Canon 5D Mark III advantages over Pentax MX-1

• Larger sensor
  35mm vs 1/1.7 inch
  More sensor area. Bigger is (generally) better.
• Eye-level viewfinder
  Eye-level vs Rear display only

• Bigger pixels
  ~ 6.25 vs 1.90 microns
  Better low-light and dynamic range (all else equal)
• Fast startup
  ~0.50 vs 2.2 sec
  Faster startup lets you catch the moment
• Better color depth

  Better color depth

  Color depth refers to the number of unique colors that a sensor can faithfully capture. Cameras with better color depth will demonstrate smoother transitions from one color to the next, and avoid "banding" in areas with subtle shading. (Blue skies are an example of where you might see color banding.)

  More color depth is generally better, but you'll struggle to notice a difference between two cameras with less than 1 bit of difference. Color depth above 22 bits is considered excellent.

  Capture richer, more accurate colors
• Higher effective ISO

  Higher effective ISO

  Maximum effective ISO is an estimate of the highest sensitivity at which a camera can capture excellent quality photos.

  Cameras with higher effective ISO will be better choices for indoor photography, night shooting, and indoor sports photography, especially if you intend to make large prints.

  Longer stills battery life

  Cameras with longer battery life can take more photos before exhausting their batteries.

  Special note: The measurement standard for battery life stipulates that if a camera has an internal flash, it must be used for 50% of photos taken. For this reason, comparisons of one camera with an internal flash to another without will not be comparable
