So the day has come. I have decided i am going to make the switch. I plan on getting a d700 with grip and a d300 with grip d700 to be used for everything other than nightclub work. d300 will be for club use only and as a backup. I want to just pretty much swap everything over. 16-35 ---> 17-35 2.8 28-70L ---> 24-70 G 70-200 ---> 70-200 VR Sigma 50 -- Sigma 50 Sigma 15 fish ----> sig 15 fish my question to you guys is that do you find that the d300 is a sufficient back up to your d700? Otherwise i will just get two d700s. and maybe a d70s for clubs and also for the flash sync.
