Canon patent for EF 24-300mm f/3.5-5.6 lens for full-frame DSLR

24-300mm f/3.5-5.6

Canon patent for a EF 24-300mm f/3.5-5.6 USM lens for full-frame sensors. The patent description doesn’t mention image stabilisation (IS), so it’s unlikely this will be the replacement for the Canon EF 28-300mm f/3.5-5.6L IS (announced 2001).

As usual, a filed patent doesn’t mean the described gear will necessarily hit the market. On the other hand, this may just be a patent on the way to the replacement for the 28-300mm f/3.5-5.6, and we could soon see another patent for a similar optical formula and with added IS.

Canon Patent for CN-E 70-200mm f/2.8 Lens (super 35mm, Cinema EOS)

CN-E 70-200mm f/2.8

Canon filed a patent for a CN-E 70-200mm f/2.8 Cinema lens for super 35mm sensors, i.e. for Canon’s Cinema EOS products. If this patent hits the market it will be a T2.8 lens. However, a patent does not necessarily mean such a lens will hit the market any time soon. New Canon Cinema EOS products are expected for NAB 2016.

Canon patent for EF 16-40mm f/4 lens (replacement for EF 17-40mm f/4?)

canon patent

Canon filed a patent for an EF 16-40mm f/4 lens, which appears to point to a replacement for the venerable Canon EF 17-40mm f/4L USM, one of the more affordable Canon “L” lenses. The EF 17-40mm f/4L was introduced in 2003, a replacement is likely given the new high resolution sensors Canon is starting to produce.

Canon patent for EF-M 55mm f/3.5 macro lens

canon patent

A Canon patent for an EF-M 55mm f/3.5 macro lens for the EOS M system.

Canon is working on the future of the EOS M system, and there is a lot to come in 2016. This patent is just a hint about Canon’s mirrorless plans. This is a patent for an APS-C sensor, so the rumored Canon full-frame mirrorless camera is not involved here. However, we spotted a Canon patent for a similar optical formula some time ago (50mm f/3.5 IS). According to my sources, Canon’s full-frame mirrorless camera has been delayed because of mount-related issues. Another rumor we got, states that early prototypes of such a camera are already undergoing lab tests. Hard to say when we really can expect this camera, but I am sure it is coming.

Canon is now taking their EOS M system seriously. The EOS M3 was the right step in the right direction, and is a great camera. Some clickbait sites are saying that the EOS M3 is one of Canon’s worse releases of 2015. That’s utterly dumb and likely the oddest statement about Canon in 2015, and has the sole purpose to get traffic by smashing Canon. I have to say that I am surprised to see how many people feels the urge to smash the Canon EOS M3, as they did before with the EOS M. Guess this is just childish, and profitable. I own both cameras, along  with APS-C and FF bodies. Well, I am now on travel for the next 2 months and guess what camera I have with me? Right, the EOS M3. A great mirrorless camera with an image quality that outperforms most of the competitors.

Canon patent for 200-600mm f/4.5-5.6 superzoom for full-frame DSLRs

 

Canon patent
200-600mm f/4.5-5.6

Canon patent for a superzoom lens for full-frame DSLRs, an EF 200-600mm f/4.5-5.6 lens.

As always with patents, you can’t be sure if the described product will hit the market. However, the optical formula in the patent reminds the Sigma 150-600mm F5-6.3 DG OS HSM lens, and given how well the latest Sigma lenses perform (given the price), I wouldn’t be suprised if Canon decides to strike back. I think such a lens would be welcome by the community.
