24-105 f2.8. Seems roughly the same size as the 100-500.

I think if I sell off all the gear sitting on the shelf I can get close to the 3k needed.

What I am penduluming on is the IQ from the 70 to 105 range. It would appear to be sunstantively better than the f4.

I am thinking with the R5 resolution, my 70-200 (which hasnt been on the R5 since the 100-500 showed up) is on the block.

15-35, 24-105, 100-500, quite a ramge in 3 lenses.

The super super long ehhhh dont have an answer there. I might have to rely on a rental when I am thinking of going super long.
