Canon cameras autofocus

[davholla14]

Is there any website which compares autofocus for different canon cameras?
So we can see if changing from model x to y will show an improvement?

It would be very nice to have a website like that, but I don't know of any.

Comparing AF performance will be very complicated, because it will depend on subject distance, contrast of subject and background, ability to recognize features of the subject, lighting, etc.; and performance can change with a firmware update.

I agree with above that it would be very hard to keep an up to date comparison however with Canon if you look at the sports and wildlife focused cameras or the most expensive two, they will usually have the most up to date and best performing autofocus.
However if you are looking for a comparison between two specific cameras, there are plenty of real world write ups with comparisons. It does take a bit more searching but they are out there.
