Is this camera as good as its lens?<\/strong><\/p>\n

\"\"<\/figure>\n

It\u2019s an axiom of photography that a camera is only as good as its lens. You may have the world\u2019s highest resolution sensor, the fastest auto-focus, perfect metering and flawless noise control, but without a decent lens it\u2019s all for nothing. That\u2019s not to say that you can\u2019t have a terrible camera with a good lens (although it\u2019s rare), it\u2019s just that you can\u2019t have a good camera with a bad lens.<\/p>\n

\n
\nSamsung is clearly aware of this. The lenses on its better cameras bear the name of the renowned German optics company Schneider Kreuznach, and I\u2019ve found them to be among the best lenses on any digital cameras. Sometimes when a modern product bears a prestigious and historic German name, it is simply because a large Japanese company has bought the right to use that brand name on its own products, or even owns a large interest in the German company. However, as far as I\u2019m aware, Samsung\u2019s lenses are actually made by Schneider Kreuznach (Jos. Schneider Optische Werke GmbH) in Germany. The same brand is also used by Kodak on many of its higher-end cameras.<\/p>\n

\n
\nThere is a prime example of Schneider Kreuznach\u2019s finest product on this, the Samsung NV7 OPS. It is a high-spec 7.2-megapixel camera launched at the same time as the gorgeous NV10<\/a> which I reviewed last September. It shares many design similarities with the NV10, although there are also many differences. One large and obvious difference is the NV7\u2019s big 7x zoom Schneider Kreuznach Varioplan lens. It has a focal length equivalent to 38 \u2013 270mm, which is a useful range, but even more useful is its maximum aperture of f\/2.8 \u2013 f\/4.0, which is particularly fast for a digital compact. This gives the advantage of faster shutter speeds especially at longer focal lengths. For comparison, the 6x zoom lens on the Canon A710IS, a camera with a broadly similar specification, has a maximum aperture of f\/2.8 \u2013 f\/4.8.<\/p>\n

\n
\nIn fact there aren\u2019t many other cameras with which to directly compare the NV7 apart from the A710IS. As well as its 7.2-megapixel sensor and 7x zoom lens it also features an all-metal body, a full range of manual exposure options, CCD-shift image stabilisation, a pop-up flash and a big 2.5-in 230k LCD monitor screen. It\u2019s an impressive camera from any point of view, but it doesn\u2019t come cheap. Although one retailer has had it listed at under \u00a3165, its retail price is more usually around \u00a3210-\u00a3220. By comparison the Canon A710IS is around \u00a3178, and the Ricoh Caplio R6 is about \u00a3185.<\/p>\n

One feature which the NV7 does have in common with the NV10 is the unusual Smart Touch control system. While its two rows of unmarked black buttons may look daunting at first, it is actually a very quick and easy system to use, and completely eliminates the need for a conventional menu system. When the camera is switched on, icons are shown on the monitor next to each button, indicating functions such as image quality, exposure compensation, ISO setting and more. Simply press the button next to the parameter you wish to change, and a column of options appears. Press the button on the other axis that corresponds to your choice, and it\u2019s done. In aperture priority, shutter priority and full manual exposure modes the Smart Touch system works especially well. Aperture or shutter speed settings are adjusted by stroking your finger along the row of buttons to move an on-screen indicator. It is very quick and precise once you\u2019re used to it.<\/p>\n

\n
\nDespite its stylish exterior and unusual control interface, the NV7 is well equipped for creative photography. In manual mode shutter speeds of 15 seconds to 1\/1500th are available, as are aperture settings from f\/2.8 to f\/7.3 in 1\/3rd EV intervals. It also has matrix, spot or centre-weighted metering, and optional manual focus. There is also automatic exposure bracketing. Thanks to the sculpted front handgrip and the strap lug that doubles as a thumb grip it handles extremely well. Its performance is better than average for what should probably be considered a super-zoom, although it\u2019s a little slow if you\u2019re used to style compacts. It starts up in a fraction under three seconds, and shuts down again in just under two. In single-shot mode it has a shot-to-shot time of just under three seconds, while in standard continuous mode it can shoot at about 1.3 seconds per shot. There is also a high-speed burst mode that fires off three shots in just under two seconds, as well as a motion capture mode which shoots up to 20 frames at 1024 x 768 resolution and 7.5 frames per second. <\/p>\n

\n
\nOther performance figures are also good. In video mode the camera can shoot at 640 x 480 resolution at 30fps, and the zoom lens can be used while filming. The camera is powered by an 860mAh battery which is larger than average for a compact camera, although Samsung makes no specific claim for its duration. I took over 90 shots on a full charge and the battery indicator was still reading as full. As for storage capacity, a freshly formatted 1GB card provides enough space for at least 270 shots at maximum quality, although it should be noted that the NV7 is not compatible with SDHC cards.<\/p>\n

The moving CCD image stabilisation system is presumably Samsung\u2019s own, although it operates on the same principal as systems used by Pentax and Sony. Motion sensors and tiny actuators move the CCD in response to any camera vibration, allowing the camera to be used hand-held at shutter speeds lower than would otherwise be possible. The Samsung system has two modes, one which works only when the photo is taken, and the other which works continuously while the shutter button is half-pressed, giving a stabilised view on the monitor. In this mode you can actually hear it working as a high-pitched buzzing noise. The system definitely works, but I found that it wasn\u2019t quite as effective as other manufacturers\u2019 image stabilisation systems. It provides a reliable one stop of extra low-speed stability, but pushing it to two stops proved to be less reliable.<\/p>\n

\n
\nAs might be expected the lens performs superbly, producing excellent sharpness across the entire frame at all focal lengths, with minimal wide-angle barrel distortion. Colour rendition and exposure are also excellent, although dynamic range is somewhat limited, with little shadow detail and some burned-out highlights. However the NV7 does have a major problem with image noise, and I\u2019m not talking about the buzzing OPS system. Even at the lowest ISO setting and normal shutter speeds there was visible chromatic noise (random red\/green mottling) in the darker and mid-tone areas of the picture and luminance noise elsewhere. The 7MP image files average just over 3MB, which is a bit on the small side, and there is some evidence of image compression on most images even at the maximum quality setting. This is the fault of the image processing system, which is very disappointing. It could have been so much better.<\/p>\n

\n
\n\u201d\u2019Verdict\u201d\u2019<\/p>\n

The Samsung NV7 OPS had the potential to be an outstanding camera, with a superb lens, great styling, adequate performance and a useful range of features including image stabilisation. However the sub-standard image processing system and resulting image noise problems really let it down.<\/p>\n

\u201dOver the next few pages we show a range of test shots. On this page the full size image at the minimum ISO setting has been reduced to let you see the full image, and below that a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality.\u201d<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\nEven at the lowest ISO setting there is colour speckling plainly visible.<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\nAt 200 ISO the noise is worse, and the level of fine detail is much lower. Look at the lettering on the central banner.<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\nAt 400 ISO the image quality is very poor, and the colour noise has resulted in a green tint over the whole image.<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\nAt 800 ISO the image quality is so poor as to be almost unusable, and there is almost no fine detail left.<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\nUnsurprisingly 1000 ISO is slightly worse than 800 ISO.<\/p>\n

\u201dA range of general test shots are shown over the next two pages. In some cases, the full size image has been reduced for bandwidth purposes, and a crop taken from the original full resolution image has been placed below it to show the overall image quality. Some other pictures may be clicked to view the original full-size image.\u201d<\/p>\n

\n

\n
\nHere\u2019s my usual detail test shot, the West Window of Exeter Cathedral. See below for a full res crop, or click to see the whole picture.<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\nThe lens produces plenty of detail, but the sensor and image processor simply can\u2019t take advantage of it. The shot is spoiled by image noise and compression.<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\nAgain the lens performs well, producing very little barrel distortion at wide angle.<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\nThis corner crop from the above image shows excellent corner sharpness.<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\nThe wide-angle end is equivalent to 38mm.<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\nThe 7x zoom lens has a telephoto setting equivalent to 270mm, great for pulling out details in a scene.<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\nThe dynamic range isn\u2019t exactly brilliant\u2026<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\n\u2026but at least there\u2019s no purple fringing.<\/p>\n

\n
\n\u2014-<\/p>\n

\n
\nColour rendition is superb.<\/p>\n
