DSLR VS. MIRRORLESS CAMERAS ???

DSLR, MIRRORLESS CAMERAS???? WHICH IS BETTER? AND WHAT ARE THE DIFFERENCES? 

SO MUCH HAS BEEN TALKED ABOUT LATELEY ABOUT MIRRORLESS CAMERAS, AND EVERYONE IS COMING OUT WITH NEW CAMERAS THAT ARE MIRRORLESS CAMERAS.  ARE THEY BETTER CAMERAS?  SHOULD I GET RID OF MY DSLR FOR A NEW MIRRORLESS CAMERA, OR SHOULD I JUST ADD A MIRRORLESS CAMERA TO MY COLLECTION?  IS THERE AN ADVANTAGE OF HAVING A MIRRORLESS CAMERA TO MY PHOTOGRAPHY EQUIPMENT?  LET'S EXPLORE ALL THESE QUESTIONS TODAY:
AS  YOU CAN SEE IN THE DIAGRAM HERE, THE MAIN DIFFERENCE IS THAT YOU DON'T LOOK THROUGH A VIEWFINDER WITH A MIRRORLESS CAMERA.  A DSLR CAMERA USUALLY WILL GIVE YOU THE OPPORTUNITY TO LOOK THROUGH A VIEWFINDER THROUGH A MIRROR THAT BOUNCES UP WHEN YOU TAKE THE PICTURE, AND THEN WHILE THE MIRROR IS UP, THE IMAGE IS RECORDED ON THE IMAGE SENSOR.  WITH A MIRRORLESS CAMERA, THAT DOES NOT TAKE PLACE.  WHEN YOU PUSH THE BUTTON, THE IMAGE SENSOR JUST RECORDS THE IMAGE ON THE SENSOR WITHOUT ANY MIRROR MOVEMENTS AT ALL. 

AS  YOU CAN SEE THE TOP PICTURE, THE FIRST MAIN ADVANTAGE IS THAT MOST MIRRORLESS CAMERAS ARE SMALLER.  NOW YOU CAN HAVE HIGH QUALITY CAMERAS THAT CAN CREATE THE SAME GREAT IMAGES, WITHOUT THE BULKINESS OF A DSLR. 

I FOUND A GREAT ARTICLE FROM PICTURE/CORRECT FROM A PROFESSIONAL THAT EXPLAINS IN DETAIL ALL ABOUT THE DIFFERENCES.  HIS NAME: Rajib Mukherjee
++++++  plus:  a great article from  Tom's Guide on the same information.  Read this all, and I think you will know which is the way you should go.


Time and again there have been debates about the effectiveness of mirrorless camera systems over DSLRs (or is it the other way around?). With arguments placed on both sides, the matter is beyond a concrete resolution in the foreseeable future. It’s similar to the Nikon versus Canon debate that’s been raging forever. Here, Techquickie brings in another perspective on the question of which is a better—DSLRs or mirrorless cameras:

For a complete explanation of how it all works, click this link here:


SIZE:
The first and most obvious point of difference between a mirrorless and a DSLR camera is the size.

In a DSLR, a mirror bounces light coming through the lens and redirects it toward the pentaprism / pentamirror. In turn, that prism projects the light, which you can see through the viewfinder. This mirror flips up and down when making images. Thus, DSLRs require a larger space to accommodate a mirror, as well as allow it to flip up and down.

Mirrorless systems don’t have a mirror–hence the name–so they’re slimmer and less bulky.

 DSLR CAMERA

VIEWFINDER:
So, how does a mirrorless system’s viewfinder work? Mirrorless cameras have no optical viewfinder. The viewfinder projects the image that the sensor sees or records. There are some obvious advantages to that. Let’s say your image is over or underexposed. When you look through an optical viewfinder you won’t get to see the actual image you’re going to capture. In other words you see the image that the lens sees and not what the sensor sees. On an electronic viewfinder you see the actual image you’re going to capture. That means you have an early warning system to avoid an over or under-exposed image.

MIRRORLESS CAMERA

There are, however, some disadvantages to an electronic viewfinder. One of the primary disadvantages of an electronic viewfinder is the lag. Electronic viewfinders have improved considerably over the years; the lag is no longer as pronounced as before. But it is still there, no doubt. Another problem is pixelation. Thus, a lot of old school photographers will still prefer to see the ‘real’ thing rather than an electronic representation.

LENSES:

DSLR cameras have a long history. The optical marvels that were made a decade or even two decades ago still work on the newer digital SLR cameras. Plus, there is an already established line of lenses dedicated to DSLRs.

Mirrorless systems don’t have that legacy. Having said that, this is just a temporary matter. As mirrorless systems gain in popularity new lenses will hit the market.

SHOOTING SPEED:

There are some obvious advantages to using mirrorless systems, and one of them is a high continuous shooting speed. The lack of a flipping mirror inside the camera means it can make images at a much faster rate, which is advantageous to sports photographers, just to name one example.

AUTO FOCUS:

Auto-focusing is one area where mirrorless systems lagged behind their DSLR cousins. However, that difference is shrinking quickly. There are now several mirrorless systems that boast a comparable auto-focusing speed to DSLR systems.

BUDGET:

If your budget is on the lower end, opting for a DSLR gives you more value for your money. A lower end mirrorless camera often lacks a number of key features. A DSLR, on the other hand, even at the lower end of the spectrum, tends to offer a more complete, feature-rich package.

This is just an overview of the current state of things. Imaging technology is improving at an incredibly fast rate. Soon newer technology and more improved versions of both these systems will hit the market, blurring the line of demarcation even more.


DSLR vs. Mirrorless Cameras: Which Is Better for You?

When you get serious about photography, you face a choice: Do you buy a digital single-lens reflex (DSLR) camera or a mirrorless camera? You can get great photos with either, but each has its pros and cons.

DSLRs use the same design as the 35mm film cameras of days gone by. A mirror inside the camera body reflects the light coming in through the lens up to a prism (or additional mirrors) and into the viewfinder for you to preview your shot. When you press the shutter button, the mirror flips up, a shutter opens and the light falls onto the image sensor, which captures the final image. We'll go through the features and capabilities with our top DSLR pick, the $392 Nikon D3300.

In a mirrorless camera, light passes through the lens and right onto the image sensor, which captures a preview of the image to display on the rear screen. Some models also offer a second screen inside an electronic viewfinder (EVF) that you can put your eye to. Our example of a mirrorless camera, one of our favorites, is Sony's $598 Alpha a5100.
Here's how the two technologies compare.

Size & Weight

DSLR camera bodies are comparatively larger, as they need to fit in both a mirror and a prism. The body of the Nikon D3300, for example, is a rather bulky 3 inches deep before you put the lens on the front. With the 18-55mm kit lens, the camera weighs about 1.1 pounds.

A mirrorless camera body can be smaller than a DSLR, with simpler construction. The Sony a5100 has a body just 1.6 inches thick and weighs just over a pound with its 16-50mm kit lens.
Winner: Mirrorless Camera
You can carry a mirrorless camera more easily and fit more gear, such as extra lenses, into a camera bag.

Autofocus Speed

DSLRs used to have the advantage here, because they use a technology called phase detection, which quickly measures the convergence of two beams of light. Mirrorless cameras were restricted to a technology called contrast detection, which uses the image sensor to detect the highest contrast, which coincides with focus. Contrast detection is slower — especially in low light — than phase detection.

This is no longer the case, though, as mirrorless cameras now have both phase and contrast detection sensors built into the image sensor, and can use both to refine their autofocus. The Sony a5100, for instance, has 179 phase-detection and 39 contrast-detection points on its image sensor, while the Nikon D3300 has 39 phase-detection sensors in its separate AF sensor, and uses the entire image sensor for contrast detection.
Winner: Draw
Both types offer speedy autofocus, with mirrorless cameras offering hybrid sensors that use both phase and contrast detection on the sensor.

Previewing Images

With a DSLR, the optical viewfinder shows you exactly what the camera will capture. With a mirrorless camera, you get a preview of the image on-screen. Some mirrorless cameras offer an electronic viewfinder (EVF) that simulates the optical viewfinder.
When you're shooting outside in good light, the preview on the screen or EVF of a mirrorless camera will look close to the final image. 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. 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. A DSLR, by contrast, reflects the light into your eye, which is better than the camera sensor at low light.
DSLRs can mimic a mirrorless camera by raising the mirror and showing a live preview of the image (usually called Live View mode). 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.
So, if you are shooting mostly in good light, both types will perform well. If you are often shooting in low light or other challenging conditions, though, a DSLR will be easier to shoot with.
Winner: DSLR
For many situations, especially low-light shooting, the DSLR's optical viewfinder is better.

Image Stabilization

Shaky hands make for blurry pictures, and the effects are magnified the longer your shutter speed, or the more you zoom in. Both DSLR and mirrorless cameras offer image-stabilization systems: Sensors measure camera movement, and the camera slightly shifts either part of the lens or the image sensor in a direction that's opposite to the shake. Some mirrorless models shift both the lens element and the sensor in a synchronized pattern.
MORE: Best DSLRs
We have found the differences between these approaches are minimal. The main advantage of sensor stabilization is that it works with all lenses. Lens stabilization only works with lenses that have it built in, which are often more expensive. Either way, most modern cameras can deal with a small amount of camera shake to produce a sharper picture, but can't compensate for larger movements.
However, there are a few exceptions. Mirrorless cameras such as the Olympus OM-D EM-1 Mark ii and the Sony A7R Mark II offers 5-axis image stabilization, which is a feature not found on DSLR yet. This has prompted a number of pro videographers to switch over high-end mirrorless cameras due to their smoother, less shaky footage. But as prices for these cameras start at $2000, they are often outside the range of most buyers.
Winner: DrawImage stabilization technology is largely equivalent in both camera types.

Image Quality

Both types of camera can take high-quality pictures, with similar resolutions and amounts of graininess, known as noise. Mirrorless cameras' smaller image sensors used to mean lower quality (as they couldn't capture as much light), but that is no longer the case. Camera manufacturers have learned to produce more sensitive chips and to better suppress noise. Furthermore, several mirrorless camera makers, such as Samsung and Sony, now use the same APS-C sensors found in the majority of DSLRs. Sony's A7 line of cameras use the even larger full-frame sensor type found in the best professional DSLRs.
Winner: DrawWith equivalent sensors and image processors, both camera types can take great photos.

Video Quality

Because of their on-chip focus sensors, higher-end mirrorless cameras are generally better suited to video shooting. DSLRs 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 to the familiar blur-blur look in the middle of a video when the camera starts hunting for the right focus. However, some newer SLRs are adding phase detection on the sensor, such as the Canon 70D and the Rebel T6i.
Increasingly, mirrorless cameras, such as the Sony A6300 and the $1,500 Samsung NX1, can capture 4K, or Ultra HD, video with four times the resolution of HD footage. The technology is slowly trickling down to lower-priced mirrorless models. Currently, only higher-end DSLRs, such as the Nikon D5, shoot 4K/Ultra HD video. Video professionals, if they use a still-photo camera at all, tend to prefer DSLRs, because the cameras have access to a huge range of high-end lenses. Autofocus isn't a concern for pros because they can often focus in advance, knowing where their subjects will stand in a scripted scene. 
Winner: Mirrorless
With superior autofocus in most models, mirrorless cameras provide the best results for most filmmakers.

Shooting Speed

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. The Sony a5100 can shoot 6 frames per second (fps), for example, while the Nikon D3300 can do only 5 fps. Although they don’t have mirrors, most mirrorless cameras still use a mechanical shutter, where a physical shutter lifts to expose the image, as it produces better results. They also have the option of using an electronic shutter (just setting how long the sensor reads the light), which means they can shoot quicker and silently.
Winner: MirrorlessThe simpler mechanics of mirrorless cameras allow them to shoot more photos per second, at higher shutter speeds.

Image & Video Playback

Both camera types can display images on their screens (typically measuring about 3 inches) or via an HDMI output to a television. Many now include Wi-Fi for sending images to smartphones for online posting, a feature that is present on the Sony A5100.
Winner: Draw
Both types offer large screens and video outputs, and some offer Wi-Fi connections to smart phones for quick image-sharing.

Battery Life

Generally, DSLRs offer longer battery life, as they can shoot without using the LCD screen or an electronic viewfinder, both of which consume a lot of power. However, both types will have similar battery lives if you use the LCD screens to preview and view captured images a lot, as this consumes a lot of power. However, all DSLRs and mirrorless cameras come with removable batteries, so you can carry a spare.

Winner: DSLR
DSLRs offer the ability to shoot without using the LCD screen or EVF, which can extend the battery life.

Lenses & Accessories

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.
The proprietary mirrorless systems from manufacturers like Sony (A series), Pentax (Q cameras) and Samsung (NX series) have the fewest lenses, because these companies have only recently introduced mirrorless models. Sony offers 17 E-mount lenses, for instance, while Nikon has hundreds available for its DSLRs. Mirrorless cameras such as the Olympus PEN series using the Micro Four Thirds sensor format have the widest selection of mirrorless cameras because they have been around the longest and are available from several companies. Olympus and Panasonic make the cameras and lenses. But Sigma, Tamron and other companies also make Micro Four Thirds lenses.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 offer access to the wider range of lenses, but the gap between the two types is narrowing as more mirrorless lenses become available.

Durability

If you regularly venture off the beaten path, it's worth looking at a model that adds an extra level of protection. Both DSLRs and mirrorless models offer this, such as the Pentax K50 DSLR and the Olympus OM-D EM-1 mirrorless camera. Both have alloy bodies and are described as weatherproof, meaning that they can shrug off rain and other splashes. The Nikon 1 AW1 mirrorless model takes it a bit further, though: It’s waterproof to an impressive depth of 49 feet.
Winner: Draw
Both types offer models that are hardened against the elements.

Bottom Line

Mirrorless cameras have the advantage of usually being lighter, more compact, faster and better for video; but that comes at the cost of access to fewer lenses and accessories. DSLRs have the advantage in lens selection and an optical viewfinder that works better in low light, but they are more complex and bulkier.
A mirrorless camera is better for a casual to semi-serious photographer who wants a lighter kit to carry around all day. A serious or pro shooter who wants access to a wider range of lenses and other gear would be better off with a DSLR.
