I was recently testing the high speed burst mode on my 60d and noticed that it reduces in speed when shooting in low light condition and I don't know why. I had the camera in manual with a fast shutter speed, low iso with noise reduction turned off, Jpeg only with manual focus. I have read the manual and it does say it will do this but I don't understand why. Can anyone shed some light on this?
 
At High ISO's most cameras still perform a certain level of noise reduction even if totally switched off in the menus. My guess would be its this NR processing that's causing the slow down.

It's so that Canon can annoy their customers some more. What's most annoying is that the 7D does the same thing. Here's a post on PotN that explains it with a short extract
the fact that the iFCL metering system always determines focus with all focus points (detecting focus takes longer time in low light)

But I've set it to manual focus so this shouldn't really apply.

If you read that PotN link you'll see that it doesn't matter. The camera uses AF information as part of its metering algorithm, regardless of the focus mode. And even if you use manual exposure, the camera still needs to run its metering process for the exposure meter in the viewfinder.

Many thanks. I did read the link but it didn't make much sense. Your explanation seems much clearer
