The main differences between Canon 5Dmark2 and 5Dmark3 are as follows:
Parameter comparison:
Main key differences:
5D MarkIII adopts a new generation 22.3 million pixel COMS sensor, corresponding to the 21.1 million effective pixel CMOS used by Canon EOS 5D Mark II. Although the pixel improvement is limited, the newly designed CMOS will be one step closer to the 5D Mark II in terms of imaging details, color reproduction and picture level. .
Image processor improvement Digic 5+? vs? Digic 4
Canon EOS5D Mark III uses the DIGIC 5+ processor originally used in EOS 1DX, and its performance is about DIGIC5 processing 3 times the processor, significantly improving operating efficiency in terms of image quality and high-speed image processing. The 5D MarkII uses a DIGIC 4 processor.
The old Canon EOS 5D Mark II has a sensitivity range of 100-6400 that can be expanded to ISO50-25600, while the new EOS 5D Mark III can use the DIGIC 5+ processor to achieve a minimum sensitivity of 100 and The maximum sensitivity is 25600, which can be expanded to ISO50-102400. EOS5D Mark III uses the powerful computing power of the DIGIC 5+ processor to achieve high-sensitivity image quality performance that is greatly improved compared to 5D MarkII.
The slow focusing speed of the 9 visible focus points plus 6 hidden point focus system used by Canon EOS 5D Mark II has always been criticized. The focus system of the Canon EOS 5D Mark III has been completely upgraded, using the same 61-point focus system as the Canon EOS 1Dx. In this focusing system, 41 of the 61 focus points use high-speed, high-precision cross-diagonal points, making the Canon EOS 5D Mark III's focusing speed not only fast and accurate, but also not limited by the shape of the object being photographed. , even in extremely harsh environments, you can still accurately focus and shoot. In terms of light metering, Canon EOS 5D Mark III uses an iFC 63-zone dual-layer metering sensor, making the 5D Mark III's light metering more accurate.
The Canon EOS 5D Mark III uses a 1.04 million-pixel 3.2-inch LCD screen with Claer View II technology. Compared with the EOS 5D Mark II's 3-inch 920,000-pixel LCD screen, it is not only 0.2 inches larger in size, Moreover, the 1.04 million pixels and Claer View II technology also make the photos more detailed and the color reproduction is better when viewed back.
The difference in viewfinder field of view has an important impact on shooting and composition. Canon EOS 5D Mark III uses a viewfinder with a field of view of 100%. Compared with the viewfinder of the old Canon EOS 5D Mark II with a field of view of 98%, it can achieve a framing effect that is basically consistent with the actual shooting range, while 100% The viewfinder with a wide field of view and 71% magnification is also Canon’s second mid-range model to use this viewfinder after the 7D.
Another drawback of the Canon EOS 5D Mark II is the continuous shooting speed. With the help of the DIGIC 5+ processor, even though the EOS 5D Mark III uses a 22.3-megapixel sensor, it can still achieve continuous shooting of about 6 frames per second, making Canon EOS 5D Mark III great progress in shooting moving objects.
More abundant high-definition video shooting
High-definition video shooting allows Canon EOS 5D Mark II to occupy a place in the field of video shooting. The new Canon EOS 5D Mark III not only inherits the advantages of 1920X1080 high-definition video shooting, but also has a video shooting sensitivity of ISO100-12800, which can be expanded to 25600. It also supports 30 frames per second, 25 frames and 24 frames per second. The new SMPTE timecode support provides more flexible video editing, and also provides more comprehensive help for multi-camera video shooting.
CF and SD dual card support
Compared with Canon EOS 5D Mark II, which only supports CF memory card, the new Canon EOS 5D Mark III officially supports CF card and SD card in terms of storage. SD card dual memory card support, and self-supported UDMA 7 and SDXC/UHS-1 high-speed memory cards. Dual card support and high-speed storage provide strong guarantee for EOS 5D Mark III continuous shooting and high-definition video shooting.
