>>4333215A modern camera with a readout speed of less than 1/200 is crippled. You can achieve that with a very fast sensor, or a fully mechanical shutter. Both are scanning slit mechanisms. Sigma includes neither.
I forgot to mention how hard sony cripples the -c models JUST so people won't buy them over the non-c models. The shitty EVF is not a design necessity. The half shutter is not a design necessity. If they uncrippled that shit, size and weight would go up by <20g and <0.5cm. They have slow sensors and absolutely require mech shutters.
>inb4 EFCS sync speed isnt that baaaaadHere's your bokeh bro.
But they have to protect a7iv and a7rv sales just like the a7iv is crippled down to shooting 6fps with 14 bit raws to protect a1 and a9ii-iii sales. It can't even outspeed the a7iii. It needs to be as bad as possible to be a stronger motivator to consoom.
