About to pull the trigger on a Nikon Full frame camera. Just acquired the 14-24 2.8 and now I own the "Nikon Holy Trinity" and have been told that it might be a good idea to upgrade the camera to match the lenses. Looking at the 610, 750 or 810. Leaning toward the 810. Thoughts anyone? Currently own the D90 for the last 6 years.
Without hesitation I would recommend the D810. I have a pair of D800s and I shoot everything - landscapes, sporting events like HS Soccer and LaCrosse, Equine competitions, portraiture, macro, auto racing, motorcycle racing, birds in flight, street photography, Pro Table Tennis competitions, product and other commercial photography, architectural and real estate, etc. There is nothing I can't use the camera for that would make me want to use something else.
There are a lot of people that believe that you just can't do a good job using this camera for action sports and other subjects. Well, I am from the old school, where we did what we could initially with single frame advance 35mm cameras, then later with motor drives that could do 4 fps. About the same as my D800. We, including myself, managed somehow to capture excellent action shots with that primitive gear. I don't buy the hype. The D810 is 5 fps, which is more than enough. And the image quality is unmatched by just about any FX format camera, including the Canon 5DS R - though admittedly it's pretty close. The Nikon still holds a slight advantage in shot noise, dynamic range, camera noise and overexposure tolerance.
The D610 is mostly menu driven, making it slow to use, and the D750 has a few advantages - like the articulated LCD preview screen, slightly more advanced AF system, built in WiFi, 6.5 fps in full frame mode, lighter smaller package and $1000 lower price. However, the D810 has a 33% longer expected shutter life, a flash sync speed of up to 1/250 sec, a better viewfinder (better coatings for less reflections and clearer view), and where the rubber meets the road - better dynamic range, more megapixels, 1 stop improvement in low light sensitivity (for low light focusing), a viewfinder shutter to keep out extraneous light while making long exposures, no low-pass filter on the sensor, and a body that has an operational feel like the other entry level professional bodies that preceded it. This is not a night and day difference. In fact, the differences are actually pretty subtle in most cases, and you are not likely to see the difference when comparing images. But the reasons for buying a D750 instead of a D810 are often overblown, and vice versa.
That being said, the better camera is the D810. Though the D750 is no slouch. The D610 is in a different and lower, league.
