>>4131019>you can't shoot indoors without a flash because...I JUST CANT OKLol, crop sensors. If you want to lose that much detail to noise the computational photography of your iPhone will get the same results. You're just going to resize it to less than 16mp and save as a jpeg with 90% quality anyways, right?
APS-C only ever existed for economics reasons. Sensors were expensive to manufacture early on, so full frame actually came on the market second as the high end option.
Today you can buy a Nikon D800e, a stellar camera, for $600 on ebay, and the older lenses are largely under $500. Nikon's used lens market just crashed because over half of it can't work on their mirrorless cameras. Or you can go for the mirrorless meme with more versatile autofocus. A Sony A7RII is $700-800, and a sony A7RIII is $1000-1300. Not cheap but on the other hand, guess what people sell inferior crop mirrorless bodies for? Even with lenses, the prices come pretty close.
Sony A7RII - $700
Sony A7RIII - $1150 if you get an ok deal
Three super sharp primes for a sony, because if it aint sharp a phone is going to embarrass you:
Sony FE 20MM F1.8G - $400
Sony FE 40MM F2.5G - $650
Sigma A 105 mm f/2.8 DG DN Macro - $800
$1850 total
Fujifilm X-T4 - $1000
X-T5 or X-H2 - $1700-1800
Three super sharp primes for fuji X mount, because if it aint sharp a phone is going to embarrass you:
Fujifilm Fujinon XF 16 mm f/2.8 R WR - $350
Fujifilm Fujinon XF 23 mm f/2 R WR - $350
Fujifilm Fujinon XF 80 mm f/2.8 LM OIS WR Macro - $800
(Note: "super sharp" but these lenses have to resolve that detail onto a smaller sensor, so the tiny, packed in megapixels are just resolving the blur better and it falls apart fast in low light)
If you don't have money... just save up for a full frame DSLR, or use your phone.
