The perfect compact zoom for the A7S...

[Fonk]

So last night I went to a reading at a coffeeshop, and wanted to take pictures of the speakers and crowd.  I knew it was going to be pretty dimly lit, so took my A7S for its high-ISO capability.  I knew I was going to be alternating a lot between wider and longer shots, and didn't want to be swapping primes all night, so opted for a zoom.  I don't have any native FE zoom lenses yet, so that left me choosing between adapting my (A-mount) Minolta 28-70mm f/2.8 G lens, or else going crop with my E-mount 16-50mm f/3.5-5.6 PZ kit lens.  I wanted to be as inconspicuous as possible, since I was going to be taking some close-up images of the crowd, too, so opted for the 16-50 PZ, even though this meant I'd only get about 5MP.  The images are just going up on the web for some reportage anyway, so the size limit is no big deal.  For what I needed to do, I loved that combo!  I don't know if it's physically possible or not, but it'd be awesome if we could get a zoom lens with that same size profile for FF.  Either that, or get a crop body with the same ISO capability as the A7S, though that might be the taller order.  Anyway, I find this sort of low-profile lens and high-ISO-capable camera to be the perfect marriage for this type of shooting, so would love to see such a combo made possible (w/o the cropping down to 5MP)...  I was "only" shooting at about ISO 20,000, so I suppose it might be possible with the A7RII, as the ISO is pretty good on that thing, and the crop factor would still yield about 18MP.  Of course, that's another $3200...
