I don't have the budget to upgrade and besides, I love my P45+ back. I'd love to have live view though and I'm wondering if I could mount a little Sony RX100, either in the cold shoe of my camera, or attached to a magic arm in front of the lens and then swinging it away for capture. In the case of the cold shoe I'd have to measure the distance from lens center to lens center and then compensate for capture by raising the tripod center post by that amount. Sounds doable. Is there a catch - or better way? Thanks.
