The NX30 aims to be like an SLR — only smaller. Credit: Sean CaptainMirrorless cameras — essentially DSLRs without the optical viewfinder — continue to narrow the gap with traditional DSLRs. Samsung, which stopped making DSLRs in 2008, is nudging its mirrorless offerings a bit farther with its new NX30, introduced today (Jan. 2).
Tom's Guide had a chance to go hands on with a pre-production model of the 20.3-megapixel shooter, and we found several new features to like when comparing against its predecessor, the NX20, as well as Samsung's hugely popular NX300. Samsung hasn’t announced when the NX30 will go on sale or what it will cost; the NX20 currently sells for $550, with lens.
Foremost is the new focusing system. For a long time, mirrorless cameras used the same, sluggish focusing tech found in point and shoots, a technology known as contrast detection. Using the image sensor itself, contrast detection requires the lens to keep hunting, back and forth, for the right position. All DSLRs, in comparison, have a special second focusing-sensor using a much faster method called phase detection.
Samsung was one of the first camera makers to incorporate phase detection into the camera's main image sensor. This first occurred on the company's popular NX300 camera, and now it comes to the higher-performance NX30. (Each camera has a whopping 105 phase-detection points, as well as 247 contrast points.) We found the focus on the pre-production NX30 to be about as fast as on the NX300 — which is to say, really fast. (Samsung claims 80 milliseconds, or eight thousandths of a second, to focus, which seems plausible.)
High-res, flexible optical viewfinder
Probably the biggest stumbling block for a DSLR fan is the lack of an optical viewfinder on mirrorless cameras. For most such cameras, if there is an eyepiece at all (in addition to a screen on the back), it has been a relatively low-res LCD with a painfully noticeable pixel grid. The NX30 takes the resolution up to 1024 x 768 — not a lot for a TV, but plenty for such a tiny screen (and a big improvement on the NX20's 800 x 600).

It doesn't, however, have the lifelike color and detail of an OLED viewfinder, such as in Sony's pro-level A7 and A7r cameras, in which the view just as good as looking through the optical viewfinder of an SLR. (Of course, the A7 series cameras are considerably more expensive, starting at $1,700, without a lens.)
One nifty trick for the NX30 viewfinder is the ability to pull it out about an inch and tilt it straight up, 90 degrees. In this configuration, you look down into the viewfinder while the camera stays pointing straight out — a first for any digital camera. Once we finished chuckling over the unmistakable sexual imagery of the viewfinder extending and then curving upward, we found the feature quite handy. It's great for holding the camera down low — for example, when shooting flowers or items on a table — without having to kneel on the floor. It also allows you to place the camera on a table or railing to stabilize it for a long-exposure night shot — without crouching down to get a preview.
The new viewfinder approximates the benefit of the tiltable screens on the back of cameras such as Samsung's NX300. The NX30 has an even more flexible screen, a 3-inch Super AMOLED that flips out to the left and can swivel 270 degrees for viewing with the camera held down low, up high or even facing you for a high-quality selfie. As on several other Samsung cameras, this OLED is also a capacitive touch screen, allowing you to access many adjustments and even set the focus point for a photo with just a tap. The screen should be about twice as bright as those on the NX20 and NX300 cameras, according to Samsung, though the company hasn't set an official brightness level yet.
Promise of better image quality
Perhaps Samsung's biggest promise for the NX30 is one we haven't yet been able to test — its low-light performance, specifically the ability to preserve more detail, with less graininess, when shooting at high light ISO (light sensitivity) settings. The camera we used did not have final software, and low-light performance can change considerably in the final tweaks before a camera ships out. (The NX30 goes up to a once-stratospheric, now increasingly common, ISO value of 25,600 — essentially night vision.)

But if the promise is true, that in itself would be a reason to get the NX30 over other Samsungs. The NX300, for example, though a generally great camera, disappoints at moderately high ISOs such as 1600, which you'll need for pretty much any indoor photography, without flash. (I used ISO 1600 and 3200 settings with an NX300 to shoot my nephew's basketball game and Christmas play, for example. Both were in fairly well-lit spaces, but they also required fast shutter speeds to avoid blur, thus the need for high ISOs to optimize the light.)

Credit: Sean CaptainThe current Samsung models don't produce grainy images at high ISOs, but they remove the graininess (known as noise) by smearing out a lot of detail, making the photos look a bit like paintings when you zoom all the way in. If the NX30 can retain even a bit more detail, it will make a huge difference when cropping into its photos.
Like other Samsungs, the NX30 is tricked out for wireless capabilities. That includes transmitting data over both 2.4 GHz and 5GHz Wi-Fi frequencies — the latter allowing superfast uploads of images to a smartphone or laptop, as we've seen with other models. The NX30 can share images wirelessly to several nearby smartphones. And if a phone has an NFC (near-field communication) chip, all that's required to pair the devices is a tap. (Otherwise, it's a manual config process.)
Samsung has also updated its remote-control software to a version called Remote Viewfinder Pro. It allows an Android or iOS smartphone with Samsung's app to control nearly any aspect of the camera, including flash, shutter speed, aperture and zoom if the lens has a power zoom. (Some of Samsung's interchangeable lenses have power, in addition to manual zoom control.)
Overall experience of the NX30
From our early hands-on trial, the NX30 seems to be a very capable camera and a worthy rival to a DSLR in this price range. However, it may not feel much different from a DSLR. Unlike the sleek, minimalist designs of many mirrorless cameras, including Samsung's NX300, the NX30 really looks the part of a DSLR — dull black with a big handgrip.
Samsung will likely offer the option of buying the NX30 with the company's excellent 18-55mm zoom lens, with optical image stabilization (OIS), the standard lens included with the NX300. But several other lenses are available, too, including a new 16-50mm OIS lens that collapses to just 1.2 inches (31mm) long when the camera is off — about half the length of the standard kit lens.
