What to do? What to do? Recently sold my 5d2 and waiting on next announcement from Nikon or Canon. Have a D800 set to arrive in the next week. Beautiful DSLR. going with the Nikon 16-35vR or Tokina 16-28 if I keep that camera.
I needed high MP like poster who uploaded Castle or whatever that amazing building was. Still, I am almost intent on sending back the D800 once it arrives. Too late to cancel right now. Anyway, only the higher useable ISO of the 5d3 are of interest to me over the D800. Well, and build quality supposedly on par with Nikon's offering.
I would hope the low iso files of the 5d3 are noticeably cleaner than 5d2. The JPEG engine on Canons are generally superior to Nikon (I should know -- I've owned the Nikon D70, D80, D700, and D7k, Canon 40d Rebel XS, and 5d2). Canons also meter better. Yes, with its more simplistic metering my Canons produce scary good exposure results. And finally, Canons are generally more user friendly. The final statement I want to make is this: why did Canon only allow 5d3 users to choose between highlight tone priority OR shadow optimizer? Weird choice to force you to choose one or the other.....to me it is, at least.
