Canon RF 50mm f/1.2L Review (a seriously good lens)

Canon RF 50mm F/1.2L Review Canon Rf Lenses

Here is a Canon RF 50mm f/1.2L review. This lens for the EOS R system is an optical masterpiece, heavy, bulky, and pricey. Never the less, the Canon RF 50mm f/1.2L is a remarkable lens, made to showcase the capabilities of the RF mount

Ted Forbes of The Art of Photography discusses all the goods and amazing features of the super fast Canon RF 50mm f/1.2L. The lens is also pretty unique, as Ted Forbes lines out.

Canon started big with their first round of RF mount lenses for their mirrorless system. The Canon RF 50mm f/1.2 L is a seriously good lens. Its versatile enough to be very sharp, but can also shoot wide open for some gorgeous and often abstract bokeh rendering. Building on the EF 50mm f/1.2, Canon corrected many of the aberrations and give us a sharper, high resolving lens. This does come with some tradeoffs – this lens is big. Its also very heavy and the price is not cheap. But if you’re willing to sacrifice some of the conveniences of portability for image quality – this lens is well worth the entry price.
Its also worth noting at the time I’m filming this – there is no equivalent to this lens in any mirrorless system. Nikon only have a 50mm f/1.8 and Sony have several options – but only at f/1.8 and f/1.4. This is a unique lens with a beautiful rendering and performance.

Enjoy the video, and thanks for being here and reading.

Canon RF 50mm f/1.2L Review Sample Photos (D. Abbott)

Dustin Abbott posted a set of Canon RF 50mm f/1.2L review sample pictures.

The Canon RF 50mm f/1.2L is one of the “boutique lenses” for the EOS R full frame mirrorless system, i.e. a lens made to show off the capabilities of the RF mount. No reviewer had ever to be unhappy with the performance of this lens.

Dustin Abbott says:

Canon has also started to deliver on what was clearly the greatest strength of the platform – the new RF mount and all its potential. While the bargain lenses for the RF mount are still few (though thankfully some third party support has started to come), Canon has delivered a number of their very best lenses yet on the RF mount…and one of those is the Canon RF 50mm F1.2L, which is one of the best performing 50mm lenses, well, ever. It’s large, heavy, and expensive, but is also one amazing piece of kit.

Canon Patent Application Roundup (dual sensor cam, shrinking MILCs, RF 50mm f/1.8, RF 14-28mm f/2)

Some new Canon patent applications, all spotted by Canon News.

Canon Patent Application 2019-184921 discusses how to further shrink the size of a mirrorless camera:

An object of the present invention is to provide a technique for suppressing an increase in the size of an image pickup apparatus due to the arrangement of a motor for driving a shutter.

Canon Patent Application 2019-186594 deals with the idea of a camera with dual sensors. Might produce some pretty cool HDR photography:

The half mirror 103 splits the imaging light beam (subject light beam) that has passed through the imaging optical system 102 into a first light beam and a second light beam. The first image sensor 104 and the second image sensor 105 receive the first light beam and the second light beam, respectively. The first image sensor 104 and the second image sensor 105 are constituted by a CCD image sensor, a CMOS image sensor, or the like. The first image sensor 104 and the second image sensor 105 have an image pickup pixel and a focus detection pixel for autofocus using a phase difference detection method. The MPU 106 includes a CPU and a memory that stores a program executed by the CPU, and functions as a control unit that controls the overall operation of the camera body 101. Further, the MPU 106 controls the driving of the photographing lens 102b via the lens driving motor 108.

Can the Canon EOS R system miss a Nifty Fifty lens? It looks like this has not to happen. Canon patent application 2019-184748 discusses optical formulas for an RF 50mm f/1.8 lens. Here comes the Nifty Fifty:

F-number 1.85
half angle (in degrees) 23.95
image height 21.64
total lens length 58.55
BF 20.94

Focal length 48.70

Canon patent application 2019-0324229 discusses optical formulas for an RF 14-28mm f/2 lens for the EOS R system

Focal length 14.42 19.78 27.16

KamLan 50mm f/1.1 II Lens for Canon EOS M Released

The KamLan 50mm f/1.1 II lens for mirrorless systems has been officially released. It sells at $159.99 and can be pre-ordered at Adorama or KickStarter

The “Kamlan 50mm F1.1 MK2 APS-C lens” has a super large, bright f/1.1 aperture with 11 circular aperture iris that allows for great results in extreme low light conditions and also the ability to create beautifully creamy backgrounds. Brand new optical design can help you get great sharpness in all aperture range.
One of the key strengths of the Kamland 50mm f/1.1 MK2 is its high degree of color accuracy and richness. Unlike some normal large lenses, it does not introduce too much color cast to images but instead delivers a neutral, accurate color rendition even wide open. You can easily create great 3D effect and rich sense of atmosphere for your images.
Kamlan 50mm F1.1 MK2 features with dual high index of refraction element groups. It can calibrate the spherical aberration effectively. The result is your images will be sharp from minimum distance to infinity.
Further extending the flexibility of the lens is the ability focus down to just 0.4m (1.3ft), allowing you to fill the frame with your subject and throw the background dramatically out of focus.
Kamlan 50mm F1.1 MK2 features a larger diameter element with high index of refraction glass to help eliminate the onion rings. The whole defocus area is smooth and creamy.
