600mm Big White lens

Canon is reportedly preparing a development announcement for a new 600mm super-telephoto prime, the latest addition to its storied "Big White" lineup. These lenses have long been the go-to tools for wildlife and sports photographers who need extreme reach, fast autofocus, and the image quality that justifies their professional price tags. A 600mm prime sits at the heart of Canon's telephoto range, offering more reach than the 400mm and 500mm options while remaining more portable than the massive 800mm.

Without confirmed specifications or pricing, it's unclear whether this will be an updated RF-mount version to replace the aging EF 600mm f/4L IS III USM, or an entirely new optical formula. Canon's recent RF super-telephoto primes have brought meaningful improvements in autofocus speed and image stabilization, so expectations are high. For now, this remains a rumor best monitored by Canon shooters planning their next big glass purchase.
