I updated my overview chart with available high-end cameras. See http://www.dxomark.com/Cameras/Camera-Sensor-Database for detailed benchmark results for specific cameras. As usual, there is a lot of interesting information in such an overview:
- Assuming you care about low light and high dynamic range performance, the best cameras have full-frame sensors (the blue dots). You knew that – right? Well, surprisingly full-frame sensors beat even larger (purple, pink, red) sensors. So don’t bother spending big money on a medium format camera unless you really need the super-high resolution. Or need it show that your equipment is clearly on a price class of its own.
- The so-called APS-C cameras with 1.5x or 1.6x sensors have improved. Examples: the Nikon D5200 and D5300.
- The Sony NEX-5R mirrorless (which is 1.5x) has a slightly higher price than an APS-C SLR, but the body is smaller and the performance is competitive. Mirrorless models should have the same performance as an SLR with a comparable sensor. A mirror doesn’t add image quality – it just makes a click sound like ke-lick.
- Canon still has a long way to go to catch up with its APS-C sensors (1.6x). The Canon 70D performs slightly better than the old Canon 7D, but a comparison to Nikon or Sony tends to be embarrassing.
- Recent Micro Four Thirds cameras (Olympus & Panasonic) have improved and are even ahead of Canon’s APS-C (1.6x) models.
- The Sony RX100 and RX100-II are still doing fine – at least considering their small sensor size (2.7x or 1/1″ ). The Nikon Series 1 is technically not state-of-the art, but nice if you like white or pink gear: it targets a young Asian lifestyle market.
- The premium pocket cameras have improved. Especially the 1/1.7″ sensor models such as the Canon Powershot S120 and G16 and their Nikon equivalents.
- The best deals if you need a high quality model can be found at the top edge of the cloud in diagram “b”: you get the highest quality in that price range. Note that the prices shown are official prices at introduction, and will differ from current street prices. These deals include:
- The Nikon D600 and D610. These are essentially the same camera, but the D610 resolves a dust issue.
- The new Sony A7R mirrorless. Note that this model uses Sony E-mount lenses, but actually requires new Sony full-frame E-mount lenses called “FE”. So it will take a while until there are enough lens options.
- The Sony RX1 and RX1R. These look overpriced (and probably are – although I ordered one myself), but their price does include an excellent 35mm Zeiss f/2.0 lens. On the other hand, they do not come with an optical or electronic viewfinder. These cost about 500 US $ or Euro extra. Lens hood pricing is joke (so look into the Photodiox accessories).
- The Nikon D5200 or D5300. Both have a 24 MPixels state-of-the-art sensor, but the newer one gives sharper images (no AA filter) if your lenses are up to the challenge.
- The Nikon D3200. Also 24 MPixels with state-of-the-art sensor technology.
- The Pentax K50 and K500. A somewhat overlooked brand.
- The Nikon Coolpix P330. A “take me everywhere” camera at a lower price point than the excellent Nikon Coolpix A or FujiFilm’s X-100s models.
Note that some major new camera models are not shown because DxO Labs simply hasn’t tested them yet. These include:
- The new full-frame Nikon Df (with the professional Nikon D4’s 16 Mpixel sensor). It should score about 89 (D4) for $3000 – nice, but not sensational unless you insist on a retro look and feel.
- Most FujiFilm X-Trans models have not been tested. Tests may be delayed because they have a non-standard color filter array (complicating raw conversion). The CFA design allows the sensor to work without a low pass filter. Alternatively, the missing tests may be because FujiFilm is not enthusiastic about their cameras’ DxOMark scores (pure speculation on my part, but the FujiFilm X-100 didn’t score exceptionally well). FujiFilm high-end cameras are getting a lot of attention from serious photographers who prefer small, unobtrusive cameras with a classic mechanical feel.
- The Sony A7. Many people wouldn’t really benefit from 36 MPixels (Sony A7R) without an image stabilizer or a tripod or high-end lenses.
For a detailed explanation of what the benchmark itself means, see http://www.luminous-landscape.com/essays/dxomark_sensor_for_benchmarking_cameras2.shtml. Note that the number of tested cameras has meanwhile increased from 183 to 236 models.
