Today I took the Canon RF 100-500mm f/4.5-7.1 L IS USM with me for Eastern Water Dragon shots at the Mt Coot-tha Botanic Gardens in Brisbane.
It proved a much more suitable lens than the RF 600mm I used the previous day, due to the closer Minimum Focusing Distance of approx. 1 metre compared to the 4.2 metres of the RF 600mm.
And it was so much lighter, more manoeuvrable and attracted less stares.
Cheers
