These vary from camera to camera, but can include things like the ability to show advanced exposure aids, such as a histogram or waveform monitor, right in the viewfinder. An EVF can also show you exactly what your image will look like — from exposure to depth of field to white balance — before you take the shot, helping you dial in your settings quickly and easily compared to the guess-and-check method of an optical viewfinder.
Video requires constant exposure of the sensor, so a DSLR has to be in live view mode for video to work at all. This is one reason why mirrorless cameras are better for video than DSLRs.
While most mirrorless cameras no longer have a slow and clunky autofocus, some DSLRs still offer faster performance in low light. Mirrorless cameras balance it out with more features, however, like eye detection and intelligent subject tracking. Sony leads the field here with its Real-Time Eye AF , but pretty much every mirrorless manufacturer offers some kind of eye-detection.
While mirrorless cameras could surpass DSLRs in AF performance in the future, the one area where they are likely to always fall short is with battery life. Improvements in efficiency have helped, but the all-day battery life of DSLRs remains a big advantage for certain photographers, particularly those covering sports or other live events. Mirrorless cameras are not inherently better or worse than DSLRs, although they have advantages in some areas like video and disadvantages in others such as battery life.
Mirrorless cameras, particularly the more compact models, tend to be a great choice for casual photographers, who may not be bothered by the shorter battery life and who want a camera they can easily take with them. Electronic versus optical viewfinders Early electronic viewfinders were considered far inferior to their optical counterparts, but this has changed dramatically in recent years.

Learn more about mirrorless. DSLR Definition what is a dslr camera? Mirrorless vs DSLR. And before we go deeper into the pros and cons, here's a quick diagram of both camera systems. The basic differences. With less moving parts, they're quieter than DSLRs.
Without the mirror, this camera also beats DSLR in size. The electronic viewfinder can be used in video mode, while the viewfinder on a DSLR cannot. Camera manufacturers have learned to produce more sensitive chips and to better suppress noise from small sensors. Furthermore, several mirrorless camera makers now use larger image sensors.
There are also a number of full-frame mirrorless cameras that have the same size sensor 35mm that's found in premium DSLR cameras. Sony's A7 line pioneered this, but now Canon and Nikon also have full-frame mirrorless models. Winner: Draw With equivalent sensors and image processors, both camera types can take great photos. Autofocus is the key differentiator for video. Typically, mirrorless cameras have had the advantage, since they were more likely to have on-chip phase-detection focus sensors.
Most DSLRs still can't use phase detection with the mirror up while recording video, so they have to use the slower, less accurate, contrast-detection focus method. This leads more often to the familiar blurry look in the middle of a video, when the camera starts hunting for the right focus.
Nikon has just started introducing on-sensor phase detection in its higher end of cameras. Both camera types have also been making the move to 4K, or Ultra HD, video with four times the resolution of HD footage. Sony, for instance, now has 4K in its base mirrorless model, the a, and Canon has equipped its beginner-oriented Rebel T8i with 4K capture.
Winner: Mirrorless With superior autofocus in more models, mirrorless cameras provide the best results for most filmmakers. Both camera technologies can shoot at very fast shutter speeds and capture a burst of images quickly. With the exception of high-end DSLRs, mirrorless cameras have an edge, though: the lack of a mirror makes it easier to take image after image. They also have the option of using an electronic shutter just setting how long the sensor reads the light , which means they can shoot more quickly and silently.
Winner: Mirrorless The simpler mechanics of mirrorless cameras allow them to shoot more photos per second. Generally, DSLRs offer longer battery life, as they can shoot without having to provide live view on an LCD screen or an electronic viewfinder, both of which consume a lot of power. That said, mirrorless camera battery life is improving.
For instance, the Sony a , which debuted in , is rated for shots per charge when using the LCD preview. Its successor, the a, is rated for shots from the same battery. But they still can't touch DSLRs. The entry-level Nikon D, for instance, is rated for a whopping 1, shots per charge. If you opt for a mirrorless camera, you might want to consider also buying a second battery. Choosing a DSLR gives you access to a plethora of lenses from a number of manufacturers, ranging from cheap and satisfactory to professional and wildly expensive.
Mirrorless models are more restricted, offering access to a small number of lenses from the camera maker, though the selection is growing. As they have been around longer, DSLRs tend to have a better selection of other accessories, such as speedlights flashes. The difference is especially stark among traditional camera makers. However, right now, Canon has only eight M-series lenses available for its lineup of mirrorless cameras; Nikon has 16 lenses for its Z series of mirrorless models.
Some may not support autofocus, for instance. The mirrorless lens selection is better for companies that focus on the technology. Sony, for instance, now has about 50 E-mount lenses for its mirrorless models. Panasonic and Olympus, which share the Micro Four Thirds sensor format, each make about 40 lenses that can be used on cameras from either maker, and Fujifilm has about 30 lenses for its X-system of mirrorless cameras. In addition, you can generally purchase adapters to use DSLR-size lenses on a mirrorless camera that's made by the same manufacturer such as for Canon or Sony.
But that often comes at a price of altering the focal length and zoom characteristics and sometimes disabling or slowing functions such as autofocus. Winner: DSLR DSLRs still offer access to a wider range of lenses, but the gap between the two types is narrowing quickly as more mirrorless lenses become available.
If you regularly venture off the beaten path, it's worth looking at a model that adds an extra level of protection. Entry-level cameras of either type, such as the Nikon D, often come with plastic bodies that are strong enough for casual use but may not hold up well if they get tossed around, say, for extended backcountry trips.
The next step up in durability is an alloy body that can better withstand bumps and scrapes. The Sony a, for instance, has a magnesium-alloy body. Full weather sealing will keep out corrosive dust and even rain. But there are some exceptions, like the plastic-body Nikon D
