Hi TRR - The F5 will play fine with all your lenses. The only thing that I miss when moving from F5 to F6 is the input dials on the vertical grip - the F6 has them, the F5 doesn't. The custom functions are much easier to set on the F6 than the F5, but once set I don't really change them so this isn't a big factor. Oh - and that annoying locking button on the F5's on / off switch! I also love using the Nikon EN-EL4a batteries in the F6 - saves carrying around all those extra AA's for the F5. However these are pretty minor points. In it's favour the F5 has a proper mirror lock up rather than one as an option on the shooting speed dial.
