Canon EOS 1D Mark III vs EOS 70D Overview and Optics

The Canon EOS 70D wins in the optics comparison with a score of 58/100, while the Canon EOS 1D Mark III scores 50/100. Both cameras share some common specifications, such as having a CMOS sensor, no image stabilization, and compatibility with Canon lenses. However, there are significant differences that set them apart.

The Canon EOS 70D has a higher megapixel count at 20.2, compared to the 10.1 megapixels of the Canon EOS 1D Mark III. This higher resolution enables the 70D to capture more detailed images. Additionally, the 70D has a newer and more advanced DIGIC 5+ processor, which contributes to better image quality and faster processing speeds.

Despite having a lower score, the Canon EOS 1D Mark III has its advantages. The camera has a faster shooting speed of 10 frames per second, compared to the 70D’s 7 frames per second. This makes the 1D Mark III more suitable for capturing fast-moving subjects. Additionally, the 1D Mark III has a slightly higher DXOMARK sensor score of 71, compared to the 70D’s 68, indicating better overall image quality.

When considering the sensor sizes, the Canon EOS 1D Mark III has an APS-H sensor, whereas the Canon EOS 70D has an APS-C sensor. The larger sensor size of the 1D Mark III can contribute to better low-light performance and dynamic range.

To conclude, the Canon EOS 70D outshines the Canon EOS 1D Mark III in terms of optics, mainly due to its higher megapixel count and more advanced processor. However, the 1D Mark III offers a faster shooting speed and a larger sensor size, making it a suitable option for specific photography needs. Ultimately, the choice between these two cameras depends on the photographer’s preferences and requirements.

Canon EOS 1D Mark III vs EOS 70D Storage and Battery

The Canon EOS 1D Mark III outperforms the Canon EOS 70D in storage and battery with a score of 84/100 compared to the 70D’s 37/100. Both cameras lack USB charging and accept SD/SDHC memory cards. The 1D Mark III has an advantage with two memory card slots and compatibility with Compact Flash (Type I or II) cards. Its battery life of 2200 shots is significantly longer than the 70D’s 920 shots, utilizing the LP-E5 battery type.

In contrast, the EOS 70D accepts a wider range of memory cards, including SDXC, but has only one memory card slot. Its battery type is LP-E6, and although it has a shorter battery life, it may still be sufficient for casual users.

Considering these factors, the Canon EOS 1D Mark III is the superior choice for those prioritizing storage and battery capabilities. The Canon EOS 70D may be suitable for casual users who require less demanding battery life and storage options.
