Entry level + full-frame = Nikon D600. Let's see what it's got.

24.3 megapixel FX full-frame CMOS sensor

5.5 frames per second continuous shooting

ISO 100-6400 (expandable to 25,600)

3.2" TFT LCD

Dual SD card slots

Full-frame? What does that mean, you ask? Simply put, a full-frame sensor is the same size as a 35 mm (36×24 mm) film negative. A larger sensor means larger images with greater resolution, even when blown up to large print sizes.

Before we go any further, we'd like to give a big thanks to Chipworks for helping us with the teardown, and for providing the awesome sensor images you'll see below.

Before we take a look inside the D600, let's take a look at its port side, aptly located on the port side of the camera.

Hi-speed USB

HDMI output: Type C mini-pin HDMI connector

GP-1 GPS unit input

Starboard, ho! Unlike the D800 and the D4, which feature CompactFlash and XQD card slots, respectively, the D600 sports dual SD card slots.

Oooh là là! The exposure mode selection dial atop the D600 has a lock button in its center. Say 'so long' to accidental dial turns!

If you're used to wielding a Nikon D7000, holding a D600 may start to feel like déjà vu. Let's compare the two and see how similar they really are.

Even without the different exterior markings, distinguishing the D600 from the D7000 is pretty easy once the body cap is removed, exposing the comparatively gigantic viewfinder mirror.

A shot of the camera controls reveals very similar button counts, button locations, and button functions.

The D600 seems to have a slight size advantage, but how slight is "slight?"

Check out this shot of what appears to be the D7000 by itself. Look closer, though, and you will notice that the D600 hides quite nicely behind the similarly sized D7000. Apparently "slight" really is slight!

Do not get the two cameras confused, though. They may look simlar on the outside, but the full-frame sensor in the D600 will certainly raise the bar as far as photo quality goes.

"Safety first!" That's our motto!

Before we pull this bad boy apart, we remove the battery and battery cover from the device.

Nikon claims that the 7.0V-1900mAh-14Wh Lithium-ion battery can take 900 shots per charge, an understandable downgrade from the 1,050 of the D7000, most likely due to the improved internals.

It seems that Nikon likes to wait a while to design new batteries. When the D90 debuted in 2008, it used the same battery as its predecessor, the D80. Likewise, the D600 uses the same battery as the D7000.

Our teardown experts are getting antsy; they want to open this puppy up!

There are multiple hidden screws throughout the body of the D600.

Off come the viewfinder eye cup and battery grip cover, and we're ready to get inside.

Several Phillips screws hold the bottom cover in place.

Poof! Like magic, the screws are released and we gain our first glimpse of the D600's insides.

The only goodie on the underside of the bottom case is the battery release mechanism. If—for whatever reason—yours fails, it can be replaced pretty easily.

As we continue to remove parts, we get to the standard tripod mount, held in securely by four Phillips #00 screws.

It's nice to see that this mount comes out separately from the rest of the body. It would be a shame to compromise a $2,100 camera just because the tripod mount becomes cross-threaded.

The front case is the next piece to surrender its spot on the D600's body.

The depth-of-field preview and function buttons both lay inside the front case underneath two rubber covers.

Though not a common repair, replacing these buttons is certainly feasible.

The battery grip pops off next. That's another component easily dispatched.

From our past experience with DSLR cameras, we know it's not going to be this easy for long.

The rear cover is secured by a few sneakily-hidden screws.

How hidden are these screws? We found them underneath the eye cup, rubber grip, and viewfinder diopter dial.

The rear cover (along with the LCD assembly) finally gives in and jumps ship from the rest of the body.

Well, this is nifty. Notice the red dots drawn on the inside of the rear cover? Each dot seems to correspond to the location of a screw. We assume this is done to keep track of each screw during the manufacturing process.

Every button on the rear cover is tied to a single ribbon cable. This makes repair a bit more costly if a single switch gets fried.

We were disappointed to find that the LCD is fused to the rear case, and cannot be replaced without replacing the entire panel.

If you scratch or crack the display glass on an older Nikon DSLR like the D90, it's possible to find an inexpensive replacement and fix it yourself. With the inseparable glass, though, D600 users will definitely want to opt for some type of screen protection.

Bit by bit, we pull off the last few pieces of the outer case, revealing—no surprises here—more shields and circuit boards surrounding the ports and SD card slots.

Fast forward a bit, and you can see that this device is totally full of shields and grounding straps—that's not even all of them!

By now we are rather adept at finding the hidden screws on this device. We locate and remove the two small screws securing the top case assembly in place.

Anyone else keeping track? By our count, removing all of the outer case components requires unscrewing a total of 36 screws. And we're just getting started…

It's time for an iFixit fun fact! See the red square in the first picture? That circle with a line through it denotes the location of the image plane, which is the vertical plane that the image sensor lies in. You'll find the same symbol on most cameras, and it's the point where camera lens minimum focusing distance measurements are taken from.

17 steps in and we've got our hands on some green! The first board out is the top case button board.

I see, you see, we all see an IC!

Nikon NHHS-2 219MM

Under the board lay a few more goodies, the first of which is the upper LCD assembly.

Not surprisingly, the D600 sports the same wide viewing angle upper TFT-LCD as the D7000.

We find the LCD controller, ROHM segment driver BU9794AKV.

We could probably write an entire teardown for the top case of the D600 alone, but we decided to spare you. Take our word for it, there's a lot of stuff crammed in there.

At this point we'd like to stop and let you appreciate the space management that goes into designing a DSLR camera. Wires and ribbon cables run amuck, yet everything works together in perfect harmony, allowing you to express your artistic vision with the press of a button.

With the number of screws left in the upper case roughly over 9000, we decide to divert our attention to the rest of the device.

EMI shields are very helpful. They work wonders in preventing external electromagnetic induction and radiation from messing with the circuitry of electronics.

That being said, they're usually a huge pain in the spudger to remove.

Luckily, this large EMI shield is removed by simply unscrewing some Phillips screws, and does not require any desoldering.

The large square of thermal compound also tips us off that this shield works double duty as a heat sink, removing any excess heat from the D600's motherboard.

Moar screws! Our Phillips #00 bit is getting tired, but it keeps unscrewing screw after screw!

With a few more screws removed we can finally pull out the board that holds the 24 megapixel full-frame sensor.

To get a closer look at the full-frame CMOS sensor, we remove the frame and layers of filters covering it.

With the filters off, we get a full-frontal view of the full-frame image sensor. The 35.9mm x 24.0mm sensor is a major size upgrade from the 23.6mm x 15.6mm sensor in the D7000, and accounts for a 50% increase in total effective pixels (24 million/16 million).

Ever wondered what a corner view of the image sensor magnified 350x with a Scanning Electron Microscope looks like? Wonder no more. Can't get enough magnification? Here is a view magnified at 3500x.

These tilted images show the micro-lenses making up each pixel of the full frame sensor.

The second image shows that these pixels are well-spaced, demonstrating why not all pixels are created equal. The large size and ample gaps between pixels allows room for metal signal lines to move each pixel's data without blocking light to the individual photocathode sensors.

Interesting enough, the image sensor in the D600 is manufactured by Sony.

Thank you Chipworks for the amazing pictures! If you want to read more on the Sony sensor, check out their full post on the subject.

And now.... desoldering time!

With the help of our soldering station, we free the secondary power board from the D600.

It's not at all uncommon for the various daughterboards inside a camera to be soldered together. Connections need to be sturdy and not take up a lot of space, and surface mount soldering fits the criteria very well.

If there's such a thing as a connector-to-circuit-board-area ratio, the D600's primary power board has an impressive one.

A spudger makes quick work of the non-soldered connections, and the primary power board is free.

This is the point in the teardown when stuff just starts coming out of the device left and right. A lens mount here, a ribbon cable there, whatever that is over there... the only thing that could make this better is if it was made into an awesome montage and set to "You're the Best," à la Karate Kid.

The IC on the large ribbon cable is a ROHM BU9798KV multifunction LCD segment driver. Moving on...

We were relieved to find an insulated rubber cover on the beefy 350 µF flash capacitor, protecting us against what could have been a dangerous shock.

Just in case it wasn't so welcoming, we were ready with our capacitor discharge tool—always a good idea when you're dealing with large electrolytic capacitors.

Nikon D600 Repairability Score: 2 out of 10 (10 is easiest to repair)

The battery can be easily replaced by opening the compartment with your thumbnail.

The tripod mount comes off after removing four Phillips #00 screws.

The D600 has several wires that need to be desoldered in order to take it apart.

Many, many screws hold the device together.

The LCD is fused to the rear case, and cannot be swapped without replacing the entire back of the camera.

For absolute safety, you need to discharge the flash capacitor, otherwise you risk accidentally killing your camera (or yourself).
