Canon Might Have a 50mm f/1.8 and a 28mm f/1.8 For The EOS R System On Their Agenda, Patent Suggests

50mm F/1.8

Canon patent application 2019-0113711 (USA) describes the optical formula for an RF 50mm f/1.8 and RF 28mm f/1.8 lens, both for the Canon EOS R full frame mirrorless system.

Focal length 48.50
F-number 1.85
Half angle of view (degrees) 24.04
Image height 21.64
Total lens length 95.00 
BF 15.80

Focal length 28.80
F-number 1.85
Half angle of view (degrees) 36.91
Image height 21.64
Total lens length 80.30 
BF 7.00 

It’s likely Canon will launch these non-L lenses sooner than later. Both are popular focal lengths on full frame, and it’s also likely Canon is set to offer some less expensive (aka budget) lenses for the EOS R system.

Press release:

ZY Optics releases the Mitakon Speedmaster 50mm f/0.95 mark III, designed for Sony FE, Canon RF & Nikon Z cameras

Shenyang China, Apr 17, 2019 – Zhongyi Optics (ZY Optics) have released the new Mitakon Speedmaster 50mm f/0.95 version III for full frame Sony E, Nikon Z and Canon RF cameras.
Offering a natural 50mm perspective along with an ultra-fast f/0.95 maximum aperture, the Mitakon 50mm f/0.95 is a compact prime characterized by its bright f/0.95 aperture to suit working in low-light conditions. It also affords a great degree of control over depth-of-field for isolating subjects from the background and producing selective focus effects.
The new version III features a new optics design which offers a slightly more compact size and a better flare resistance. A carefully-designed 10 elements in 7 groups optics system with 1pc of HRI (High Refractive Index) & 5pcs of UD (Ultra-low dispersion) elements successfully minimizes the chromatic aberrations and delivers exceptional image quality.
An eleven-blade diaphragm helps to produce a softly diffused out-of-focus rendering (bokeh). The enclosure of the lens is made of metal to strengthen its durability.

Pricing & Availability
Mitakon Speedmaster 50mm f/0.95 III is now available to ship and purchase at ZY Optics official website (http://www.zyoptics.net/). The Recommended Retail price (before tax) is USD 799/pc.

Canon RF 50mm f/1.2L vs EF 50mm f/1.2L vs Sigma 50mm f/1.4 Art (RF 50mm reigns supreme)

Canon Rf 50mm

The folks at Mirrorless Comparisons compared the new Canon RF 50mm f/1.2L lens for the EOS R system with the Canon EF 50mm f/1.2L and Sigma 50mm f/1.4 Art lenses.

Needless to say it again, likely, but Canon made a highly regarded optical masterpiece with the RF 50mm f/1.2L. A lens that has a serious price but might even been underpriced for what it delivers.

It’ impressing to see how weak the EF 50mm f/1.2L performance is when compared to the RF 50mm f/1.2L (and also to the Sigma). The image below tells a long story about the optical performance of the RF 50mm f/1.2L. At f/1.8 the RF 50mm f/1.2L s already tack sharp.

From the reviewer’s conclusion:

[…] it should be quite clear which of the three 50mm primes reigns supreme. With its extraordinary sharpness across the frame at all apertures and beautiful bokeh, the new Canon RF 50mm 1.2 is the kind of lens for which portrait or wedding photographers would literally switch camera systems.

[…] A good example is the Sigma 50mm 1.4 Art, which is a third of the price of the RF lens. Although it is 1/3 of a stop slower and doesn’t offer quite the same level of edge-to-edge sharpness, it can still produce very satisfying results even at the fastest apertures.

Personally I believe the RF lens only makes sense if you feel you’ll get a significant “return” on the investment, be that the intangible satisfaction with the images you create (an emotional return) or the money you make as a result of professional work (a tangible financial return). Otherwise you might as well go with something less expensive and use your remaining budget to invest in additional equipment.

Mirrorless Comparison’s review comes with a lot of optical tests and sample photos, and you’ll see that the RF 50mm f/1.2L beats the other lenses in all tests. Except for the price. More information, reviews and more about the RF 50mm f/1.2L is listed here.
