The Tokina 11-16mm is the sharpest ultrawide I've ever used on a DX Nikon. It's sharper than my Nikkor 12-24mm!
Performance doesn't vary with focal length, which is unusual, and also makes it much simpler to describe.
On a D300
The Tokina 11-16mm is always sharp in the center, even wide-open.
The corners are softer at f/2.8, but not enough to notice in the situations in which I'd be shooting at f/2.8. I only can see it doing something stupid like shooting test charts at infinity in broad daylight at f/2.8.
The corners improve greatly at f/4, which is how this Tokina smokes the Nikon lens at f/4.
By f/5.6 the corners are perfect.
The new Tokina AT-X 116 PRO DX is an ultra-wide angle lens with a fast f/2.8 aperture for better photography in low-light situations. Many photojournalists consider having an f/2.8 aperture a must for any lens in their camera bag.
Based on the award-winning optical design of the AT-X 124 PRO DX (12-24mm f/4) lens, the new AT-X 116 PRO DX has a slightly shorter zoom range to maintain optical quality at wide apertures.
Tokina’s exclusive One-touch Focus Clutch Mechanism allows the photographer to switch between AF and MF simply by snapping the focus ring forward for AF and back toward the camera to focus manually. There is no need to change the AF-MF switch on Nikon cameras** and there is no second AF/MF switch on the lens for Canon, everything is accomplished by the focus ring.
This Tokina 11-16mm lens sets a new standard for speed and sharpness in small-format digital SLR lenses. It's also the fastest ultrawide available for small format digital SLRs.
Its only disadvantages are the potential for incompatibility with present or future features of Canon and Nikon bodies, and the fact that its zoom range is so restricted that you almost should consider it a fixed-focal length lens.
I don't mind the limited zoom range. I almost always shoot these lenses stuck on their widest settings, and only shoot at the longer end when I'm too lazy to put on a longer lens.
Never worry about "missing" a few millimeters of range between this Tokina's longest 16mm and the 18mm common for most midrange zooms. Just walk forward or back half a step.
I'd order a Hoya Super HMC 77mm UV to protect this lens, which at only 4.9mm thick isn't a problem for vignetting on DX or Canon 1.6x. At about $53, it's the best UV filter of which I know at any price. Feel free to go whole-hog and spring $65 for the fancier Hoya Digital Multi-Coat 77mm Protector if you insist.
11mm @ f/5.6
11mm @ f/2.8
Aπό την μέχρι τώρα εμπειρία μου με τον συγκεκριμένο φακό μπορώ να πώ ότι είναι μια στιβαρή και ποιοτική κατασκευή ,εξαιρετικά οξύς ακόμη και με πολύ ανοιχτά διαφράγματα,γρήγορος και οι δε παραμορφώσεις του, λόγω του εστιακού του μήκους, είναι απόλυτα ελεγχόμενες με το ps.Tα χρώματα του φακού είναι εξαιρετικά πιστά και θα τον πρότεινα σίγουρα σαν best buy σε κάποιον που ενδιαφέρεται για φακό σε αυτό το εστιακό μήκος.
Μερικά ακόμη δείγματα του φακού με την canon 50d Εδώ.
