Summary: Love the lens. It is a perfect compliment to my D800E. I do recomment stopping it down to 2.0 for better color corner to corner (some vignetting at 1.4). Really becomes sharp from f/4.0 to f/16. This is a great landscape and interior focal length. Resolution is a good match for the D800E. I expect this to perform well with future cameras as demands on lens quality continues to be challenged.
Summary: I couldn't of been happier with the seller. A+ from him. On to the actual lens. After unboxing this beauty, my first impression was its extremely heavy for only 24mm. Without looking at specs, I would say its close to my 24-70 2.8. You can tell right away that its built well and will deliver. I am a huge fan of prime lenses and just by taking a quick test shot, this lens is SHARP and the DOF is amazing.
