As some may already know, I technically have a fresh start at rebuilding my DSLR kit. Here's the back story: https://photography-on-the.net …/showthread.php?t=1061272
So... basically, I no longer have any Canon bodies and lenses. My close friends, cousin, and sister all use Canon but I've been contemplating going with Nikon (D700, I want full frame not crop). Reasons?
1) Better flash system.
2) Better AF (D700 vs 5D2)
3) Weather sealing
Along with that, the M9 has become my primary camera even before the accident. Before the switch to the M9, 99% of my shooting including paid work were done with primes. The only time I need an SLR kit, for the time being, is if I need to use flash or if I need to shoot products (close focus). Now my close friend and I are business partners and we share our gear. His kit consists of 5Dc, 7D, 35/2, 50/1.4, 85/1.8, 28-70L, and 70-200/4L non-IS which covers all of our needs. My cousin has a 40D and 50/1.8 and 28-135. Sister has a 20D w/kit lens. I can pretty borrow their gear whenever needed. If I rebuild my DSLR kit, I'm going to go all zooms. Leica and Zeiss primes on the M9 are unbeatable.
Now with that said, should I even consider Nikon since I'm already so "invested" in Canon? The better flash system, AF, and weather sealing would be great and from what I've seen Nikon's 24-70 is sharper than the 24-70L. So what does everyone think? If I stay with Canon what should I get to replace my gear? I mainly shoot people (portrait, model, actor head shots, and weddings) but also do product shots for work (which uses a Nikon D40x with studio flashes).
Additional info, gear I've owned previously or shot extensively with before:
Bodies: 20D, 40D, 7D, 5D, 5D2, 1Ds2
Lenses: 35/2, 50/1.4, 85/1.8, 35L, 50L, 28-135 IS, 17-40L, 24-70L, 70-200/2.8L non-IS
Any input would be great!
