Canon Patent Application for 18-55mm Lens With Variable Field Curvature

Canon Patent
View Post

Japanese blog Hi Lows Note spotted another interesting patent (2018-159876).

The patent literature describes a 18-55mm lens with variable field curvature and spherical aberrations reduction.

This appears to be a lens with a design suited for an APS-C mirrorless camera. May this come to the EOS M system one day?

  • Zoom ratio: 2.88
  • Focal length: 18.58 – 53.49 mm
  • F number: 3.56 – 5.87
  • Angle of view: 36.32 – 14.32
  • Image height: 13.66 mm
  • Lens length: 126.24 mm
  • Back focus: 11.55 mm

There is a lot of buzz around patents. Mostly for nothing. Patents are foremost a way companies have to secure their R&D efforts (research and development).

More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production in the next years are these:

Canon Patent Application for 360 degree camera with 8 zoom lenses

View Post

LetsGoDigital spotted a rather interesting patent.

The patent literature describes a professional spherical camera system, consisting of multiple cameras that can capture 360 degree images and panorama images.

The eight cameras (one at the bottom and at the top and six divided over the middle axis) are continuously connected to each other. Each camera can zoom individually. They are configured in such a way that the field angle overlap each other, which benefits the stitching process.

As soon as the camera system is switched off again, the eight lens barrels will be closed automatically, so that they remain protected against external influences. A power switch is positioned on the top of the device, as well as a shutter release button and two zoom buttons. The zoom buttons can control one or more cameras at the same time. It is also possible to remotely operate the system via a PC or smartphone.

The Canon 360-degree camera comes with three built-in tripod legs, which can be adjusted individually both in length and angle. In addition, three movable illumination units are installed on the camera system. The battery compartment is located in the lower part of the camera.

Canon RF 24-105mm f/4L IS for EOS R Review (optically above DSLR variant, Photography Blog)

Canon RF 24-105mm F/4L IS Review Canon EOS R

Canon RF 24-105mm f/4L IS at a glance:

  • RF-Mount Lens/Full-Frame Format
  • Aperture Range: f/4 to f/22
  • Super Spectra Coating
  • Nano USM AF System
  • Optical Image Stabilizer
  • Customizable Control Ring
  • Rounded 9-Blade Diaphragm

Photography Blog posted a comprehensive review of the new Canon RF 24-105mm f/4L IS lens for EOS R system.

The Canon RF 24-105mm f/4L IS appears to be another optical masterpiece by Canon.

From the conclusion:

The Canon RF 24-105mm f/4L IS is an excellent standard zoom lens that optically is a step above the equivalent DSLR variant, the Canon EF 24-105mm f/4L IS II, which incidentally is one of Canon’s most popular lenses.

The RF 24-105mm offers a very versatile focal range whilst being tack-sharp from 24mm to 85mm, both in the centre and at the edges of the frame. Sharpness at the far end of the telephoto range isn’t quite as good when shooting wide-open at f/4, but you only have to stop down to f/5.6 to get more than acceptable results. Overall the Canon RF 24-105mm f/4L IS delivers excellent sharpness across the frame at most apertures. Vignetting at wide-open apertures and some barrel distortion at 24mm are the only other real optical issues of note.

Build quality is excellent, certainly up to the usual L-lens standard, with the built-in weather-proofing offering peace of mind in more inclement conditions.
