Do you know anyone seriously into birding, aka bird watching? If so, talk to them about what's popular because that is generally the best informed binocular and spotting scope community there is. Failing that, or in addition, go to a store that carries a selection and try as many as you can. If you're in Southern Ontario, the best store for that is called Wings Over Pelee in Leamington, if they survived covid and the current economy. For $800 you can get a really good bino these days but Zeiss and Swarovski are considered to have the best high end optics there are.
