>>3300879The two most obvious advantages for the average joe are:
>Ability to have a smaller, and, more significantly, a lighter overall camera with short primes.>Exposure preview in the viewfinder.If those advantages aren't obvious to you, then you may never "get it."
Additionally, mirrorless cameras offer the following significant advantages:
>Ability to shoot silently and at a high frame rate in burst shooting. Wedding photographers appreciate silent shooting through a viewfinder, and press photographers will someday consider silent burst shooting to be the baseline standard.
>Ability to use a lot more data to expose and focus an imageBecause mirrorless cameras use the entire photographic sensor to accomplish what DSLRs do with a really low resolution secondary sensor located in the viewfinder, they are capable of exposing a scene more accurately and focusing far more precisely than DSLRs. Eye AF and covering the entire viewfinder, edge to edge, in AF points are, as yet, impossible with a DSLR.
>Fixes the "AF micro adjustment" flaw of DSLRsThe better DSLRs have a workaround -- the user can calibrate the AF characteristics of each lens they own and the camera will remember the setting -- but mirrorless cameras aren't susceptible to the problem to begin with.
>Fixes the mirror slap flaw of DSLRsThe Canon 5Dsr revealed that even when a DSLR has such a supremely large resolution sensor as 50 MP, you can still tell the difference between photos taken through the optical viewfinder and photos taken in live view (with the mirror locked up and an electronic first curtain shutter). The shock of the mirror swinging around inside the light box introduces motion blur inherently. It is also easier to implement mechanical shutters capable of >10 fps bursts when the mirror is taken out of the equation.
For all those benefits, if all I have to give up is battery life, then I'll gladly carry a spare battery or two in my pocket.
