Lens Test: Tokina AT-X 80-400mm f/4.5-5.6 AF D
Distance shooters and filter fans get an internal-focusing powerhouse zoom.
HANDS ON: With all-metal construction and a heavy, rugged feel, it has a nonremovable tripod collar and a zoom lock that holds it at its most compact size for transport. Its new felt-lined lenshood incorporates a spring-loaded “PL Assist” wheel that allows you to reorient lensmounted filters without removing the hood. The zoom action is stiff; the manual focusing action seems underdamped.
IN THE LAB: SQF data were about average for a long tele zoom, with results in the Excellent range at 80 and 135mm. At 200mm, image quality fell to Very Good, and at 400mm to Good, a significant improvement over Tokina’s first version of this lens. In DxO Analyzer 2.0 tests, it showed surprisingly good distortion control, with Imperceptible barrel distortion at 80mm (0.02%) and Slight pincushion distortion at 135mm (0.22%), 200mm, and 400mm (both 0.29%), another improvement. Edge vignetting, while disappointing, was still better than before, especially at 200mm. Light falloff was gone by f/8 at 80mm, f/9.5 at 135mm and 400mm, and by f/13 at 200mm. At the uniform close focusing distance of about 8.5 feet, maximum magnification ratios ranged from 1:28.5 at 80mm to 1:5.43 at 400mm.
|What’s Hot Ruggedly constructed. Minimal distortion. What’s Not Canon and Nikon mounts only. Heavy.|
CONCLUSION: With the right focal length range for distance (think wildlife and sports), this lens is unusual for being about the only 80-400mm zoom that isn’t image-stabilized.That makes it much less expensive. If you’re on a limited budget and want a sharp, well-built, tele zoom, give this lens a look, especially if you’re a big filter fan.
