You may or may not like some of the buttons or some of the functions on a Canon or prefer some on a Nikon. Fine - personal preference, I get it.
But quite objectively speaking having to do THREE DIFFERENT THINGS to change ISO on D750 is absolutely absurd. And those three things are in completely different places.
- You have to actuate the AF after a previous photo preview. Otherwise it zooms out of a picture instead of changing ISO, since it's not a dedicated button.
- You have to press the ISO button on the back of the camera with your left hand.
- You have to the wheel with your right hand.
Effectively the ISO read out on the top screen is useless, apart from providing information when carrying the camera around, since controls are on the back anyway. And if you want to modify bracketing it's in a completely different place altogether.
These are functions that all deal with exposure and lighting in the photo and they are all over the place even as you need to change them frequently - especially in travel photography.
On a Canon you press a button at the top and you adjust the ISO from the very same screen, just next to the button itself. The same with bracketing.
Again, having functions and their display put in different places is quite illogical and confusing (to say the least).
You may get used to it, fine. But it's hardly intuitive. I don't talk about other things since they are a matter of preference. I actually like the locking on the wheels adjusting the mode and even found the placement of ON/OFF switch rather good, since it allows operation with a single hand.
But having an ISO button shared with a fuckin' zoom in the gallery deserves capital punishment.
