Comparison: G1X vs 7D – Surprising!

 

    

I found an interesting post on dpinterface with an in-depth image comparison between Canon’s G1 X and EOS 7D – two players in different leagues. Lets first see the basic tech specs for both cams:

  • EOS 7D
    • 18.0 Megapixels
    • 3.0″ LCD
    • HD Video Recording
    • Selectable Video Exposure + Frame Rates
    • Dust & Weather Resistant
    • 100% Viewfinder
    • Self Cleaning Sensor
    • High Sensitivity (ISO 12800)
    • 8fps Burst Mode
  • Powershot G1 X
    • 14.3Mp 1.5″ CMOS Sensor
    • 3.0″ Vari-Angle LCD Screen
    • 28mm Wide Lens with 4x Optical Zoom
    • DIGIC 5 Image Processor
    • Hybrid Image Stabilizer
    • Optical Viewfinder
    • 12,800 ISO
    • 1080p Full HD Video
    • High Dynamic Range Scene Mode
    • Manual & Numerous Other Shooting Modes
 The next chart illustrates the respective sensor sizes:

Definitely gear aimed at different using-scenarios. Another thing to keep in mind is the difference in aspect ratio of the sensors (G1X 4:3, 7D 3:2).  The lens used on the EOS 7D was the Canon EF 24-70 mm f2.8L USM. So we have a 14MP sensor against a 18MP one, which is also 27% larger than the one mounted on the Powershot G1 X. The comparison in summa:

  • Dynamic range: very close
  • Detail level: 7D clear winner (no wonder: bigger sensor, higher resolution, and – to some matter – an L lens)
  • High ISO noise: not really comparable since on the 7D noise reduction was disabled, which is not possible on the G1 X (NR set to standard). However, high ISO noise is very good on the G1 X. Would have been better to do this comparison using RAW files.

The conclusion:

The Canon PowerShot G1X actually produces image quality that is very close to that of the Canon EOS 7D; not identical but very similar. The Canon G1X produces photos with, overall, better out-of-the-camera sharpness but less color saturation and slightly less detail, though the difference isn’t really obvious unless you inspect really fine detail as shown in the examples above. Even that can be overcome by shooting in RAW or tweaking the camera’s settings to increase saturation and sharpness.

The PowerShot G1X definitely outperforms other prosumer models and compact cameras of its class thanks to its premium larger-than-average image sensor. If you want a relatively compact (though the camera will not fit in your pants pocket at all!) camera that delivers digital SLR or ILC level image quality without the hassle of something the size of an actual SLR, consider taking a look at the Canon PowerShot G1X.

Hold one, there is more. The same guys did also a comparison between the video modes of the Powershot G1 X and the EOS 7D. The Powershot G1 X comes with 1080 full HD, stereo recording, 24 fps (720p standard HD and VGA give you 30 fps). The EOS 7D comes with 1080 full HD, mono recording, 24 or 30 fps at 1080p. Ok, let’s go with the videos, first the one shot with the Powershot G1X.

Next, the video made with the EOS 7D (1080p at 30fps).

All in all, the Powershot G1 X doesn’t stay that much behind the EOS 7D. Read the post here.
