24-70mm f/2.8-5.6   :'( :'( :'(

if you can't handle a 2.8-5.6 on a 1.6 crop camera, you have a problem.

24-70mm f/2.8-5.6   :'( :'( :'(

if you can't handle a 2.8-5.6 on a 1.6 crop camera, you have a problem.

They kind of have a point. Someone correct me if my math is wrong, but aps c vs 1" type sensor is about 3 times as much light, or vaguely around 1 and a half stops.  The Sony rx 100 v is a 24-70mm equivalent, 1.8-2.8.  2.8 is two stops larger than the 5.6 of the new canon, while the larger apps-c sensor only claws back 1.5 of those stops of lost light. 

Is there much of a benefit to the larger sensor in this case? Can anyone explain why a larger sensor might still be better here?

i dont think it will be 15-44/1.8-3.5.

the patent involved (most likely) was 15-43 1.8-3.74

from the actual patent:

Focal distance 15.65 28.94 42.90
F number 1.85 2.77 3.74 Zoom ratio: 2.74
Focal length: 15.65 29.18 42.90
F No.: 2.06 2.99 4.00
Half angle: 41.12 25.09 17.66
Image height: 13.66 13.66 13.66
Back focus: 8.52 8.01 7.20

thanks rrc, missed that one. Interesting. So a 15-43 /1.8-3.7 lens may be possible, but looks to be protruding quite a bit from a G1X size camera body. i missed out on the specs of that patent. looking into it i found reference to another Canon patent http://www.*********.com/does-this-canon-patent-for-a-15-43mm-f2-4-lens-for-aps-c-sensors-refer-to-the-powershot-g1-x-mark-iii/ for a 15-43mm f/2-4 lens with different, but similar specs:

Zoom ratio: 2.74
Focal length: 15.65 29.18 42.90
F No.: 2.06 2.99 4.00
Half angle: 41.12 25.09 17.66
Image height: 13.66 13.66 13.66
Back focus: 8.52 8.01 7.20

i guess we have to wait and see what comes about. if the lens is faster and IQ still decent enough, the better. :-)

I'm actually pretty jazzed about this one. I have an original EOS M and have been considering upgrading.  This might be my purchase right here since they are going to an APSC sensor with what appears to be (as of now) a good bit of bells and whistles.  Perfect compact camera.  Wondering if price will remain around $700 like the current model.

wrong embodiment that's why it's always better to look at the actual patent ;)

i'll be jazzed if they make a 15-45 1.8-3.5 for my M's.

I can bet that there is no 4k and it's going to look like the G5x/M5 with the little hump for the EVF.
So disappointing.  They would had been better to stuck with the 1.5" sensor and given it a decent sensor.  That was the real problem with the II.

Sony keeps leading and poor Canon keeps spinning to Canonitis....To never go the full step you really need to innovate and take over the market.
From a Sony point of view, they innovate because they have no other products that would compete against their own. Where as with Canon and Nikon, they release a full frame mirrorless, now that competes with their DSLRs. Same goes for DSLRs...include 4K, now you're competing with their Cinema EOS cameras

yes.
but.
wouldn't it be better for Canon (or Nikon) if customers buy Canon (or Nikon) mirrorless cameras and lenses or 4k enabled cameras instead of switching brand to Sony and Fuji and Panasonic (4k video)?
"cannibalization" by own products is no problem - especially if the newproducts have better margins. mirrorless cams can be made at significantly lower cost and sold at higher prices than mirrorslappers - look at EOS M5/M6 vs. any "Rebel class" DSLR. or look at Fujifilm's pricing for their crop sensor MILCs ...

summary: not offering compelling mirrorless systems for both APS-C and FF sensor size and not offering SOME cameras with 4k video capture is ultimately stupid of Canon (and Nikon) and has cost them a lot of money already. in case of Nikon it seriously jeopardizes that companys future.

in the real world, you always have conflicting priorities between resource allocation and what you'd like to get done.

it's not a simple matter to make 4k cameras, because those resources then can't work on something else.

I believe the aperture referenced for the G1X M3 has already been converted to a 35mm equivalent.

The Sony RX100 V has a 35mm equivalent 24-70mm f/4.9-7.6 lens.

The G1X Mark III may have a 35mm equivalent 24-70mm f/2.8-5.6 lens.

it is really simple. Anyone from GoPro to Sony can do it. And if Canon would not SQUANDER precious resources on "yet another series of mirrorslappers" in late 2017, they could have come out with a KILLER FF MILC system 1 month AHEAD of Sony A7 [Oct 2013!]

24-70mm is way too short for a camera like this.
A waste of an APS-C sensor.
Something like a 24-120mm would be a better seller

How so?  Can you not IMAGINE the size of this thing if it were to have a 24-120mm lens?  This is APS-C now, and with those focal lengths and to keep the lens speed to any practical level it would surely no longer be a 'compact pro travel camera'.

I suspect the desire to retain the roughly same overall size and the decision to move to APS-C is driving the decision to limit the range to 24-70mm.

The question remains does this neuter the flexibility of the camera? - i've certainly found the G1x MkII quite flexible. It has quite a good wide angle as well as a workable portrait focal length (if nowhere near the level you'd like to have if physics was no issue).  Bokeh is barely there.

Sony (as the E mount) had to compete with the A-mount also. The A-mount is still not dead (kind of :) ).
