Tokina AT-X M100 AF Pro D 100mm f2.8 Nikon mount lens review: Excellent all-round performanceBy Kevin Carter - Tuesday December 10 2013 Lens Review
Although not a new lens we’ve had the opportunity to test the Tokina AT-X M100 AF Pro D in Nikon mount, a dedicated macro lens complete with a manual aperture collar. Manual selection of the aperture is an important feature with Nikon users as it allows unrestricted use with extension rings. Read on to find out how well it performs.
When Nikon followed rival Canon and removed the aperture collar on their G-series lenses, the firm overlooked updating their range of extension rings with the necessary / crucial CPU contacts. This is a perplexing situation for hardcore macro enthusiasts looking to achieve magnifications in excess of 1:1 life size, as when attached to Nikon made extension rings the G-series Micro Nikkor lenses can only be used at full aperture.
Perhaps that’s why Tokina has left this full-frame model untouched. As AF-D type lens it has a aperture collar like those older Nikkor models and yet has modern coatings to reduce flare and ghosting from internal reflections most notably from the sensor’s surface.
Although it doesn’t have any ED glass or stabilization it’s a well-built metal-barreled lens intended for professional use. It has 9 elements in 8 groups that focuses down to a 0.3m (1 foot) minimum at 1:1 (life-size) magnification, weighs 540g (1.19 lb) and costs a not unreasonable $449.
