Yes, I just put the strap over my should and let them hang down from there. They sit comfortably from there if I am not moving fast. I can hold them with my left elbow against the body if needed. If I have to move fast or walk some distance, I put the strap from the shoulder over my head as well with the strap across my chest, when they sit high under my left arm which is quite comfortable. I have never been a fan over putting the strap over my neck - the weight on the neck gets rather unbearable after a few hours - also you have to hold them with one hand if you are walking fast.

Regarding depth of field, this was really brought home to me when I bought the 12x50s. There is just a slither in focus and you only had to move the focusing wheel a millimetre or so for it to go out of focus. Comparing it in a photographic sense, it was like using f2 with the 12x50s as against f16 with the 7x42s. I would be sure that it is not mistaking field curvature for depth of field.

Lloyd, when you say you sling them over your left shoulder, do you mean they 
hang straight down from there, or is the strap diagonally across your chest so 
the binoculars are on your right side?

I also find interesting the comments you and several others have made about depth of field. I've read many arguments about this in other forums, with some saying they can't see how manufacturers can really vary it.
Some claim that people are mistaking field curvature (if that's the right term) 
for depth of field. I.e. The focus distance is closer to the observer at the 
edge than in the centre of the view. If that's the case then the most expensive 
pairs with a flat field would have the worst apparent depth of field.

I haven't owned or tried enough pairs to know if this is correct. All mine have 
been very curved.
