Applying a restriction on weight will limit the overall size and so the objective diameter. Hunting the bush is different from glassing on the tops or the stationary viewing of slips in that the optics are raised to and then lowered from the eyes repeatedly between taking a few paces forward to open up new viewing avenues. It isn't just the raising and lifting. The rotational inertia of heavier binoculars also over time fatigues the wrists. 500grams seems a good upper limit and this unfortunately then excludes 42mm objectives.
FOV is the next priority with the ability to quickly sweep a 180° window out to say 40 metres. As long as the resolution provides a high confidence that a part of a deer that is in view will be identified as such, then that is sufficient. Personally I'd exclude products with an angular FOV much less than 8°. Only a few 8x 30-32mm are engineered in this way. 6.5x or 7x to get a wider FOV is not really a compromise unless a single pair must serve other functions during a hunt.
Like most topics, this has been covered before. Try here for example:

To the OP: as a general rule the folk who have the most to offer on a particular topic will respond to requests maybe once or twice, and then not bother. If your preference is to set up a new request rather than trawling through past threads, then be aware that the overall quality of responses may well decline from what it might have been in the past.
As has been noted elsewhere, the Forum search function isn't the best. Try using Google instead with "nzhuntingandshooting.co.nz" in the search bar and then add additional key phrases — that should get you quickly to the threads you are looking for.
