Patent: More Ultra Wide Zoom Lens Patents
« on: December 27, 2017, 02:02:07 PM »
Canon is clearly working on new ultra wide zoom lenses to add to the lineup, we have yesterdays patent showing a EF 17-35mm f/4-5.6 IS STM and today we see a patent application that covers 6 different ultra wide angle zoom optical formulas for APS-C sensors.

Optical Formulas in Japan patent application: 2017-207649 

  • 14-35mm f/2.8
  • 9-22mm f/2.8
  • 10-35mm f/2.8-3.5
  • 18-80mm f/4.0
  • 18-75mm  f/4.0
  • 12-30mm f/2.8

This patent application may pertain to development of lenses that have already been released, or they could be part of future lens designs.

Read the full breakdown of the patent application here.

Some interesting lenses.
Sure there is market for 18-80mm F4, but hardly we will see a 9-22mm F2.8.

I thought so too.
Canon needs some constant aperture lenses, but low cost for video.

Hmm... constant-aperture APS-C zooms... yeah, zero chance that anything comes of these patents  :o ::)

Seriously, a 9-22mm f/2.8, if optically any good at all, would definitely be a disruptive, unprecedented lens in the APS-C world.

18mm is not wide enough for a high-end standard zoom on crop cameras.
And until now, Canon has shown zero interest in providing fast UWAs in EF-S format.

So, I say that these will be (expensive) cine lenses for super-35mm cine cameras.

There is always the very good EF-S15-85 lens.

And the EF-S10-22/3.5-4.5 is fast enough on the wide part.

I find all these lenses interesting. Especially the 10-35mm f/2.8-3.5 seems to me a very practical one (16-56 equivalent and fast).

For me the 14-35mm f/2.8 could be very interesting for use with my EOS M5. Sometimes I miss the 18-55 which I sold together with my EOS M.
I do have the 40mm f/2.8 pancake and the EF-M 22mm together with other EF-M stuff. This 14-35mm would cover the gap between 22 and 40mm quite well.
If I want to go the prime route I could by the EF-M 28 Macro and/or the EF-S 35mm f/2.8 Macro.

But the zoom would be more convinient for light travel purposes.

FWIW, Canon's 10-18mm f4.5-5.6 IS EF-S lens puts in a good showing for the money. (roughly 16mm - 29mm FF equivalence)
The worst picture ever is the one not taken: so shoot, shoot, shoot! Know your equipment first however to avoid as much as possible, bad photos. ;-)
