I've been thinking of switching to Nikon for a while now, Only for one reason. Dynamic range. I was going to sell my Canon 6D (which I love) and all my lens and give Nikon a shot. I was going to order the Nikon 610, but something inside stopped me from doing it. Instead I went to the store to take a look at the camera in person and test it out... The Nikon D610 felt terrible the second I picked it up. It probably has the worst grip on a PRO camera I ever felt. It was so uncomfortable even after a few minutes. The Nikon D810 was right next to it, so I was like let's see how this feels.... also terrible grip. It was surprised the Flagship felt so bad. I was thinking do all Nikons Feel like this? Finally I grabbed the Nikon D750 and wow what a difference. It really felt amazing in my hand, nice deep full grip. The Tilt LCD screen was also really really nice. I looked at the price and it was $800 more than the D610. No way I would pay $800 more for a better grip and tilt LCD ( I don't care about the better autofocus system on the D750). Still couldn't get over how bad the D610 and D810 felt in my hand. I figured while I was there I might as well take a test picture with my Canon 6D and the Nikon D610 for fun. The Canon 6D had better per pixel sharpness than the Nikon D610. Even though it has 4 megapixels less, the Canon image was sharper and more details were visible. Both shot raw, both loaded in CS6, all settings the same. Interesting. Of course you could sharpen the Nikon image to make it look like the canon when not viewed at full resolution, but that not the point. Perhaps the Canon is using a lighter anti-aliasing or low pass filter than the Nikon. I even checked dpreview's comparison tool and what do you know, it shows the same exact results that I saw. I wish I could take them outside and see if the dynamic range was better in real life, but obviously I couldn't do that. I'm sure the Nikon would be better, but by how much I don't know. I've seen the silly tests on-line when people underexpose a shot 5 stops and then bring out the shadows. That's ridiculous, not one underexposes images 5 stop in real life, so those tests mean nothing. Bottom line is before you switch to another camera I recommend that you test it out in store and see how it feels. As of right now I'm keeping my Canon 6D and getting a new lens for it. If I was going to even consider Nikon it would be a D750, it felt great. I wonder if the sensor is sharper than the D610. Has anyone switched from Canon to Nikon or Nikon to Canon? What was your experience like? Does anyone like the shallow and thin grip on the D610 or D810?
