Summary: That Canon EOS 5D Mark III is the celebrated successor to the wildly popular 5D Mark II, packing in several significant improvements, new technologies, but only a 22MP sensor. We know that pixel count isn't everything (and we implore that you feel the same) but Canon claims that the sensor employs a design different from its predecessor. Then there is the Digic 5+ chip for processing and a 51-point AF sensor.
Pros: Amazing AF system, Good high ISO still and video performance, lighter body with weather sealing, Silent jog dial for uninterrupted audio recording
Cons: Quite pricey compared to the camera it replaces and competes with, Noise in video is quite unpleasant (above ISO 8000 in low light)
Conclusion: The Canon EOS 5D Mark III looks a lot like its predecessor on the outside, but offers plenty of improvements under the hood. It's a solid option for advanced shooters with an investment in Canon glass, but doesn't match the rapid-fire shooting capabilities of the EOS-1D X or Nikon D4.
Pros: Compact for a full-frame SLR. 22-megapixel resolution. Large optical viewfinder. Bright, high-res rear LCD. Fast autofocus. 6fps continuous shooting. Excellent high ISO performance. 1080p video recording.
Cons: Expensive. Slow focus in Live View and Video modes. No built-in flash. Not compatible with EF-S lenses.
Summary: The Canon EOS 5D Mark III is the continuation of the 5D line which introduced the first full-frame DSLR without an integrated grip, bringing quality images to a smaller form-factor than previously possible. The new 5D Mark III follows the tradition by reworking the inside of its predecessors to provide much improved image quality and a new ultra-fast autofocus system ideal for action photography.
Pros: Very low image noise, Excellent image sharpness, Very accurate colors, Good automatic white-balance, Spectacular subject tracking autofocus, Lightning fast autofocus, Full choice of exposure modes for movies, Class-leading continuous buffer, Large viewfinder with 100% coverage, Highly customizable user-interface, Virtually no shutter-lag, Quick and responsive, Solid construction
Cons: Underexposes often, Expanded ISO of limited use, Low rear control dial, Rear dial prone to accidental changes, Complex interaction between AF and lenses, Slow instant review, Slow to power-off due to sensor cleaning
Excerpt: You’ve seen this camera’s predecessors, the Canon EOS 5D Mark II and 7D and Nikon’s D90, everywhere or, least you’ve seen their product on TV or at the movies. What made many industry players sit up and look closely was the use of the Canon EOS 5D Mark II to shoot the finale of the series House, produced entirely on this camera.
Summary: The Canon EOS 5D Mark III is not only a very capable photographic tool in almost all areas, it's also fun and exciting to shoot with. The only downside are the slightly soft and overprocessed out-of-camera JPEGs. This is only visible at pixel-level but we would expect most of the camera's target group to shoot raw anyway.
Pros: Good resolution and detail in raw files, Good color and tonality across the ISO range, Reliable metering even in difficult contrast situations, Very responsive and snappy operation, thanks to new Digic 5+ processor, 6 frames per second continuous shooting with good buffering, Excellent build-quality with magnesium shell and weather-sealing, Intuitive user interface and good ergonomics with large number of external controls, Very comprehensive user interface customizat...
Cons: Destructive noise reduction results in mushy JPEGs, even at base ISO, Visible sharpening artifacts at default settings, Heavy-handed noise reduction leads to lack of low-contrast detail at higher ISOs, Distortion correction not available 'on the fly', Built-in microphone only monaural, Soft video output with less dynamic range than stills, No built-in AF illuminator
Conclusion: 5D owners may well have felt that the MkII didn't really do enough to grab their attention because it didn't address enough of its older sibling's deficiencies. The increased resolution was attractive, but again not enough on its own. The MkIII, however, does just that, with improved handling, an impressive range of new features and fantastic image quality.
Conclusion: A Canon EOS 5D Mark III parece muito com sua predecessora por fora, mas oferece muitos melhoramentos sob o capô. É uma opção sólida para fotógrafos avançados com um investimento em lentes Canon, mas não rivaliza com as capacidades de disparo rápido do EOS-1D ou Nikon D4.
Pros: Compacta para um SLR full-frame. Resolução de 22 megapixels. Largo visor ótico. LCD traseira nítido com alta resolução. Autofoco rápido. Disparo contínuo de 6fps. Excelente e alto desempenho ISO. Gravação de vídeo 1080p.
Cons: Caro. Foco lento nos modos Live View e Vídeo. Sem flash integrado. Não é compatível com lentes EF-S.
