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.
I’ve been very surprised what I can do hand held in fairly low light with simply a fast lens. Yeah, for super dim lighting you’re still going to need high ISO or a really long shutter speed, but for even moderate lighting that you’re likely to get in an urban environment I’ve taken many a photo with sub 4k ISO and a 1/125 shutter.
