapter. Just make sure you use the correct version of the adapter that focuses correctly to infinity. With Pentax K-mount lenses, there are existing adapters that will mount these to a four/thirds system camera, the Canon EF EOS, the Minolta MA or Sony Alpha and the Leica M39 screw mount. Take note that in most digital bodies, the lens can only be used at manual mode. Some camera models will not meter through it even at stop down. Pentax dSLR bodies will meter through them and add Shake Reduction and focus confirmation even if the lens is full manual.
No, unless you make an adapter for it. Surprisingly, the Nikon bayonet lens will fit the Pentax K body. Only loosely. Infinity is incorrect but if you handle it carefully, you can take a picture with it.
Chinon lenses are either M42, 'Pentax screw.' which can fit any digital body with the relevant adapter, or Pentax K bayonet which will fit Pentax or (most) Samsung SLRs. NB they will only meter stopped down to the taking aperture, and offer neither autofocus nor shutter priority/programmed modes. There is also the fact that film SLR lenses need longer focal lengths than their digital cousins due to the sensor being smaller, thus a 50mm standard lens for film is a short telephoto for digital.
The 2x Digital Telephoto Professional Series Lens fits kodak easyshare.
Most lenses and mounts are proprietary so no Canon lens would fit a Pentax without some kind of adaptor.
It depends on you new camera, you should ask about adapters from Mamiya to your new camera
yes
Yes, no problem.
The Canon AE1 lens will not fit a Canon digital. You can buy an adapter that will allow the lens to work in manual focus mode on the digital camera.
Yes as long as it's not pre AI
