>>2899424> what does a mirror do and why are some marketed as without mirrors?a mirror is what is reflected through the viewfinder of dslr - so you see things through the lens of a camera (ie real time), a mirrorless camera will either have a digital screen and/or a viewfinder projecting a digital screen (eg watching a tv screen).
imo a consumer should buy the cheapest sony camera (a6000) as theyre most going to post on social media - where you can buy adapters for canon/nikon lenses in case you divulge into dslrs
