Canon Patent - EF 600mm f/4 DO IS Lens

Canon EF 600mm f/4 DO BR lens

Canon is working on improving their Super Telephoto lens line with the aim of increasing image quality, focal length and decreasing weight. Their EF 400mm f/4 DO IS II is a fine example of this. I purchased the Series I model over 10 years ago but the Series II is a dramatic improvement and I expect more Diffractive Optics models will be announce in the years ahead.

The EF 600mm f/4 DO BR lens made an appearance in last year's Canon EXPO in New York City. This lens will be announced some time next year, in time for the 2018 Winter Olympics in South Korea. I am anxious to buy this lens. The patent for the Canon EF 600mm f/4 DO IS is listed below.

Canon EF 85mm f/1.4L IS Lens Coming in 2017

Canon is expected to announce quite a few new lenses in 2017. Among them are the EF 200-600mm f/4.5-5.6 Super Zoom, EF 600mm f/4 DO BR and EF 70-200mm f/2.8L IS III.

Now you can add another to this list - EF 85mm f/1.4L IS. Although this new glass is slightly 'slower' than the current EF 85mm f/.12L II lens, if I were a betting person, I'd say this will be a replacement for the current model. The present EF 85mm Series II lens was announced back in 2006. The new lens will have a 4 stop IS compensation, the latest Air Sphere and Fluorine coatings plus a much improved USM AF system.

In addition, Canon has another Super Telephoto lens with built-in extenders patented - EF 400mm f/2.8L IS 1.4x + 1.7x Extender USM. You can see how Canon manufactures its EF and Super Telephoto lenses by clicking on their video links.

Of course, with estimated product delivery timetables, nothing is set in stone. Delays and changes in production plans may alter the announcement dates but it's safe to say, 2017 will be an exciting year for new lens introduction. You can see my equipment bag and works on MichaelDanielHo.com

New Canon Patent - EF 300mm f/2.8L IS Lens

Canon EF 300mm f/2.8L IS II lens

A new patent for the Canon EF 300mm f/2.8L IS lens has been uncovered. This may be the beginning of the Series III version of this venerable lens.

I reported recently Canon is reworking the entire line of their Super Telephoto lens with the approaching 2020 Summer Olympics Games in Tokyo in mind. The current EF 300mm f/2.8L IS II is one of the sharpest lens around and a favorite of mine for wildlife photography. You can see my equipment bag and works on MichaelDanielHo.com

Canon EF 200-600mm f/4.5-5.6 IS Super Zoom Lens Coming

Late in 2015, I reported Canon has filed a patent for a Super Zoom EF 200-600mm f/4.5-5.6 IS lens and is scheduled to release the lens some time in 2017. The EOS-6D Mark II full frame camera is expected to be announced some time in Q1, perhaps before the CP+ Show in Yokohama, Japan.

There is a chance the EF 200-600mm lens may accompany the EOS-6D Mark II during the announcement. My readers know I am not impressed by the Super Zoom models from Sigma and Tamron in the form of a 150-600mm lens. The new Canon lens will not be a 'L' model. That means it will be priced slightly higher than the third parties lens and most probably not weather and dust sealed.

I may be interested in this new lens depending on the built quality but the one Super Telephoto lens I am most interested in is the EF 600mm f/4 DO BR, expected to debut some time next year as well. Keep checking back for the latest info as I receive them.
