I am on Canon.. my brother is on Nikon.. so i use both brands ..
what I can say is :
Nikon:
-so far i see the ISO3200 on a d90 vs 500D .. nikon wins. I havent compare a D300s with a 7D yet.. anyone can tell?
-nikon lens maybe more expensive but generally (the lower range ones), the nikons are better build.
-and since its more expensive on nikon , their DX lens hv silent wave motors.. similar to USM ... which is good
-nikon lens line up is less then canon but it covers almost everything... anything lacking can be found on Sigma/Tamron...
-i find that nikon build is better for their 50mm f1.8, 18-200mm, 18-55mm ... i think
assume the other lower end lens ie less then $1000) is gonna be better build then canon too
Canon:
-L lens are mostly superb ... but how many u gonna get since price is pretty much on premium too?
-cheaper price for lens in the lower end ones.. but compromise on build quality
-better HD video on canon , example 500D vs D90 , and 7D vs D300s
-Canon service in vivo... great place to wait, lousy place to go (vivo pretty far to many ppl) ... nikon in Tj Pagar .. easier.
anyway this is just something i personally feel only la... but i dont really see why need to switch as both brands are good.. if u already got more then 2-3 lens i think just stick with it.. unless u got some problem with the brand itself so a swtich is unaviodable
for me, i hv a urge to change to nikon becos i just loveeeee shots without flash... after reviewing the cleaniness of the D90 ISO3200, i think i might want to switch over.. then couple it with a 35mm f2 lens ... i am sure i will love the result
