On Dronestagram contest winners announced article (116 comments in total)

What make these pics look different from when taken from a plane, balloon, helicopter, paraglider or UFO ?
These are just aerial shots...that do not require a special contest IMHO.

24bit: Great pics, but what happens when the drones motor fails and falls on the crowd of people in the stadium below !

And what about drunk drone pilots ?

vFunct: This camera isn't for the idiot that thinks a bigger sensor is better.

You are right. This camera is for idiots who think an expensive camera is better...

These pictures of natural sea water splashes are much more interesting than those artifical paint splashes over the fields...

I do not mind photographers using techniques to show us frozen slices of time that our eyes cannot catch. If not always artistic, I find it somewhat instructive and/or amazing.
But, is there anybody out there...to sue these polluters ?

@Der Steppenwolf,
Are you, too, so ignorant that you do not know ignorance can be cured by learning ?

I like the color rendition, like the one of my XZ-2, but definitely not better than most 1/1.7" from other manufacturers as said below. My old 7MP 1/2.3" sensor PowerShot A720 IS takes sharper pictures than this camera. I downsized picture ISO125-P6050380 to 7MP to compare with the A710, then to 2MP to be seen on an HD TV screen but picture still shows lack of sharpness...

What ? This lovely crafted Leica body does not have a tripod screw aligned with the lens ?
Something impossible to do for the Leica engineers ?
If they could not do this, what else did they not manage to do ?
Definitely a no buy for me...

tt321: NO touch screen! What are they thinking?

You use the EVF because of its higher resolution than the rear LCD, maybe ?

EthanP99: Just so we're clear, f4 is now considered "fast lens" ?

@NetMage,
F4 is F4 independently from the sensor size.
Did you ever see a lightmeter which requires you to select the sensor or the film size ? Never...
But, when you compare two sensors (whatever their respective size) the one with the better SNR at high ISO makes a "faster" camera, everything else being equal, because you can push ISO higher for the same IQ.

On Sony Cyber-shot DSC-RX100 III First Impressions Review preview (2979 comments in total)
In reply to:

Karroly: The RX100 III is not the only P&S camera that focuses with the aperture stopped down (when a stopped-down aperture is selected by the metering system or user). The XZ-2 does it too, but the XZ-1 does not. All the (D)SLRs I own(ed) focus with the aperture wide open (at least when using the viewfinder. I did not check and/or notice when using liveview). This seems so plain stupid at first glance, that there should be a good reason that a camera engineer could explain ?

@unknow member,
Question was about P&S, not DSLR...

Thank you for this clarification, but I already know all this technical stuff...
" DSLR focus is based on phase of light, which does require some contrast but not nearly as much as true Constrast Detect AF."
That is why PDAF on DSLR is generally specified to work smoothly with lenses equal or faster than F5.6 wide open...

With DSLR AF, light does not go to the viewfinder but to a sensor located in the bottom of the mirror chamber (this is the light metering sensor that is located close to the pentamirror or pentaprism). Stopping down during AF leads, as you mention, to a greater DOF. The consequence is unfortunately not a faster AF because, if there is not enough light, contrast can be not high enough to focus. I own both XZ-1 and XZ-2 and I can say XZ-2 hunts in low light, where the XZ-1 does not, because of that. Moreover, the greater DOF may lead the camera to focus on a region that does not match the exact distance to the target. The result is a DOF on the picture that is not evenly distributed in front of and behind the target and this may be noticeable.

Lab D: I'll be curious to see what the LX8 announcement does to this camera. It will shoot 4K video and also have an EVF. Rumors are it will have a good size sensor. The GM1 (with even larger sensor) body is smaller than the RX100II so this could get interesting.

Larger sensor means bigger lens for same equivalent focal length and speed, thus less pocketable :-(

Note : I aware that today cameras also shoot video and there is no other possibility than focusing at working aperture in this mode. So, did the camera egineers use the same focusing routine when shooting stills or video for the sake of a smaller, but not trully efficient, software ?

peevee1: Vertical landscapes. They work. Too bad they are not suitable for TVs and monitors.

For sure it works. Obviously to me, either horizontally or vertically the photographer took care of framing and composition.
You wrote : "Too bad they are not suitable for TVs and monitors"
I think exactly the opposite : today screens are not suitable for vertical framing. During the "reign" of analog films, slides could be seen on big square screens in both directions with the same size. As I was shooting mostly slides, I miss this capability today with digital screens. I hope one day someone will manufacture an affordable 1920x1920 pixel display (and next a UHD one...) for the sake of viewing stills in both directions without compromise. And big 1:1 pictures too...
