Canon EF 400mm f/2.8L IS III and EF 600mm f/4L IS III Coming Around Photokina Show 2018




Canon is expected to announce a high end, full frame mirrorless camera soon, perhaps just before the 2018 Photokina Show since Nikon is also expected to announce their full frame mirrorless camera around the last week of August 2018 but they may also just make a development announcement and wait till Q1, 2019 to officially bring out their high end, full frame mirrorless body.

The EOS-90D and EOS-7D Mark III cameras may be announced in Q1 of 2019. In addition, a couple of Super Telephoto and one EF-M lenses are also expected, perhaps around the time of the 2018 Photokina Show in September in Germany as well.

My hope is one of the Big White lenses will be the EF 600mm f/4DO BR. Canon showcased this lens in their Expo back in September 2015 in New York City. Currently, the EF 400mm f/4 DO IS II is my favorite DO lens and accompanies me on all my wildlife photography tours but sometimes I can use a bit more focal length.

However, I suspect the Super Telephoto lenses to be announced will be the Series III version of the following : EF 400mm f/2.8L IS II and EF 600mm f/4L IS II. The EF 500mm f/4L IS II and EF 300mm f/2.8L IS II replacement will probably come in 2019. These lenses are already Very good and any meaningful improvement will be at best marginally. A weight reduction will be most welcome. Some of the Series II lenses reduced about 1 1/2 pound weight from their predecessors.

The mirrorless lens expected is probably the EF-M 32mm f/1.4 STM and will give the mirrorless line a fast lens for extra flexibility in different types of photography.

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 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 Cameras and Super Telephoto Lens in Football Games


Many people have seen Canon cameras and the ubiquitous white lens during football games. The Canon EOS-1D X camera and the Super Telephoto lens are generally very rugged and stand up to field use but not able to withstand a football player's crushing weight.

That is what happened during the Kansas City vs. Oklahoma game when the wide receiver fell on the camera combo while trying to make a catch at the back of the end zone. The player is fine but the equipment is severely damaged.
