Canon EF 20-45mm f/2.8-4 lens is in development

Canon has patented a few lenses recently, including an EF 20-45mm f/2.8-4 wide-angle zoom as well as an EF-S 55-200mm f/4-6.3 telephoto zoom, that could be revealed at some point in the not-so-distant future.

Depending on who you ask, Canon might have or might not have lived up to the hype in 2015 when it comes to lens announcements. Either way, the company will keep on launching new optics in 2016 and, beside the known rumors, you can now add two more products to the list.

Sources in Japan have discovered patents for a some new optics, such as the EF 20-45mm f/2.8-4 for full-frame DSLRs and the EF-S 55-200mm f/4-6.3 for DSLRs with APS-C sensors.

All digital imaging companies are looking for new ways to improve their offer. Canon does not make an exception and, if you are using a full-frame EOS camera, then you may be able to get your hands on a 20-45mm f/2.8-4 lens soon.

The Japanese manufacturer has patented four optics in the same application. Three lenses are 16-35mm models, two of them having a maximum aperture of f/2.8 and the other one featuring a maximum aperture of f/4.

Finally, the fourth product is a Canon EF 20-45mm f/2.8-4 lens. It features 14 elements in 10 groups with multiple aspherical and Ultra Low Dispersion elements for improving image quality.

If it becomes a reality, then it will offer a minimum focusing distance of 28 centimeters and an inner focusing mechanism. It fits in the wide-angle zoom range and it does not have an integrated stabilization technology, while its maximum aperture means that it could be quite affordable.

Overall, it sounds good on paper and there is room for such new product on the market. In the past, Canon has sold 20-35mm f/2.8L and 20-35mm f/3.5-4.5 lens to the masses, but this version will have a longer focal length and a different diaphragm among others.

An EF-S 55-200mm f/4-6.3 STM lens has also been patented in Canon in Japan

The other patented lens that is worth mentioning is the weirder of the bunch. It has been patented separately and it consists of an EF-S 55-200mm f/4-6.3 STM optic.

The weirdness comes from the fact that Canon is already selling a similar, better, and affordable model: EF-S 55-250mm f/4-5.6 IS STM. This telephoto zoom optic has been around since 2013 and it is available at Amazon for about $300.

As stated above, the amount is reasonable considering its performance, so the news that a version with smaller focal length and slower aperture is in development comes as a surprise. Furthermore, this new unit does not even have a built-in image stabilization system.

Still, if it has been patented, then it has a chance of coming to the market. However, when it gets released, it will probably have a very small price tag. Stay close to Camyx to find out more details about it!
