I have a Nikon P4. I am using a Sandisk Ultra II 1 GB card with no problem. I would like to get either a 2GB or 4GB Transend or Ridata 150X card. Would anyone know if the P4 will recognise, format and be able to use a card of that speed. The manual only shows 1GB as the limit, but I find that hard to believe. Steves Digicam review of the P4 mentions him using a 150X 512MB card. I would go with the 2GB but the 4GB would help when recording video. PLEASE ADVISE IF YOU ARE IN THE KNOW. So far this camera is great. I had a Nikon 880, traded it for a SONY, and now back to Nikon (Which blows Sony away)......Thanks
