- Uses LED lights first seen on EOS M macro lens
- Weighs just 6.7 ounces and is less than 2 inches long
- True macro lens, offering 1:1 reproduction
Canon has borrowed from its mirrorless EOS M system in announcing its latest lens – the Canon EF-S 35mm f/2.8 Macro IS STM.
As its name indicates, this is a macro lens for Canon’s EOS DSLRs with APS-C sensors, where it becomes a full-frame equivalent 56mm.
Like its EOS M-system stablemate, this lens has small LED lights on either side of the front element. The intensity of the lights can be adjusted, and the photographer can use one, both or neither of the lights. The lights are turned on and off by a barrel-mounted button.
The lens uses 10 elements in six groups and includes one glass-molded aspherical element. The aperture is formed by seven blades. The weight of the lens indicates that composite elements are used, similar to Canon’s other consumer-level lenses.
The EF-S 35mm is a true macro lens with 1:1 reproduction and can focus as closely as 5.1 inches (13cm). The lens accepts 49mm filters that are screwed into the unusual lens shade that entirely blocks light from the LEDs. This prevents reflections from the macro lights reflecting off of a filter and then back into the front lens element.
The lens is image stabilized, using Canon’s Hybrid IS system. Canon’s Smooth Movie Servo AF and Lead Screw-type STM for autofocus, making it suitable for video. In addition to its autofocus capability, the lens also can be manually focused at any time.
This is a compact lens that is just 2.7 x 2 inches (69.2 x 55.8mm) and weighs 6.7 ounces (190 grams).
The lens will be available for US$349.99 in June 2017.
