Canon RF 800mm f/11 IS STM 800mm
Its retractable, locking barrel and gapless diffractive optics deliver an 800mm reach in a 1260g body, making handheld super-telephoto shooting genuinely practical. The fixed f/11 aperture keeps the design compact and affordable, while 4-stop optical stabilization helps maintain sharpness in lower light. This lens is best for wildlife and outdoor sports photographers who need extreme reach without the bulk or cost of traditional fast super-telephotos.
