6 is semi-pro
60 is enthusiast
600 loves their cat and pretty flowers.
1100 is basically a bridge, although pure dslr
1dx is pro, there is another level above, medium format, which Canon are not involved in.
So on your logic (which agrees with mine ie the less noughts after the first digit the better the camera in that range)
is
7 semi-pro
70 is enthusiast
700 loves their cat and pretty flowers
is the five range better than the 6?
is the 6 range better than the 7?
why doesn't anyone use the 3 range?
I know 1 is the best - isn't it? (in the number series range)
So many questions.
