An RF mount fisheye zoom is coming to the Canon lens lineup and is set to be similar to the EF version for DSLRs. Like all RF lenses, it will fit both full-frame and APS-C sensor cameras making it a worthwhile purchase for anyone, even if you’re considering upgrading your system in the near future.
Typically, fisheye lenses are usually wide-angle prime lenses that produce a strong visual distortion so a zoom fisheye is certainly a niche product. The EF mount Canon EF 8-15mm f/4L USM was released over a decade ago and allowed users to shoot circular or full-frame images. Being a zoom lens, it was a lot more versatile than any other fisheye lenses available and for many years was the only zoom fisheye lens available (until Nikon launched the Nikkor 8-15mm AF-S f/3.5-4.5E ED lens in 2017).
