Hello There,I have taken some shots last nightI piggybacked my 350d on my ED80 refractor.I own 3 zoom lens that I could never attach to it because they were Pentax K mount lenes.I bought a Steve mogg adapter so now I can attach the K mounts to my 350D.The zoom I attached last night was a Sigma 100 to 300 zoom. last night I set it at the 135mm mark opened the apto 4.5. You have to do every lens adjustment manually.Because it a digital camera if you set the lens at 135 you multiply that by 1.6 which gives you a zoom setting of 216.I took about 13 shots all up and moved the zoom above and below that setting.THe ISO speed was 800.-img-2336-181secs/ img2337-238 secs/ img-2339-130 secs/img-2340-158 secs.The best thing about last night it was fairly cool and the humidity wasn't like the night before.reguard's Tony.

Well done Tony! nice and sharp! a good result for a zoom!
I wish I knew about those adaptors before I sold my K-mount lenses.
cheers and happy new year!

Hello There'these are shots of the EOS350D camera with 300mm zoom fitted.The camera alongside it is a Pentax film camera thats the one I got it had the 2 sigms lenes with it in the purchase deal.I have an Astron zoom lens as well with K mount.I think Steve Mogg Only started selling the EOS k mount about 4 or 5 months ago.When I got the Adapter off Steve I purchased the EOS with m-42 screw mount as well.So if you have old lenes with the M-42 srew mount like the earlier Pentax lenes and Pracktica lenes. You can screw then onto your EOS camera.If your an Ebay fan you can buy these on EBAY.I'd Sooner buy them off Steve Mogg myself because you are buying off an Australian company.He has also made a remote Timer for the EOS camera's.Reguard's Tony
