The Canon EOS 5D Mark III triumphs over the Leica M9 with a score of 65/100 compared to the M9’s 34/100. Both cameras share some general specifications, such as being released in the early 2010s, with the 5D Mark III in 2012 and the M9 in 2009. They also have similar launch prices, with the 5D Mark III at $3,499 and the M9 at $5,500.

The 5D Mark III, a DSLR camera, excels in various aspects. It boasts a larger size (152 x 116 x 76mm) and a heavier weight (950g) compared to the M9’s smaller size (139 x 80 x 37mm) and lighter weight (585g). This difference in size and weight contributes to the 5D Mark III’s sturdiness and durability.

On the other hand, the Leica M9, a mirrorless camera, has its advantages. Its compact size and lighter weight make it a more portable option for photographers on the go. However, the lower score indicates that the M9 may not perform as well as the 5D Mark III in other aspects.

Taking into consideration the scores and specifications, the Canon EOS 5D Mark III proves to be a superior choice for those seeking a robust and high-performing camera, while the Leica M9 may be more suitable for photographers prioritizing portability.

Canon EOS 5D Mark III vs Leica M9 Overview and Optics

The Canon EOS 5D Mark III outperforms the Leica M9 in terms of optics, scoring 67/100 compared to the M9’s 42/100. Both cameras share some common specifications, including full-frame sensor size, lens mounts specific to their respective brands (Canon EF and Leica M), and the absence of image stabilization.

The 5D Mark III’s superiority in optics is evident in several aspects. First, it has a higher megapixel count of 22.3 compared to the M9’s 18, allowing for more detailed images. Second, the 5D Mark III has a faster shooting speed of 6 frames per second, whereas the M9 only manages 2 frames per second. This makes the 5D Mark III more suitable for capturing fast-moving subjects. Third, the 5D Mark III uses a CMOS sensor and a Digic 5+ processor, resulting in a higher DXOMARK score of 81 for its sensor compared to the M9’s CCD sensor and Maestro II processor, which score 69.

On the other hand, the Leica M9 has its own unique advantage in terms of optics. Its Leica M lens mount is compatible with a range of high-quality, renowned Leica lenses, which are known for their sharpness and color rendition. This can potentially provide better image quality despite the lower megapixel count and sensor score.

While both cameras possess strengths in their optics, the Canon EOS 5D Mark III clearly excels in multiple aspects and is the better choice for those prioritizing image resolution, shooting speed, and sensor performance. However, photographers who value the unique characteristics of Leica lenses may still find the Leica M9 to be a suitable option.

Minimum ISO (Native)
Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image.
Maximum ISO (Native)
Refers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise.
Minimum ISO (Expanded)
Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.
Maximum ISO (Expanded)
Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.
Minimum Shutter Speed
The minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory.

Canon EOS 5D Mark III vs Leica M9 Storage and Battery

The Canon EOS 5D Mark III outperforms the Leica M9 in storage and battery, scoring 76/100 compared to the Leica M9’s 21/100. Both cameras share some specifications, such as accepting SD and SDHC memory cards and lacking USB charging capabilities.

The Canon EOS 5D Mark III excels with its two memory card slots, compatibility with SDXC, Compact Flash, and UDMA cards, and an impressive battery life of 950 shots using the LP-E6 battery type. These features provide users with more storage options and extended shooting periods.

On the other hand, the Leica M9 has only one memory card slot and is limited to SD and SDHC cards. Its battery life is significantly lower, providing just 350 shots with the BP-SCL1 battery type. Despite these limitations, the Leica M9 still offers decent storage and battery performance for casual photography.

Considering these factors, the Canon EOS 5D Mark III offers superior storage and battery capabilities, making it a more suitable choice for professional photographers or those who require extended shooting periods and versatile storage options. The Leica M9 may be more appropriate for casual photography or users who do not need extensive battery life and storage flexibility.
