Thank you so much Richard. Actually I have just recieved my Cambo Wrs with the 24 & 35xl Schnieder lenses. I did a fair bit of study on the artec and even came quite close to getting one only to realise that it couldn't take the P1 backs as they were meant for rolei/Hy6, I believe the newer artecs can take al backs but they are way beyond my budget. I shall for now depend on the iPhone viewfinder and live view until cambo comes up with a sliding back. Till now I shot on the canon 5Dm2 with the excellent TSE lenses and I was fairly happy, I know for sure the move to MF is going to slow me down a fair bit but I hope to get back to enjoying the 'process' like I did while shooting on LF and though lesser number of shots i hope to get better quality images.
