Camera Bodies — FocalMath

90 camera bodies across Canon, Nikon, Sony, Fujifilm, Panasonic, OM System, Olympus, Leica, Pentax, and a handful of drone and action-camera sensors — a bounded, curated set of genuinely popular bodies, not an attempt to catalogue every camera ever made.

Bodies are grouped by brand below for easy browsing, and each one links straight to its own reference page with the real numbers this site's calculators actually use, including resolution, sensor format, pixel pitch and circle of confusion.

Every camera page lists its real sensor format, its real published resolution, and two numbers derived from those: pixel pitch (how large each individual photosite is, in microns — smaller pitch generally means more resolution packed into the same sensor area, which matters directly for the astro NPF-rule calculation) and circle of confusion (inherited from the camera's sensor format, and used the moment you select that camera's format in the DoF calculator). A subset of the most iconic and heavily searched bodies get a fuller writeup covering what makes that specific camera notable; the rest carry the same real, computed spec data at a shorter, denser page — the numbers are the content there, not padding around them.

Don't see your exact camera? Every camera in this reference shares its sensor format with several others — find your camera's sensor format (usually printed in the manual or the manufacturer's spec sheet) and use the matching sensor page and the calculators directly; the physics don't care which body the sensor is bolted into.

Why Resolution and Sensor Size Are Tracked Separately

It's tempting to think of a camera as one combined "quality level," but resolution and physical sensor size do genuinely different jobs in this site's calculators. Sensor size drives crop factor and circle of confusion, which feed the depth-of-field and hyperfocal calculations. Resolution, combined with sensor size, determines pixel pitch, which feeds the astro NPF-rule calculation and the print-size math. A high-resolution APS-C camera and a lower-resolution full-frame camera can have very different depth-of-field character (driven by sensor size) while having surprisingly similar pixel pitch (driven by the resolution-to-sensor-area ratio) — two cameras that look similar on one axis and quite different on another, depending which number you're actually asking about. Keeping the two ideas separate in your head is worth more than memorizing any specific camera's numbers, and it's exactly the distinction the blog's piece on the megapixel myth explores in more depth.
