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
