Might have as much as $1600, but the more saved the better. Also need a lens.
Sony A7r - $434 (well used condition) Sony A7r II - $949 (like new condition) Sony A7r III - $1299 (excellent condition)
Looking at mpb.com. Are the features and improvements worth it for each iteration?
I enjoy urban/street night photography, urban decay, landscapes, and want to get in to portraiture.
EDIT: I have also, and would still, consider a Panasonic LUMIX S5, or a Fujifilm X-T5.
Worth considering the other A7 lines too, just because you mention night photography.
For example, I know the main differences between the A7r iii and the A7 iii are the obvious one, the A7r has double the pixel resolution, but less obviously, it also has a reduced maximum ISO compared to the A7. Given that’s 30,000 ISO vs 51,200 ISO (and up to 204,800 expanded ISO) at the levels we’re talking about might not matter for what you’re trying to shoot, but it’s worth considering.
That IS interesting, and I had not considered it
