Skromny Tomasz: Odd choice to promote a drone using 5G, basically tech that promises insane speeds over short distances, e.g. you need a tower every X meters for it to be stable. Not exactly what a drone with ancient camera needs, quite the opposite if anything, considering 5G is a major power eater.

I suspect they wanted to throw in a buzzword to promote T-Mobile 5G network, it's not about the drone. Not at all

It's all about the low latency first enabling the use of FPV via mobile networks.

Imager of: “5G”! How about giving us reliable 4g first! The most over hyped useless technology out there right now. 5G failed before it started

Living in Denmark we have 4G connectivity nearly everywhere. I know only few, very few, places, where speed drops down to 2G. Mainly in the shadow of huge dunes or cliffs.

108: Always wondered what was the 5G about ? Better speed so the average Joe can watch his porn clip in hd while riding the bus ? Or the 400 video apps they offer with a two years' subscription in my country ? Or the ridiculous medical application that is " going to save lives" while ignoring that most hospitals have fiber ? Now I know : it's all about drones , down to the bee size ones that are going to spy on you while you're in the bathroom ....jeeez, gotta go and take my blue pill, don't feel well today .

As far as I know the latency is lower than at 4G, which is a deal breaker for some applications. I can imagine, that FPV flying is even not possible with the latencies of the 4G standard, which is why they are using that technology to promote their 5G technology.

Distorted_Light: Very nice skills indeed. However, will there be any company to produce FPV camera which is not so wide? The super wide perspective just make it too unreal for viewers. I know that may change the configurations for the drone operators out of their comfort zones. But that super wide angle experience makes FPV footage pretty boring over time.

Wouldn't it be possible to crop the super-wide 4k videos to a more comfortable 2k? This would though require the pilot to pre-imagine the final picture.

PhotoFactor: Very beautiful and impressive, but I found the choreography a bit random and not as good as it might have been. Just MHO.

Agreed. Impressive footage and flights, but the video is not very harmonic and smooth. Maybe a professional director should put hers/his hands on the raw videos. :-)

Still wondering why nobody is complaining about a full bottle beside of a filled glas . ;-)
Great tutorial though! :-)

Dragonrider: This is way overdue. This format looks like it is more efficient as a lossless codec than HEIF and it handles high bit depth. It should be (finally) a great alternative to .tiff files for lossless storage. Compressed format looks decent as well and if it is fast (unlike JPEG2000) and free it should take off. Let's hope there are no glitches in the release timeframe. Clearly, something of this sort has been used in losslessly compressed raw files for some time. It is just nuts that you can take 40MB raw file and process it a bit and wind up with a 300MP .TIFF or .PSD file. If no information is added, there is no reason the secondary storage should be hugely larger since the only new info is the "guess" that the debayer engine made. Even simple differential coding goes a long ways with most images.

Raw: single colour (R/G/B) per pixel of 12, 14 or 16 bits.
After de-bayer: Three colours of e.g. 16 bits per pixel.
That's the explanation for the increase in storage size.

Peter Kwok: That proves that Leica owners are NOT photographers, but collectors.

You rather mean, the new owner of this item is a collector, while maybe being a photographer too. I don't know him personally, so that's all I can say about him. :-)

Just threw my D7500 plus lens into the campfire. Hoping for a good price in the far future.

Uh that melting plastic smells...

MyReality: Strange, no objections to the (1/2.3)" camera sensor used in this video. If it was stills, there would be all kinds of objection. Is drone footage more forgiving when using small sensors?

It's definitely harder to pixel-peek in movies. ;-)
And yes, I think in video the shortcomings of the applied technology step even more behind the final result. Allusion to still photography intended.

Rod McD: I haven't checked the price of the stuff, but small quantities might be very useful for lining the interiors of lens hoods and lens adapters. Sure all of them are made of black plastics or their alloys are anodised black, but most show surprising levels of reflection when light hits them at an acute angle. Some matt blacks are matter than others.....

You might want to have a look at the Musou black. 100 ml seem quite affordable at 20 € / 2500 yen, shipping excluded, if you really need that feature. There are also local distributors in Europe selling the can for arount 40 €.

2stepbay: I’m all for being creative in post, but not in this way. This is pseudo creativity at its worst.

In my humble opinion, it is just a different kind of creativity. Where's the difference between a real photograph, and a photo realistic painting of a scene, that never did exist? On a smartphone it might even be indistinguishable.
The "fake" in those technologies dissappears, once it is made clear, that it is a created piece of art, not a photography.

chadley_chad: I’d never buy something like a coat from Amazon Basics; as I appreciate the types of materials used, build quality etc. But for a bag; if I can get a copy of an £80 bag for 4 times less, it’s something worthwhile. It may not last as long, but I can buy 4 for the same price. £80 is a lot tbh ... if it was half the price I’d consider it.

Not aware of the details of both bags, you'd then use three times as much ressources for the same thing. Also something to consider, imho.

Photoreader: Fancy lens, but I got sharper pictures of the moon with a 70-300 mm on a DX/APSC Nikon (450 mm equiv.), because I could hold the ISO much lower.

Yes, of course. But looking at 100% magnification I can see much more details on my smaller moon. ;-)

Razewa: Dear dpreview team, why these high iso values that nobody will take in practice?

I was quite impressed with the cleanness of the shadows at those high ISOs. So the images did their job for me in a technically oriented gallery.

The punchline sounds less appealing if it was sponsored by Smith&Wesson. But surely it would have had bigger impact in the social media.

Why is a prism used instead of a first-surface mirror, aka laser-mirror? This would make the moving part lighter and thus easier to control. Is there any advantage to using a prism instead of?

Botifarro: :
No money is worse spent than on software.. as immaterial as fluff.. it's all virtual, except the money you already spent in it. You buy an app, the next it doesn't work with your system's new update, the next the developer stops supporting the app, the next discontinues it altogether.

Easy come easy go.

Maybe I should quit my job as a software developer then. New SW is not needed anyway... ;-)

Long exposure of cyclist passing by: Not achievable with gels. Ditto for trains, cars (not for highway use, of course), fountains, hopping balls (the ones used in ball games like soccer or basketball), etc. I could imagine that I'd had a lot of fun with this device. If it's good for producing nice images? Only time will tell.
