On article DJI Air 2S vs Mavic 2 Pro: which should you choose? (83 comments in total)
In reply to:

yoms: @Dale Baskin

The article per se is interesting, but it should definitely include some kind of warning to tell readers that the comparison will be obsolete, sooner than later, when the Mavic 3 is released (it will obviously be better spec'd than both its predecessor and the Air 2S).

I mean, I totally understand that you cannot compare the Air 2S to an unreleased product. But many readers are not necessarily following rumours sites and are not aware that in X months (and not years), the Mavic 3 will be announced.

This is like comparing the latest M1 Apple computers to Apple computers that have not transitioned to M1 yet. Of course, the M1s will be better than those, but you know for sure that these computers will also transition to M1 (or even M2) chips.

The article should mention this in the conclusion imho. If the Mavic 3 Pro wasn't near the corner, I would not have commented, but given it is I think it's important for readers to include this piece of information in the equation.

There is no evidence at all that the Mavic 3 is due shortly and the rumour sites have been incorrectly claiming it's about to be released since as far back as November and been wrong every time since. The gap between the Mavic 1 and 2 series (and some of the other DJI drones) was two years but we're well past that now so it's meaningless. If anything the release of this drone suggests the Mavic 3 is nowhere near or not coming at all since the Air series was already starting to eat into the M2 series and giving the Air a 1in sensor at a lower price reduces the market much more for another Mavic Pro drone.

Melindra: How do you determine how much storage you have?
I find Google photos a mess, but I don't store anything on it anyway, I don't think.

Go here:

https://myaccount.google.com

You'll see how much storage you're using and then you can click that to see how the usage splits across the different Google products

HowaboutRAW: A high ISO limit of 51,200 is low if this is the same sensor as is in the S1, and Nikon D780/Z6.

(Right, the Sony A7III and A9/II use the same sensor as is in the D780 and S1, but those Sonys have heat blooming issues that limit the bodies' higher ISO capacities.)

Is the S5 using, perhaps, the non-bsi 24 MP sensor from the Nikon Z5 and D750?

The Sony A9 series are not using the same sensor as the A7III/D780/Z6 and they're not even the same technologies, the A9's use a stacked sensor and the others do not.

The article actually states the S5 uses a BSI sensor the same as the S1:

"The S5 features a 24MP BSI CMOS sensor, also found in the S1, which has a standard ISO range of 100-51,200"

ProfHankD: It's the size, resolution, and price of an old laptop. Not exciting. It's also worth noting that a typical smart TV can almost do this too and doesn't cost that much for a vastly better screen. If not, there are devices under $50 that could provide this functionality for a TV. And there are Android tablets with 15.6" screens for under $150. Oh, and all those options have NO monthly membership fees. Overall, this feels like a product that should have come out over a decade ago and be better and/or cheaper now....

I was thinking much the same and the price and specs don't really make any sense, it doesn't look a great display yet it's a high cost with a monthly subscription on top of that. I do still like using photo frames and currently using a 4K Windows tablet for a similar price with a 200GB sd card for photos plus it can sync up to any number of services without a subscription.

JackM: 48mp mode doesn't seem to offer any more detail, just a bigger image (and file).

Not correct. There at tons of samples on the internet of 12MP and 48MP from the Air 2 and many other phones using this sensor showing the same size of objects and the 48 does have less detail and other IQ issues.

Greg Eddinger: I'm dissapointed in DPRs review. This is really just an overview opinion of a camera that's been out for 6 months.

I was hoping to find the normal DPR comparisons of video and photos to previous models. Zilch.

To make things worse, inaccurate information about the backward compatibility of previous generation batteries doesn't help endorse DPRs credibility either. While notiing that the new lens isn't replaceable seeminly lost in translation is that the new lens is twice as thick and tempered glass lens protectors are available.

No mention of the UI changes or other additions or more choices for field of veiw.

I feel like I've been clickbaited to this site. Nothing in the "review" has influenced me on purchasing this camera. I would have been happy to click a referal link to credit DPR but truthfully, this review seems more like Chris felt bothered with having to do it.

I thought I was reading the first page of the review and was surprised to find that was it, I particularly like the competition section which essentially just mentions the Gopro has competition and nothing else.

That's consistent with what I've read about this sensor but I assume the main reason for the 48MP is marketing, I've seen a good number of people assuming the Mavic Air 2 camera is better than the Mavic 2 Pro since the latter is only 20MP. So I expect the 48MP will work well for selling the Air 2

RW Perk: I read it has a 12 MP sensor and made 48 MP with software, and you can't get a raw image with 48 only with 12. That the 48 wasn't very sharp and you could get a better photo with a 12 MP raw and photoshop.

It's a 48MP quad bayer sensor so instead of red, green, green, blue you have four red, eight green and four blue but obviously those pixels are much smaller.

Jwelz: If you've ever used a camera with an optical rangefinder, you would understand how stereo parallax allows you to distinguish distance to an object. You can't focus a horizontal rangefinder on a horizontal object or on objects with a repeating horizontal pattern. My Mavic Pro thinks a horizontal cable, window sill or roof edge is at infinity. Turn the drone 90 degrees so the stereo pair of cameras is perpendicular to such object and it can see the range. Objects at an angle to the stero pair are determined to be farther than they are the closer to horizontal they are. I don't use the collision avoidance. Only cameras using at least 3 coplanar sensors per axis won't be fooled in this way. Optical is still fooled by glass and transparent water on lakes and ponds in down direction.

There is almost half a page of warnings about the shortcomings of the obstacle avoidance system, there are also warnings on the Mavic webpage, the FAQs, the quick start guide and there are also warnings in red when flying the Mavic if there's any problems with the obstacle avoidance system.

DJI in no way claim the obstacle avoidance sensors are a fool proof system and usually people who think so are the ones that haven't read the manual. Given the many warnings in the manual about OA system it's truly bizarre to claim they don't exist.

On article Review: DJI Osmo Pocket (140 comments in total)
In reply to:

winter1: I really like the look of this. Very versatile bit of kit. However I am on the fence when it comes to buying this version 1. A few cons in my book that I personally don't like.

1. Built in battery.
2. No tripod socket.
3. Fixed focal length.
4. Focal length not wide enough?
5. To get the best out of it you may want to spend another £200-£300 on accessories.

I have a feeling v2 will fix a few of those above.

I like this product! Do I need one, probably not and with its current limitations I guess I am going to sit tight for now.

The lack of a tripod socket is surprising as it's really handy on the DJI Osmo mobile 2. It initially seemed a bit pointless since the gimbal is stabilised anyway but it's great being able to just dump the tripod down and then make the adjustments on the gimbal to get the shot I want.

jim seekers: Drones should be banned and made illegal to members of the public, only broadcasters, emergency services and military should be allowed them.

Every aspect of these flights was already completely illegal with a penalty of jail, why on earth do you think restricting access to legal users is going to make any difference at all? It's surprising how few people seem to understand this concept and blaming this issue on a lack of regulation.

Alphaville: No OIS in the telephoto? That sucks

As above there's OIS on the telephoto sensor but not on the main sensor which is a deal breaker for me as I find it very useful on my current phone even though it's a shorter focal length,

Hellstrom: 6"+ phone but a microsd was deemed too big?
With phlablets getting bigger and circuitry being miniaturised, there should be room for dual SD cards in these things by now.

The Galaxy Note 9 does have a micro SD slot, headphone port and OIS on the main camera yet also has a similar sized 4000mah battery.

Given how organised the thieves were I'd worry they'll hit the shop again as there's plenty other expensive equipment there.

I became aware of Ffordes a few years ago when someone on the forums spotted a second hand Olympus FL-50 flash for sale, I looked up the site and was very surprised to find it was nearby as I live in a rural area and had no idea there was such a specialist camera shop nearby. Very helpful staff who know what they're talking about and with a good range of equipment, I hope they recover from this.

This is a very strange review in that it doesn't make even a single reference to the GoPro Fusion's main rival which is the Garmin Virb 360. It's in a similar price range and also features the ability to produce a standard fixed video. It also seems to better the Fusion in quite a few areas as its lower, wider design is better for helmet use, it only needs a single SD card slot instead of two and the Garmin software does allow you to choose a custom angle, zoom etc. to produced a non-360 video. The stabilisation effect it can produce is incredible and it has such a wide range on fast mountain bike trails when the bike is going through tight, twisty turns it can actually do better than a mechanical gimbal. The Garmin was out months before the GoPro so that's not really an excuse either.

I was wondering how the Fusion was holding up now having bought a Garmin at the time when I weighed it up against the Fusion but I didn't find this review really at all useful.

sohus: To all the people complaining about talking trash about crowdfunding:

- Crowdfunding is investing
- Investing means taking risk
- You don't invest with money you don't have
- Most people are poor investors

The only one to blame is yourself. Make better investment decisions. Of course there are scams on crowdfunding websites. But there even more retail scams so if you don't pay attention you get ripped off as well in traditional retail.

These are all new companies, taking huge risks and bets against the odds, taking on the big guys which everyone here is always complaining about our not innovating hard enough. Sometimes they manage to pull it off, which is amazing, but other times they run into the reality of supply chain management (companies like Apple who buy all available parts in the market, so even a company like Nintendo couldn't get enough parts to produce their Switch console at market demand).

Crowdfunding is absolutely not investing because crucially, backers receive no share of the company - it's simply preordering an item at a slight discount and almost no protection. Investors can take risks because for the companies that do pay off, they'll receive much more than their initial investment back which will never happen even on a successful crowdfunded project.

Och Elo: I firmly understand people's needs differ. But I just don't get this near obsession with shrinking cameras so they are "pocketable". I guess the idea is you can discreetly take the camera anywhere and anytime. But these days most phones can ably play that role. If the idea is you can have a camera ready to capture that fleeting moment, I've lost these fleeting moments because I have to pull the camera out of a pocket instead of having it ready to go right on my neck or wrist.

If I'm actually on vacation, I definitely don't keep my camera in a pocket, it's around my neck or wrist so I can capture a lot of images quickly. Not to mention I don't want to keep a camera in my pocket where it can catch dust/lint which is really bad for these fixed lens zoom cameras.

Don't get me wrong, small and light is appreciated. But I usually keep these in a small bag for storage and around neck/wrist when taking images. For pocketable, phone is fine. YMMV.

Phone cameras have certainly improved a lot, I thought my older Note 4 was a good shooter for its size but the Note 8 is even better. However there's still a big difference in performance between the phone and the RX100 mk 4 I always have with me in my pocket. It's not just the much cleaner high iso and wider dynamic range, it has a zoom (I know the Note 8 does too but it's a weaker sensor than the main wide angle sensor) and simple stuff like it's easier to use with gloves on which is handy when I'm out cycling.

I'd love a bigger sensor but I think Sony have managed to strike a great balance as the RX100 is small and light but keeps a decent sized sensor with a fast lens.

I had no interest in vr which I saw as too expensive and too limited until I had the chance to try an occulus dk2. I started off with a little roller coaster demo and I was immediately sold by the technology, there's no way to describe the incredible level of immersion and would recommend people try it out particularly as a lot of people seem to equate the technology to 3d and its really nothing like that.

I since bought an HTC Vive and there's a lot of easy criticisms to make - it's extremely expensive on its own never mine that beefy pc to run it, the headset is heavy, the cable can be annoying and the room scale system is a fiddle to set up. I was getting a bit short tempered with it when I was first trying to set it up and really wondering if it was worth it until I fired up the steam vr intro where you stand in a small room which gradually folds away leaving you in a large open warehouse type building then pick up the two controllers which have a perfect virtual pair which match their movement in vr which just feels amazing.

A lot of people think of the horrible wiimotes when thinking of motion controls but the Vive controllers are nothing like that, they track the motion quickly and accurately making it feel like you can interact with the virtual environment. Combined with the clever room scale it takes it a level beyond seated vr. I've demoed it to a variety of people and the fact they can just look around and move their hands around makes it so much more accessible than needing a controller. I was particularly amused at my mum pinning herself against a wall during valve's mountain top experience as she didn't want to fall over the edge.

So far we're just scratching the surface of vr and I can't wait to see where it goes. There's so many clever uses of it already, you can go into a virtual lounge, share your screen as a large TV on the wall and have three other virtual people sitting beside you that you can chat to and they can see your screen and hear the audio. In a multiplayer first person shooter, the game can give an eerily accurate in game version of you since it knows your height, where your head is pointing and where your arms are meaning you can naturally gesture to your team mates.

The camera technology for 360 vr capture is obviously very high end at the moment and the consumer options are not really any where near good enough to meet the high resolution and framerate demands but they will improve. As will the headset technology, HTC have gradually lightened their headset, they're releasing a wireless option and a new head band to make it more comfortable.

Howwver even looking forward to all the improvements, I still love the vr setup right now as it seems almost unbelievable to be able to have such an incredible piece of technology in my house I can use any time.

Reactive: Dale, there is one fundamental reality you missed, which I thought would be in reason 6, "You’re stuck in place"... Exactly. You can't move about while wearing a VR headset without crashing into your surroundings. Well you can, but only a metre or two until a) you trip over a chair, or b) the headset wire pulls tight. Obviously, VR must become wireless to give it any chance at all, but after that only people who own a football pitch or a vast unobstructed warehouse floor will be able to run about and pretend they're really IN their immersive environment, holodeck style. That's why VR will fail. Great for flight or driving simulators, or niche training applications, impractical for everything else. Only Augmented Reality will gain any mass following, when we can click a button on normal looking spectacles and get instant translations or directions overlaid on the real, hard, world around us. Oh, hang on, didn't Google think of that years ago?

Even in its current limited implementation, the Vive and its lighthouse tracking system is much better than you've described. It's clever room scale system allows you to move about still within a limited area but the clever boundary system means you don't bump into things as the game knows when you are approaching the edge of your playable area.
Also when in a room scale game, it doesn't feel like you're limited to a small play area at all. I find it quite disorientating when removing the vr headset as you don't feel like you've just been moving around a small area.
