Canon has announced the RF 16-28mm F2.8 IS STM, a fast wide-angle full-frame zoom that's meant to be a more budget-friendly option for people looking to shoot photos and videos. The lens is lightweight and compact, coming in at a very similar size and weight as its sibling, the RF 28-70mm F2.8 IS STM.
The 16-28mm is explicitly designed to pair with that lens for enthusiasts wanting constant F2.8 capability on a budget.
The lens' optical formula includes 16 elements in 13 groups, with 2 aspherical lenses and 4 UD elements. Like many of Canon's RF lenses – including its higher-end L-series models – the 16-28mm uses of digital corrections as part of its design. At its long end, it has a minimum focusing distance of 0.2m (7.9"). The lens is weather sealed to provide some protection against dust and moisture, though there aren't gaskets on all of its various buttons, switches and rings.

As its name implies, the 16-28mm F2.8 IS STM uses a lead-screw type stepper motor for focusing, which the company says will provide "fast and accurate" focusing. It also features optical image stabilization, rated for 5.5 stops of compensation at the center of the lens, which gets bumped up to 8 stops when paired with a camera body that can coordinate its sensor stabilization with the lens'.
The lens weighs around 445g (15.7oz) and is 91mm (3.6") long when retracted. It uses 67mm filters and can be paired with an EW-73E lens hood, though it is sold separately.
The 16-28mm F2.8 becomes Canon's fourth wide-angle option, sitting between the $550 RF 15-30mm F4.5-6.3 IS STM and the $1400 RF 14-35mm F4 L IS USM. The new lens has better weather-sealing than the variable aperture zoom but, is less well-sealed than the slower-but-wider F4 'L' series lens. Above all of these sits the $2400 15-35mm F2.8 L IS USM.
The RF 16-28mm F2.8 IS STM will retail for $1149 and starts shipping on February 11th.
