Canon Set To Announce 300mm Lens For EOS R With New And Unique Feature?

Canon Eos R

After the rumor about a 500mm telephoto lens for the Canon EOS R full frame mirrorless system, a 300mm lens rumor surfaced from the web.

It’s suggested Canon might announce a 300mm f/2.8L IS lens for the EOS R system along with the above mentioned 500mm lens. The announcement is expected somewhen in 2020. This 300mm f/2.8 IS lens for EOS R is said to sport a “new and unique feature for super telephoto lenses”. No hints what the feature is about. Both lenses could be announced along with the rumored EOS-1D X equivalent EOS R model.

It seems 2020 will be an important year for the EOS R ecosystem with lots of lenses that are said to be announced. In the meantime we are still waiting for Canon to release some RF mount lenses they have already announced (development).

All Canon rumors are listed here.

Lens Maker Irix Reaches For The Stars, Literally

Irix

Lens manufacturer Irix announced the Irix 300 SR, a lens ready for outer space.

Press release:

Young photographic company Irix is reaching infinity…literally.

Irix, young company which successfully entered photography world just few years ago with innovative and properly designed products is reaching another level of evolution. Quality, durability and precision were always strong points of Irix. It has been just proven. Irix has been selected as cooperating company in exciting, high technology project.

Irix Team is proud to announce its participation in the project of the first Polish Earth observation satellite named Światowid. Nanosatellite equipped with the test platform of future Irix 300SR lens, on April 17, 2019, will be elevated to Earth’s orbit.

The collaboration between the manufacturer of Irix lenses and SatRevolution company began in mid 2017. The result of this collaboration is the first prototype of the Irix 300 SR experimental lens, which, combined with the camera installed in the Światowid nanosatellite, will provide the best possible quality of Earth’s images from space.

Irix 300 SR – the first Space Ready Irix lens

The technical requirements for the lens design were a real challenge for the Irix R&D department, as they included strictly defined optical parameters such as: focal length, f-number, optical resolution and very low level of optical aberrations. The design of the lens has to be also modular in order to provide the possibility of use with satellites equipped with cameras of a different resolution and specific diagonal size of the sensor. Such an optical system has to fit designed place for optical system in satellite’s construction. Maximum diameter, but what is more important in case of nanosatellites weight must be strictly controlled. (Światowid’s optical system limit is 300 grams / 0.66 lbs).

Very important for the success of the satellite’s mission are launching standards. Launching into orbit and working in open space is a complicated process. Extremely high standards of materials and technologies used must be fulfilled. The same requirements were applied to the Irix 300SR lens. Design and construction process must follow NASA guidelines for materials and technologies permitted for space flight. In other words, the Irix 300SR has to meet requirements much higher than lenses used on a daily basis by astronauts photographing from the board of the International Space Station.

Today’s launch is a first step in research project supported by EU funds (Polish National Centre for Research and Development). Irix R&D center in Poland for next several months will be preparing lens for next launch. Except optical performance which will be on highest level individual components of the lens as well as the complete lens will have to pass various tests. Among other things resistance to overload as well as mechanical and acoustic vibrations occurring during the launch of the rocket will be tested. The aging tests will verify the lens’ resistance to a wide temperature range of -50°C to 150° (-58°F to 302°F), UV radiation and extreme vacuum conditions.

Knowledge and technologies of this project will be used in other lenses and products intended for the “civil” photographic market. In other words, Irix product will become even better and more innovative.

Ready for the mission

The satellite Światowid with the test platform of future Irix 300SR lens onboard will be delivered to the International Space Station via the NanoRacks operator as part of the Cygnus NG-11 Commercial Resupply Service. The launch of Antares 230 rocket is planned for April 17, 2019 at 4:46 PM EDT (20:46 UTC) from NASA’s Wallops Flight Facility in Wallops, Virginia (US).

Irix Team cordially invites you to visit the special website dedicated to Irix 300SR lens available at https://space.irixlens.com

We also invite you to visit the SatRevolution website at www.satrevolution.com, where you will find more details about the Światowid satellite project.


Here Are All The New Samyang Lenses (35mm f/1.4 AE for Canon inclusive)

Here are all the lenses Samyang officially announced today. And yes, they released the 35mm f/1.4 AE lens for Canon mount (spec sheet here) – Samyang’s first lens with electronic contacts for Canon (if I am not wrong).

Samyang press release:

Samyang company announces expansion of its sales portfolio and market release of new photographic and cine lenses. New Samyang 35mm f/1.4 Canon AE, 300mm f/6.3 Mirror DSLR photo lenses and VDSLR series is to be released on April 29th 2014. Samyang 10mm T3.1, 12mm T2.2 and 7.5mm T3.8.

New products branded with Samyang logotype include an interesting 35mm f/1.4 lens with Canon EF mount, the latest version will feature AE (Auto Exposure) function, which was fitted only in lenses with Nikon F mount before. The newest version of the lens that is marked with AE symbol comes with a microprocessor which can electronically confirm the focus value from the body level. The lens’s construction remained unchanged and still ensures a perfect optical and mechanical quality. Samyang 35mm f/1.4 has been designed to work with Canon digital reflex cameras equipped with full-frame and APS-C sensors.

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] Is Canon’s High Resolution (46MP) DSLR Around The Corner? (and three new lenses too?)

CR has more hints that Canon will soon announce a new, high resolution DSLR. The talk is about a 46MP sensor.

I’m told that the coming big megapixel camera is a very new sensor design/overhaul. The emphasis is in the dynamic range of the sensor. Performance is said to be on the level of medium format, even better than the impressive D800.

The high res cam is said to get a new naming scheme (no 3D nor something with “D”). Canon should announce it at PhotoPlus in New York City in October.

There are also new lenses that are said to show up soon. The EF 200-400 f/4L IS 1.4x is expected to be announced by Canon at PhotoPlus. Finally, two f/4 telephoto lenses are rumored to be announced in January 2013: the EF 300 f/4L IS II and the EF 400 f/4L IS.
