Just get Vortex or Maven. Both have a, you break it, we fix it warranty. You're going to get a lot of pseudo chads here that say to use 15x and other shit.
Most people can comfortably hold 8x binos, but 10x start losing clarity to shaking with the zoom it gives. A bipod, monopod, or resting against the arms of a chair, ledge, or tree can help stabilize this. Beyond 10x and I think less than 50% can hold a 10x stable enough to get its advantages, you need stability of some sort.
It depends on what you are using it for too. Some people like to bring cheeky shit, because it lets them see whether their deer has mange or is a 12 point, but it is also a lot of extra weight.
Last you have the more modern designed binos in your picture. They are more compact, and more expensive. Roof prisms. The older design that is wider, or the porro designs tend to be cheaper.
Also, it is worth adding that field of view plays a bigger part than people say. The higher the zoom, the less wide it will be. I also think roof prisms tend to be less wide.
Last bit is the second part of the equation. The number past the x, so like 8x50. The second part is how much light they let in for settings like dusk. I think porro designs don't need as much light as roof prisms, and this also affects the weight of the binos.
Also, most binos don't work well with glasses in my experience. Vortex's overall havent been good. I usually just adjust it to looking without glasses and just pop them up, but if this is important to you, read the reviews.
I use Raptor 8.5x32 (porro) $125
And Diamondback 12x50 (roof) $250
I could just as easily use 10x50. If the second was porro, i'd probably just use those as I don't like stabilizing my arms using roof prisms. But I don't use them backpacking either as I do as a lookout.
I had $400 Mavens and when I started the job also bought a spotting scope. The Mavens were better, but didn't offer enough benefit for the price tag, the fov was less, and the view hold was too wide
