SIGMA releases new firmware for the 500mm f/4 DG HSM OS, improves efficiency with R5 and R6 | Canon Rumors


A 500mm f/5.6 in EF or RF could be an unbelievable lens!

I’m really shocked Sigma or Canon hasn’t developed one. IMO a 500mm f/4 is for a really severe photographer, however the f/5.6 might be a lot lighter, extra inexpensive, and would enchantment to a wider vary of customers, together with professionals who must hike into areas for wildlife functions.
