Dear all,
My dad uses the above combo for bird photography and wants to improve the quality of the pictures he takes. He is of the opinion that the 400mm DO lens + 1.4TC gives rather low contrast shots even when stopped down to F7.1 or F8 or so. There is also some loss of detail compared to my sister's 300mm F4 and my 400mm F5.6. He shoots mainly using Av mode and sometimes overexposes the picture by +0.33 EV. The IS on the lens is often turned off when tripod-mounted.
Is there any way to improve the quality of pictures obtainable through this setup? From reviews on the net, I gather that the 400mm DO lens is a rather touchy one to work with, that is it can be absolutely superb or downright lousy. Can the IS be used on a tripod like Canon's other L-grade telephotos?
Appreciate your comments greatly. :t:
