Sure! My candidate is the 400DO. Wonderfully light when compared with the 400 F2.8, a lens that I can hike with. And, just great for bird and wildlife photography. It's as sharp as any telephoto I own. Apparently, this lens got bad reviews back when it was introduced and has languished in the shadows for years. It has a bad rap, take my word for it. Mine is my favorite lens.
