Was up in Canmore/Banff and met up with Jonathan and his wife - lovely dinner and great conversation.

In discussion about lenses, he offered up the special quality of the super tele's and F4 vs. the 100-500 at 7.1.

Well as my luck seems to have turned for the better, it looks like I will have a decent lump of cash coming in and the rumor of the RF 200-500 f4 (an extra 100 over the EF predecessor) has me pondering...... JH also tossed the 100-300 2.8 into the mix with a set of TCs and that would likely bus several thousands USD less than the 200-500 AND provide 2.8 at 300! A very flexible and power combo (assuming IQs are roughly equivalent).

I am asking for (not that anyone on this forum is shy) for opinions. Swapping out my EF set to RF and 15-35, 24-105 (2.8?), and then the long end question of 200-500 or 100-300 with TCs.

Thanks for the thoughts.

Mike
