Alright, I'm really trying to get myself one of these specifically for difficult receptions. I'm currently fully geared with m4/3 so I'm a bit lost as to what lens choices I can use for this sony full frame e mount. Can someone recommend two lenses, say a fast (1.6-2.0f) wide (somewhere between 16-30mm) and something in the 1.6-2.5f 80-100mm range? Cost is an issue so is there some non branded options I can use adapters for? Will this thing take old canon FD mount?

Ah questions!

Not many native "FE" (full-frame E-mount) lenses available at the moment. I went the route of Metabones MkIV EF adapter and Canon 24-105mm F4 IS. The A7s basically sees in the dark, so even at F4, it's been a good choice for me.

There is supposed to be a Sony FE 28-135 F4 Power Zoom lens coming out soonish which looks really great, so I was thinking to wait on any major investments until I could test that one out.
