The honeymoon . . .

. . . with the RF 100-400mm lens should have been over a few weeks ago. After all, even pro-level lenses never survive more than a couple of weeks of scrutiny without me finding out their deepest, darkest secrets.

Other than what was known when it was acquired, that its max aperture is slow and it’s not weather-resistant, the lens has been great without regard for price, spectacular when its price is considered. Even with the RF 1.4X extender.

Shooting known targets today, first such outing with this lens since my swampy scrub patch is presently a lake, I see that It’s the only zoom/extender combo I’ve used that outperforms the R 80-200mm + APO 2X. It totally buries the leaden Lumix S Pro 70-200mm, both the f/4 and the f/2.8.

On top of it all, lens, extender, and R6 combined weigh in at a very manageable 1536g. No wonder the EF and Sony setups have been getting so much rest in the dry cabinet.

Wonder how it’d look at f/16 . . .
