Tokina has focused most of its attention on wide-angle lenses over the years, earning a good reputation in this sector of the market. Surprisingly, then, the first lens in the new series of Opera lenses was a Tokimãng cầu Opera 50milimet f/1.4 prime, but the second is a direct replacement for the popular ATX 16-28milimet f/2.8 Pro wide-angle zoom for full-frame Canon và Nikon SLRs.


Tokimãng cầu says the kiến thiết ethic behind Opera lenses is that they’re ideally matched lớn the lakiểm tra high-over, high-resolution SLRs, inspiring photographers to create ‘works of art’. As such the new 16-28milimet is aimed squarely at enthusiast photographers, with Tokina’s typically sturdy và robust build unique, along with a fast & constant f/2.8 aperture rating. The metal mounting plate is weather-sealed and the bulbous front element is protected by a permanently fixed petal-shaped hood.






The optical layout is based on 15 elements in 13 groups. Of these there are three glass-moulded aspherical elements, including one large-diameter precision-molded element, second from the front. Towards the rear, three low-dispersion elements are featured with the ayên of reducing both lateral and spherical chromatic aberrations.


As with the older AT-X Pro lens, the opera’s autofocus system is based on a "silent" DC motor coupled with a GMR (Giant MagnetoResistance) magnetic sensor. Tokimãng cầu says the GMR sensor has been updated for increased tốc độ and accuracy – we didn’t notice any real boost in speed, và autofocus remains slower than in competing ultra-wide zooms that feature ring-type ultrasonic or stepping motor systems. However, autofocus proved more consistently accurate in our tests.


The new lens retains Tokina’s usual ‘one-touch focus clutch mechanism’. This enables you lớn snap the focus ring backwards and forwards to switch between manual focus and autofocus respectively. It works well enough, but many prefer the full-time manual override facility generally available with ring-type ultrasonic and stepping motor autofocus systems.


Distortion is fairly low even at the shorchạy thử zoom setting. Vignetting is minimal if you narrow the aperture khổng lồ f/5.6

Tokimãng cầu Opera 16-28mm f/2.8 FF: Performance

Image chất lượng is very good overall. At the short end of the zoom range, centre-sharpness and contrast are fabulous even when shooting wide open at f/2.8. At mid to lớn long zoom settings, centre-sharpness is similarly excellent if you stop down to lớn f/4, although corner-sharpness is less impressive throughout the entire zoom range.

Vignetting is fairly low for such a wide-angle, wide-aperture lens &, again, peripheral illumination is much improved when narrowing the aperture to lớn f/4. Distortions và color fringing are well controlled across most of the frame, but magenta and cyan lateral chromatic aberrations can be quite noticeable towards the corners of images.

Overall performance is less impressive than in the Sigma 14-24mm f/2.8 DG HSM Art & Tamron SP.. 15-30milimet f/2.8 Di VC USD G2 lenses, both of which offer a wider maximum viewing angle while equalling the Tokina’s f/2.8 aperture rating. Even so, the Tokimãng cầu is much less expensive sầu khổng lồ buy & excellent value at the price.


At the long over of the zoom range, the short minimum focus distance and wide f/2.8 aperture enable background blur

Tokimãng cầu Opera 16-28mm f/2.8 FF: Lab tests


Centre sharpness at 16mm is great, from wide open through khổng lồ f/11. As you zoom in, the lens struggles to lớn maintain the same cấp độ of sharpness at f/2, but there are no problems at f/4 and beyond.


Inevitably for such a wide-angle lens, corner-frame sharpness is well below centre-frame sharpness. This is largely due khổng lồ the distance between the lens and the centre of our thử nghiệm chart being significantly shorter than the corners, owing to lớn the lens needing lớn be positioned very near khổng lồ the chart khổng lồ maintain proper framing at such a short focal length. Combine this with a large lens aperture and the corners of our test chart will be slightly blurred due to the shallow depth of field. However, even accounting for this, the Tokina Opera 16-28mm could score better for corner sharpness, especially at 16milimet.


We"d expect some fringing from a wide-angle lens, và the Opera 16-28mm is no exception. At 16milimet aberrations are quite visible at the edges of frame, but they bởi become a bit less noticeable as you zoom in, due khổng lồ the less severe angle that light is entering the lens barrel relative sầu khổng lồ objects on the periphery of frame.


Barrel distortion is significant at 16milimet, resulting an obvious bulging effect that"s particularly noticeable when shooting geometric subjects. Fortunately this quickly diminishes at 20milimet, và by 28mm the lens produces an essentially distortion-không tính tiền image.

Tokimãng cầu Opera 16-28milimet f/2.8 FF: Verdict

This second lens in the Opera line-up has a robust build & delivers very good image unique, but it’s not a dramatic improvement over Tokina’s older ATX 16-28milimet f/2.8 Pro lens. The lakiểm tra competing Sigma 14-24milimet f/2.8 Art & Tamron 15-30mm f/2.8 G2 zooms perform better, but the Tokina is only about half the price lớn buy.

Autofocus is neither as quick nor as quiet as in competing lenses with ring-type ultrasonic drive sầu, và some may prefer the constant manual override offered by its rivals. Again, though, the new Opera delivers impressive sầu overall results và offers great bang for buck.
