Adorama has the Sigma 35mm f/1.4 DG HSM ART lens (Canon mount) on sale at $699. Compare at $899. Limited supply at this price. A great lens in our opinion.
Hi Lows Note spotted a rather interesting Canon patent application (2017-108266).
The patent literature describes a 90mm f/2.8L IS macro lens for the Canon EOS R system. Two optical formulas are discussed in the patent literature.
Specification and lens arrangement of embodiment 1
Focal length: 97.00mm
F number: 2.92
Half angle of view: 12.57
Image height: 21.64mm
Lens length: 115.12mm
Back focus: 20.01mm
Specification and lens arrangement of embodiment 3
Focal length: 86.00mm
F number: 2.87
Half angle of view: 14.12
Image height: 21.64mm
Lens length: 115.07mm
Back focus: 15.93mm
Well, this is a patent application for a lens that may indeed hit the market (most patent applications never become a real product).
More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production in the next few years are these:
Hi Lows Note spotted a Canon patent application (2018-197774) for an RF 28-70mm F/2-2.8 lens for the EOS R system.
Focal length: 28.68 – 67.90mm
F number: 2.26 – 2.91
Half angle of view: 37.03 – 17.67
Image height: 21.64 – 21.64mm
Lens length: 149.69 – 174.43mm
Back focus: 20.57 – 35.45mm
The interesting fact: the lens literature does not refer to an image stabilisation group inside the lens. Some people is saying this is a sign for IBIS (In Body Image Stabilisation) coming to future EOS R models (rumors already surfaced). We are not sure how to interpret this.
Canon always stated the superiority of image stabilisation in the lens. Never the less, Canon execs didn’t exclude the possibility of a future mirrorless camera with IBIS, and there are a few patents clearly discussing IBIS (patent 1 | 2 | 3).
Do you think this patent application is a clear sign of IBIS to be featured on future EOS R cameras?
Canon in an unusual move for the company already disclosed the the EOS R lens roadmap for the next years (also see this interview). The lens described in the patent application doesn’t seem to be on Canon’s immediate agenda. Keep in mind that patents are a way for companies to secure they research and development and hence their intellectual propriety. A patent application rarely means a product is coming to the market soon.

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.
[…] 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.
