Kegon Falls (華厳滝)
With stacked filters, 20s.
Kegon waterfall (97m tall) is the only exit for the waters of Lake Chuzenji in Nikko.
Shot taken on the paid platform accessed via a 100 meter deep elevator.
Meanwhile, 70-200mm f2.8 is a lens that I've avoided due to bulk and especially weight, preferring the f4.0 version instead.
Canon has just announced their mirrorless RF 70-200mm f2.8 L USM at under 1.2kg with a really good minimum focus distance of just 70cm (normally 100cm).
Tamron is also releasing 70-180mm f2.8 weighing a mere 815gms for Sony FE. Personally this is the most interesting of all the Tamron f2.8 zooms made for Sony FE. How it renders the OOF areas will be crucial as f2.8 is more useful at this longer range than say 24-70mm, lack of lens stabilization is a negative for this lens type though, even for cameras with IBIS.
