Well fingers crossed then that it is the Canon mount then! They certainly are a lot different, thanks for posting those images Smooth.
Believe it or not, it was the cheapest I could find, other than a company called Sighterz in HK, but they messed me around so much saying they had sent it and it never turned up, I got a refund and found this one. The Australian dollar is very strong right now and it worked out at $926.00 and that includes free shipping too! I checked a shed load of places and this was the cheapest one I could find. There were some slightly cheaper than the one I have chosen, but by the time they added the shipping cost it wasn't worth it. - I hope! I went back to DigitalRev as that is where I got my EOS 450D from cheaper than I could find elsewhere.
Will let you know. Really eager to get going with his and get into the world of virtual tours!!
