![]() ![]() If you change the shutter speed or the aperture, for instance, what you see on the EVF will change accordingly. However, one benefit to EVFs on mirrorless cameras is that they can give you a preview of what the final image will look like before you actually take the picture. A DSLR, by contrast, reflects the light directly to your eye. That’s because the mirrorless camera has to slow down the speed at which it captures images to grab more light, but still has to show you a moving preview. But in situations where the camera is struggling (such as in low light or with fast-moving subjects), the preview will suffer, becoming dull, grainy and jerky. When you're in good light, the preview on the screen or EVF of a mirrorless camera will look close to the final image. Some mirrorless cameras offer an electronic viewfinder (EVF) - a small, high-resolution screen in an eyepiece that simulates the optical viewfinder of a DSLR. ![]() With a mirrorless camera, you get a digital preview of the image on-screen. With a DSLR, the through-the-lens optical viewfinder shows you exactly what the camera will capture. If you are shooting video with a DSLR, be sure to find a model that has on-chip phase-detection sensors. Most low-cost DSLRs are slow to focus in this mode, though, as they don’t have the hybrid on-chip phase-detection sensors and have to use slower contrast detection to focus.īoth types offer speedy autofocus using ever more similar technologies. Newer Canon DSLRs (and the high-end Nikon D780) place phase-detection sensors right on the main image chip, along with the contrast-detection sensors, allowing them to function like a mirrorless camera with a live on-screen preview and fast autofocus.ĭSLRs can mimic a mirrorless camera by raising the mirror and showing a live preview of the image (usually called Live View mode). The Nikon D3500 has 11 large phase-detection sensors in its separate AF sensor and uses the entire image sensor for contrast detection. The Sony a6100, for instance, has 425 phase-detection autofocus points on its image sensor, along with 425 contrast-detection points. Nearly all mirrorless cameras (as well as the best camera phones) now have both phase- and contrast-detection sensors built into the image sensor. Those distinctions are essentially over now. Contrast detection is slower - especially in low light - than phase detection. Mirrorless cameras were restricted to a technology called contrast detection, which uses the image sensor to detect the highest contrast, which coincides with focus. mirrorless: Autofocus speedĭSLRs used to have the advantage here, because they use a technology called phase detection, which quickly measures the convergence of two beams of light. You can carry a mirrorless camera more easily and fit more gear, such as extra lenses, into a camera bag. It should be noted, though, that some of the newer mirrorless cameras - especially those that have full-frame sensors - are nearly as large and heavy as some DSLR cameras, so the savings in size and weight is negligible. That's compact enough to fit in a coat pocket or a small purse. The Sony a6100, for instance, has a body just 1.6 inches thick and weighs 1.3 pounds with its 16-50mm kit lens. They're definitely worth considering, especially if you're new to the market.Ī mirrorless camera body can be smaller than a DSLR, with simpler construction. Don't be concerned by the fact that they're not the latest model - things don't move that quickly in the camera world, and these cameras will still be generally very good in most areas. It's also worth noting that you'll often find the best deals on cameras a year or two old, as companies look to clear out stock for newer models. Cameras aimed at pros will be sold "body only," i.e., without a lens, so you'll have to factor that into your budget, too. For that reason, they're taking the win here.Ĭameras aimed at beginner and intermediate shooters will generally come with a "kit" lens - one that's pretty good for most purposes. Add in that the lenses for these cameras, especially second hand, are older and cheaper, and DSLRs can provide a hefty cost saving versus mirrorless systems. When it comes to camera pricing in general, DSLRs and mirrorless cameras are roughly analogous, with beginner models starting at around $500, and high-end professional rigs costing upwards of $2,000. However, now that DSLR technology is being unprioritized, the cost of those cameras is falling and you can now pick up an entry-level DSLR like the Canon Rebel T100 / EOS 4000D for just over $300 / £300.
