Question: Who highly recommends the Nikon D600? So many people do NOT recommend it. I want to upgrade my D5000 to a more professional camera.
Document: I purchased this camera as an upgrade from my D5000. It has more then exceeded my expectations. I work with a professional photographer on a part-time basis. I shoot different events (weddings, Bar/Bat Mitzvahs..etc.) and can personally say this camera has allowed me to expand my role as a second shooter. I have also done portraits on my own and have had amazing results. I did a lot of research on several different Nikon cameras and kept on coming back to this one.
I love love love this camera! I use this camera as my primary for my photography business and couldn't be happier. As a owner of 6 Nikon Cameras (no problems with any of them just like to upgrade!) I would highly recommend any Nikon but this one is super great!
I'm not going to go into all the technical specifications here because that has and will be covered by many others. I just wanted to add that other than this camera having the 3rd highest rated sensor ever.... nearly matching Nikon's $6000 flagship, it is also a well built camera. Regardless of what some people say, the D600 does NOT feel like a D7000 in the hands. I own the D600 as well as a D7000, D3100, AND a D300S.
I bought this camera when came out. I went from D7000 to D600, since I wanted to move up to full frame camera. I have say that it is day and night. Full frame capture much more pictures in every shot and 24 MP is much needed upgrade from 16 MP. Although I loved D7000 and still recommend it to anyone who want to start in the DSLR, but if you want to step up, I recommend D600.
There are many modes to choose from, from indoor, landscape, portrait, night shot, etc, etc. Granted leaving much of the settings to the camera to decide won't necessarily yield the best shot but I find that it still far surpasses any point and shoot camera I have ever owned and far surpasses the D5000. Even when my friends/family see the shots I've taken on auto mode, they are still blown away with the quality images. They actually think I'm a professional photographer!
No negatives come to mind. Is this the perfect camera? I'm sure that depends. As for me, I love it for the image quality, feature-set, low-light capability, and access to so many lens choices. I make use of the crop mode liberally when reach is needed. This feature is accessed by one button push away. What a hoot! Highly recommend.
The D600 is the first consumer affordable full frame DSLR. It lives up to its promised specs and delivers sharp images. You will need to fiddle with the settings to get the type of image you want. Buts that's the fun of a new camera. The user interface, is similar to many other Nikons. Menus are deep, and extensive, but not as extensive as the higher level professional cameras.
I would highly recommend it to anyone who's looking to get into full frame cameras at a decent price point or anyone who just wants to have darn good pictures taken. In my case, the photos and moments I've been able to capture with this camera are priceless. For that reason alone, this Nikon D600 is worth every penny to me.Hope this review helps!--- February 21, 2013 UPDATE ---I've been using this camera for some time already, a little over three months.
The snaps at ISO 2000 were great, and even testing at ISO 6400 showed nice results. I was concerned that I might get one of those with oil and dust on the sensor/mirror that many have mentioned, but mine is fine. Amazon was amazing, as always, shipping the camera to me in two days. It is expensive, but highly recommended if you want to move up to superb pictures.
Until the Nikon D600 came out. It was the right price point for something I had the budget to get into. Being that this is my first venture with full frame cameras, please excuse my review if it's not as technical or complete as other professional photographers and my only real basis of comparison with the D600 is with my old D5000.
Answer: I am very happy with my D600.   So many people do not recommend it simply because there are SO many people out there who are serious about their cameras and photography in terms of sheer numbers and the folks with negative thoughts are the generally the ones who post opinions.  Two thoughts, if I had had the money, I probably would have gone for the D800 despite the added size and weight, and if you have a collection of DX lenses, you may want to upgrade to a camera you can use them on rather than the D600 which really needs full format FX lenses.  Remember that good lenses are generally more important than the actual camera body for great photography.  Finally, both the D600 and D800 are very complex cameras.   You will grow very old before you have even begun to have used all of the features!  :-)
