It's no longer a rumor. The G3X is for real (1-inch sensor and 25x zoom)

This is one large sensor compact (LSC?) camera I'm actually interested in. 25x zoom makes it so ridiculously practical for travel and other such things.

I just hope the shutter lag and AF are better than the G1x. Drives me NUTS when my other camera is a 7D.

Ohhh, i wonder how portable it is ,looks abit bigger than the g1x mk11 ,maybe a bridge camera size.I also wonder what price range it will be in,the g1x mk11 was almost in the DSLR range.

Any idea if it's f2.8 all the way like the Panasonic FZ200 ?

Most likely 2.0 at the wide end and assuming at least 6.3 at the 400mm or longer.

HMM? Smaller sensor than a G1X II in a bigger package. I don't see this ever making it to production. It was dead when this thread was started.

But it has a 24-600mm lens which is the selling point. Shooting at 600MM RAW is going to be the reason why someone would want this.

I don't get the "1.0-inch sensor" specification. If that were the diagonal measurement, it would be almost as large as an APS-C. But Canon's specs on the lens say its actual focal length range is 8.8-220 mm, making the crop factor (relative to a 35mm frame) about 2.7, so the sensor must only be about 60% the size of APS-C. The aspect ratio of the sensor is 3:2, but no matter how I do the math I can't come up with any combination of L+W that adds up to anywhere near 1 inch/25.4 mm. The best I can figure out from that crop factor and aspect ratio is about 8.8 x 13.2 mm. Maybe if you add the length and the width. like shipping companies do, you get 22 mm which is sorta kinda close to an inch.

Maybe if you add the length and the width. like shipping companies do, you get 22 mm which is sorta kinda close to an inch.

The 1" sensor size refers to the video camera method of naming sensor sizes. It is actually 1/1' which measures about 12.8mm by 9.6mm and results in a crop factor of about 2.7x

Sensor formats of digital cameras are mostly expressed in the non-standardized "inch" system as approximately 1.5 times the length of the diagonal of the sensor. This "optical format" measure goes back to the way image sizes of video cameras used until the late 1980s were expressed, referring to the outside diameter of the glass envelope of the video camera tube. David Pogue of The New York Times states that "the actual sensor size is much smaller than what the camera companies publish – about one-third smaller." For example, a camera advertising a 1/2.7" sensor does not have a sensor with a diagonal of 0.37"; instead, the diagonal is closer to 0.26".[26][27][28] Instead of "formats", these sensor sizes are often called types, as in "1/2-inch-type CCD."

Mike, thanks for explaining that. Talk about specmanship! That's consistent with my guesstimates. Here's another explanation I found:

https://en.wikipedia.o​rg …_sensor_formats​_and_sizes (external link)

From what the Wikipedia article says, the "inch" rating is based on the usable image area of a video tube of that many inches diameter. I guess that's no more anachronistic than referring focal lengths and sensor sizes to their 35mm equivalents. I do it, even though I've never used a "full frame" DSLR and I haven't shot 35mm film since I got my 20D in 2004!

It's basically a superzoom but with a significantly larger sensor than most superzooms.

July 30th, though you can buy it right now on eBay from Japanese sellers.
