Hi all 1st let me thank everyone here for there help in either there posts or articals I have learnt loads from all of you. I have a question that hopefully somebody can help me with. I recently bought a Sirius 60-300mm lens. It was sold as a working Pentax bayonet fitting, apart from that the seller knew nothing else, but for less than £10 I thought what the hell. When I looked at it further I found it was an old Ricoh KR fitting and wouldnt fit my Pentax K-r without removing the pin that was used on the old lens (Using a tip I got from this site it was removed in a couple of minutes). Now the lens fits and looking through it is as clear as a bell, however it will not let me shoot photos and just comes up with the Av option on the led screen. Please does any body know how I could get this working?
Many Thanks
Ric

Does it have an aperture ring?

If there are no electronic contacts on the mount you will be limited in how it can be used. Av or M only and stop down metering.

If there is an "A" on the aperture ring then set it to "A" and the lens will work normally.

Best regards, John

If the lens has an 'A' setting, then use that; the camera will then meter normally, use the camera to dial in the aperture rather than the aperture ring on the lens.

If it hasn't, have a look in the camera manual for 'E-dial in Program' (should be page 105.)
This shows how to set the camera to use the green button to give a shutter speed or aperture value automatically. If you do not have the camera manual handy you can download a copy from the Pentax web site.
