I need a Gitzo series 5 tripod to support 4x5 and 8x10 cameras. To now I have been using my trusted 2531EX,which is a beautiful combo with a lightweight field camera such as a Wista 45dx. Alas it must find a new home.
PM me if you have a carbon fibre series 5 that you would be willing to trade. Price difference can be negotiated.
