Nikon D7100 Review

Pinterest LinkedIn Tumblr

The Nikon D7100 has now been superseded by the newer D7200, but it’s still on sale and it’s anywhere from 15-30% cheaper, depending on where you shop. For the price of a Nikon D7200 body, you can get a D7100 and 18-105mm kit lens.

Superficially, the D7100 and D7200 look almost identical, so are the improvements in the D7200 worth the extra money, or are the D7100 turning into a real bargain? We’ve updated our original review to take a look at how good a buy the D7100 is in today’s market.

The good news about the D7100 is that it has a 24-megapixel sensor with no anti-aliasing filter – this is the very latest type made by Nikon and it’s almost the same as the sensor in the D7200. The D7200 is listed as having 24.2 megapixels, compared to the 24.1 megapixels in the D7100, but the image size is the same in both cameras at 6,000 x 4,000 pixels – the excess pixels in the D7200 is not part of the image area and suggest nothing more than a slight redesign.

Most camera manufacturers use an anti-aliasing filter (AKA low-pass filter) to reduce the risk of interference patterns known as moiré patterning that can occur when an object with a fine texture that’s close to the sensor’s resolving limit is photographed. You’ve probably seen this at some point on the television when someone has worn the wrong tie or shirt and a frenzy of lines is created at an angle to the fabric’s pattern.

Nikon claims that the pixel density of the Nikon D7100’s APS-C format sensor is sufficiently high that there are relatively few occasions when moiré patterning is likely to occur, and consequently no anti-aliasing filter is required. The downside of using a low-pass filter is that it softens the images slightly, and this has to be addressed by sharpening the picture post-capture.

Feature

The Nikon D7100 uses Nikon’s older Expeed 3 processing engine – this is the part of the camera which handles image processing, and apart from the general operational speed, it can influence the high-iSO image quality and continuous shooting performance. In combination with the sensor, the D7100’s processor enables a native sensitivity range of ISO 100-6400, which can be expanded to the equivalent ISO 25,600 if required.

The Nikon D7200, by contrast, has a newer and more powerful Expeed 4 processor. This gives it an ISO selection of 100-25,600, and this can be expanded right up to ISO 102,400 – though images at these higher settings are mono only.

Nikon says the Expeed 4 processor is 30% faster than the Expeed 3 processor in the D7100, though this doesn’t have a direct impact on the continuous shooting velocity. The D7100 and D7200 can both shoot at 6 frames per second, though the D7200 does have a much larger image buffer, a criticism of the D7100. This means it could capture more photos in a burst before it has to stop and finish processing them.

The D7100 and D7200 both have another trick up their sleeves that enables things to be pushed a little bit further – a 1.3x crop mode. This is useful if you need to get a little tighter in on your subject and don’t want to crop the picture post-capture, and it enables the maximum continuous shooting rate to be boosted to 7fps. This could be particularly useful for wildlife or aviation photographers, who typically need the longest focal length zoom available – the 1.3x crop mode will effectively turn a 200mm lens, for example, into a 260mm lens.

What makes the D7100 and D7200 good for sports and wildlife photography is the inclusion of Nikon’s 51-point Multi-Cam 3500DX AF module, which has 15 cross-type AF points around the centre of the frame. That is Nikon’s best AF system, and the one found in its professional DSLRs. The D7200 does, however, have the newer and slightly more sensitive Multi-CAM 3500II DX module. This one is delicate right down to a light level of -3EV (the D7100’s module goes down to -2EV).

Those who think 51 AF points is a bit excessive can opt to restrict the selection to 11 in single AF mode. As we have seen before with Nikon’s high-end DSLRs, in continuous AF mode the camera can be set to track the subject using 51, 21 or nine AF points after you’ve selected the starting AF point.

Alternatively, there’s 3D tracking available in continuous AF mode, which looks at the colour of the topic and attempts to follow it around the frame. However, if you want to keep things simple, the camera can select the AF stage for you in Single AF and Continuous AF mode.

The Nikon D7100 is the fifth DSLR in Nikon’s lineup to feature an AF program that is sensitive down to f/8. This means that the digital camera will continue to focus the lens automatically when a telephoto lens and teleconverter combination results in an effective maximum aperture as small as f/8. Naturally, you can shoot at smaller apertures than this and use automatic focusing since it is just the utmost aperture that is the issue.

Like the D7200, the Nikon D7100 includes a 2,016-pixel RGB sensor that provides data to the Scene Recognition system that guides the metering, white balance and autofocusing systems. You can also take control over the colour of your pictures via the Picture Control modes (Standard, Neutral, Vivid, Monochrome, Portrait and Landscape) with options to adjust the sharpening, contrast, brightness, saturation and hue of the colour modes.

If you habitually shoot raw files, the Image Control modes won’t make much difference to you, but if you shoot JPEGs you should know that the D7200 uses Nikon’s newer Picture Control 2.0 system. This adds a Flat mode for extra dynamic range when shooting video (and processing, or ‘grading’ the movie later) and a Clarity option which increases local comparison for more ‘bite’.

The D7100 can shoot full HD movies at 24, 25 or 30 fps, but if you want faster frame rates (for slow motion) you have to swap to the 1.3x crop mode. Even then, the camera has two swaps to lower-quality interlaced video.

The D7200 offers advantages here, too. Again, you need to swap to the 1.3x crop mode, but now it is possible to shoot 50/60p (progressive) video – one of the advantages, we assume, of the more powerful Expeed 4 processor chip.

If you are interested in video, the improvements in the D7200 probably do make it worth the difference in price. It also offers Auto ISO adjustment when shooting videos in manual setting, clean HDMI output to an external recorder (at the same time as recording video to an internal memory card too) and Zebra mode for warning against overexposed highlights.

Performance

Nikon is aiming the D7100 squarely at enthusiast photographers, and these users like to shoot a bit of everything, from landscapes to sport and macro subjects to wildlife with everything else in between. Consequently, the Nikon D7100 needs to be an all-rounder.

With its 51 AF points and 6 or 7fps continuous shooting rate, the Nikon D7100 seems like a good choice for sports and wildlife enthusiasts, but even with a Class 10 SD card installed it has a relatively low burst depth.

When shooting DX-format images we were only able to squeeze out around 12-15 Fine quality JPEG images or six raw files before the frame rate dipped below the 6fps maximum.

It only takes just over two seconds to fire off these JPEG shots (or one second for the raw files), so timing is of the essence – not that this will phase most experienced photographers.
This is where the larger buffer capacity of the D7200 will make a big difference, both for raw shooters and even those who are happy to shoot JPEGs. It’s one of the main criticisms of the D7100 for action fans.

On the plus side, the autofocus system in the D7100 (just like the D7200) is fast and accurate, getting the subject sharp in next to no time in most situations and successfully tracking moving objects.

Using the new Nikkor 70-200mm f/4G ED lens with the AF-S TC-20E III 2x teleconverter we were also in a position to confirm that the particular AF system continues to function when the maximum aperture falls to f/8.

And rather than just the central AF point functioning, in half-decent light, the whole array of 51 are operational, although using the 15 cross-type sensors gets the subject in focus quicker than the outer factors. If light levels fall, however, you have to stick with the main AF point.

Our resolution tests indicate that while the Nikon D7100 can’t resolve any more detail compared to the 24MP Nikon D3200 and Nikon D5200 at the lower sensitivity settings, the images look very slightly sharper at 100% on-screen. The images are also a little more naturally sharp straight from the camera, with no sign of haloing and a very smooth loss of detail as the resolution limit is exceeded.

As the sensitivity level is pushed up, the Nikon D7100 manages to record more detail than either the Nikon D3200 or Nikon D5200, but this is at the expense of a little noise. The advantages of the non-anti-aliased sensor design look subtle instead of obvious in this instance.

Comparing high sensitivity images from the Nikon D7100 with those through the Nikon D5200 and Nikon D3200 reveals that the Nikon D7100’s images have quite a bit more chroma sound.

We suspect that Nikon has set the D7100’s processing engine to produce noisier pictures to preserve the detail because that is more likely to appeal to the photographic enthusiasts.

These experienced users are more likely to shoot raw files and process them carefully to strike the right balance between noise and detail resolution than novice photographers, who are more comfortable with the Nikon D3200 and shooting JPEG images.

At ISO 3200 and 6400 the Nikon D7100 generally produces pictures with fine-grain noise without any clumping or the banding that troubles images from the Nikon D5200. As a result, they look good when sized to make A3 sized (16.5 x 11.7-inch) prints and they make excellent monochrome pictures.

There are no surprises with the Nikon D7100’s automatic white balance system since it manages to cope reasonably well with most lighting conditions that it encounters. As usual, though, a custom white balance setting is the best option under mixed or artificial lighting.

In most cases, the camera manages to create vibrant but natural-looking colours, only occasionally over-saturating bright greens once the Landscape or Standard Picture Control options are selected.

The reactions of the D7100’s metering system are a little complex. In many situations, it delivers a perfect result when left to its own devices, but there were quite a few occasions when shooting under an overcast sky during this test that we had to use the exposure compensation control to get the outcome we were looking for.

In most instances, we had to dial in 1/3EV or 2/3EV, but some shots required as much as 1EV extra exposure above what the Matrix metering system suggested. Conversely, on a few occasions, just a little underexposure was required to preserve the highlights in the sky.

Verdict

All things considered, the D7100 is still an attractive offering for enthusiast photographers that centres around the thing that these users value the most – detail. It produces sharp, detail-rich images straight from the camera and noise is well controlled up to ISO 6400.

However, if the detail is your main interest, then the D7200 is better still. The D7100 is as good as its chief rival cameras in the mid-range enthusiasts market, but the D7200 is just that little bit better.
