I dont think its a nikon vs canon thread at all.... i think its more a high iso when resized for web thread.... a canon v nikon one would point out scientific comparisons that really dont matter.
regardless of the camera used the shots look great! These are the sorts of situations that sometimes need high ISO and high shutter speed... perfect for the new breed of canons and nikons!
Looking at high ISO shots is about getting as much out of an image as possible usually after you have taken it - trying to do the best of a bad situation... and then seeing the results. Also knowing what you can get away with - at a push
Canon vs Nikon means your actually willing to dump usually at least 10k worth of equipment for what? a supposed 1 stop difference - in a zone that most dont even shoot in - i get it if you are an indoor sports shooter or something similar - but they are so specialised they can probably afford to swap to stay at the top of their game... otherwise its a debate not worth getting into!
if your processing iso 6400 shots daily then there isnt even any point arguing - that is the point where you shoot both and choose.
god knows how it was done in the days of film.
Thank you Nicko, finally someone that actually understand that this wasn't meant to be a C vs. N thread. I just shared an example of what i believe was brilliant images of good high ISO performance.
Others have posted other examples which also looks great (at least ISO wise) , good to know that "OUR" brand is equals the competition ISO wise. Though i bet that if these images were posted as Canon images in here the response would have been rather different.
I'm very happy with my Canons and will probably stick another 25 years with them.
