>>3002686Personally I think the standard a7ii represents the best value, 12MP for me is too limiting, 42 is a bit unnecessary and heavy on the cpu & ram when it comes to editing.
If you're focusing on video, look at the s, if you're focusing on studio look at the r.
>>3002681Don't overthink that article, pic is a comparison of a sony and 28mm f2 and a nikon with 28mm f1.8 (closest I could find). Clearly there's a massive difference in size and weight.
The short flange distance not only allows these awesome, compact, high quality lenses, but also means you can adapt any old manual focus glass to it if you so desire.
As far as EVF's go, I'd never go back to an OVF, and I spent my first 4 years just shooting film! The advantages it offers in focusing, exposure, composition and low light are too big to pass up. Also, if you haven't tried one, get to a shop and give it a go, the quality is great. Do remember it will probably have a slow kit lens on it and you'll be inside, make sure to point it outside so you can see what it looks like when the sensor gets more than enough light and you get the full framerate.
>>3002691Once you figure out that there's no such thing as an "ideal" exposure, and you're relying on technology to tell you best, as opposed to having complete control from the start, you'll see OVF's are dead.
To give you a "real life" example, when on a DSLR I will set it to either aperture or shutter priority, then wiggle the exposure comp dial to where I think it may need to be if the light isn't even, then shoot, then pull my eye away to chimp to see if I made the right adjustment.
With mirrorless it's always in manual, because it's faster than AV, I set my aperture based on my artistic preference, then adjust shutter speed and iso until the exposure looks like I want, then click; it's exactly as I previewed it so no need to chimp. Oh and DSLR's can't focus accurately with lenses faster than f2.8, lol.
