Canon patent shows off ultra-fast, ultra wide 14-21mm F1.4 RF lens
Canon hasn't been shy about the improvements and flexibility its new RF mount affords lens designers, but if a recent lens patent ends up coming to fruition, it might just be the most interesting RF lens we've seen yet.
U.S. Patent Publication Number US 2018/0314060 details the optical design for an RF 14-21mm F1.4 lens, an ultra-fast, ultra-wide-angle lens that will inevitably have astrophotographers picking their jaws off the floor.
As with all patents, there's a good chance the lens design will never make its way past the drawing board, but recent rumors suggest this very lens could be amongst the RF lenses Canon will be announcing in 2020.
Canon assured us the new RF mount would lead to unique lens designs — this may very well be one of the designs it had in mind.
