Just thought I'd pop in and say "hi" as I've got got myself a D750 and a Tamron 24-70 2.8 to go with it (you can bet the D750 replacement will happen very soon now - happened with my D7000 lol). I've been using a D7000 and Tamron 17-50 2.8 (pretty much lives on it) so it's certainly a big jump in weight! So far liking the feel of the D750 and the deeper grip - even though I keep hitting the wrong buttons on the back.
Not had the chance to properly go and test things out yet but managed a snap in the garden with my only model who doesn't walk away or complain.
