Title: Canon 400 DO is Wildlife Solution!
Review: Lens is great!! There is a slight issue with contrast, but this is easily adjustable by adjusting internal camera settings or by computer software. With my canon 7D, I can set the internal contrast adjustment on the high side and compensate for the issue With that adjustment, picture quality is better than my canon 100-400 f4-5.6. Has good sharpness at long distance, which is a primary reason for purchase. Also does very well with a 1.4 canon converter. I like the lens because it is relatively light and more compact than canon,s other prime 400s. This works very well for me since I shoot mostly wildlife and the lens can be easily handheld and I have carried it for 6 hours in rugged terrain using a shoulder strap with no problem. This is a great lens for the serious wildlife/nature photographer. I highly recommend it.
