Hi Aram,

For astro landscape photography, you will not want to depend on the lens'
hard stop at infinity with such a terrific EVF: just use the EVF and manual
focus to make the stars sharp.
With the M's you don't have a choice but to depend on the hard stop. On
other camera's with a good EVF or LCD (use a loupe) it's best to see your
focus on the stars.
Hope this helps chip away at spending all your $ on the SL.   I certainly
am considering it except that for my WA lenses don't play well with it. So
 in addition to the SL I would need a 35/1,4 ASPH and a 21/1,4 ASPH. Add
that to the autofocus 24-90 and basically I am SOL!
:-)
Best,
Bob
