I've got the original loupe (I'm guessing 5X) and it works fine. Really can see sensor and in perfect focus to examine it.
The Artic Butterfly brushes....... I got them with a cleaning kit. Never used them, I'd sell them here if I could find them. The spinner and battery and static discharging and all that other stuff (to me at least) is CRAP............ I figure if I can't blow it off, might as well wet clean it......
Next I also use and swear by the GREEN Visible Dust swabs and SMEAR AWAY SOLUTION. Other solutions I've tried have "waterspotted" on occasion, SMEAR AWAY doesn't. The green Swabs are different than the orange ones (different material) and TO ME they seem to work better (I have a bunch of orange ones I'd sell). Everyone one here say use CopperHill (which may well be a fine product but I'm not testing it on my camera), BUT TO ME, I don't want to wrap a Tissue (and get god knows what on it) around a spatula and swab my sensor with it..........
I've cleaned sensors MANY MANY MANY TIMES and no problems, no sense messing with success......
On the 5D I can say this (had 2 at one time). As time passes and you clean it many times (about 20 or so for me) INCLUDING the inside of the area around the sensor, you seem to get the dust out that came from the factory and it seems like overnight there are no dust problems. Mine was nasty looking all the time, MANY MANY cleanings later, suddenly it was clean all the time, no further problems......
