m87501: if Sony would re-design their silly menus, less demand for this.

PazinBoize - We always try to make clear that between button customization and the Fn menu, you rarely need to use the menus, once you've configured the camera. But, if you do, it can be extremely difficult to find the setting you're after (even with the improved signposting of the latest iteration).

JensR: > and give film-like latitude in the highlights

Not this again. At identical format size, modern digital sensors already match the latitude of most colour negative films. It is just that digital does better with shadows and negative film does better with highlights.
*Any statement about "latitude" that discusses only ONE end of the scale is probably designed to mislead the reader or written by someone who is misled themselves.*
Also, if latitude were the most important thing in the world, slide film would never have been a thing.
That said, if their device is as good as digital in the shadows and as good as negative film in the highlights, THEN we are talking.

The point is that current digital has an abrupt cut-off in the highlights, giving little to no margin for error. Negative film had a roll-off that gave a greater degree of recoverability. That's not the whole story of the differences between film and digital, but it is one aspect of the differences.

In this instance, since the sensor has low enough noise to count individual photons, the implication is that it does exactly what you're hoping for: essentially perfect performance in the shadows **and** greater latitude for overexposure.

chaos215bar2: Never? *Never*?

If you're going to lead with a claim that a certain technology or capability will never, ever, in all of time, make it into consumer devices, you need to at least make it immediately apparent there's some basis to the claim. The title and introduction read like clickbait, making an extremely bold claim without backing it up in any way. Looks like an interesting article, but if this is way you're going to introduce it, how do I know the rest isn't going to be just as devoid of meaningful information?

The article doesn't say it's certain that they will never appear on cameras, just that they "*may* never," ie: it's possible that they won't be used for photography.

As Professor Fossum points out, the existing technology is very good (and is likely to be still better in the roughly ten years he expects QIS to take to get to market), so it's not guaranteed.

jwhig: How could the sample photo no 6 have been shot at f/1.4 using a f/2.8 lens?

Hmm, I'll have to check the EXIF on that one.

Alphaloki: I am not a Pentax owner, but I am pretty impressed that they're offering to upgrade first version users to the newest hardware at a significant discount. Bravo Pentax. The next time I'm shopping for new gear, I will definitely look at what Pentax is offering just because it seems they care about owners of legacy hardware. As the tools become more quickly upgraded with newer tools, it's refreshing to see a company that thinks about their user base from the past. I would be shocked if Canon offered to upgrade my one generation old hardware at a discount. Pentax wins that round for sure...

£450 in the UK, €500 in the rest of Europe, with both reporting the same timeframe.

PentUp: As we understand it, there will be upgrade options in most markets, it's just that our primary contact is with Ricoh North America, so we haven't yet got details for other regions yet.

Albert Valentino: Excellent news. I bet the marketing boys a Sony are scratching their head wondering why anyone would not simply keep working towards planned obsolescence

Albert Valentino - I'd not seen that theory. If true, it might explain why Sony doesn't assemble its images in-camera. It sounds like I should remind myself of what Panasonic is doing.

Once Hasselblad had announced its system (I forget when that was), it would be hard to satisfy the "non-obvious" criteria for getting a patent, but its possible Ricoh has some wily patent people able to identify some aspect of the in-camera image processing that no one had done before.

Arguably Olympus beat them to it with the E-M5 II. Its process takes 8 shots: canceling-out the Bayer pattern with the first four then offsetting by half a pixel in each dimension and doing it again, but the idea is the same.

I think we said somewhere in our review that we wished they'd stop after four shots to get a better [non-demosaiced] 16MP image, rather than trying to generate more, which is what Ricoh does.

Smitty1: "Almost exactly a year after its predecessor's introduction, Ricoh is debuting the Pentax K-1 Mark II."

I could be having a moment, but wouldn't that be two years? K-1 was announced officially in Feb of 2016.

Perhaps a bit of both. ;)

liopleurodon: This almost makes me wish I hadn't just invested so heavily in Sony's e-mount. The X-H1 looks like an ideal camera for me offering a few advantages over my a6500 and adding IBIS for handheld video. I dismissed the XT-2 because I didn't see any stabilized primes and without IBIS video would look terrible handheld. X-H1 solves that nicely. Better zoom selection too, though I love the selection of primes on E-mount (and they all have a 49mm filter thread so i only need to carry one filter set). The final test though will be to see if Fuji's AF can keep up with the a6500's which is outstanding. Is there a way to adapt Canon glass to Fuji with PDAF?

XVOYAGERX - It could be worse: I just fact-checked a date and somehow failed to notice that February 2016 was *two* years ago, not just one.

I can't even ascribe my error to age.

I hope.

Embarrassingly I went back and checked, yet somehow didn't register that it's 2018 already. I must be in denial or something.

entoman: Some really nice features emerging here.

If it's true that pixel shift will now allow handheld hi-res photos without the usual pixel-shift artefacts, then that's a very worthwhile advance. It will be very interesting to see how well this works in practice.

The ability to control moire via a switchable AA filter simulator also makes life a lot easier for those who want to shoot fabric, feathers and fur, or architecture, but who also need very sharp hi-res results.

None of this is likely to persuade Canon, Nikon or Sony users to switch systems, but it's great news for Pentax users.

It depends what you mean by "the usual pixel-shift artefacts."

It still requires multiple shots so will always be battling against any movement that occurs between those frames.

XVOYAGERX - I think the D5500 has a mic socket, not one for headphones.

On article Sony a7R Mark III review (1226 comments in total)
In reply to:

JagK: Folks this may b e a silly Q but better to ask than keep mulling it over.

If I have a 16-35 G master lens and use it with the a7RIII in normal mode plus turn on the crop mode when required, do I get a lens that can cover 16 - 52mm, granted after 35 mm I will be getting only 19 MP with crop mode caveats.

Does it make sense or am I missing something, this should work for any FF lens correct ?

You essentially get a 16-35mm F2.8 and a 22.5-52.5mm [F4.2 equivalent](http://bit.ly/equivap) lens, since in crop mode you're essentially using a 19MP APS-C camera.

In other words, although you gain the reach of a 52.5mm lens, your depth-of-field and noise performance are more directly comparable to a 52.5mm F4.2 on full frame. You don't need to change any exposure settings, though, since the exposure system is designed to work at any sensor size.

PaulSnowcat: Yet another ML camera that obtains (FINALLY!!!) normal good DSLR like ergonomics! Thank gods for those camera makers had finally understood that that false "compactness" is nothing worth doing. Way to go! NOW ML cameras are finally starting to become comfortable and useful.

lakkot - I doubt those two figures are being calculated in a consistent manner: all our tests show the X-T2/X-T20 etc being only a fraction behind the D5600 (which is one of the best APS-C chips in terms of DR).

[Bill Claff](http://www.photonstophotos.net/Charts/PDR.htm), one of the only people to produce DR numbers for X-Trans as well as Bayer uses a higher noise threshold than DxO, lowering all his numbers. He measures the X-T2 at 10.0EV and the E-M1 II at 9.82. (With D5500 at 10.67 and a6500 at 10.31).

In reply to:

Gaëtan Lehmann: I've been wondering why there are so many bad comments about the loss of the exposure compensation dial.
I was assuming that the EC could be assigned to one of the front or rear dial, like it is possible to do on most dslr or mirorless camera.
In my opinion that would be a much better option than the EC dial of the xt2, because:
* it is too stiff and not easily accessible enough to be used (easily) with the thumb;
* it is not stiff enough to be sure that it won't be bumped when carrying the camera;
* it clicks way too much to be practical during video recording.

But after a quick search in the gfx50 owner manual, it doesn't seem to be possible assign the EC to one of the dial. Did I miss something?
If that's actually not possible, I understand that many are upset by the loss of the EC dial!

You can, at least, set a button (including a press of the rear dial) to act as exposure comp and then configure it to act as a toggle. That way the dial of your choice controls Exposure Comp until you press the button again.

grayhound_lxii: Some "special" 55-250mm f3.5-4.8 lens used in the beginning of the video or just author´s mistake...:-)

Frustratingly I stopped to look up the aperture range but forgot that I was also meant to be checking the zoom range.

Even more frustratingly, there's no sensible way of changing it.

In reply to:

ArmandvdMerwe: Does a combination of IBIS with stabilized lens gives much better results than IBIS with non stabilized lens?

Depending on which lens you use, the body passes responsibility for some types of movement to the lens. This should give the best results it can give but Fujifilm says the most effective IS comes with the unstabilized 35mm F1.4R.

Michael1000: Excellent article, Richard. I've seen a number of articles about what gimbals can do for you, and even some on tips, but none that I have seen chronicle the experience of starting from scratch. It was good to hear what that experience is really like. It is much harder than I thought.

Totally worth it, though.

LightBug: $1900 for APSC? Mirrorless cams are being updated at a fast pace. I wouldn’t feel good if I bought XT2 at full price last year now that it’s going to be on clearance soon.

Why would the X-T2 go on clearance just because a new model it introduced above it?

Did you criticise the 7D Mark II for being $1800, out of interest? Or the Arri Alexa? That's pretty pricey.
