Sony A7R vs Nikon D800: which full-frame camera should you buy? Oct 17th 2013, 23:01, by jmeyer Looking for a new full-frame camera? The new Sony A7R and Nikon D800 share what is widely believed to be the same 36.3-megapixel sensor, and, in fact, Marcus Hawkins finds their spec sheets match up on a number of levels in his Sony A7R vs Nikon D800 comparison. Sony has announced the Sony A7 and Sony A7R, two new full-frame mirrorless compact system cameras. Big on features but small on size and weight, they share the same design, although there are a couple of key differences that set them apart. The entry-level Sony A7 features a 24.3MP CMOS full frame sensor and an improved Fast Hybrid autofocus system that uses a combination of phase detection (fast) and contrast detection (accurate) autofocus. Aimed at enthusiasts and professional photographers, the Sony A7R gets an upgraded sensor – a 36.4 effective megapixel full frame sensor which does away with an optical low-pass filter (OLPF) for improved sharpness, at the expense of some moire. The Sony A7R’s sensor specification comes close to the Nikon D800, or rather the Nikon D800E which also lacks an OLPF. But can the Sony A7R compact system camera really deliver a performance to rival the leading high-megapixel DSLR? Hopefully our Sony A7R vs Nikon D800 comparison will answer some of your questions… Sony A7R vs Nikon D800 comparison: 01 Sensor resolution The Nikon D800 uses a 35.9 x 24.0mm full-frame (Nikon FX format) CMOS sensor, with a resolution of 36.3 effective megapixels. The Sony A7R’s sensor is widely believed to be the same one as in the Nikon D800. The A7R’s sensor is a 35mm full-frame (Exmor) CMOS sensor offering an effective resolution of 36.4 megapixels. It’s no secret that Nikon has been using Sony-built sensors in its DSLRs, so this is an unsurprising development. If you don’t need the Sony A7R’s huge 36 million pixel resolution (and huge image file size), then the Sony A7 is a better buy. The Sony A7 features a 24.3 megapixel full-frame CMOS sensor, but also includes a low-pass filter (to reduce moire). At the imaging chip level, the Sony A7R and Nikon D800 are essentially equal. Obviously how the signal is processed beyond this has an impact on overall picture quality, and the cameras will produce images with marked differences.

Our extensive Nikon D5300 vs D5100 vs D5200 comparison looks at what each camera can offer.   Our resident Nikon guru, Rod Lawton, of our sister title N-Photo, examines all three cameras, looking at their sensor specifications on down to their construction and battery life. When Nikon announced its brand new D5300 DSLR, it also announced the existing Nikon D5200 and D5100 models would carry on. This gives buyers a tricky choice. All three Nikon cameras are aimed at creative amateurs and people upgrading from compact digital cameras, all three share a compact, lightweight design with flip-out LCD display, and all three offer quite sophisticated photographic controls and effects. So here is a blow-by-blow Nikon D5300 vs D5100 vs D5200 comparison of key specifications so that you can see the differences and decide what’s most important to you. Nikon D5300 vs D5100 vs D5200: 01 Sensor • D5100 16.2 megapixels • D5200 24.1 megapixels • D5300 24.2 megapixels (no OLPF) All three cameras have DX-format CMOS sensors, but where the older D5100 has 16.2 million pixels, the D5200 and D5300 both have 24 million pixels. It’s a sizeable increase, but in real-world shooting you’ll need the best lenses and perfect shooting technique to see the difference. The Nikon D5200 and D5300 are not quite the same, though. In the D5300 the OLPF (Optical Low Pass Filter) has been removed to make very fine detail sharper still. These filters are used to prevent moire interference effects with fine patterns and fabrics, but Nikon has decided that at this level of sensor resolution the gain in sharpness offsets any increased risk of artefacts. Nikon D5300 vs D5100 vs D5200: 02 ISO range • D5100 ISO 100-6400, expandable to Hi 2 25600 • D5200 ISO 100-6400, expandable to Hi 2 25600 • D5300 ISO 100-12800, expandable to Hi 1 25600 The Nikon D5200 kept the same ISO range as the Nikon D5100, despite the increase in resolution, which would normally reduce high ISO performance. The Nikon D5300 goes a step further, expanding the normal range to ISO 12800, but keeping the maximum ‘expanded’ value of 25600. Nikon says this has been made possible by the D5300′s new and more powerful Expeed 4 processor, and cites the high ISO performance as one of the new camera’s key attributes.
