DSLRs have significantly gained popularity not only among professional photographers but also photography enthusiasts and hobbyists. Offering a much larger sensor as compared to point and shoot cameras as well as semi SLRs , DSLRs offer considerably higher picture quality and offer flexibility in choosing lenses as per the requirement due to its interchangeable lens body. Recently, there’s another category of camera that also offers similar picture quality with its large sensor and also interchangeable lenses which you’ll not typically find in a point and shoot camera. There had been a lack of certainty for a while with what to call this category of camera, but the name mirrorless seems to have finally stuck and surprisingly it points to something which this camera doesn’t have. “A Mirror”
In order to understand what exactly this mirror does, we need to find out the basic structure of DSLR as shown in the given diagram.
Now that you know what a DSLR is, the term ‘mirrorless’ should make some sense. A mirrorless camera does not have a mirror in front of the sensor. That means there’s no need for a prism up above; there’s no need for a mirror chamber inside and hence the overall body size of mirrorless cameras reduces significantly. Typically mirrorless cameras have the live view screen at the back to track the frame live but some cameras have been introduced lately which offer electronic live view (Will be explained later in this article). The below table will give you detailed insight on difference between DSLRs & Mirrorless cameras based on certain factors.

Since there is no clear answer to the question “Which camera is right for you?”; there are too many factors that should be considered in order to make a final decision based on personal preferences. If you are looking for an ‘easy to carry’ camera for your travel and you are serious about photography, then mirrorless cameras are for you; but if you don’t bother carrying extra pounds along with you and love the traditional way of shooting, DSLRs are your perfect partner. But as we said earlier there is no clear winner and all depends on your preferences.
