Test drive of an upgrade from mkII to mkIII 1.4x TC. Bit of an extreme test, due to low light levels on the winter solstice pushing ISO of some shots to 25,600!
Looking for autumn colours…
A spring visit (2nd set) and a winter visit (1st set) – the latter trying out the new Canon EF 100-400 mkII.
Taken at the Royal Botanic Gardens, Edinburgh.
