[Canon Rumors]

The EOS M patents continue to flood in, this time we get a patent for an EF-M 15-50mm f/3.5-5.6 IS STM optical formula.</p>
<p><strong>Patent Publication No. 2016-75742 (Google translated)</strong></p>
<ul>
<li>Published 2016.5.12</li>
<li>Filing date 2014.10.3</li>
<li>Zoom ratio 2.94</li>

With the number of patents for EF-M lenses Canon could well be releasing a DSLR type M camera by year end!

Quite similar to the existing EF-M 15-45mm f/3.5-6.3 IS STM lens...not sure we'll see this one produced.

 

[Wizardly]

Typo in the headline. Widest focal length in the 4 examples is 16mm, not 15mm. 18-55mm is one of the WE.

 

[Etienne]

I sure would like a EF-M 15mm f/2 prime

 

[eninja]

I sure would like a EF-M 15mm f/2 prime

+2 as long as its pancake,
+1 any 15mm to 18mm

Mount the EF-M 22mm f/2. Take three steps back. Done.

Seriously, though...15-18mm puts it into retrofocal design territory, it won't be a pancake, it will be bigger and heavier, and more expensive. I doubt such a lens is high on Canon's list of priorities.

More STM glass for a stunted growth mirrorless system that lacks an integral viewfinder? Yep, that's the ticket. :

The canyon-sized firewall Canon maintains between EOS-M and the SLRs is laughable. EOS-M takes fine images, don't get me wrong, but sheesh -- give its users something to get excited about, Canon. How about a USM / Nano USM lens? A body with a viewfinder? Dare we dream so bravely?

I appreciate the recent macro offering, in fairness, but I feel like it's brand stuck in second gear.

I just bought a used m1 on ebay so I could get the new macro lens. Never owned an m camera before, but that lens got me excited. As it is now, if I want to carry macro capability with me while hiking, I usually take a second body and the 100L. That's a ton of weight/hassle. This other rig, I can just pocket. (Have also been experimenting with the new Tamron 35mm, which is almost a macro, and super light/great.)

Point is: yes, when you throw in exciting lenses, people will take advantage of the system.

Incidentally, I got the m1 and 22mm f/2 for $150 together. Plan to sell the 22mm for $100, so I'll have the new system for $50. Also, tellingly, wasn't interested in the m2 or m3 because there just wasn't much to justify the extra few hundred dollars.

If the m1 pans out well, I might even sell my beloved SL1.

Two bodies for hiking is a chore for me. You might want to consider the 24-70 f/4L IS for hiking. For me, it's the perfect all-in-one hiking lens -- it fully covers my landscape needs, it's sealed for a light rain, and it has the 0.7x macro to boot. My 100L has not come on a hike since I got the 24-70 f/4.

It's also in the same neighborhood size-wise as the Tamron 35 you referred to.

I'd personally never lug a large aperture prime hiking unless there was some astro to be shot, but surely your needs may vary compared to mine.

I usually am hiking with a telephoto of some sort. Super heavy. So the macro is definitely a chore. I've often thought about the 24-70 f/4, but I'm not really looking for an all-around lens on those trips, but rather just a purpose-specific macro (was thinking of the 65mm MPE in fact).

But for normal people, I think you're absolutely right.

Bringing the 5x on a hike outdoors? Handheld?! That is ambitious.

I formally retract my suggestion -- you must really love macro and hike with some very patient friends/family.

My guess is this particular patent was a stepping stone to the EF-M 15-45mm f/3.5-6.3 IS STM that was recently released

Yes, that was my suspicion.

Great deal on the m1, but the m3 with the articulating screen and the EVF make it way superior for outdoor macro work.

Still waiting for that elusive EF-M 35mm f/1.8 STM we've heard so much about.

@ tiggy: I hope you spend some quality time with the 22 before you flip it. It is by far the best M prime available.

I see what you did there...

Hang on -- technically there are two now. :

I want an EF-M prime other than the 22/2, and I want to use it this week. How can I obtain one?
