Stuck on making a decision between mirrorless and DSLR? Let’s talk about it. The biggest difference between the two is the viewfinder, or how light reaches the sensor and your eye. DSLRs use an optical viewfinder (OVF), while mirrorless cameras use an electronic one (EVF).
DSLR
A DSLR (Digital Single Lens Reflex) is based on a technology that has been around for many years. It uses a mirror and an optical viewfinder to let you see what the lens is seeing. Here’s what happens:
-
Lens: Light enters through the lens
-
Mirror: A mirror reflects the light upwards
-
Prism: A petaprism or pentamirror redirects the light toward the viewfinder
-
Viewfinder: The viewfinder shows you the image that the lens is seeing using the reflected light
-
Shutter button: When you click the shutter button, the mirror flips upward, the shutter exposes the sensor, and the sensor captures the light which is what makes that clicking sound when the photo is taken.
Mirrorless
What is a mirrorless camera? The name says it all - it has no mirror inside. Unlike a DSLR, which needs a mirror to reflect the light upwards to redirect it towards the viewfinder, the light goes straight through the lens to the image sensor.
Instead of an optical viewfinder, you see the frame on an electronic viewfinder (EVF). Because there is no mirror, mirrorless cameras are smaller and lighter, and the sensor is able to handle focusing, exposure preview and video all at once.
Another perk of a mirrorless camera is the silent electronic shutter. Most mirrorless cameras can shoot completely silently, which is perfect for weddings, wildlife, concerts, newborn sessions, and anywhere a shutter click would be a distraction.
OVF vs EVF
The viewfinder is what you’ll be looking through every time you take a photo, so it is worth thinking about which type you prefer.
Why photographers love an EVF:
What you see is what you get: Adjusted exposure, white balance, or a film simulation and see the result through the viewfinder before you press the shutter.
Exposure tools at your eye: Live histograms, zebras, and focus peaking appear right in the viewfinder, so you can catch mistakes before pressing the shutter button.
A better view in low light: An EVF can brighten a dark scene so you can still compose and focus.
Instant review: Check your shot in the viewfinder, which is a lifesaver while you’re shooting in the bright sun and the rear screen is too hard to see.
Easier manual focus: Magnification and focus peaking make manual and vintage lenses much easier to use.
Why some photographers stick with OVF:
Even with how far EVFs have come, many photographers still prefer an OVF. Many shooters feel that OVF simply feels more natural and keeps them more connected to what’s in front of them. It’s a big reason DSLRs still have a loyal following.
A true, real-time view: No lag, refresh rate, or pixelation. This is a big reason sports shooters held onto DSLRs for so long.
See what’s about to enter the frame: You can see past the frame lines and anticipate a subject walking into your shot. Street photographers love this.
Easier flash shooting in the dark: An EVF previews the scene without the flash, so it can look nearly black. An OVF lets you see and frame normally.
Better in high contrast: Your eye handles bright highlights and deep shadows at once better than an EVF, which can clip one or the other.
Fewer distractions: No menus, playback, or color shifts, just a window onto the scene. It’s easier to stay in the moment.
A break from screens: For people who stare at a monitor all day, shooting without one is part of the appeal.
So, Which One Is Better?
Mirrorless cameras are more popular nowadays. They’re smaller, lighter, and faster. Without the mirror, the lens mount sits closer to the sensor, because of which lenses can be smaller, simpler, and less expensive. In a DSLR, the sensor is covered by the mirror and shutter, so the only time it’s active is the moment of exposure, when the mirror flips out of the way.
This is why DSLRs tend to have a longer battery life. In a mirrorless camera, you see the image directly through the image sensor, so the sensor is always on. Because of this, video autofocus is often better, since the camera focuses with the same sensor it records with. A DSLR relies on a separate autofocus module when you’re shooting through the viewfinder, so focusing in a live view or video module is often slower.
DSLRs still have advantages. Some photographers still prefer an optical viewfinder and the battery life is better because the sensor isn’t constantly running. DSLRs are also proven technology so most repair shops know them well. But they tend to be heavier and bulkier.
