I rented the Sony 200 – 600 mm zoom for an upcoming bald eagle photographic trip. I put it next to some of my other lenses for a size comparison. Darn thing weighs almost 5 pounds so it’ll have to be a monopod for me because the trip will be pretty long. Look how small the FE 35mm f\2.8 looks. I’m interested in this lens but I’m hoping it’s sharp enough to warrant the $2,000 price tag.
