Canon has taken care with the optical design, using two aspherical elements, an ultra-low dispersion element, and Super Spectra Coating to minimize aberrations and reduce ghosting and flare. The small form factor and 5.9" minimum focus distance make it useful for intimate portraits in tight spaces. The built-in image stabilizer will also work with Movie Digital IS in compatible bodies like the R50 V. Additionally, the lead screw-type STM AF system is fast enough to keep up with speedy continuous focus while being smooth and quiet enough to work for video.
