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.

corkymiller46: What are their dimensions please

The 4K model is 189 x 130.5mm, but I don't know the depth, I'm afraid.

In reply to:

webrunner5: I think it is just 30fps.

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

Alphoid: I'd love to see a transcript on segments like this.

The transcript is now linked at the bottom of the page.

Given I just wrote it out to make sure the subtitles/close caption are correct, I might be able to do this.

hbjarna: "Hands on" usually does not mean just holding the lens in your hands. Try mounting it on a camera and take some pictures.

MasterWayne. I'm part of the team running around Photokina, shooting pics and conducting interviews. We're not taking part in any formal events but if you see and recognise one of us, as we race between meetings, please say hello.

That would be a samples gallery. In this instance, it'd be a gallery of images of the inside of a meeting room.

It was challenging enough to actually get hold of the lenses - they're in a glass case most of the time.

gameshoes3003: Person ignorant of the A-mount here. From what I'm understanding, these A-mount cameras have a translucent mirror, right? Does that mean that there is less light reaching the sensor? Do you have to start cranking up the ISO earlier relative to other cameras?

They have semi_transparent mirrors which yes, direct a proportion of light away from the imaging sensor to the focus module.

But no, you don't have to adjust ISO. The diverted light is factored-in when calculating the ISO settings, so you still get the expected image brightness from any given exposure (but with more noise, because less light made it to the sensor).

In reply to:

Interestingness: As to the 12 fps, from the Sony release itself....

Furthermore, when “Continuous Shooting: Hi+” is selected, focus will be fixed at the first frame shot when Hybrid Phase Detection AF is active at aperture settings of F9 or higher, or when Hybrid Phase Detection AF is not active at aperture settings of F4 or higher

The press conference included a 12 fps sequence shot with AF and the text on the slide is pretty unambiguous.

On article Upwardly mobile: Sony a6300 Review (2163 comments in total)
In reply to:

Ryan Rosenberg: I'm a bit shocked that this got a gold rating given the video overheating issue. This is a very real issue -- a large number of people get perhaps 10-20 minutes of video and then the camera overheats. The only mention in this whole review was "we didn't encounter it". Fair enough, but the overwhelming data is that this issue is for real. So perhaps the testing was poorly done. I think overheating should have at least been noted on the summary page as a potential issue. And I believe the video rating should have taken a hit for this.

The rest of the review is reasonable, just this part seems to me an egregious oversight.

It's listed as a Con and there's also the following line in the conclusion:

'With the latest firmware, the camera appears able to shoot 4K for longer without overheating. It can capture 4K video for up to 29:59, but this number can drop in warm ambient conditions. Whether you notice this will depend on your shooting style.'

On article What is equivalence and why should I care? (2220 comments in total)
In reply to:

richshep: If I blank off a full frame sensor in a, say, Sony R7, to 5mm by 8mm, does that mean it will suddenly become a less efficient sensor and produce more noise? This total light stuff is total nonsense.

No, and no one is suggesting it would change the behaviour of the sensor.

However, you would get the same much narrower field of view that a natively 5 x 8mm sensor would give, meaning you'd have to move a long way back to shoot the same framing. This would also mean that you'd get much greater depth of field.

And, create a print at the same size as from your full frame image and the image will appear noisier. This is because most of the noise you encounter isn't from the sensor, it's from the amount of light you've captured.

Capture the same amount of light per sq mm over fewer sq mm and you capture less light. The less light you capture, the more apparent the inherent randomness of light becomes.

By all means test it. You'll find the noise of your cropped sensor is just as bad as from a compact camera with the same size sensor.

On article Canon EOS M5: What you need to know (543 comments in total)
In reply to:

Nobby2016: how is the cipa battery life calculated?

is every shot with flash or a percentage of shots with flash?

edit:

i found it.
flash is used for every second picture at full power.

Most people's real-world usage sees them get more shots per charge than the CIPA numbers, just as most drivers end up getting fewer miles out of each gallon of fuel than the official figures suggest.

However, the numbers tend to be comparable between cameras (so if you get 500 shots out of a 300 shot-per-charge rated camera, you'll get nearer to 1000 out of a model rated at 600 shots-per-charge).

In reply to:

Nick Brundle - Photography: The implementation of this touchscreen is most impressive (if it works that is). It will be great to use the rear touchscreen to position focus, and use as a touchpad to move the focus point while using the EVF.
Look forward to the testing and the review.

Tommi K1 - every Panasonic I've used with focus touchpad has let you choose between absolute and relative movements.

The M5 offers both options and, lets you select whether the whole screen or just regions of it are active so that there's no risk of nose focus.

On article Special K? Pentax K-1 Review (2663 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!

You can't just *invoke* Rishi. He wasn't one of the primary reviewers of this camera and it's DPReview's score, not any one individual's.

Looking at the Raw image quality scores, it seems the K-1 scores higher than the 5D IV and a fraction below the D810. I'm not clear how that's inconsisten with what DxO has said.

The K-1 got a good score and I think the review makes clear that its image quality, especially in Raw, is excellent.

dotyman: Hey DPR–do you think you'll have the full review of the M5 done by Monday?

Not without a camera. No.

In reply to:

thxbb12: How come the comparaison table (in page 1) doesn't feature the Fuji X-T10? It would certainly be a strong contender!

Because a lot of the appeal of the of the EOS M5 comes from how easy it is to capture good video. I only had room for two comparison cameras so I went with two other strong stills/video models.

PKDanny: Where's Phil Askey now? He's quiet. He didn't review any. I knew him owner DPREVIEW since I joined DPR 2006.

The site was acquired by [Amazon](https://www.dpreview.com/articles/1690663587/amazonacquiresdpreview) just over nine years ago but Phil continued to run the site for several years after that.

We haven't received that information from Canon. We'll ask.

osan: I think Dpreview has a "thing" with new 18-150mm zoom lens. On a page which I can't precisely remember where, it was converted as 29-149mm equivalent and on this page it's listed as 15-150mm§. It's just a trivia but the staff must have worked under pressure to meet the deadline for publishing the preview ;)))

Ah, a database typo! That should now be fixed. Thanks.

In reply to:

downwind4final: I like the IBIS and form. Add 4k and I'll start being interested.

T3: I don't have notes about whether there's a different video crop for the IS on and off modes but digital IS is usually offered by capturing a larger-than-1080 region then selecting a 1080 frame out of that footage and moving the frame as the camera's shaken. (Hence why you usually don't get digital IS in 4K mode - because most cameras can't shoot a greater than 4K region to give that extra margin around the edges).
