Heading out on what appeared to be a fairly bright day, lazy me chose the R7 and RF 100-400mm. There’s no enthusiasm for lugging the heavy gear to a public garden on a weekend, when there will be more bird “photographers” out, among others, than birds.
Halfway there, doom and gloom set in. Without DXO or Topaz, mid-four digits ISO is stretching it on the R7. And that was about as low as I got.
The way Canon and Nikon have a long history of copying each other, it’s hard to imagine that there’s not an f/4 or f/4.5 400mm somewhere in Canon’s pipeline. But not even at rumor stage, and with only a too-short 300mm f/2.8 supposedly upcoming, it looks as though the Sony setup will be getting the call most of the time.
ISO is a bit like reach. There are times when a little bit of reach is all that’s needed to get the shot, and other times when all the reach in the world wouldn’t make much of a difference. But most of us critter-chasers like to set out with as much reach as we can find or are willing to carry. And we’d like enough speed, well, you get the idea . . .
