Canon Powershot Patent - 3.6-255mm f/2.8-7 Lens with Built-in Extender

Egami discovered another new Canon patent for PowerShot cameras. It is a 3.6-255mm f/2.8-7 lens with a built-in extender, effectively giving it a 35mm equivalent of about 2000mm @ f/10.

The Canon Powershot SX70 HS is expected to be announced very soon. This patent is most probably related to the same type of technology which enables the camera to have a 100x zoom capability.

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.

Canon Patent - EF 28-560mm f/2.8-5.6L IS Super Zoom Lens

Egami has uncovered a Canon patent for a super zoom lens, the EF 28-560mm f/2.8-5.6. I have reported earlier about Canon's plan on releasing the EF 200-600mm lens some time in 2017. This new glass will be a nice addition or replacement to the current EF 28-300mm f/3.5-5.6L IS super zoom, which is one of my favorite glass for wildlife photography. If Canon does decided to release this lens, it will be rather large and heavy because the current EF 28-300mm glass already weighs almost 3.7 pounds. You can see my equipment bag and see my works on MichaelDanielHo.com

In July, I reported Canon filed a 'crazy' patent for a EF 40-800mm f/4.5-5.6 lens. A patent is just that, a claim on some intellectual property. It is a long way from being a prototype, let alone a marketable product.

Canon Patent - EF 40-800mm f/4.5-5.6 Super Zoom Lens

Egami has uncovered another Canon patent. This time it's the EF 40-800mm f/4.5-5.6 lens. Frankly, I think this is just a project for some engineers with too much time on their hands. A patent is far from being a prototype, let alone a production model lens.

Currently, the Canon EF 28-300mm f/3.5-5.6L IS is my favorite Super Zoom lens in their lineup. It affords me a wide focal length to choose from when it is impractical or impossible to change lens in the middle of a shoot. The drawback is the weight, Can you imagine the weight of a 40-800mm lens?

I think the chances of this lens coming to market in its present form is zero to none, although Canon is expected to announce a Super Zoom lens sometime in 2017. This type of focal length is very popular and Nikon, Sigma and Tamron all have their models on the market now.

At the present time, I am in Alaska on my annual wildlife photography shoot and was informed by my sources Canon will be adding a brand new feature to the upcoming EOS-5D Mark IV camera. They are playing their cards very close to their chest and not revealing much except to generate maximum publicity and excitement for the launch next month.

Tamron Patent - 100-400mm f/4.5-6.3 VC Lens

Tamron 150-600mm f/5-6.3 Di VC USD lens

Egami has uncovered a patent from Tamron for a 100-400mm f/4.5-6.3 VC lens. This is the most popular, medium focal length, zoom lens for wildlife photography and my personal favorite is the Canon EF 100-400mm f/4.5-5.6L IS II. I have taken this lens on worldwide photo shoots. You can see my equipment bag and works on MichaelDanielHo.com.

Tamron is a third party lens manufacturer and super long zoom lens is very popular. Canon is expected to announce their own Super Zoom lens some time n 2017.

Canon Patent - EF 28-560mm f/2.8-5.6 Lens

Canon EF 28-300mm f/3.5-5.6L IS Lens

I have just returned from my Upper Amazon/Peruvian Highlands Photo Tour testing the Canon EOS-1D X Mark II camera in hot, steamy jungles and cold, two miles plus high, Andean mountains. Overall, I am quite impressed by the new body but now I have to take some time to get back to the daily routine, process the photos and get ready for my next trip to again test the camera in a whole new part of the world and environment.

Getting back to my readers on photography news, Egami has uncovered a new Canon patent for another super zoom lens, the EF 28-560mm f/2.8-5.6. I have reported earlier about Canon's plan on releasing the EF 200-600mm lens some time in 2017.

Sigma Patent - 120-600mm f/5-6.3 Super Zoom Lens

Sigma 200-500mm f/2.8 EX DG APO lens 

It appears Super Zoom is the new rage for zoom lens going into 2016. Egami, the Japanese photography blog has uncovered a Sigma patent for a 120-600mm f/5-6.3 lens.

Sigma and Tamron already has a 150-600mm f/5-6.3 and shorter super zoom lenses on the market and Nikon has their 200-500mm f/5.6 ED VR lens. Canon has recently patented the EF 200-600mm f/4.5-5.6L IS and EF 24-300mm f/3.5-5.6 lens.

It all started with the Canon EF 28-300mm f/3.5-5.6L IS Super Zoom lens back in 2004. This is my favorite professional grade 'L' super zoom lens for wildlife photography when it is not practical to change lens in the middle of a photo shoot. However, the lens is aging and can benefit from an upgrade. Since the introduction of the unrivaled EF 200-400mm f/4L IS USM Extender 1.4x lens back in 2013, there is room for a longer focal length Super Zoom lens in the EF lineup.

Canon Patent - 24-300mm f/3.5-5.6 Super Zoom Lens

Canon EF 28-300mm f/3.5-5.6L IS Super zoom lens

The Japanese Photography blog, Egami has uncovered a new Canon patent for a full frame, 24-300mm f/3.5-5.6 superzoom lens. In December of 2015, another Canon patent for the EF 200-600mm f/4.5-5.6 IS zoom lens was discovered.

There are other Super zoom lens from Sigma and Tamron but they are quite professional grade. The current Canon EF 28-300mm f/3.5-5.6L IS is my favorite all-in-one zoom for wildlife photography when it is not feasible to change lens in the middle of a shoot. However, it was released in 2004 and has an older version of IS.

A new Canon Super zoom lens can certainly benefit from advancement in coatings, optics and Image Stabilization. I will be interested in acquiring both the 24-300mm and 200-600mm zoom lens if they come out in the 'L' model. There is a better than even chance Canon will announce another Super zoom some time in 2016.
