Hello all,
I am using a Canon 300 mm f/4 with canon 40D and seldom use the 1.4 TC with this because I am noticeing that the result of this combo is not sharp and good. Now the reach of 300 mm is something I felt less and I want to upgrade to a larger focal length. I don't know whether the problem is in TC or not. Is this a good decision to upgrade to a Canon 400 mm f/5.6. At present I do not want to spare more money for 500 mm or so. By the way I have a plan to upgrade my camera to 7D also. So please suggest me what should I do.
Regards,
