I like the idea of a 16-120 zoom for the EOS M!

So do I, although a 15-85 would be just a good.

That sounds great!  I like the idea of not going too ambitious with the focal length.  That would satisfy most of my travel telephoto needs - hopefully without an optically crippled design.  The EF-S 15-85mm is a great lens.  It was hand's down my favorite EF-S lens.

+1

That could / would make a great walk around for the EOS-M (I love my 15-85mm on my 7D, similar range).

(note: mods...) I expect there is/was a typo in the post 51.87 should be 15.87, as the corresponding Half angle ω = 39.65....

Hmmm... I wonder what 'example 2' is...    ::)

I'm not a brand-fanatic. What I do appreciate is using my 7D and 350D cameras along with a host of lenses & many accessories to capture quality photos, and share with friends.

16-120 sounds interesting but I am more interested in
(1) a f/4.0 zoom, e.g. 15-75mm with GREAT IQ and a
(2) f/2.0 40mm compact lens (with telephoto construction to minimize size) with GREAT IQ, IS and a good close focus capability (1:4 would be sufficient for most purposes).

But that's just my "needs" ...
TOOLS: EF-S 10-22 | 60 || EF 2.8/24 | 2.8/40 | 2.8+2.0/100 | 4.0/70-200 | 5.6/400 || 2 x 40D || 2x TC ||| 600D for video ||| EOS M + bunch of FD chrome rings

Me too...
Add 80/2 and more interesting telephoto than 50-200 5.6.
Too much wishes for the new year...

Dear Friends.
Yes, that Sound great for me as new toy too.
Any ways, Can Canon Company make The  Adapter to use this EOS-M Lens to use with our Big Brother Regular EOS  ?
Sorry, That Is the stupid Question . Yes, I know, We do not want  to use the Cheap Lens with our High cost Canon Body.

This would be the fourth lens in the EOS M lineup which contains a 22mm focal length.

Is this really necesssary? I would like to see a focal range from maybe 35-150mm or so.

Regards,
Frank

Could be a good walk around for the camera that Canon USA seems to have disinherited
5d Mkiii; Eos-M (with M-22mm, M-18-55, and EF adapter); 50 f1.4; 40 f2.8; 24-105 f4; 70-200 f4 IS, 70-200 f/2.8 IS  ii; 100L f/2.8 Macro; 1.4x iii; 2.0x iii; 28-105ii; 17-40; Pro-Optic 14mm f2.8; 100-400L; 300mm f/2.8 ii; 430 EXii and a whole lot of stuff

Is there something in the patents that indicate these are for the EOS-M? How can you tell?

Such an adapter would need optics, since the flange focal distance (mount-to-sensor) is short for EF-M lenses.

This would be the fourth lens in the EOS M lineup which contains a 22mm focal length.
Is this really necesssary? I would like to see a focal range from maybe 35-150mm or so.

A UWA lens, a prime, a 'short' walkaround lens, and a 'long' walkaround lens makes perfect sense.  The patent also has a superzoom (18-200).

Consider EF-S lenses - 10-22, 15-85, 17-55, 17-85, 18-55, 18-135, 18-200, that's 7 lenses covering 18-22mm (even counting all the 18-55 versions as one).

Consider EF lenses - 16-35, 17-40, 24-70/2.8, 24-70/4, 24-105, 28-135, 28-300, three 24mm primes, two 28mm primes, two 35mm primes (not counting the slower ones recently replaced by IS versions).  How about four 70-200 zooms, three 70-300 zooms plus a couple of cheap 75-300s, and several primes in that range (meaning at least 10 lenses of that focal length for every prime).

Choice is good - stop complaining!!   ;)

The short back focus distance, presumably.

Thank you, Sir, Dear Teacher Mr. neuroanatomist.
If Need Another Lens for The Lens adapter, I would rather use my 20  years old , Tamron, 28-300mm. F/ 3.5 - 6.3 With EOS-M to EF Lens adapter = Better.

Thanks to answer my question. Have a great Sunday, Sir.
