Me and a few mates are embarking on a sub artic photography trip later in the year and I've almost convinced myself into a 200-400 f4 NIKKOR as my big lens to purchase. The reason is I like the flexibility of the focal length it will provide me. I don't care about the weight or physical size.
Does anyone out there use one on a regular enough basis to provide some constructive feedback? I've read a few reviews but am interested in what you have to say in this forum.
However, I'm open to all feedback on "big lens users" so if you use one can you please provide me with the reasons you chose what you chose, it may open my eyes to something I've completely overlooked or am not even aware of.
