What is the difference between mirrorless camera and a DSLR?

[roberthans]

I've been recently researching about which DSLR is recommended for a beginner to use. D3300 were the top list on Google. However, the speed of the camera might not that good as others. I just went to the electronic shop on yesterday and they recommended me mirrorless camera instead of DSLR!

It looks quite good and cool for the mirrorless camera. It is lighter than DSLR of course, it would be very convenient to use if you are traveling around. However, I'm looking for a camera which is under my budget of $550 AUD and able to really capture a good image of landscape and night view.
Any recommendation for that?


I didn't find the right solution from the internet.
