Xerien: There are no good third party camera apps for Android to begin with......not sure how this is relevant.

GCam is literally the only "third party" camera app anybody is interested in... well anybody who isn't using a Pixel.

Lord Powershoter: Ever since this lens was announced something is bugging me. Maybe I find enlightenment here: Why is this lens such a big deal, particularly the aperture? Leica has had the f0,95 Noctilux since 2008.
Especially because Nikon advertised their huge mount so much. Well, the M-Mount is smaller yet also has a f0,95 lens. What am I overlooking?

Because the 0.95 Noct is a one-trick pony that isn't even optically that great. If you aren't using it all the way open, the Summilux is a better all around lens.

SigmaChrome: Looks like the DSLR and the much maligned OVF is still in demand - unless Nikon has misread the marketplace. Long live the Optical Viewfinder!

OVF's are maligned by Sony shooters who have never had to work in professional sports setting.

Nice to see the DPR crew come up to Vancouver for day excursions on these galleries.

Hint: if you look at how long it took 28-75 RXD's to ship, dealers are probably piling on the orders with the expectation that it will take forever to fulfill. The customer demand is high but it isn't that high. Tamron is technically correct they can't meet all of the dealer orders, but the quantities that are being ordered are probably going deeper into the future than normal because of past history.

Sheesh these comments. Did you never work in retail as a youth or have children who do? It's no laughing matter when this happens to you.

tkbslc: I struggle to think of photographic opportunities I've gained in the past 5+ years thanks to upgraded gear. It's harder to sell gear when most of what has been produced in the past decade is more than good enough to take high end, professional photos (not to mention the amateur ones most of us take).

The used market is just murder out there right now. If you want to sell DSLR gear to move to mirrorless, there just aren't that many takers.

> And to think I believed all the moaning and groaning about retail margins being so thin.

MAP prices leave a little bit of margin for this sort of thing. Since everything is minimally advertised priced these days, an online retailer can do something like this, which is basically a way to discount below the MAP pricing level. If you walk into a brick and motor store, the price on the shelf can be in some cases lower than the advertised online price.

BobT3218: As always, history is written by the victor. It seems China is busily doing just that.

> I sorta feel China lost that one...otherwise it wouldn't have its panties in a bunch.

Sort of yes and sort of no. I've asked a few people who have since emigrated out of China what their memories were of that time. Everybody knew something was happening, but nobody knew the full extent. Chinese people outside of China saw massive amounts more footage than anybody living in China at the time, so most of what happened is know documented in the diaspora around the world. In a sense though, China did "win" on this one, because the generation born afterwards is very disconnected from the lineage of history, and is very materialistic and self-focused in its outlook. The ironic thing is, you guys have no idea how many Leica cameras are in China.....

MinAZ: So black holes are not actually black, they are orange?

@arandino To be even more pedantic, the reason why we don't see any light from the black hole itself isn't just because of gravitational pull; this is where the pop-sci explanations leave out the boring subtle stuff.

We don't see into the black hole not just because gravity pulls things in. In fact, light does "escape"... there are two things that happen as you get closer to the blackhole... to an outside observer it appears that time is slowing down as the object falls in; at the event horizon it would appear to an outside observer as if time was frozen for that object; we would never see it fall in. However, we don't see at all because whatever light that an object emits or reflects gets redshifted to infinity by the gravity as it approaches the event horizon. So hence, no observable light escapes. Beyond that, yes all paths lead to the center of the black hole.

Just to be pedantic: the diameter of that black portion isn't the event horizon, it's the outline of the innermost stable orbit. The event horizon is slightly smaller, but anything between the event horizon and the orange disk would be in an unstable orbit that would decay into the black hole.

They are black if they aren't "feeding". Matter falling into a black hole spirals at extremely high speed before it crosses the event horizon; the heat and friction generates radiation which we can see.

richdm: I'm fairly sure that the hot gas isn't escaping the black hole. Here's a description:

The X-rays come from hot gas orbiting around the black hole in an accretion disk. As the gas orbits, magnetic stresses cause it to lose energy and angular momentum, thus spiraling slowly in towards the black hole. The orbital energy is transformed into thermal energy, heating up the gas to millions of degrees, so it then emits blackbody radiation in the X-ray band.

Once the gas gets closer than a few times the horizon radius, it plunges into the black hole, so while some X-rays can still escape just before the horizon, most are emitted a fair bit outside.

https://physics.stackexchange.com/questions/24958/how-can-a-black-hole-emit-x-rays

Credit pop-sci journalism for this confusion. "Nothing can escape a black hole, not even light"... it gives people the impression that a black hole is like a cosmic vacuum cleaner that literally sucks in everything regardless of distance. Things can orbit a black hole without falling in, and because the gravity is so strong, gas and dust in the accretion disk orbits at a significant portion of the speed of light, which generates the light and radiation that we see.

Gesture: Why hasn't battery technology gone further? Aren't batteries still the weakest link in our digital camera?

It is noteworthy how many lithium batteries get shipped unidentified from eBay, Amazon, etc. sales.

@Revenant

While you can use technology and manufacturing methods to mitigate the danger of a battery, the danger itself is chemical and fundamental in nature, that's my point. We have an expectation that technology can overcoming anything these days, and while true, it doesn't pay respect to the very physical limitations and laws of nature that engineering and technology have to overcome.

> Surely a device that makes use of chemistry would count as technology?

Ummm.... Look at the eletrochemistry appendix in the back of any chemistry textbook and match up the cell potentials. You react Lithion with any other element and it's basically a firebomb; a battery just does that chemical reaction in a slow controlled way. So that's why batteries are inherently hazardous (to varying degrees) no matter what the construction.

It's not "technology" it's "chemistry". If you want higher power density, the chemistry gets more volatile and there's no way around that.

stevevelvia50: I use the EM1 Mark ll, and I don quite understand these videos. I have got some insight from the comment section in 4/3runors, that the EM 1X is pretty impressive. Don’t quote me on this, I’m just the messenger, but someone who claims to have tried the camera out, says the high iso is on par with the Nikon D500. The autofocus overall is equal to the D500 and a9, and the video is easily up with the Panasonic GH5, only with 7.5+ ibis. There are three zooms, that are amazing from what he says, and there will be no stabilized 40-150 2.8. On the 24th we’ll know. Again, this is just what I’v read from a source in the comment section of 4/3rumors... I treat this as a strong rumor, but certainly don’t rule any of these claims out!

> high iso is on par with the Nikon D500

I don't see how this is possible, but would welcome it if it was true. Not sure how read and dark current noise can be improved further to make up the difference in pixel well size; modern cameras are primarily limited by quantum shot noise at high ISO.
