Hi everyone,
I have just bought a canon 300mm f2.8 IS for using with 7D. I used 400mm 5.6 with 7D before 300mm f2.8... But I have soft images that I expected from this new combination. Should I make calibration or custom settings for 7D with 300 2.8 to improve image sharpness and quality ? I will be apreciate if you help me...
Thanks...
