Anyone upgrade from a D700 to D750 - how was the transition? What's the usable ISO with the D750, I would happily use 6400 with my D700..
I have.
Only had the 750 for a couple of weeks, and still have the 700, which is going no-where. It's a back-up for now.
The main difference is the ergonomics.
I use back button focus, and although the rear AEL button can be programmed as a rear af button, the placement is different.
Not bad, just different.
Obviously the buttons are different on the top too, but nothing which cannot be learned with a bit of practice! It's just learning a new muscle memory for certain adjustments.
The focussing is amazing though. This thing will focus in the dark I think !
As for the ISO, the difference is night and day ! Much cleaner files, even much higher than 6400, up to 12, 800 is still clean.
Having said that, I rarely (yet) have had the need to push it.
I'm still getting used to it though, so the transition is still ongoing. I had to add a grip, as the 750 felt too small for me personally.
Overall, a cracking piece of kit, which I'm looking forward to using more over the next few weeks.
If you get a chance, play with one for a while, and you'll feel the handling differences yourself.
As for the actual workings, (ISO, focusing, IQ etc, you will definitely be impressed!)
Hope this helps.
