Question for those who have or have had the EF100-400mm v2 and the RF100-500mm.
My EF lens works well with the R7 body. Just as good as on the 90D. If I would purchase the RF100-500mm, I would assume image quality would be as good or maybe better than my EF lens. My question is, would the native combo give me better IS?
When at airshow with prop aircraft and helos your SS is usually between 1/60 & 320. I am no longer able to pan and have the majority of pics in focus at 400mm and with the t/c it only gets worse. I have resorted to a gimbal/tripod. But that just stinks.
Jets are no problem at this time.

I haven't shot many planes yet with the 100-500, but I haven't seen a big increase in keepers at slow speeds. Still frustrating. The weight does seem to be concentrated a little closer to the camera which might help with smoother panning.
