I'm not a neck strap person.
There are times, of course. If you need your hands free then it's no good using a wrist strap. You can't climb a ladder with a camera hanging off your wrist. And if you're trying to negotiate yourself into a small boat....
In my LX3 and GF1 (EVF free) days, the neck strap was a plus. Holding the camera far enough out to tense the neck strap stabilised the camera — good for a stop or two. With a camera that has an EVF, however, I get the same result by holding the camera against my head.
The short version is that now I'm a wrist strap fan.
This is only possible because I'm not carrying the "big iron." If I was a wedding photographer I wouldn't fail to have full-frame Nikons or Canons; and I'd be using neck straps because I'd be carrying more than one camera — and you can't do that with a wrist strap. (And I'd want my clients to know that I'd invested heavily, and those neck straps would scream my chosen brand.)
As I walk along, my mirrorless camera on a wrist strap doesn't scream, it whispers. Subjects don't see that camera until it's up and shooting, and then it's gone again. And with a camera on a wrist strap, when your arm is down the strap takes most of the weight of the camera; so you can carry it all day long.
Other wrist-strap advantages include:
- The camera fits into the bag more easily.
- Because I use a strap that attaches to the tripod mount, it's secure, but detaches easily'
- There're no straps in the way when the camera is on a tripod.
- When the camera's on a neck strap, some EVFs read your chest as your face and keeps the camera active; reducing battery life.
