Apologies in advance for the self-indulgent "which __ should I buy" type thread.
I hope others will find it useful, as I suspect I'm not the only one scratching my head from the Leica owner side.
Planning to buy A7s in next month or so.
* Currently a Leica M240 owner, long time Leica shooter, with Leica primes I like (35/50 lux asph), plus a ZM25/2.8.
* Purchase of A7s is predicated on the ultra-high ISO ability, and video.
Not normally a zoom shooter, but am considering the Sony zooms for the IS and focal range coverage as a second-camera to my M240+prime.
It seems odd to buy the Sony 35/55 lenses with my existing Leica 35/50s, it seems like they will out resolve the 12MP sensor anyhow.
Options - purchase any one of following, and use my existing Leica glass for rest of range
* 35 - AF, native, super light, very sharp
* 55 - AF, native, very very sharp
* 28-70zoom - AF, IS
* 24-70zoom - AF, IS, sharper than 28-70
* Or don't buy a lens, Just use my primes?
Instinct was maybe the 35, as the A7s+35 is 10% lighter than my M240 body alone, and 40% light than M240+35lux!
Puts A7s kit into one-hand-shooting weight class for me.
In-store it already felt a bit nose-heavy when I tried the 28-70.
And lastly, given Sony's rapid iteration cycle, I hesitate to buy the A7s a bit, wondering how many months until A7sII w/ IBIS and/or internal 4K..
Then again, Sony iterates their mass-market mainline (RX100/A7) faster than their more niche products (RX1 / RX10 / A7r / A7s).. maybe it's more than mere months away.
