Bests & Worsts Reviews from Amazon

Update; I have not had one issue - no spots and would buy this again. Coming up on three years. Thanks Nikon! I have had the D610 since Oct 22, 2013 and I am very impressed with everything about this camera. This is my first FX format camera and I love it. A friend of mine has the the D600 and he has never had an issue with oil on the sensor so I was never worried about it with the D610. I purchased through Amazon and the packing was awesome, just make sure someone is home to sign for it : ) . I own the Sigma 35mm F1.4 DG, Nikon 50mm f/1.8D, the Nikon 85mm f/1.8G, and the Tamron AF 70-200mm f/2.8. Nikon SB-600 flash works with it fine. It does have a DX crop mode that you can use on a non DX lens, might help with the the long end of a zoom for sports to make a 200mm equal to a 300mm. Nice big viewfinder image helps me with focus issues I had on the D90. I loved the D90 but the D610 is on a different level. I use this for high school and college sports, orchestra and band. The quiet shutter mode has helped with the indoor events. After using it this weekend, I have noticed that there is a big improvement with low light focus on the Tamron AF 70-200mm f/2.8/D610 over the D90. It did not "hunt" like with the D90, I think because it could find contrast easier. I tried shooting in the shadows, even though it found contrast in very low light it was not always in focus but did not hunt all over - and it was a usable shot instead of no shot. It correctly did not auto select DX with the Tamron. With the D610 the "70" end of the 70-200 is now much more usable. Essentially with the D90 I was carrying a 105-300 lens. Now I don't need to bring a second lens if I can stand 5 or 6 feet back to get waist to head coverage shots. I did not notice color or corner issues in the shots I got, I was expecting to see problems. Shooting an indoor swim meet I noticed the corners where very sharp with no perception of light fall off. There was no focus hunting at all, and I took over 100 shots. Because of the higher resolution of the D610, I was able to crop to get a lot closer to the subject. For sports this combo is awesome, use the 3D mode for auto focus. The Sigma 35mm F1.4 DG is amazing. I will probably use this lens most of the time. The only lens I will need to take along with is the Nikon 85mm f/1.8G . Between the two lens and switching to "DX" mode, I will have essentially 35, 50(dx crop), 85 and 127(dx crop) in primes with me. I hope this helps someone switching from DX to FX. If you own a D600, and have an issue with spots on your images, search the internet for "Technical Service Advisory for Nikon D600". Nikon is replacing all of the defective shutters.
