justmeMN: Watching this video made me thirsty. :-)

I'm kidding, I quite like Kolsch, it just becomes a little overwhelming, after hours at Photokina.

That said, I utterly disagree with regards English beer. It could be because it's what I grew up with but there are some British beers that I'd drink in preference to just about any Belgian or German beer, lovely though those can be. Slight problem that you have to drink it on cask, as close to the brewery as is practical.

Rhawi Dantas: Ricoh, if you are listening bring a GR with an 35mm equiv. lens. While at it slap a 24mp sensor and we are done.

I volunteer as tribute for testing. (hard job but someone has to do it.´).

I suggested 40mm equiv but would be happy with 35. The implication was that if there was enough apparent demand, they'd consider making one.

Whereas it just reminds me how glad I am that I won't have to drink kölsch for another two years. ;)

I think he's asking what you meant (presumably the middle section about pre-show orientation). I too am a bit baffled.

Smitty1: Please more lenses, many more moderns lenses. And Sigma needs to get onboard too. Especially on the telephoto side where Pentax is rather thin. Pentax seems to be designing more primes but they don't provide any specific details beyond the vague roadmap.

I don't think many people in the Canikony camps want to trawl ebay or the like for old F and FA lenses. I think most would rather have a new design (reduced CA, in-lens motor, and perhaps weather sealing) with full support behind it.

I've just added in links to the company's latest lens roadmaps for both D FA and 645 lenses, so you can see what they've promised.

Mariano Pacifico: Nikon DL 18-50 Premium Camera was introduced February 2016. To this day not a shadow of its release. Was it a joke or what? Will it be released on Halloween? Is Nikon going to make a praise release? I am tired of waiting.

I'm not sure how this pertains to Ricoh. Nikon warned in April that they weren't going to hit their June launch date and have offered no further update. Several sites quote the company as saying they are delayed 'indefinitely,' so I wouldn't hold your breath.

Najinsky: 4:54 - Richard trying to say aluminum after two sips of lager ;-)

Yeah, but that was also frequently true during my chemistry degree and I'm pretty sure I could say 'aluminium' back then.

I suspect I was trying to decide whether to use the pronunciation I've used most of my life or the pronunciation a lot of our readers will be used to.

And, by trying to think about two things at once, I just ended up stumbling over the word altogether.

Photokina takes place in Cologne, so it's kölsch all round, whether you like it or not. Carey managed to plead extenuating circumstances, meaning that he was allowed a pilsner.

Richard Franiec: Drinking on the job seems appealing and highly liberating as this video shows.
Even Canon can be forgiven for being 2 years late to the party with M5.
Well, if you work 24/7, you deserve libation from time to time in order to clear the head LOL.

I like to think of it less as 'drinking on the job' and more 'continuing to work when we really should be drinking.'

On article Special K? Pentax K-1 Review (2669 comments in total)
In reply to:

Class A: The K-1's sensor was measured by DxOMark. They call it a "Full-frame marvel" and it currently sits at 4th position in the overall ranking, beating cameras costing almost twice as much.

In all measurements the K-1 beats the D800 and even D810 at the same ISO setting. Only because the D810 has a lower ISO setting (64 rather than 100), it receives a higher dynamic range score.

A (real) lower ISO setting is of course a legitimate advantage (the Pentax K-5(II) put a lot of APS-C competitors behind it with its ISO 80 setting), but it is still impressive what Pentax manages to get out of that sensor for the supported ISO range.

The K-1 is even very close in performance to the leading Sony models with their high-end 42MP sensor. Another testimony to the fact that the Pentax engineers did a marvellous job!

Hi Class A. Yes, it's hard to strike a balance - especially when the accusations being made question your personal probity.

I'm not sure that I agree that 'Low Light/High ISO' implies that it's solely a measure of sensor performances but I'll bear it in mind as we rework the scoring system.

We do give all cameras the same amount of exposure so that the Raw files are comparable. Not quite the same as the saturatuon-based method, but still a level playing field.

KrisAK: So, were review kits not distributed prior to the announcement? I can't seem to find any "shooting experience" reviews, anywhere, let alone samples.

No. All the cameras were too far from production for us to be allowed to shoot with them.

It's fairly rare for reviewable cameras to be available before announcement.

Angrymagpie: Is the show over?
Does this mean that we are not getting an update for the X100 series?

I'm afraid it does appear to mean that.

On article What is equivalence and why should I care? (2222 comments in total)
In reply to:

dslater38: "And, while we're summing these things up: different formats cannot have a 'depth of field advantage' over another."

I disagree with this statement. While what you say is true about diffraction, If I wanted to get the same shallow DoF on a 1" sensor that I get on a FF with an 85 f/1.2 @ 1.2, I'd need a lens that was f/0.6. Good luck creating such a lens with the same optical quality as the 85 f/1.2

When I wrote that sentence, I was thinking more of the opposite case, where people believe that a smaller sensor gives you more depth of field. It does, but there's nothing to stop a larger sensor matching it by stopping down.

Equally, it's the availability of lenses that defines how shallow the available depth of field can get. For instance, medium format sensors offer the opportunity for shallower depth of field than full frame but only if suitably bright lenses are available.

In reply to:

rsilverst: "because the more light you capture, the less noisy your image, this is key to why large sensors generally give better image quality than small ones."

I don't understand this statement. I would think of noise as being based on amount of light incident on the sensor pixel-by-pixel, and that the reason a full-frame sensor is less noisy is because it has larger pixels (for a given total pixel count), so each pixel captures more photons for a given light level. But this article states that the overall cone over which light is captured would be related to the noise level. My understanding (perhaps incorrect) of optics is that each "point" in the scene would project light onto a single "point" on the sensor, so a wider circle should not affect amount of incident light in a central point.

I would think a 10MP APS-C camera should have the same noise performance as a 24MP Full-Frame, since they would have the same size pixels (if all other electronics in and behind the sensor were identical).

So look at it this way:

If two sensors have the same **size** pixels, then you get the same noise per pixel but the larger sensor has more pixels. Scale them to the same size to view or print and the larger sensor looks cleaner (because of the way the signal and noise combine, across multiple pixels).

If two sensors have the same **number** of pixels, then you get more signal at each pixel, so the larger sensor looks cleaner.

Since you get essentially the same result, regardless of pixel size, once you view at the same scale, then the underlying issue probably isn't directly one of pixel size. For a more nuanced answer, there's [more detail here](https://www.dpreview.com/articles/5365920428/the-effect-of-pixel-and-sensor-sizes-on-noise).

Class A: DxO only measures Raw performance, whereas our low light/high ISO score covers both Raw and JPEG, so two cameras with the same Raw IQ can still end up getting different scores in the low light/high ISO category.

Secondly, DxO's labelling of saturation-derived ISO as 'measured' ISO is potentially misleading. It's not the case that DxO states the 'correct' ISO or the ISO figure you'd get if you tested them properly. They state the figure you get if you test them in a completely different (Raw-based) manner.

DxO's 'measured' vs 'manufacturer ISO' graph gives an insight into the highlight headroom/shadow noise balance being struck by each camera's metering and JPEG systems. It's not especially relevant to this discussion.

eit412608: Wasn't this already covered back in April at NAB.
Is there anything new?

There's been a firmware update adding false colour and DNxHR. However this is story isn't saying they're new, just that they're the thing I thought would be most interesting to our readers on the Blackmagic stand.

webrunner5: I think it is just 30fps.

Yes, it's up to 4K/30p.
