D600 has very powerful Dynamic Range...impressed, sadly the LCD is quite low resolution & not a joy to use..also, zero exposure simulation. Does D750 have these things?
I haven't used the D750 in a long time. Here is a video I found that shows how to turn on exposure preview: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-mzOlI9SqPmE.html
