Wow, I think you’re the first person I’ve ever heard of who has been dreaming of a f/7.1 500mm lens. 🤣

weight is an important consideration for me.

I was actually wondering how well the 100-400 tamron would do since it weighed in at 1111g. while this will be obviously heavier because of the fact it's an L and goes to 500mm. it should still be considerably lighter than a corresponding F4-F5.6 which would put it both monetarily and weight wise out of my justification and the difference between f5.6 and f7.1 is only 2/3's of an EV. you can EC -2/3's of a stop and get the same shutter speeds but less weight.  yes, you lose on DOF .. shrugs.
