According to mirrorlessrumors.com and source link: https://wellsfargoadvisors.mworld.com/m/m.w?lp=GetStory&id=587442111, Canon is going to release the G1X with 1.5-inch 14.3-mega-pixel CMOS image sensor and a 4x (28-112mm) optical zoom lens. Shipping in February at a $799 suggested retail.

I hope the admin can confirm whether this is true or not. The camera seems quite nice.

Canon U.S.A. is unveiling two PowerShot Elph-series point-and-shoot cameras and a new flagship Power-Shot G-series model. The G1X (shipping in February at a $799 suggested retail) will be positioned for advanced amateurs and professionals looking for a walk-around point-and-shoot model and offers a large 1.5-inch 14.3-mega-pixel CMOS image sensor and a 4x (28-112mm) optical zoom lens.

It is said to have a shallow depth of field and an aperture range of F/2.5-16 affording better low-light capability.

Other new features include 14-bit RAW file support, a new DIGIC 5 image processor with improved low-light support, high-speed burst HQ shooting of up to 6fps/4.5 fps at full resolution, multi-area white balance adjustment, expanded Smart Auto settings, child-weighted face detection system, handheld night scene and HDR mode. It will shoot up to FullHD 1080 video and includes a 720p Movie Digest mode to automatically compile a video log of all still shots.

Am I wrong in thinking that sensor measurement is way off?

Isn't 1.5 inch (diag, I'm assuming) larger than full frame?

1.5" appears to be between Full frame and APS-H (1.3x crop)


1D4 = 33.5 millimeters = 1.3 inch
1DX = 43.3 millimeters = 1.7 inch
G1X = 38.1 millimeters = 1.5 inch

1D4 = 33.5 millimeters = 1.3 inch
1DX = 43.3 millimeters = 1.7 inch
G1X = 38.1 millimeters = 1.5 inch

Although that is how it might appear at first glance, the inch system for sensor size is not directly translated to diagonal length.

For example, a 1/2" sensor is 8.00mm diagonally, a 1" sensor is 16.00mm diagonally (just a hair bigger than Nikon's CX sensors on the Nikon 1 series). 
The 38mm you have up there refers to the outer diameter of the image tube that would have been used in television cameras of the old.

Following the proper conversion, which is roughly multiplying the inch measurement by 2/3 (not exactly), you get a sensor that is 24mm diagonally.

Interestingly, the Canon APS-C is 2-3mm bigger diagonally that this supposed 1.5" sensor, which is odd, since Canon could cut research and development, and production line costs and just stick a APS-C sensor inside their new compact ... though, either way, the lens would have to be gigantic (by compact standards) to satisfy the rumoured zoom.

This has been hashed out in the newer thread.  I'm fairly certain the spec should read 1/1.5", not 1.5" - that would make it a 2/3" sensor, exactly the size the Fuji X10 uses.

Not me, clearly.  :-[

The big sensor definitely makes it an interesting offering!

Curious how in the light of things that this topic was highjacked with the intro of the G1X which turned out not to be a Gx machine, bearing in mind that the original intention of the author of the subject heading was a CR1 on the introduction of a Gxx camera which so far has not materialised.
Just shows how long this subject has been simmering for, as a Google search will show.
Sorry for resurrecting this subject, just feeling let down and frustrated especially after two new Powershot models were promised this month neither of which turned out to be a Gxx model after all.
I wonder what happened to the source of the original CR1?
