Camera Test: Nikon D600 Full-Frame DSLR

A full-frame DSLR body has long been on the wish lists of many more photographers than could afford one. Now, both Nikon and Canon have announced cameras priced at about $2,100 (street, body only), pitching them as “low-cost” full-framers.

The first of these to come into our hands is the 24.3MP Nikon D600. While it does indeed feel less like the luxury experience of Nikon’s D800, it’s more like a Mini Cooper than a Hyundai Accent—high-performing with a bit of flair. In terms of its looks, many see a strong resemblance between the new camera and the Nikon D7000.

But when we ran the D600 through the Popular Photography Test Lab, we quickly discovered where the D600 surpasses the performance of the D7000 by a considerable margin.

In the Test Lab
The D600’s imaging proved well above economy class, with an Excellent rating in overall image quality in our tests from ISO 50 through ISO 3200. Its resolution was particularly impressive: 2930 lines per picture height at its lowest sensitivity of ISO 50.

Furthermore, resolution didn’t drop below our threshold of 2500 lines until its top ISO of 25,600 (Nikon calls this Hi 2). At ISO 12,800 (a.k.a. Hi 1), the D600 served up 2570 lines. At both of those settings, of course, noise was heavy enough to drop image quality ratings well below the floor for an Excellent rating.

In our color accuracy test, performed with DxO Analyzer 4.1, the D600 easily earned an Excellent rating with an average Delta E of 6.8.

Interestingly enough, the much pricier Canon EOS-1D X and Nikon D4 both peaked at 2530 lines at ISO 50 in our tests. These top-of-the-line DSLRs also sport fewer pixels, faster bursts, and are built to withstand circumstances that might prove devastating to cameras in the class of the D600. But it’s nice to know that you can get more resolving power from a camera that costs thousands less than those pro rigs.

And if you thought that the D600 might not be able to keep up with those two supercameras when it comes to controlling noise, think again. The D600 matches the 1D X and D4 in keeping noise to Low or better ratings all the way up to ISO 3200. All three cameras also reach Unacceptable noise levels at ISO 12,800 and above. And while the two pro bodies reach the stratospheric ISO 204,800, we think that the D600’s top ISO of 25,600 is enough for most shooters—amateur through pro.

The main area that the D600 fails to match more-expensive cameras is autofocus. The 39-point system in the D600 covers a decent amount of the frame, but is rated to work down to only EV –1. And indeed, the D600 gave up completely in our test when the light went below EV –1. Even there, we found more variability in AF speed than we’d like to see: While it averaged 1.27 seconds, in some instances AF time came close to 2 seconds.

At the brightest light level in our test (EV 12), the D600 focused in a less-than-speedy 0.48 second. By EV 6, that had slowed to 0.54 second, which, while not bad, is still behind the 0.49 second that Nikon’s own D7000 managed at that same light level.

Despite all the fuss we’re making here, in our opinion it’s better to sacrifice a little bit of AF speed to hit a lower price at retail than to skimp on the image quality. All in all, the D600 really impressed us in our lab tests.

In the Field
The new Nikon was also very pleasant to use in everyday shooting. The grip, while not as lovingly sculpted as the one on the D800 and D4, still feels nice in the hand and has a groove on the inside for your fingertips. Plus, there’s a ridge just below the shutter button that gives you leverage to tilt the camera.

Ample dedicated buttons give you access to most of the settings you’re likely to want to change while shooting. Photographers stepping up from entry-level DSLRs might not be used to some controls, such as the AF button built into the AF switch on the front left of the camera, or the autobracketing and flash buttons above that switch. But once you start using the camera regularly, you will likely find those controls well placed and quite useful.
