Can anyone tell me why there is such a difference in price? What are the different features?
The Nikon SB 900 is a high end dedicated flash designed specifically for Nikon Dslr‘s with special patented features NO generic flash can have.
The generic YN465 has a guide number of 33 (ISO unknown), the SB 900, guide number of 157 at 200 ISO
There is no mystery here. One is a dedicated flash designed by Nikon of their Nikon cameras The other is a generic designed to be used at a lower level of efficiency than the Nikon flash
