In-depth guides on camera sensors, pixels, and core hardware — from 200MP sensors and pixel binning to autofocus and image stabilization.
"Weather sealing" is one of the most heavily marketed — and most widely misunderstood — features on modern cameras. A sealed body can shrug off drizzle, dust, and sea spray, but it is not a…
For years, the image sensor inside your camera was designed first and foremost to take still photographs. Video was a feature that rode along on that hardware. That is no longer true. Today's most advanced…
For most of the twentieth century, the single-lens reflex (SLR) camera was the default tool of serious photography, and at its heart sat a surprisingly simple mechanism: a hinged mirror that bounced light from the…

Every photographer eventually notices them: faint dark spots that appear in the same place in every frame, most visible against clear skies and bright walls at small apertures. Those specks are not on your lens…
Every photographer has hit the same wall: a scene the camera simply cannot hold. The sky blows out to pure white, or the shadows collapse into a noisy mess — sometimes both at once. The…
When you buy an interchangeable-lens camera, you are not just buying a body — you are committing to a lens system, and the mount is its foundation. It determines how close the glass can sit…
When you shop for a camera or lens, two phrases keep coming up: crop factor and "35mm equivalent" focal length. They sound technical, but they are really just a translation tool — a way to…
Every photograph depends on one small but critical decision: how long the sensor is exposed to light. That job falls to the shutter. Modern interchangeable-lens cameras offer two ways to do it — a mechanical…
