There are two lenses you need for nature photography, anything to do with critters specifically, a long lens and a macro.
The beauty of one lens I have, is they are the one in the same.
In a recent school camp, I pressed my 300 f4 into service from minute one (literally). Straight out of the car, about a half hour before the main group arrived, I grabbed the 300 and had a poke around.
Devilish light, but needs must.
Sparrows, Bumble and regular bees, some flower heads and abstracts, all hand held, all without changing anything except the focus limiter on the lens.
Sometimes I did not use it when I should have (did not have it), like the little snake above, shot with a standard lens! Not clever as these can be lethal, even when tiny.
From 4” to 4’, this one required more common sense, but without the 300, I pressed the 150 IRIX into service.
A much neglected lens, the 150 IRIX was also used, but compared to the 300, everything was harder.
I managed to get a bee in flight, but compared to the 300, this was more luck than AF assisted fun.
