I'm not terribly interested in anything made by Sony these days.
Sony, like HP, used to make wonderful quality equipment, now they seem
to be run by soulless accountants with no understanding of how their
companies got to the top in the first place. They also seem to delight
in ignoring standards to try to lock users into buying *everything* from
them.
admit that I love that, thanks to the mirrorless design you can use
about any legacy lens on them (with the proper adapter). But after
reading a petapixel article on the a7s and its potentially being the
best astrophotography (low light) camera on the planet, I had to read
up on it.
There are various technical advantages of mirrorless:
1) shorter registration distance means no retrofocus, which means better
image quality at wider angle of view.
2) shorter registration distance means that you can use just about any
lens made.
3) No mirror bouncing around means no mirror bouncing around.
4) Live view works much better for low light manual focus etc. What you
see is what you get. With a mirrorless you don't get the huge shutter
lag while everything bounces around between live view and actually
taking the photo.
There are certain ergonomic advantages to the pure optical path when
looking through the viewfinder.

Can you imagine what the Pentax hoards would say if Pentax came out
with a full frame camera with fewer megapixels than the flagship? This
Sony camera is fewer megapixels than the PREVIOUS Pentax flagships:
the K-5, K-5ii/iis
I would love it if I could buy a K-3 in both 24 and 12 MP versions, with
the associated advantages to both resolutions.
If you could have one of these A7rs with an astrotracer feature that
worked with manual focus lenses, that would be seven shades of awesome.
