Actually I have a Tamron 150-600. I was thinking that it was very soft, but I have since found out that my bird photography techniques need improvement. Getting the speed up to 1/1000 and above. I guess I will do more practice before I change out lens.
My original thoughts were from online material that said a L 400mm prime will be sharper cropped than a 150-600zoom.
Sure, I understand. Was just curious. I also have the 150-600 Tamron and am just getting going with it. My initial impressions are pretty solid. I would say that I've not done anything specific at the 400mm mark to judge sharpness. Good luck. I see you are from Minnesota, I'm from North Dakota, soon the weather will change and we'll be able to be out learning our new lens. novots.
