A DSLR is a Digital Single-Lens Reflex camera.

“Reflex” refers to its mirror, which reflects lite from the lens to a ground-glass viewing screen.

SLRs and DSLRs have washed this since the 1930s so we can see and focus through our lens before we take our picture. This mirror snaps out of the mode when we accept the motion picture.


Today mirrorless cameras can show u.s. alive images from the sensor, making mirrors, ground glass, Fresnel lenses, prisms and DSLRs all obsolete. Mirrors were only needed in olden days when we had no way other than basis glass to see what came through our lens until nosotros developed our moving-picture show.

Mirrorless cameras utilise a rear LCD and usually an electronic viewfinder to show us the live electronic image direct from the image sensor earlier the picture is taken.

Today’s electronic finders are live; as of 2018 they no longer are visibly delayed and they aren’t jerky. Jerk your finger in front end of one, and information technology looks live in the finder.

Electronic Finder Advantages

What You See is What Y’all Go

DSLR finders merely show what nosotros’re seeing. They can’t prove playback and they certainly don’t give any thought equally to what y’all’re going to get. Electronic finders bear witness how our photos will await, not requiring the states to waste matter time playing them dorsum afterwards to see what we got.

Electronic finders are a huge advantage because mirrorless cameras show u.s. exactly how our camera will render the concluding paradigm (exposure, white residuum, distortion correction, highlights, shadows, colour residual and saturation, contrast, etc.) equally nosotros’re shooting, while DSLRs couldn’t evidence us any of that through their funky sometime optical finders.

The Canon EOS-R finder even shows the alive image corrected for lens distortion to ensure precise framing, while DSLRs can’t mayhap predict this and will show parts of the prototype that are cropped later on lens baloney correction.

If highlights are getting blown out or car white balance isn’t cutting it, we run into this earlier nosotros printing the shutter in mirrorless.

I ofttimes prepare my white balance creatively, similar to SHADE in the sunset shot below to turn what was a deadening greyness sunset into brilliant orangish, and my EOS-R showed me exactly this as I shot, consummate with what item I was getting in the silhouettes, with no need to play dorsum. I could fix my photographic camera until I got exactly what I want, which is a silhouetted daughter, with detail in the vivid dusk and in the darker shadow in the moisture sand in the foreground:

Canon EOS-R Sample Image

Daughter in Dusk, Lahaina, Maui, September 2018.
Canon EOS-R, Catechism RF 24-105mm f/4L IS at 91mm, ane/500 at f/10 at Auto ISO 100, SHADE WB, Standard Film Fashion, +four saturation, exactly as shot as NORMAL JPG. bigger or photographic camera-original © file.

I set my colors to insane, and I can see exactly what I’m getting equally I’m composing. I never have to stop and play back to 2d-judge. I can see exactly how highlight, shadow, mid-tones and everything look every bit I’chiliad making my shots. If my reds are blowing-out because I have the saturation set to +xi, I’ll see it as I’m shooting.

Hitting the PLAY button to see what you’re getting after y’all’ve shot is and so film era. Finally mirrorless lets united states see, correct and optimize what nosotros’re doing
while nosotros’re doing information technology.
Having to stop and look at your developed pic or a digital playback means you’re living in the past (pun intended) and missing what’s going on around y’all and missing great shots. With mirrorless you lot’re always live and getting the shots the one-time-timers are missing while looking at their LCDs for yesterday’south news.

Zoom Playback and Focus

A huge reason I love mirrorless is that I tin can see all my menus and playback in the finder, especially without needing glasses or a finder loupe to see a tiny rear LCD in direct sunlight, and that I can magnify the finder during shooting or playback to see explicit details under any condition.

I fifty-fifty can set my Canon EOS-R to magnify my active AF area automatically if I turn the manual focus ring!

High Speed Prototype Stability

Mirrorless finder images never black-out, jump or mistiness equally you shoot at high frame rates. Simply the iPhone and Sony A9 are this good today, but all mirrorless will catch up before long.

All DSLRs black-out equally every moving picture is taken, and at loftier speeds a DSLR finder prototype starts to smear vertically from the mirror flapping upwards and down at 10 frames per second or more.

Authentic and Useful Depth of Field Previews

DSLRs have crummy depth-of-field previews. To most people, all these buttons exercise is make the finder dark, so people never employ the depth-of-field preview. Even for people who practise, the finders get and then dark equally the lens stops down to its taking aperture that you can’t encounter much.

Mirrorless finders don’t darken with depth-of-field preview. They stay just as bright and then we tin see what we’re really going to get. We can select the best aperture for how we really want our pictures to wait
we printing the shutter.

Mirrorsless cameras bear witness exactly how the picture show will look at very large apertures like f/1.4, while DSLR viewfinders have never shown how shallow the depth-of-field actually will exist at apertures larger than virtually f/ii.5.

Few people know that modernistic DSLR “bright” screens can’t evidence the full amount of a lens’ defocus at apertures wider than near f/2.v. If you employ your preview button on a DSLR, yous can’t come across the actual depth of field at apertures wider than f/two.five on modern laser-cut matte screens (nosotros haven’t used actual ground drinking glass since the 1970s), but today with my mirrorless, my f/1.2 and f/1.0 lenses show
how little is in focus in my finder.

If you think I’grand kidding, accept your f/1.8 or faster lens and effort your preview push button on your DSLR, and you won’t run across any change until you stop down to f/ii.8 or smaller.

Yes, on a DSLR, all lenses faster than f/ii.5 don’t look whatsoever brighter or have any less depth of field in the finder than an f/2.five lens does, while on the EOS-R for the first time we can come across exactly how picayune is in focus with a fast lens.

Daylight Legible

While DSLR finders are vivid in daylight, there’s no proficient way to see a rear LCD in direct sunlight.

Mirrorless finders are bright and colorful under direct sunlight considering you’re looking in a shaded peephole, and you also tin can set menus and see playback in vivid detail in whatever light.

Night-Time Legible

While DSLR finders get night in the dark, and are dark in daytime with slower zooms, mirrorless finders are e’er brilliant and total-color, fifty-fifty in the dark.

Yous might non know that homo vision becomes monochrome in very dim light (we don’t run across colors outdoors under moonlight), while our moving-picture show and digital pictures do show full color when exposed well.

Mirrorless finders show the aforementioned colors our pictures will show, while DSLR finders bear witness the gray image our eyes see at night.

Heck, at present that I have a Canon EOS-R, fifty-fifty indoors in daytime my 5DSR finder looks dim and muddy by comparison.

Finder Size

While electronic finders and DSLR finders look nigh as large (OK, my Canon EOS-R has a slightly bigger prototype than my Canon 5DSR’s finder), any electronic finder looks huge compared to squinting at a tiny 3″ LCD for playback on a DSLR.

Information Orientation

While we take it for granted that the data in a DSLR finder is tilted 90º when we shoot vertically, amend mirrorless cameras similar the Canon EOS-R magically rotate all the displays so we can read them when nosotros hold the camera vertically.

Level Displays

DSLRs have crummy level displays in the finders, while mirrorless usually accept very practiced colour-coded level displays.

Night Stealth

Subjects tin can see the ground-drinking glass of a DSLR through the lens. When a DSLR’southward AF zone lights in reddish, frequently the subject will run into some red calorie-free coming through the lens if it’due south pointed at them at dark.

No light comes out of a mirrorless lens from the sensor.

Of course either kind of camera has lighted indications in its finder which can light your confront and make yo u visible to a subject in the dark if you lot don’t use a blind properly.

Protects your Eyesight

When y’all signal a camera at the sun, peculiarly with long, fast lenses, you’re not going to be blinded from an electronic finder — but you lot might with a DSLR’s optical finder.


Full-Frame AF

There is no full-frame DSLR that lets us autofocus on the top, sides, bottom and corners for regular shooting.

Mirrorless cameras autofocus anywhere in the frame, a huge advantage, while DSLRs but autofocus near the center.

AF Speed

Mirrorless focuses as fast as DSLRs do. There is more than variation between camera and lens models from each brand than there is betwixt the two technologies.

AF Accuracy

Mirrorless cameras are much more than authentic.

DSLRs have their AF sensors in the bottom of the photographic camera, and look through the lens via a series of smaller sub-mirrors behind the principal mirror. While in that location are AF Area indicators on the screen, the actual sensors are coupled via a few mirrors. Any tiny positional errors in whatsoever of the mirrors or AF sensor or image sensor all add upward to errors between where the lens is focused and the epitome sensor.

Mirrorless camera AF sensors are office of the epitome sensor, so in that location is no fault. That’due south why mirrorless cameras frequently accept no AF FINE Melody adjustments, and even of they do, rarely if ever need any adjusting.

Especially with fast f/1.2 and f/1 lenses, mirrorless cameras consistently get perfect focus of which I only dreamt with my SLRs and DSLRs. I know, I’ve been calibrating the mirrors in my 35mm SLRs since the 1980s to keep focus on film aligned with what I see in my finder.

Of grade there’south always the potential for error if the subject field is moving or someone selected the wrong AF sensor, but if you use your camera correctly, there is no more autofocus error. Hallelujah!

AF Tracking

While mirrorless and DSLRs runway similarly depending on how avant-garde is your photographic camera, electronic finders practice a far better job of showing you lot what the AF system is doing while it’s doing it.

Size & Weight

Mirrorless bodies are smaller than DSLRs because they don’t need mirrors and prisms, but the lenses are the aforementioned size and weight.

Once you add the same lenses you used to use with a DSLR, mirrorless systems go well-nigh the same size and weight.

In fact, new mirrorless lenses tend to be bigger and heavier than DSLR lenses because they’re designed for even higher resolution to match futurity cameras.

Mirrorless doesn’t have whatever size advantage when y’all consider the whole system. Mirrorless only gets pocket-sized if y’all use but one or 2 small-scale lenses, but not if you first bringing all your serious glass.

If you lot want small, Sony’due south A6000 with the tiny PZ 16-50mm lens is what I bought my own mom, and it’s very inexpensive for a country-of-the-art camera with instant autofocus.

Battery Life

Mirrorless cameras usually utilise more battery power because they need to be on and processing images continuously anytime you lot’re looking through them, while DSLRs mostly utilise power only as you take each flick.

However if you’re taking long sequences of pictures at high frame rates, mirrorless cameras have more battery life considering they aren’t having to flip a reflex mirror continuously, which becomes a ability-wasting fan.

Battery life is better in DSLR if yous look through the finder more than you actually shoot, while mirrorless gives more shots per charge if you’re shooting a lot of long sequences in continuous fashion.

While DSLRs get betwixt 800~three,000 shots per charge in bodily use, I go betwixt 300~7,500 shots per accuse with mirrorless.

Silent Shooting

Mirrorless wins. Most better mirrorless cameras take silent modes. As of 2018 the all-time camera for this is the Sony A7 Three, while virtually other have more restrictions on what features work or non in silent manner.

DSLRs can’t shoot silently this except sometimes in their kludgey alive-view (mirrorless) modes.

Cool Cistron

Looking at your LCD while other people can run into you means you yet aren’t ready to shoot, or that you don’t know what you lot’re doing, or that yous lack the skill and confidence to accept gotten the right shot in the first place.

It’s OK to go everything set earlier y’all arrive on set, simply if you lack the talent and experience to go the shot right and have to look at your screen to dial it in, I’m not hiring y’all to acquire while on my job. I’ll rent a pro next time.

This is another fashion mirrorless rules: you can do all this while looking through the finder, looking like y’all’re shooting while in fact you’re yet trying to set up upwardly your camera.

I propose y’all tape an ACROS 100 or Velvia box-end over the LCD so people think you lot’re shooting film! The only time I use an LCD on a mirrorless camera is to show someone else what I shot, or if I’yard working at a weird angle. Considering my Canon EOS-R LCD flips 180º and but shows black plastic if y’all similar, you can tape a box end over the back side and only flip information technology dorsum to the LCD if I need it. Use a 120 or 220 box-finish to confuse the hipsters.


At high frame rates, a DSLR mirror is flipping and so wildly that the finder image is blurred vertically, and the finder is blacked-out a significant portion of time.

The best mirrorless cameras, like Sony’s A7 III, A7 R III and A9 are so advanced that their finders don’t black-out, don’t blur and in the A9 don’t fifty-fifty go jerky.

While the fastest sports photographic camera today is the mirrorless Sony A9 which cheerfully runs at 20 FPS completely silently and does information technology with full tracking autofocus and exposure for each frame, some mirrorless cameras just run at their highest speeds with locked focus and exposure.

DSLRs have reached their peak in pro models like the Canon 1DX Mk II, while all mirrorless cameras are notwithstanding getting better all the time. Heck, even the iPhone X cheerfully runs silently at 10 FPS and has the tools to let u.s.a. select easily among all its shots.

Exposure Accuracy

Mirrorless cameras have meliorate exposure accurateness because they always read the epitome straight from the image sensor, while DSLRs have to use a separate meter in the prism which has to guess earlier the picture is taken.

While virtually better DSLRs use color multi-segment meters, mirrorless cameras have far more zones and are seeing in the same color settings as the bodily pic, and remove more potential for errors.

I go consistently perfect exposures in actual use from my mirrorless cameras, while all of my DSLRs regularly exposure bounty in sure circumstances.
