some more thoughts that might confuse I mean help you 😇
if that's the case and you are primarily using binoculars to spot for photo opportunities, a lightweight/smaller binocular becomes more compelling. I also think (and opinions may vary here etc depending on your ability to get closer to the bird once found) that as the effective range at which you will get a good photo (this assumes you are trying to get good shots, not just record shots) is actually pretty short, a binocular with lower magnification eg 8x means that what you find in your binoculars is more likely to give you a good image. If I was lugging along a camera and my intention was to photograph birds I suppose I would bring a binocular along for spotting, but I think it would be something small and handy eg. 8x32 or 8x30.
for pure birding - 10x vs 8x - you can make a case for both mags, and a lot does depend on you yourself - for instance my brother is quite happy using 8.5x for everything, but I prefer 10x when targets are further away. I do recommend giving high quality examples of both magnifications a good trial, as 8x has some real advantages - larger field of view and greater steadiness amongst them.
It's worth having a real good look at secondhand examples of older Zeiss, Swarovski, Leica etc. as their mechanicals are very solid, the companies will likely service them for a long time to come and optically they are still pretty good to very good (Zeiss FLs, later Swaro SLCs). If you plan to be using them hard, or intend to keep/use them for a long time, solid mechanicals and durability can count for more than a few % more light transmission, or the most neutral colour rendition etc.
I am definitely more of a photographer than a birder
