Samsung NV7 Review
Review Date: November 22nd 2006
Ease of Use
With an imposing black metal body and two mysterious rows of unlabelled buttons on the rear, the Samsung NV7 is a radical departure from the normal compact digital camera. 'NV' stands for New Voyage, and in terms of the look and feel of the NV7, Samsung have certainly delivered. Samsung have aggressively stated that they want to become one of the top 3 manufacturers of digital cameras by 2008, with the new NV series leading the charge. Positioned at the top of their Lifestyle range, Samsung's NV series represents a heavy investment in the company's future, and it's a world away from the cheap and cheerful non-descript cameras that the company used to sell.
Back to the NV7, from the front it looks like a stylish but fairly conventional digital camera. Look closely though, and you'll start to see why the NV7 represents a leap forward for Samsung. There's a distinctive blue ring around the NV7's large 7x optical zoom lens (38-270mm), indicating that this is a quality Schneider optic, currently only found on the NV series. Samsung are trying to do something similar to Canon's red ring (used to denote their pro "L" series SLR lenses) and use the blue ring to denote their best quality digital camera products. Note that the lens, which dominates the overall design of the camera, does not retract back into the body, making it nearly 4cms in depth and requiring a small camera bag to carry around. The large zoom range really does open up a lot of photographic possibilities, though, and is a breath of fresh air if you are have previously only used 3x zoom cameras. There is a pop-up flash positioned above the lens, cleverly disguised by the Samsung logo. The small red LED just under the shutter button is actually a powerful focus assist lamp. And there's a minimal but effective vertical hand-grip which ensures that you can hold the camera securely.
The top and bottom of the Samsung NV7 are more conventional. There's a Power button, tactile Shutter button and a conventional mode dial on the top for selecting the various shooting modes (more on these later). On the bottom are a metal tripod mount, docking port for the optional camera cradle, and the battery/memory card compartment. The rear of the camera is where things really get interesting. There's a large 2.5 inch LCD screen surrounded by a vertical row of 6 square buttons on the right and 7 buttons on the bottom. Only one button is labeled, the OPS/Back button, and there's also a round Play button. The rocker-style zoom lever becomes the zoom button when viewing images that you have taken, whilst the metal camera strap eyelet cleverly doubles up as a convenient place to hold the camera with your right thumb. So what do those unlabelled buttons actually do? Samsung call them Smart buttons, briefly explaining in the User Guide that they are "used for shifting the menu cursor to select or for confirming the selected menu". Not the greatest of explanations, I'm sure you'll agree!
Overall the Samsung NV7 is superbly built, marking this out as a premium product. The metal body feels indestructible, everything is well-positioned, and all of the various controls are designed and finished to a high standard. Even the pop-up flash unit, usually something of a weak-point, has a positive action and fits well when it's not in use. The flash unit is well-positioned above the lens, helping to avoid the effects of red-eye, and it is actually quite a powerful unit in terms of output. The Samsung NV7 is definitely a camera that you will want to show off to friends and family, and one which should survive more than a few bumps and scrapes.

What Samsung have actually done is replace the conventional main menu system that most cameras have (usually accessed via the Menu button) with a context-sensitive system that is always shown on-screen. Depending on which shooting mode is currently selected, each button corresponds to a specific option, for example auto-focus mode, which is represented by an icon on the LCD screen. You simply press the corresponding vertical or horizontal button to display and select the sub-options for that function. When I first saw the NV series back in June, you had to press each button to highlight it. In the final release, Samsung have also added the ability to scroll through the options by simply moving your thumb up or down, left or right across the touch-sensitive buttons. Very cool, although perhaps not entirely necessary.
What's more important is that being able to see the entire menu system onscreen makes it much easier to understand and access. You no longer have to try and remember which menu a particular option is in. The downside is that the icons, although fairly small and unobtrusive, are displayed all the time, overlaid on top of the live image preview. If you find this really irritating, Samsung have provided a solution in the Setup menu. Simply change the OSD Set option to Hide, and the icons will disappear from the screen after 3 seconds of non-operation, and then instantly re-appear when you press any of the smart buttons again.
Initially I found Samsung's touch sensitive smart button system to be more revolutionary than effective, but once I'd discovered the Hide option and used it for a while, it became a lot more intuitive, making the various menu options much more accessible and speeding up the operation of the camera. It's a very brave step by Samsung as it may put some buyers off (particularly as it takes some time to get used to), but on the whole it's a great idea. There are a couple of points of weakness though. In some shooting modes there are simply more options that there are buttons. Samsung have addressed this by making the bottom-right button toggle between two rows of options. Press it once to display and choose the second row, press it again to return to the default row. It kind of works, but you do have to try and remember which options are in the second hidden row. More importantly, the touch-sensitive buttons aren't the most precise way to select the options which use on-screen sliders, such as Exposure Compensation and in particular Shutter Speed.

The Samsung NV7 has a couple of features designed to combat camera shake. This camera has a true optical image stabilisation mode, dubbed OPS, which moves the built-in sensors in the opposite direction to the movement of the lens. Select one of the two different OPS modes by pressing the button on the back of the camera, and the Samsung NV7 automatically compensates for camera shake, which is a slight blurring of the image that typically occurs at slow shutter speeds. There are two different modes, Mode 1 is only on when you press the shutter button and Mode 2 is on all the time, including image composition. In practice I found that it does make a noticeable difference, as shown in the examples on the Image Quality page. You don't notice that the camera is actually doing anything different when anti-shake is turned on, just that you can use slower shutter speeds than normal and still take sharp photos. However, what Samsung gives you in the form of an effective anti-shake system, it takes away by only providing a limited effective ISO range of 100-200. This essentially means that you really need to leave the anti-shake system turned on all the time to compensate for the slow shutter speeds, especially as ISO 400 exhibits a high level of noise (see the Image Quality page), which negates some of the advantages that the anti-shake system offers. Also, for some bizarre reason that perhaps only the Samsung engineers can explain, when you turn the camera off, OPS is also turned off, so that next time you start the camera, you have to remember to turn OPS back on again. As this is such a useful feature, I would have preferred to see OPS always on by default, and certainly for the camera to remember the previous setting.
The NV7 also has an Anti Shake Reduction shooting mode, accessed on the mode dial on the top of the camera. Unfortunately this is less effective than the OPS feature, as the camera automatically chooses a faster ISO speed to try and compensate for slow shutter speeds (and therefore avoid camera shake). It also seems to apply additional in-camera processing, as each image shot using this mode takes a few seconds to process and save. In practice, I found that the NV7 only ever increased the ISO to 200, even when the shutter speed was greater than 1 second, resulting in blurred results. If you are more experienced, you will know how and when to change the ISO speed yourself to compensate for poor lighting. The ASR mode also drastically reduces the menu options available to you. Therefore the Advanced Shake Reduction mode seems to be targeted more at beginners, and is only genuinely useful in certain situations. I would avoid it altogether and use OPS instead.
There are a couple of options on the Mode Dial which are worthy of mention. The first one is the Special Effect mode, which as the name suggests allows you to apply three kinds of effect to your images as you take them. Photo Frame lets you add 9 types of frame-like borders to a photo, Motion GIF takes up to 50 photos and turns them into a single sequence of animated GIF images, and Composite Shooting enables you to combine 2, 3, or 4 different shots in a still image in different configurations. They are all a little bit novel rather than actually being useful, and you probably won't use them too much after you've tried them out a few times.
Much more useful for photographers is the ASM mode, which gives you full control over both aperture and shutter speed. When you set the camera to this shooting mode, the first option on the vertical menu allows you to choose from Aperture Priority, Shutter Priority or Manual shooting modes. In all three modes, when you half-press the shutter button, the camera tells you how under- or over- exposed the resulting image will be based on the current shutter speed and aperture by showing the Exposure Compensation symbol and a plus or minus value, with values greater than +-2 shown in red. It's a simple system that works quite well.

If you have never used a digital camera before, or you're upgrading from a more basic model, reading the easy-to-follow manual before you start is a good idea, although it's not exactly the most in-depth read. Thankfully Samsung have chosen to supply it in printed format, rather than as a PDF on a CD, so you can also carry it with you. The large 2.5 inch LCD screen is the only way of framing your shots, so if you have to have an optical viewfinder, look elsewhere now. Samsung have used a screen with a perfectly acceptable 230,000 pixels which is visible in all but the brightest sunlight. The various icons used to represent the camera settings are clear and legible, which is a good thing given the predominantly visual operation of the camera.
The start-up time from turning the Samsung NV7 on to being ready to take a photo is a little slow at around 3 seconds, and it takes the same time to zoom from the widest focal length to the longest. Focusing is quick in good light and the camera achieves focus most of the time indoors or in low-light situations, even at the 270mm telephoto focal length. The visibility and refresh rate of the 2.5 inch LCD screen are good. It takes about 1 second to store a JPEG image, allowing you to keep shooting as they are being recorded onto the memory card - there is a very short LCD blackout between each image. In the fastest Continuous mode the camera takes 3 frames per second for just 3 frames, which is somewhat limiting. The flash recycle time is also slow - you have to wait for 5 seconds before you can take another flash photo, which is very annoying, and you can't use flash at all in the continuous shooting modes. Overall the Samsung NV7 isn't very quick in terms of operational speed.
Once you have captured a photo, the Samsung NV7 has a good range of options for playing, reviewing and managing your images. You can instantly scroll through the images that you have taken using the touch sensitive smart buttons, view thumbnails and zoom in and out up to 8x magnification. You can view slideshows with audio, set the print order, delete, protect, rotate, trim and resize an image. Different colour effects can be applied to an image and you make a motion GIF file from images that you have taken. You can capture still images from a movie clip and trim a movie to make it shorter. There's a Photo Gallery option on the Mode dial which allows you to organise images into preset albums, view by date and playback images in a slideshow with music and various effects. Note that there is no histogram available during either shooting or playback.
In summary the Samsung NV7 is a truly innovative, stylish and extremely well-built digital camera with a versatile focal length that is on the whole easy to use. The new menu system does take a while to get used to and won't be to everyone's taste, but it does work surprisingly well.
