I would really like Canon to make a big brother for the RF 100-500mm. By using the "same" design with 105mm filter / glass size they could probably make the following:
120-600mm f/4 - f/6,3 (actually ~f/6,1 which they could for marketing purposes call f/5,6 when using 1/2 stop increments)
f/4,0 _ 120 - 186mm
f/4,5 _ 187 - 314mm
f/5,0 _ 315 - 449mm
f/5,6 _ 450 - 584mm
f/6,3 _ 585 - 600mm
This would probably weigh about 2200-2300g (+tripod collar ~200g) so still not overly heavy for being really close focusing (~144cm / 56,7" at 600mm) and brightest in its class.
For me all of those focal length / aperture combinations would be very usable (to get nice DoF for varying situations).
Also, would be nice to have an option to buy it with a factory selected (individually fitted) 1,4x TC, resulting ~840mm f/8,5.
What do you think? Would any of you find this kind of a RF lens useful?
