Depends whether we are talking about resolution on the sky. With a 300mm lens and 16 odd micron Bayer matrix, then the system will resolve around 11 arc sec per pixel. eg you could not split say a 4 arc second double.

Going to 3000mm you will have 1.1 arc seconds of sky on the same Bayer group. Our double star from before is within easy reach.
