Where is the RF 500mm f/4L IS USM II? Will Canon succeed this lens with a zoom like they did with the RF 100-500mm F2.8L IS USM. The RF 100-500mm F2.8 a zoom, is the successor to the EF 300mm prime. This has Canon Rumors thinking that the EF 500mm f/4L IS USM.
“The most consistent bits of information that we have received suggest that the RF version of the 500mm will also be a zoom in the form of an RF 200-500mm f/4L IS USM 1.4x.”
The RF 1.4 extends the focal length to 280-700mm f5.6; the RF 2X extends the lens to 400-500 f/8, though sharpness falls off significantly with he two times extender. For best results, shooting without an extender is recommended.
The RF 200-500mm f/4L should be priced around $10,000, aimed at professional shooters that need the best possible quality. Find this too expensive, keep an eye out for an affordable fixed focal length 1200mm or 2000mm.
