A new patent from Canon details the optical formula for two new lenses that may very well fight it out to become the replacement for Canon’s mid-range 50mm lens.

Patent Publication No. 2015–172611, originally filed in March 2014, lays out the architecture for both a 50mm f/1.4 lens as well as a 58mm f/1.4 lens.

The former is made up of ten elements in eight groups, three of the elements being aspherical to minimize chromatic aberration.

The 58mm f/1.4 formula is comprised of twelve elements in nine groups, with three of the elements similarly being aspherical.

Three other lens formulas are mentioned in the text of the patent, including a 35mm f/1.4, 45mm f/1.4 and 60mm f/1.4. The 50mm and 58mm options prove to be the most interesting considering Canon’s mid-range 50mm lens is, without a doubt, due for an update.

Also interesting is the choice of a 58mm lens, considering Nikon’s success with its 58mm f/1.4 lens.

As with all patents, only time will tell if these will come to fruition. When they do, rest assured we’ll be the first to share the news with you.
