PhotoRumors Weekly Roundup: Canon Patent, Sigma IBC, Instax Launches

PhotoRumors aggregator post covering several separate stories in one hit, none in enough detail to act on. The Canon patent for high-index glass targeting a RF 100mm f/1.4 and RF-S 65mm f/1.4 is the most photographer-relevant item, but it is a patent filing only. Sigma's IBC 2026 interview touching on the 85mm f/1.2 Art and 20-60mm f/2.8-4 Contemporary is worth tracking separately with a proper source.
