Does The Canon EOS RP Have A “Left Eye Issue”?

Canon Eos Rp Best Mirrorless
View Post

Is this real? Photographer Michael the Maven made a short video where he points to what he feels is a “left eye problem” some Canon mirrorless cameras have.

Basically, Michael the Maven complains about the ergonomics and the user interface of the Canon EOS RP. He writes:

The left eye problem deals with cameras which lack a joystick and are asking photographers to use their right thumbs on the touch screen while looking through the viewfinder to move their focusing squares. The left eye problem is not unique to Canon, the Sony A6400 has the same issue, as well as a few other cameras. The reason Im picking on Canon is because I have seen this 3 times now on the Canon R, RP and M50.

Anyone made comparable experiences with Canon cameras?

Sigma Announces Pricing & Availability for Sigma Mount Converter MC-21

Available in April 2019, the new accessory ensures compatibility of the Sigma lenses in EF and SA mounts with the L-Mount camera systems.

Ronkonkoma, NY – March 29, 2019 – Sigma Corporation of America, a leading still photo and cinema lens, camera, flash and accessory manufacturer, today announced pricing and availability for the new Sigma Mount Converter MC-21, offering photographers a wider range of lens options for L-Mount cameras from Sigma, Leica and Panasonic. The SigmaMC-21 will start shipping in April 2019 and will be priced at $169.00 USD for Sigma SA-L mount and $249.00 USD for Canon EF-L mount.

Features
The Sigma Mount Converter MC-21 allows for Sigma’s SA mount and Canon EF mount lenses to be used on L-Mount camera bodies. By attaching MC-21 to a Sigma SA mount or Sigma Canon EF mount lens, it becomes compatible with the L-Mount camera system without compromising usability and image quality. The development of Sigma MC-21 increases the number of interchangeable lenses manufactured by Sigma to be used with the L-Mount systems by 29, offering a total of 40 lens choices, including 11 DG Art primes with native L-mount. The addition of MC-21 to the Sigma accessory lineup will increase the accessibility of the L-Mount system and further Sigma’s role in the strategic L-Mount Alliance alongside Leica and Panasonic.

The full list of compatible lenses and technical specifications can be accessed here and product imagery can be downloaded here.

Pricing
The lower price for the Sigma MC-21 in Sigma SA-L mount reflects the company’s appreciation for the loyal Sigma camera users as the MC-21 in Sigma SA-L mount allows for Sigma SA mount lenses to be used on any L-Mount camera body. Eventually, Sigma will aim to replace its SA mount lenses with the native L-mount versions, but until then, Foveon shooters can rely on the existing offering of Sigma MC-21 at a lower price point to ease the transition to the new system.

Canon Patent For Stacked Sensor Technology

Canon patent application US20190096931 describes a stacked sensor. If you want to lear more about how a stacked sensor works, this article might help.

From the patent literature:

In CCD type and amplification-type solid-state image pickup devices used for digital still cameras, camcorders, and the like, in order to obtain high definition images, the sizes of pixels are required to be reduced. However, as the sizes of pixels are reduced more and more, a light receiving area of a photoelectric converter, in a pixel, detecting light is decreased, and the sensitivity is decreased. 

Canon Patent For 8-15mm Fisheye Lens For APS-C Mirrorless

Canon Patent
View Post

Canon patent application US20190094490 describes the optical formula for an 8-15mm fisheye lens. Given the back focus distance this is most likely a lens for the EOS M system.

From the patent literature:

In order for a zoom lens to have a wide angle of view and achieve high optical performance across the entire zoom range and the entire object distance range, it is important to appropriately set the elements constituting the zoom lens. For example, it is important to appropriately set the zoom type (the number of lens units and the refractive power of each lens unit), the lens configuration, and the lens unit selected for focusing, and so on. 

If these configurations are not appropriate, achieving a wide angle of view will increase the size of the whole system and also increase the variations of various aberrations caused by zooming and focusing. It will therefore be difficult to achieve high optical performance across the entire zoom range and the entire object distance range. 

For example, for a fisheye zoom lens having an imaging half angle of view of 85 degrees or more, a meniscus lens having an extremely strong negative refractive power needs to be disposed closest to the object side within the first lens unit in order to take light rays into the zoom lens from such a wide angle of view. Generally, lenses in a first lens unit not only have strong refractive powers but also have large effective diameters. Thus, when it comes to a fisheye zoom lens, its first lens unit is heavy and large as well. Then, if the entirety or part of the first lens unit (the closest lens unit to the object side) is used as a focus lens unit, quick focusing will be difficult.
