At last a real 24MP professional DSLR from Nikon for under € 4k

Compared to the D610:
New sensor, TRUE (very important) to 12800 ISO sensitivity, better resolution display, better battery, finally professional level focus system and even easier.
Although more expensive, but I think it's worth it as the difference is quite noticeable, as in the hands, as well as later on the screen. Simply TOPP. The one can not miss and that is also in several online shops for a long time in stock, so I have no idea why Amazon now needs 1-2 months.
