I agree with the OP. Perhaps I am missing something, but the only advantage I see to mirrorless is the ability to make a smaller, lighter camera. Yet, whenever people bring up size and weight, even those who want mirrorless say that those factors are not the main reason.
Here's my running list of the better future mirrorless could offer that have nothing to do with size:
1) You can shoot through the viewfinder without mirror slap without need to resort to MLU or LiveView.
2) Focus peaking in the EVF is a super handy tool for shooting with manual focus lenses at large apertures.
3) The EVF can show you more than basic LCD indicators -- drop in a realtime histo (if so inclined) or whatever other heads-up information you'd like to see. Some folks prefer a spartan VF, while others want the fighter cockpit blasting information all over the screen. Unlike an OVF, you can dial that in to your preference.
4) Removing the mirror box allows the flange to sensor distance to be dramatically reduced. Though we think of that principally in mirrorless rigs getting
thinner front to back, that's not all that does for us. Reducing that flange distance allows you to use adaptors to use other manufacturer's lenses. That is massive if you have lots of glass from older systems and don't need razor fast AF.
5) An EVF can have its brightness turned up in dark environments. They can't see in the dark, but they
can bail you out in environments that OVFs on SLRs can struggle with (nighttime shooting, dark events like concerts, etc.).
6) There are less mechanical things to wear out or fail in a mirrorless rig than an SLR, so mirrorless should be more mechanically reliable than an SLR. (This is somewhat contentious, because there are some 'mechanical-stuff-is-more-reliable' rebuttals the SLR camp could make. So, yes, a mirror box's effectiveness can wear down, but a more 'driven by wire' mirrorless system could (I suppose) could have more
electronic avenues to fail.
You can't short out an OVF, right?)
7) I'm not well read on this, but I thought I read that going mirrorless has a lower (or no?) AFMA hassle level -- so dialing in lenses in mirrorless is less of a burden.
8 ) Mirrorless can pull off some comically fast shutter speeds if you have the need & have the light. I believe Fuji (and maybe some others?) have a rig that shoots 1/32,000s, which SLRs simply cannot muster.
This is not an exhaustive list, but these are the more mentioned upsides I've read about.
Keep in mind that I prefer SLRs and will continue to do so until mirrorless technology eliminates the critical 'pain points' for how I shoot -- lag, responsiveness, burst rate with AF/AE, etc. I have a 5D3 and my next primary rig will undoubtedly be another SLR, but perhaps
after that I'd consider giving FF mirrorless my money.
