Sony Alpha a7S II Mirrorless Digital Camera with Microphone Kit

It most certainly does. The A7SII only records 4K at up to 100 Mbps and it is 420 8-Bit. The HDMI output is 422 8-Bit and a Ninja V records ProRes, which offers much less compressed files at higher Mbps amounts.

The Major different is the A7SM2 has about half of the sensor Megapixels of the 7M3. The 7M3 also had Phase/contrast auto focus and the 7SM2 only has contrast auto focus. The advantage of having about half of the Megapixels it allows the sensor to have a wider dynamic range for better low light performance.

It can do the job with 60 Mbps, but the best is 100Mbps.

Typically all lens adapters are glitchy and work better with some lenses than others. As far as the Metabones adapters, they auto focus better than others. Additionally, the Sigma MC11 works well also.

You cannot. This is a Sony E-Mount camera, it does not have an A-Mount. If you are looking for a lens with a great focal range for the full frame A7SII we suggest the Sony FE 24-240mm f/3.5-6.3 OSS Lens, B&H # SO2424035, instead. https://bhpho.to/2bMJL4c

Yes it can definitely shoot broadcast quality footage (or even better). It has a variety of resolutions and frame rates available to allow you match what is needed by your client. It has a micro-HDMI output. You can use micro-regular HDMI cables and go straight to your switcher, or HDMI-SDI adapters depending on what the rest of your setup is. I would recommend buying the AC power adapter piece if you are going to use it for a live production. The batteries don't last long, so being able to power it continuously is very helpful.
