Canon EOS R6 Still Expected To Get Announced in May 2020

Canon Eos R6 Rumor

Latest rumors have it that Canon will announced the Canon EOS R6 in May 2020, as we were expecting.

However, there might be some issues with availability after the announcement, because of the global pandemic situation. The Canon EOS R5 is also expected to get released in May 2020, and here too there might be issues with availability. Availability depends by demand but at least for the EOS R5 it’s safe to say it will sell a lot. A few days ago Canon revealed some more specifications.

The EOS R6 will be less feature rich as the R5. If the EOS R5 is the mirrorless version of a 5-series camera then the EOS R6 is the mirrorless version of the 6-series cameras.

Rumored Canon EOS R6 Specifications:

  • 20mp full-frame CMOS sensor
  • IBIS
  • 12fps mechanical and 20fps electronic.
  • 4K @ 60p
  • FullHD @ 120p
  • Dual card slots
  • No top-down screen
  • Lower resolution EVF than the EOS R5
  • Build quality not as good as the EOS R5
  • New battery (Not sure if it’s the same as the EOS R5)
  • June 2020 launch

All Canon EOS R6 rumors are listed here.

Stay safe.

Canon Reveals More Specs Of Upcoming EOS R5 (+ first impression video)

Canon EOS R5

EDIT: It appears a lot of (lucky) people managed to get their hands on the Canon EOS R5. We added three more hands-on videos below.


During today’s live-streamed press conference, Canon unveiled more specifications about the highly anticipated yet unreleased Canon EOS R5.

It seems 45MP resolution are indirectly confirmed through the revealed specifications. Canon says the R5 will shoot DCI 8192 x 4320. That means the sensor has a width of 8192 pixels. Given the 3:2 ratio the height is 5461 pixels. All sums up to a 44.7MP sensor.

This is the second teaser after the development announcement and a subsequent reveal of more specifications. All R5 coverage is listed here.

Laowa 100mm f/2.8 2X Ultra Macro APO Now Available For the Canon EOS R

Laowa 100mm F/2.8 2X Ultra Macro APO

Venus Optics has released the Laowa 100mm f/2.8 2X Ultra Macro APO lens for the Canon RF and Nikon Z mounts.

At a glance:

  • 2:1 Magnification at same physical size – All of the 100mm macro lenses in the market can only reproduce 1:1 magnificati on (life-size) image only. The extended 2x magnification means more details ca n be seen through the lens. Photographers can now take advantage of the wider magnification range to capture bugs at different sizes.
  • Apochromat APO design (invisible CA)- The Laowa 100mm f/2.8 has a Apochromat (APO) design where the chromatic aberration (CA) at BOTH in-focus & out-of-focus area is controlled to the minimal. CA has long been one of the most annoying aberrations for macro photography and now you can forget about this and focus more on taking a great shot.
  • Similar size as 1:1 macro lens – Despite the extended magnification range, the size of our Laowa 100mm is actually comparable to other macro lenses in the market.
  • Outstanding Sharpness
  • Smooth Bokeh rendering
  • Outstanding Portrait lens with crystal sharpness – Laowa 100mm f/2.8 2:1 Ultra Macro APO is not only a exceptionally macro lens. It can also focus to infinity and is a very decent telephoto portrait lens.

The new Laowa 100mm Macro is now available at major retailers at $449: Amazon USA, Amazon CA, B&H Photo, Adorama, Digitalrev, KEH Camera, eBay US, Canon USA, Canon CA, BestBuy
