Tokina'southward recently released SD 17-35mm f/4 AT-X PRO FX lens is designed for Nikon and Canon cameras with 36 x 24 mm sensors but tin can also be used on Canon and Nikon bodies with APS-C sized sensors. Offering a 2x zoom at moderately wide angles of view, it'south one of a series of wide-angle zoom lenses the company produces.

Photographers with a Canon or Nikon DSLR with a 'total frame' sensor will find the Tokina 17-35mm competes with the Canon EF17-40mm f/4L USM and AF-S Nikkor 17-35mm f/2.8D IF-ED lenses respectively. Primal specifications of the three lenses are provided in the table below.

Like the Tokina AF xvi-28mm f/ii.viii AT-10 Pro SD FX lens we reviewed recently, the 17-35mm f/four is larger and heavier than similarly-specified ultra-wide bending lenses for cameras with APS-C sized sensors. Information technology'south as well a fleck more expensive. Nikon owners are likely to find information technology especially attractive because it'southward less than one-half the price of the Nikkor equivalent.

Although information technology doesn't cover such a wide angle-of-view equally the 16-28mm lens, the 17-35mm f/4'due south zoom range is marginally longer (2x vs ane.75x). A full f-cease slower than the xvi-28mm lens, it's too roughly twoscore mm shorter and 350 grams lighter.

The optical design consists of thirteen elements in 12 groups and includes one aspheric glass element plus two Super-Low Dispersion drinking glass elements to minimise aberrations. Dissimilar the 16-28mm lens, the front element is recessed into the lens barrel and threaded for 82 mm filters (which are usually pricey). Both focusing and zooming are internal, which means the barrel length remains constant and the filter mount doesn't rotate.

Like the 16-28mm lens, this lens lacks stabilisation only well-nigh users should discover information technology easy to hand-hold at relatively wearisome shutter speeds. A petal-shaped lens hood is provided, forth with a large, clip-on front cap and bayonet-mounted rear cap.

Build and Treatment
Build quality is similar to the 16-28mm lens, with which the 17-35mm f/4 shares many features. Among them are the well-made, largely plastic lens barrel and metal mounting plate. Weatherproof sealing is as well provided at the lens mount and the overall associates is  tightly controlled.

The review lens carries the standard distinguishing thin golden band, which encircles the lens approximately 5 mm behind the front of the barrel.  Information technology handled as well on the ii camera bodies we used for our tests: the Catechism EOS 5D and EOS 5D Mark II.

The front of the lens butt is wide enough to prevent your fingers from straying into the picture and its inner edge is deep enough to adapt filters up to about half-dozen mm thick without  vignetting. The forepart element is recessed almost 10 mm into the lens barrel and measures approximately fifty mm in diameter.

The lens barrel narrows slightly 15 mm from the front, stepping down to a 20 mm wide focusing ring. A 16 mm broad rubber-coated grip with 3 rows of rectangular dimples covers nigh of it, aligned with the leading border.

The aforementioned One-touch Focus Clutch Mechanism  as used on the xvi-28mm lens is featured on the 17-35mm f/4  lens. To switch between AF and MF modes, you simply snap the focus ring forward for AF and back towards the camera to focus manually. The ring turns through approximately 75 degrees in MF mode.

Just behind the focus band  the lens barrel is marked with AF and MF lines. Beside these lines is a recessed distance scale that clicks in for transmission focusing way.  It has v settings in metres and feet, ranging from 0.28 metres to infinity.

The 25 mm wide zoom band located just behind altitude calibration has a 17 mm wide band of thick, parallel safe ridges running up to its leading border. Five focal length settings (17mm, 21mm, 24mm, 28mm and 35mm) are stamped on the abaft edge for lining upward confronting a marker on the fixed department of lens butt but in forepart of the lens mount.

The zoom ring on the 17-35mm f/4  lens wasn't quite every bit stiff as its equivalent on the 16-28mm lens merely still very well damped. It rotates through approximately 45 degrees as you bridge the focal length range.

Performance
We carried out our Imatest tests on this lens using the Catechism EOS 5D body, which is the body we use for all assessments of 'full frame' lenses. Even so, to evaluate general functionality, many of the test shots were taken with the lens on an EOS 5D Mark II torso.

The AF motor in the 17-35mm f/4 lens was a little noisier than the motor in the 16-28mm f/ii.eight lens and perceptibly louder than the ultrasonic motors in Canon and Nikon lenses. The dissonance of this motor would probably be picked upwardly on movie sound tracks, particularly in quiet environments.

Imatest showed the lens to be a very good performer on the whole, with centre resolution exceeding expectations at all only the widest focal length setting. Best performance for most focal lengths was betwixt f/4.5 and f/8. The graph below showing the results of our tests is based on JPEG files from the EOS 5D.

The sugariness spot for this lens is around 20mm at f/4. Edge and corner softness were credible up to f/viii with the 17mm focal length and betwixt f/4 and f/6.7 for other focal lengths. Diffraction kicked in at around f/11.
Lateral chromatic aberration remained mainly in the 'low' band, kicking up into 'moderate' at f/4 with the17mm focal length and down into 'negligible' for the middle of the aperture range at 35mm. Traces of coloured fringing were found in some test shots. In the graph below, the red line marks the edge between 'negligible' and 'low' CA and the dark-green line separated 'low' and 'moderate' CA.

Equally expected, barrel distortion could be seen at the 17mm focal length, although it was less than we expected for such a broad angle of view. By 21mm the distortion was much less visible and it became quite difficult to detect from 24mm on.

Vignetting was also quite low for a lens of this type, although some corner fall-off was visible in shots taken at 17mm with the f/4 maximum discontinuity. By 24mm very little corner darkening could exist seen. Unlike the 16-28mm lens, we plant no show of centre-of-field concealment at 17mm.
Flare and ghosting were also much less than nosotros institute with the 16-28mm lens, even when the dominicus was but outside the frame. Close-up performance was like to the sixteen-28mm lens.

Purchase this lens if:
– You're a Nikon FX DSLR possessor who wants an ultra-wide bending zoom lens for a reasonable cost.
– Y'all require superior performance and build quality.
– You want a broad-angle lens that accepts filters.
Don't purchase this lens if:
– Yous apply a DSLR with an APS-C sized sensor.
– You require a lightweight lens.
– You want to shoot close-ups.
