Patent: Sigma 12mm f/2.8 optical formula

Patent: Sigma 12mm f/2.8 optical formula

By Canon Rumors | December 1, 2018 | Canon Patents

It looks like Sigma is continuing to work on wide angle lenses for full frame cameras. A recent patent application shows an optical formula for a 12mm f/2.8 Art series lens for full frame cameras.

Sigma 12mm f/2.8 Art Specifications:

  • Focal length: 12.42mm
  • F number: 2.93
  • Angle of view: 120.49
  • Image height: 21.63mm
  • Lens length: 169.4mm

Sigma doesn’t have any fear of making lenses with similar focal lengths and speeds, so it wouldn’t surprise me to see this patent actually become a product in the near future.

Patent: Canon speedbooster for EOS M

Patent: Canon speedbooster for EOS M

By Canon Rumors | November 30, 2018 | Canon Patents

It looks like Canon is developing its own speedbooster for EF lenses on the EF-M mount.

Canon News uncovered a patent last week that showed Canon was looking at a new EOS M adapter, and again this week, a new patent showing the concept in more detail has emerged.

Japan Patent Application 2018-189864:

This patent application is for a converter that takes EF lenses and reduces the focal length and decreases the aperture all at once.

The example in this patent applications shows a 50mm f/1.4 lens (full frame) with a back focus of 39.80 (EF full frame) and converts the lens to a 40mm f/1.2 with an image height of 13.66 and an 18mm back focus, which would work for EOS M cameras.

If Canon is indeed going to keep the EOS M line around, developing a speedbooster for the system would be quite a nice addition to the lineup.

Patent: 400mm f/2.8 DO and 300 f/2.8 DO

Patent: 400mm f/2.8 DO and 300 f/2.8 DO

By Canon Rumors | November 29, 2018 | Canon Patents

The diffractive optics related patents continue to appear from Canon. This time we get a patent that covers both a 300mm f/2.8 DO and a 400mm f/2.8 DO.

We think a slew of diffractive optics super telephotos are on the way for the RF mount and these two optical formulas may find their way to the RF mount in 2020. Perhaps alongside an EOS R version of the EOS-1D X Mark II.

As Canon News points out, the back focus on a super telephoto lens is quite large, so these could easily be RF mount lenses.

Review: Laowa 24mm f/14 Relay Macro

Review: Laowa 24mm f/14 Relay Macro

By Canon Rumors | November 27, 2018 | Canon Reviews

Keith over at Northlight Images has completed his exhaustive review of the strange Laowa 24mm f/14 relay macro lens. While a relay lens isn’t a new concept, Laowa’s relatively inexpensive version is.

The number of people that need a lens like this is likely quite small, but the really creative photography types may come up with some really cool uses for the lens.

From Northlight:

Quite the most unusual lens I’ve tried out. Relay lenses have been around for a while but at typically 10 times the cost of the Laowa. The lens is a challenge to use – not technically (it’s excellent), but in expanding your creative vision to see what it could let you achieve.

It’s solidly built with very smooth focus and aperture controls. The focus throw (~160º) is enough to make manual focus stacking very easy. Read the full review

Canon EOS R body with more than 75mp on the horizon [CR2]

By Canon Rumors | November 25, 2018 | Canon DSLR Rumors

We’ve speculated recently that Canon will not be releasing next iterations for the EOS 5DS and EOS 5DS R, and instead will move the high megapixel cameras to the EOS R line.

A few more people have told us that this will indeed be the case and that an EOS R camera with slightly more than 75mp is in development. This camera could appear sometime in the 2nd half of 2019 we’re told. Though an exact announcement date is a long way from being decided.

One source added that the high megapixel EOS R will come once 4 or 5 more native RF mount lenses are announced, with one of the new lenses being “the best landscape lens in the Canon lineup”.

There are no more imaging announcements in 2018, but early 2019 should see the PowerShot and EOS DSLR lineup getting new additions, and a bit later another EOS R camera body, though the next EOS R body is expected to be “entry level”.

Patent: Canon EF-M 10mm f/2.8 Fisheye

Patent: Canon EF-M 10mm f/2.8 Fisheye

By Canon Rumors | November 22, 2018 | Canon Patents

Japan Patent Application 2018185386 showcases an optical formula for an EF-M 10mm f/2.8 Fisheye lens. The short backfocus distance tells us it’s for a mirrorless application, and we’re pretty sure there will NOT be dedicated APS-C lenses for the EOS R system.

Is a fisheye needed for the EOS M lineup? Probably not, but if priced right, it could be a solid niche lens for the system.

Samyang to announce XP 35mm f/1.2 soon

Samyang to announce XP 35mm f/1.2 soon

By Canon Rumors | November 21, 2018 | Third Party Lenses

It looks like Samyang is going to announce another very fast prime lens, this time in the form of an XP 35mm f/1.2.

The XP line of lenses from Samyang are manual focus, but they’re also considered the brands premium line.

Currently, the XP series from Samyang consists of the following lenses:

  • XP 14mm f/2.4
  • XP 50mm f/1.2
  • XP 85mm f/1.2

The exact announcement date for the XP 35mm f/1.2 is unknown, but expect it some time in the next week or two.

The upcoming RF mount wide angle f/2.8L zoom will be wider than 16mm [CR2]

The upcoming RF mount wide angle f/2.8L zoom will be wider than 16mm [CR2]

By Canon Rumors | November 20, 2018 | Canon Lens Rumors

Canon has already mentioned that a trio of f/2.8L zoom lenses is coming in 2019 for the RF mount. It’s pretty obvious that we should expect some kind of “holy trinity” of lenses such as an RF 16-35mm f/2.8L. RF 24-70mm f/2.8L IS and an RF 70-200mm f/2.8L IS.

We’re being told that the wide angle lens for the RF “holy trinity” will be wider than 16mm. Both an RF 12-35mm f/2.8L and an RF 14-35mm f/2.8L have been developed for testing.
