Question: Does this come with a lens hood?
Document: Comes a lens hood and case.
This is one of the sharpest lenses I've ever used! Beats out almost all my Nikon lenses wide open, some of which cost 5x more! AF speed is just OK, since it doesn't support the phase detection autofocus of the NEX-6 and 5R, but definitely not sluggish. Manual focus ring is buttery smooth and very responsive. Lens hood reverses for extra compactness.
I have the new silver version, and does it ever look nice on my silver Olympus  E-PM2. The sweet spot is at f5.6 where it is sharp across the whole frame. It balances quite nicely on this camera, and a lens hood is included. Sigma has done an awesome job with the glass. If you don't have such deep pockets but you want to try a fixed aperture lens, this is the one!.
I had this lens for a year and a half and I wanted to love this lens. I gave it every opportunity and it did take a couple of great pictures but, it let me down in the end. The pictures that I took with it, didn't come out as crisp as I expected and maybe that is my fault for expecting so much.
Would be welcome if they could design a flatter lens cap.
You are better off with a nice 35mm prime, or a wide angle / cinema style lens.
).BTW - I agree with others that this lens is a little slow to focus. But focus has been very accurate.
Great lens, really sharp. I am very happy with it. It is easy to put on the camera.I recommend it to others.
Takes good pictures and made using my E-P2 much better. Build quality of the lens is not that great though.
Good lens! I regret why I didn't buy it earlier. It makes my photo looks very sharp. Best lens for NEX-6.
Answer: Yes, it comes with a short cylindrical lens hood (not petal-shaped).
