Hi, I checked and there is no firmware update for the 150-600mm except for a teleconverter they sell. I ordered the 60-600mm to see if it makes a difference with a more recent lens. I would get the new Canon RD 100-500mm but really don't want to lose the 100mm on the long end and one stop down in aperture. I really like the Sigma performance.

The RF 100-500's F7.1 is only 1/3 stop below the Sigma's F6.3, not one full stop.

If you're shooting in plenty of daylight I would have considered the 800 F11.
