Canon Patent Application for 800mm f/5.6 lens

Canon Patent Application

A Canon patent application (2018-087965) for what might be the future replacement for the Canon EF 800mm f/5.6L IS lens.

The patent literature describes a lens concept where weight and size are reduced without affecting optical performance or causing increased chromatic aberrations.

Machine translated patent literature excerpt:

The method of using for a part of imaging optical system the diffracted-light faculty which has a diffraction working effect as a method of reducing lens weight is known correcting satisfactorily several aberration including the chromatic aberration of the imaging optical system. The imaging optical system which constituted the front lens group from ** material whose refractive index is higher than a low dispersing material with abnormal portion dispersibility, such as fluorite, and attained size and weight reduction of the whole system is known, using a diffraction working effect and reducing the lens number of sheets of the front lens group which was conventionally required for aberration compensation

There is a lot of buzz around Canon patent applications as of lately, and a lot of misunderstanding too. Bear in mind that a patent application does not mean a company will launch a product anytime soon. A patent application is a way companies have to secure their research and their intellectual property. In this sense, nothing here is a guarantee that the EF 800mm f/5.6L lens will be replaced in the close future.

Some Canon patent applications we think might get into production in the next few years are these:

More Sigma “Sport” Lenses Coming in 2014

Sigma "Sport" Lenses

Sigma 18-35mm f/1.8 DC HSM
B&H Photo, Adorama, Amazon USA, Amazon Canada, Canon Canada, Canon USA

It appears that Sigma will enjoy us with more lenses based on their new technology. Various lenses that will be part of the “Sport” line-up may be announced. The rumor fits with the rumored list of next Sigma lenses we posted aome time ago.

The rumor has word that Sigma will announce first a 300mm f/2.8 OS and a 400mm f/2.8 OS lens. These lenses may be undergone field-testing during the Winter Olympic Games. The other lenses Sigma is said to work on are a 500mm and a 800mm lens.

I can just hope Sigma will again be able to pack all the engineering wizardry they put into the awesome 18-35mm f/1.8 DC HSM and 35mm f1.4 DG lenses.

Rumor: New Canon EF 800mm f/5.6L IS II Lens Could Be Announced Fall 2013

EF 800mm f/5.6L IS II

A rumor concerning the replacement of the replacement of the Canon EF 800mm f/5.6L IS USM (price & specs) lens.

The Canon EF 800mm f/5.6L IS II could be announced shortly after the Canon EF 200-400 f/4L IS 1.4x has (eventually) started shipping. According to the latest rumors this could due in Fall 2013. However, if there will be an announcement it will be a development announcement. Regarding used materials the new EF 800mm f/5.6L IS II will have a new build type, the optical formula is said to be “nearly identical” but improvements in vignetting and sharpness are possible.

Finally, some sources say the EF 800mm f/5.6L IS II could have a built-in teleconverter.

This will not be a cheap lens: the actual Canon EF 800mm f/5.6L IS USM has a price tag of $13,249.

Canon Set To Release An EF 800 f/5.6L IS II Lens In 2013?

Canon Rumors has been told that Canon could release a new 800mm in 2013. The EF 800 f/5.6L IS II lens could have a newly developed 6 stops image stabilization system. The weight is said to be less than the EF 600 f/4L IS II

Moreover, there are rumors about new supertelephoto zooms and 400mm primes. No timetable or schedule was suggested.

Finally the 1.4 teleconverter sported on the EF 200-400 f/4L IS 1.4x is said to get featured on more lenses in the future, at least the technology appears to be tested on other lenses.

Rumor: New Canon Lenses Around The Corner?

New Canon lenses rumor tidbits. Canon Rumors got another confirmation that a Canon EF 800 f/5.6L IS II lens is out there getting tested. It is not ready for the market and it is suggested that Canon will not announce it before Nikon announced its own 800mm lens. Another lens was mentioned, the EF 200 f/2L IS, also said to be far from being announced. Finally, one of CR’s sources says that he or she tested an ultra-wide zoom on an EOS-1D Xs (which, supposedly, is the big megapixel DSLR rumors say Canon is working on).

But the Canon lens rumor-mill is also yielding some tidbits about an EF 135mm f/2L replacement. The talk is about an EF 135mm f/2L prototype with image stabilization. Replacement of the current EF 135mm may be around the corner.

It appears as if there are definitely coming new lenses before the end of 2012, some NDAs (non disclosure agreement) should be over by the end of the month.
