Because the D810 has 36MP which at this point I am not interested in...So why not save the $$$ on the price of the body and put it towards glass,education, or lighting...I know the D810 is an awesome camera..But until I am a Full-Time Professional..I cant justify the cost..Thanks for your reply.
I also would be interested in those two features, it sounds especially useful for perched birds.
I'm wondering how much money over the D610 we would be prepared to pay for those features. My thoughts are that I'd pay half way towards the D810 price - otherwise why not just buy the D810. What do you think?

I will continue to grow with my D610 and wont grab the D750 right away..Need to make the $$ from my payed gigs before I go that route...It's up to you which one you get..For Birds I would skip the D610 and go for the D750 due to it being an action camera..(Birds flying etc)
Hope this helps..
