canon 70d v Nikon D600

i have the 70d but am struggling with the light at some kickboxing venues. medium to very poor lighting. using a sigma 17-50 2.8.bumping iso but as soon as i reach 800 starting to get noisy. someone has said with the nikon the iso can be bumped higher with virtually no sign of noise. i like the canon but, would consider the nikon if right. if not the d600 then which one. price would be up to £1000 second hand?

many thanks

can mods pleade delete. wrong section

You've got to have something set wrong in the camera. I've taken night shots at 6400 ISO with minimal noise. Do you have the high ISO noise reduction turned on in the camera?
here's an example

10-22mm ƒ/4.0 17.0 mm 1/100 ISO6400

Heya,

Expose properly when shooting high ISO and it's not an issue. Also, it will clean up nicely. The 70D has great ISO performance for it's sensor size.

APS-C, ISO 3200 (EOS-M, a sensor below the 70D):

hi i have the high iso nr switched on. i will have to go through all my settings and list them to see where i'm going wrong. i know im doing something wrong but cant figure it out. normal settings i use with a sigma 17-50 2.8
1/500
iso 800
nr on
kickboxing so fast paced low light as amateur venues and a very amateur camera operator
going to have a play about with ettrhanks

Heya,

No worries. It's all about getting used to your camera, exposing with high ISO in mind, the extent that you can push a sensor, and of course, good post-processing (modern, keep up with this, big strides get made often).

Examples (more binned snap-shots, but they illustrate an example in ISO from a small sensor):

APS-C @ ISO 12,800:
