How to Choose a Camera Body

Faced with the wall of model names and acronyms in camera shops, choosing a camera body can quickly become discouraging. Yet a few simple criteria are enough to settle the essentials — and ignore the rest.

DSLR or mirrorless?

DSLRs, with their mechanical mirror and optical viewfinder, remain rugged and benefit from a huge pool of second-hand lenses. Mirrorless cameras, more recent, do without both: they’re more compact and lighter, with an electronic viewfinder that shows a live preview of the exposure — a real advantage when you’re starting out. Today, nearly all new development is focused on mirrorless across every manufacturer: all else being equal, that’s the direction the entire market is heading.

The sensor: full-frame or APS-C

A full-frame sensor gathers more light, delivering better low-light performance and more pronounced background blur at the same aperture. An APS-C sensor (smaller) is nonetheless perfectly sufficient for the vast majority of uses, with lighter and cheaper bodies and lenses. Full-frame mostly makes sense for professional work or demanding low-light shooting — not as a prerequisite for getting started.

Megapixels, less decisive than you’d think

Beyond a certain threshold (20 to 24 megapixels), extra megapixels don’t improve the perceived quality of a photo for everyday use (online sharing, standard prints): they mostly inflate file sizes and storage needs. A more recent sensor with fewer megapixels but better digital noise handling will often deliver better real-world results than an older, very high-resolution one.

Ergonomics, the criterion nobody remembers to test

A body with excellent specs on paper but that doesn’t sit well in your hand, with buttons awkwardly placed for your fingers, will remain a chore to use every day. Before buying, pick the camera up in a shop — check the weight, the access to the main controls, the comfort of the viewfinder — and you’ll avoid plenty of disappointments no spec sheet will ever reveal.

The real advice: the body matters less than the lens

Two recent mid-range bodies produce, in the vast majority of situations, very similar results. It’s the lens that has the biggest influence on how a photo ultimately looks — see choosing the right lens for what you actually shoot. A decent body paired with a good lens is often a better investment than a high-end body fitted with the entry-level kit lens.
