Canon is clearly working on new ultra wide zoom lenses to add to the lineup, we have <a href="http://www.canonrumors.com/patent-canon-ef-17-35mm-f-4-5-6-is-stm/">yesterdays patent showing a EF 17-35mm f/4-5.6 IS STM</a> and today we see a patent application that covers 6 different ultra wide angle zoom optical formulas for APS-C sensors.</p>
<p><strong>Optical Formulas in Japan patent application: 2017-207649 </strong></p>


<ul>
<li>14-35mm f/2.8</li>
<li>9-22mm f/2.8</li>
<li>10-35mm f/2.8-3.5</li>
<li>18-80mm f/4.0</li>
<li>18-75mm  f/4.0</li>
<li>12-30mm f/2.8</li>
</ul>
<p>This patent application may pertain to development of lenses that have already been released, or they could be part of future lens designs.</p>

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

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)
