A Sony with a Zongywahtever 50/0.95, sample pictures of people in artificial light (which have to cause problems with electronic shutters) some mentioning of dimmed LEDs (there's already problems with cheap transformers on them, not to mention the dimmer).
But great to getting to know some exotic "issues", especially if the camera sells like warm bread...
Okay - not soooo exotic: LEDs come more and more, each artificial light source can have a difficult frequency* and causing problems. There are a lot of things to consider using the electronic shutter (it's not a first curtain electronic thing but fully electronic...). No free lunch, nowhere. And on top of that, it sucks battery even more than the Fuji (which so far were second champion, best battery suckers are still the Sigma Merrills with their tiny batteries) - and makes one looking like a normal smartphone shooter just with a very chunky piece of gear
No, not entirely: using this nearly cool tilt display, one can play sort of Hasselblad feeling by looking into it from the top. Onto a reflecting surface. And focusing in SloMo. No one needs to worry much if the D850 is the perfect "everything goes camera" - it's not, but it's still pretty neat.
* One day I wanted to be very clever and used an LED light pack to lighten the AF target. To get it very bright over a long time, I didn't use the batteries (that would have been real DC) but instead used a transformer (which still brings in a bit of AC). I didn't see it in the OVF, but LiveView was pulsating. So I thought, maybe the AF module will also get confused by this frequency?
There's limits and no-go-situations for electronic shutter, but not disturbing birds is none of them.
And Zonghyi whatever things come at the price of manual focus which I find very limiting - so no thing for me and in the other lenses I haven't seen a different bokeh. Maybe because I rarely do these kind of comparison shots. If I use LV, it's mostly for a reason.
But what sucks with this camera: the pictures look worse on an old iMac 27". Moiré is also working the other way - not into the camera, but onto the screen. Time for a 5k iMac, I think?
