Buy the camera and lens(es) you can afford. Although DSLRs are still being sold 'new', they've all been discontinued, whether the manufacturer says so publicly or not. You can get a used or refurbished camera for far, far less than buying new. Certainly, don't spend 2024 money on a 'new' camera first released 4+ years ago and now discontinued. Modern camera equipment is all built for extended use, even the entry-level models last for 10+ years. The pro- / semi-pro models are built for heavy everyday use for even longer. Buying one of these models, lightly used, could easily be the first and last body you need, allowing for more money to be spent on lenses.

Here at UHH, the focus is mirrorless full-frame cameras: digital technology marvels with sensors the size of 35mm frames of film. Removing the space needed for a flapping mirror gives options to adapt most every brand's SLR-style lenses onto that mirrorless body -- MILC - mirrorless interchangeable lens camera -- another buyer value of a mirrorless choice.

What brand is up to you. They're not all the same. But, anyone still selling digital cameras in 2024 has to keep up with the intense competition, where anything less than the tier-1 $6000 models is essentially the same in performance and capability. See if you can find a store where you can physically handle a few options, where one might 'feel' better to you than the others.

Handling some models might also help you decide if an interchangeable lens camera is even what you really want / need. A full-frame model is larger and heavier, even before you mount a larger and heavier full-frame lens. What types of subjects interest you? When you hold that camera+lens, would you want to carry that weight around for 4+ hours, even 8+ hours? Would a pocket-sized model, really about the size of a deck of cards, be a better choice? Depending your subjects, a MILC or DSLR might not be what you want or need.
