>>3438078>DSLR can do that as well, but can also use the mirror and viewfinder.Ehhh. You can, but only on the rear LCD, not the viewfinder, which is a much different shooting experience (i.e., it sucks). Live view is very much treated as a second class citizen on DSLRs, and for good reason.
> Canon for example has a pretty short flange distance as well.Canon has a short F-F distance by DSLR standards, but it's still long as shit by mirrorless standards. You'll never mount a rangefinder lens on a Canon, or an Olympus OM, or Minolta. You can only adapt Pentax on crop because the mirror is too big on full frame.
Plus, the most advanced adapter you can get to mount on a Canon is one with a little widget to poke the Nikon aperture control. You'll never get a speed booster to use full frame lenses' full image circle on a crop sensor, and you'll never get an adapter that gives you electronic aperture control.
And even then, Canon can only really adapt Olympus OM, Nikon F, M42, and Leica R of the common lenses out there. They can't do Minolta (either manual SR or autofocus A), they can't do Canon FD/FL, and they can only kind of do Pentax K (you can adapt it onto crop Canons but not full frame).
Oh, and with those old mounts, on mirrorless, you can manually focus with features like zoom in the viewfinder and/or focus peaking to let you manually focus accurately without swapping out your focusing screen.
>From my perspective a DSLR with short flange distance can do everything a mirrorless can do and has the advantages of having the mirror viewfinder.It sounds like you're not really interested in the advantages of mirrorless, you just want to argue that they're not advantages.
Yes, using a DSLR in live view mode gives you some of the advantages of mirrorless, but it brings in a shitload of the disadvantages. You really have to experience shooting something like a Fuji to truly understand what a different experience it is. It's pretty cool.
