Canon Patent For Liquid Optical Elements (liquid lens)

Liquid optical element

Figure above: When electricity is applied the optical element gets a shape.

Another Canon patent spotted by Egami (translated).

Liquid lenses have a series of advantages over traditional lenses. Beside not having moving parts (and thus less mechanical parts), they respond quicker to electrical signals, they do not have a motor (you thought that USM was the big thing? Think again) and they are naturally much more silent. The lack of a motor also means such a lens needs less electrical power, hence the battery lasts longer. Liquid lenses are most likely going to be employed in compact cameras and/or smartphones. If you want a more scientific description about what liquid lenses are and do, I recommend this article.

It is not the first time Canon files a patent for a liquid lens (and yes, I shamelessly recycled some of the text of my previous post :-) ).

Patent description (machine translated):

  • Patent Publication No. 2013-101227
    • Publication date 2013.5.23
    • Filing date 2011.11.9
  • Canon patent
    • I drive a plurality of pumps
    • Drive pump liquid optical element to hold the end of the interface
    • When applied to the electrodes, electrowetting phenomenon in which the liquid moves to the interface from the drive pump occurs
    • Optical properties are changed by the movement of the liquid
    • By discretely and independently controlled and a voltage, enabling high-speed drive

Head To Head Review: Canon Powershot G15 vs. Nikon Coolpix 7700

Powershot G15

Interesting comparison by photographic authority dpreview.

A head to head comparison of the Canon PowerShot G15 and the Nikon Coolpix 7700, both very popular high end compact cameras for enthusiasts. While it obvious that each one has its strengths and weak points – the G15 has a faster lens (f/1.8) and the 7700 a longer zoom range, just to make an example – the Canon Powershot G15 comes out as the winner – even if with a very small advantage. Let’s see the core specs (taken from B&H‘s product pages)

 PowerShot G15  Coolpix 7700
 12.1MP CMOS Sensor  12.2MP CMOS Sensor
 3.0″ LCD Monitor  3″ Display With 921K Resolution
 5x Optical Zoom 6.1-30.5mm Lens  7.1x 28-200mm Zoom Lens (35mm Equiv.)
 28-140mm 35mm Equivalent Focal Length  f/2.0 Maximum Aperture
 DIGIC 5 Image Processor  High-Speed Shooting at Up to 8 FPS
 1080p HD Video Capture  Subject Tracking Auto Focus
 12800 ISO  19 Scene Modes
 Intelligent IS Image Stabilization  Full-Size Accessory Shoe for Accessories
 10fps Continuous Capture  In-Camera Creative Special Effects
 RAW & JPEG Capture  RAW & JPEG Capture

In the conclusion, different aspects are considered:

  • Design and Handling: While the P7700′s flip-out LCD is appealing, [dpreview thinks] that the G15′s smaller, more rugged body and optical viewfinder give it a slight edge.
  • Features: Canon Powershot G15 is winner
  • Performance: Canon Powershot G15 is winner
  • Movie mode: Coolpix P7700 (thanks to mic input and manual exposure control)
  • Image quality: Coolpix P7700 (by a hair)

The final word by dpreview:

The Canon PowerShot G15 narrowly beats the Nikon Coolpix P7700 in our competition here, but it’s a close-run thing. The G15 offers a fast lens, very good image quality, a compact yet solid body, snappy performance, and plenty of manual controls. And then there’s the optical viewfinder which, while not great, is better than nothing. About the only things on our wish list are an articulating LCD display (like on previous models), faster frame rates in movie mode, and a bit sharper images, though the latter is subjective.

The Canon Powershot G15 gets a Gold Award (76%), the Nikon Coolpix 7700 a Silver Award (75%).
