Pentax wouldn't have to look very far to see what specs to include in the FF. D750 ads are splashed all over the Dpreview forums home page. The only sentence it has on the ad is:
Send Images directly to your smartphone with Nikon D-SLRs
Apparently, Nikon got the memo on smartphones and wifi. Also highlighted in the ad is the tilting LCD screen. Little doubt the Pentax is going to have a tilting screen with the 645Z already having it. A new day, a new tilting lcd screen.
A friend of mine, who has been committed to getting a D800 has now changed her mind to a D750. Looks like they have cannibailized their own lineup to some degree.
Anyhow, looks like there is plenty of room for Pentax and Sony to price their FF cameras under the D750. Go Pentax!!!
