ProfHankD: So, how do you know that there is actually a drone out there? It would be fairly easy to computationally render your flight from a terrain database. Think of it as a sort of "Touring" test. ;-)

It was very clever, mind you, he is a professor.

Stefan Sobol: How do you know you are flying a real live drone? It is possible that they extensively mapped an area, which is not hard (the flying area is restricted).

You could just be maneuvering an eyepoint around a simulated environment that is photo mapped. A hint might be the statement "At best it looks like a Google Street View image"

A large number of 'live adult cams' have been around for over 15 years. Some of the models haven't aged a day, it seems....

Mind you, I imagine very few customers spend their time contemplating the underlying technology involved, while busy spending their... money.

webber15: That first shot in this article...the sandbar...looks ideal place for Waders (British) Shorebirds (American) & Terns to breed...
Also ideal place for migratory birds to rest...
Now they have to deal with f*****g drone(s) disturbing them 😩

I really hope Cape does not unlock new locations.

Yet again...have to say drones should come under RC Aircraft regulations...

Do waders build mobile phones, or execute bitcoin trades, or make reality TV programs? No? So what are they good for?

Mind you, there is a South African recipe with chestnuts, mandarins and paprika....

Joking, joking ;-)

I like your skepticism. On the surface (or in the air even) it seems like it could be a fairly straightforward, and possibly lucrative scam to execute. Just a case of switching the footage from the adult 'live cams'. Maybe even combine the two.... Ok, I need to stop writing now.

Najinsky: @Rishi

"Manufacturing larger lenses is also slightly easier, since the same relative tolerance level can be achieved, despite a larger absolute variance."

I've seen this noted in articles on several occasions. It sounds logical and plausible to me but the subject has arisen in a forum discussion and it is being disputed.

Are there any articles you can point to that shed more light on the subject?

Thanks.

Thanks for the comments guys, appreciated.

If you fancy a foray into the forum jungle there is a small discussion going on here:

The main thread has gone a little awry, but the subthread linked to is still on pretty even keel with some interesting contributions.

Favorable Exponynt: Another random act by the child who is President

Most obvious guess is:

A) that some intelligence has surfaced about plans/attempts to use electronic devices as some form of threat.

B) that US airlines are complying with additional background check requests regarding passenger manifests, while some airlines are not, yet.

Anyone know what happens for indirect flights, for example from Thailand but with a stop in Qatar? If the device is allowed to be taken on board in Thailand, but not when re-boarding in Qatar, it could lead to confiscation, which would not be good.

Thanks, very interesting.

Just for clarity, are you able to confirm that 24 hours (non continuous) start to finish is when starting with some pre-made components such as the pre-cut glass disks, and housing components, or has the time to manufacture those from raw materials also been factored into that 24 hours?

Im not sure it matters either way, but from the interview article, Canon appeared to say it was the former, whereas this article is giving me the impression it's the latter.

In reply to:

ottonis: Apple lowering prices of the new iPad means that iPad sales must be in serious trouble.
Moreover, why are they using a CPU from yesteryear?

While it's true a lot of tablets are not getting used, there are two interesting stats to consider.

Apple have around 20-25% of the tablet market (it varies based on the sources of the stats).

Apple iPads have about 80% of the logged traffic for tablet based browsing, a touch less for streaming and gaming but still the lions share.

The only sensible conclusion to draw from those figures is that a large majority of non-Apple tablets are not being used. Or perhaps I can word it this way, Android certainly seems to be dominating Apple in the unused tablet market.

I know a fair number of Android tablet non-users, and many wanted Apple but were put off by the higher price, so the combination of price drop and higher spec machine for the entry level iPad may turn out to be quite a smart move.

On article Fujifilm X-T20 Review (291 comments in total)
In reply to:

Najinsky: Confusion central. Checking out the raw files from the X-Trans 3 cameras just doesn't support what you have been writing about these cameras.

Here's the queen of spades in the comparison scene, XT2, XT20, X100F and GR2.

http://bit.ly/2nPzf2m

The X-T2 looks great. The X-T20 is softer and the X100F is softer still.

The X100F output shows about the same resolution as the 16MP Ricoh GR 2, just uprezzed to 24MP. Clearly the old lens cant match the new sensor, it should have been upgraded for this price point. For sure, the Xtrans 3 output is nicer than Xtrans 2, and that helps a bit, but gold award, at this price, Meh!

Now the XT20 should deliver very similar results to the X-T2 and in the review you say it does, but the raw shown above is clearly softer (eg the ruby). Is it a testing error or something more serious, like the camera being prone to shutter vibration on some shots?

Note, switching from raw to the JPEG does make the XT20 match the XT2. But why is the raw so soft.

My original 12MP X100 produced wonderful images, lovely colors, contrast and sharpness, it was a joy to review the images,despite the frustration of shooting with it!

With the same lens in the 16MP X-Trans X100 models, it was clear it struggled to meet the higher demands of the sensor. The 16MP Ricoh GR out-resolved it despite being bayer sensors.

And now the same lens in the 24MP X-Trans 3 body? Yet DPR are singing its praises? Yes, X-Trans 3 pulls a little more from the lens, but it's not close to the sensors potential as shown with the X-T2.

A benefit of going to 24MP in a fixed lens camera is the ability to crop more. Fujifilm recognize By providing crop modes for convenience. But at this level of performance, cropping only throws the spotlight on the lenses shortcomings.

As a prime shooter, my concern about the X-T20 is in a similar vein, if shutter shock compromises the resolution, there goes my ability to crop. I'd happily crop the X-T2 image to 50%, but not that X-T20 raw.

Najinsky: The Gangbang Theorum...

...aka lets hit on a single camera using a whole gang from a different system.

The spin:

Fast lens comparison - Canon 85/1.2
Noise comparison - Sony A7Rii with BSI Sensor
Dynamic Range - Nikon D810 with ISO 64
Resolution - Back to Canon with the 5DS R

The obfuscated message:

Fujifilm GFX 50, combining the best of the best from Canon, Sony and Nikon, in one compact mirrorless camera body.

It's not, yet. But as with any new system, the early adopters will buy it for the things it can do, not the things it cant. And if it succeeds the system will evolve to do more. But for starters, a 1.6 equivalent over a larger frame is not too shabby.

Just one query, in the rollover equivalent images of the Japanese Doll, why does the FF image have such a nicer '3D pop' than the APS-C image?

Well, I like to make my comments multipurpose where possible, but yes joke was the primary one here. And yet... :-)

In reply to:

JT26: I used to adore apple... Just bland announcements and behind the competition now. The one thing that keeps them current is their operating system which is slicker and quicker than others.

Lol, nothing wrong with an information-free lifestyle JT. But just in case not everyone has made the switch to information-free, here's some information:

Apple dominates tablet usage, with stats such as 80% of tablet based browsing, streaming, gaming, productivity, etc and topping many polls in the tablet shoot-outs, for example:

http://www.techradar.com/news/mobile-computing/tablets/10-best-tablet-pcs-in-the-world-today-1079603

So how can they improve on already great? Entry level model, they cut the price (very welcome given the strong dollar) and gave it a bigger battery. Oh, and for good measure they threw in a better processor and display too.

Last year the Pro models got a price cut and there will be the regular refresh when the new chips are ready.

The red phone is continuation of their charity commitment. This year is 10th anniversary of iPhone, a more significant annnouncent is expected later.

Please excuse me, an Apple apologist corrupted by all that pesky information.

In reply to:

Mariano Pacifico: Highlights:
1. Kit lenses are made in Taiwan. I wonder why not in Japan? Probably cheaper labor?

2. A lens can be done from start to finish to packaging in less than 24 hours!

3. It takes 30 to 35 years to be lens Meister. It takes about 10 to 15 years to be a sushi chef another 5 years just to cook the sushi rice. That is Japanese perfection for you.

4. Technology for auto-focus speed selection is here after all, it is called nano-USM. My Canon G7x MarkII is too quick to focus for my taste. Wish they implement it in compacts and pocketables.

Good work ! Thank you.

Now on to Nikon Lens Factory ....

Remember, the 24 hours is mostly assembly of pre-made parts, which were previously made in batches, so the 24 hours is not really the total time for the entire lense, it's a little more involved than that, as shown in this video:

https://m.youtube.com/watch?v=ovxtgj4SsiI

Nikon proceeds looks pretty similar, albeit without commentary:

In reply to:

Najinsky: "without any significant loss of quality"

Says who? The saturation loss leaps out at the slightest glance. So what they are saying is they threw 35% of the color away and ended up with 35% less data.

Can't believe you guys are pedaling this trash.

Google are ruthless. The only reason they want less data on the page is because they want more Google on the page.

Yes, data size savings in serving web pages is always going to help make a case in favour. But it needs to be balanced with its function too.

A huge amount of data gets cached at various stages of delivery; proxy servers and browser caches for example, so are not continually being served from source anyway.

If we look at the images you referred to, those down the side of this page, the answer to the question who cares, would probably be DPR competition winners, who may not be happy to see a yucky desaturated version of their work being shown off under their name, or product photographers who took great care producing the original shot.

Yes, these arguments can be exaggerated, as can the data saving argument.

Perhaps a 'hidden benefit' of this could be when low quality images are the new standard, a two tier pricing structure could be introduced.

Would like like your ad served in high or standard quality sir? Click, add $2. There you go sir, high quality, just like the old days ;-)

On article Fujifilm GFX 50S added to our studio test scene (440 comments in total)
In reply to:

Najinsky: Very nice, but improvements over FF are only slight and incremental, much closer to FF than the reference camera (Phase One).

I'm waiting to see how the new Hasselblad performs on the test. Don't anticipate that much difference but the Hassy sample shots were so nice, it will be interesting to see if the monkeying around they are doing with the 14/16 bit thing allows for any improvement in the result.

Sorry, they use the word Benchmark rather than reference. In the studio comparison scene above, pull down camera selector and you will see 'Phase One IQ180 (benchmark camera)'

I always use this as my reference when looking at a new camera comparison, specifically for comparing to the banknote and the line drawing on the left of the scene.

The banknote is good for checking progressively finer detail, while the line drawing shows any moire issues and also where 'fake detail' is being created by the demosaicing process.
