junk1: Is this any more reckless than people playing baseball in a neighborhood? Ever get hit by a baseball in the head? Or imagine what a baseball could do to a window or siding. Would we charge the person with reckless endangerment? I'd rather have a drone hit me than a baseball "line drive".

"Between 2004 and 2009, there were 24 sports-related deaths in high school athletes."

"40 children died from 2001 through 2008 as a result of playground-associated injuries."

"An estimated 712,700 children ages 19 and under were seen in emergency departments for injuries related to football or basketball in 2013."

There are way bigger things to worry about than injuries to bystanders from small R/C aircraft.

Biological_Viewfinder: Drone buyers should have to go to jail up front.

Same with automobile buyers, airplane buyers, and heaven-forbid, buyers of kitchen knives.

andyyau: "were not caused by faults in hardware or software, but by the devices' batteries"
Batteries are not hardware? Samsung you are genius. lol

140 phones out of 2.5 million burned. That's one in almost 18,000 or 0.0056% of the total. That's a very, very hard type of problem to detect.

DiegoRodriguez: So, the G9X 's major flaw was its lens, they make a Mark 2, and... they keep the same lens...

That looks decentered to me. The bottom of that same image is just fine. It's just the top that's OOF. I found an S120 that was similar, but most of them are just fine.

"especially since f4.9 rubs you so close against diffraction on a 20mp 1" sensor"

No it doesn't. MTF still in the 0.6 to 0.7 range.

No, the ZS100 is 44mm thick versus 31mm thick for the G9x. That a huge difference when it comes to pocketability.

The S110 and S120 had a range of 24-120, but a 1/1.7" sensor. To get that range in this sensor size, you need both a bigger lens and a slower f-stop. Frankly, I'd give up f-stop to get range in this camera. If it were 24-120 equivalent and f/2.8-f/5.6 I'd be more interested than I am now. When I really need low-light performance, I take my SLR anyway.

"5.8 1/2.33" is greyscale resolution limited by diffraction at < 3 MP"

Not true at all. The MTF is still almost 0.3 at 12MP.

norman shearer: A tilty screen could have been added with negligable difference to the size..

It's more like 3-5mm thicker. And that does matter for pocketability. If the camera doesn't need to be pocketable, the G7X series is better gear.

That's not true. It would have made it thicker.

I have an f/5.8 (at the long end) 1/2.3" in my pocket right now, and it's mostly okay. f/4.9 and 1" is way, way faster than what I have now.

What was wrong with its lens other than the range?

DPRevievver: let's compare RX 100 (2012) vs G9x2 (2017)
28-100mm vs 28-84mm
F1.8 - 4.9 vs F2.0-4.9
10FPS vs 8FPS

31mm thick (Canon) versus 36mm thick (Sony).

31mm is borderline too thick for all-day pocketablity to me, which is why I've never even considered any of the Sony's. Heck, I didn't even buy an S110 or S120 because of their 27mm thickness over my current camera which is 25mm thick and has curved and beveled edges which make it much more comfortable.

Lee Jay: Someone wake me when phone cameras have an optical range of at least 24-100 equivalent before cropping, optical stabilization that actually works, and ergonomics that don't completely suck.

Manual mode on a cell phone makes little sense to me. No focal length control, no aperture actuator so you're always shooting wide open (which is like f/15 or so on full-frame), no effective flash (LEDs are all but useless), ISO is just final image brightness so all you can really control is shutter speed, and with either missing or really lousy OIS and really lousy results at even modestly high ISO, there's not much control there either because you're usually boxed into a corner.

Most of my favorite shots taken with my pocket compact were taken either at 24mm equivalent or at 50-170mm equivalent. My three all-time favorites were taken at 45mm, 86mm and 112mm before cropping. I would have missed them all had I been using a cell phone camera.

Well, in four years of having a "good" smartphone camera, at least I'm up to double-digits on keepers. 12 at last count.

Actually, a couple of them are printed quite large (over 40" in the long dimension) and hanging on the walls where I work. A few others are hanging in my house or in the homes of family. And many of them couldn't be taken with a cell phone because the focal length wasn't near 28mm equivalent.

I use a pocket compact now. No current cell phone camera comes close to being sufficient for random, general use.

Everyone who owns an ILC should get a Rocket Blower. Simple, cheap, reliable, effective.

You've got to be kidding me.
