Looks like it's f/6.3 @ 270mm. Do you think that this lens can match the IQ of the Canon 70-200mm and 300mm that I have (honest question)? I was under the impression that that wasn't quite the case.
Im sorry. As you read more from me, youll come to understand when Im joking
I wouldnt put the 18-270 on anything I own.
If you care that much about pictures, just use two bodies. Who cares!
