yortuk: Panasonic also does pretty well in my experience. A couple years ago I fell into a creek with my GX8 with 12-35 2.8 lens, and landed on top of it in about 10 inches of water, and even bounced it off a couple rocks on the way down, and I never had any problems apart from having to spend a few minutes looking for my lens cap and a couple dings on the body and lens barrel.

Sorry if my phrasing was unclear, but I meant it as "Panasonic is another brand that does well".

Saurat: Where are all the MFT trolls who constantly talk about the systems "tiny, uaeless sensor" ? They've gone very quiet.

Entropy, if you pay closer attention you can see they're switching back and forth between exposure matched and DOF matched. They even label it in big bold letters in every shot. How could you miss that?

mosswings: Very cool, but two comments:

1. Numerical aperture of 0.2: this is roughly equivalent to an f-number of 2.5.
2. Efficiency of 20% - if I understand this right, only 20% of the incident light is transmitted, a light loss of 2.1 stops. Makes sense - this is effectively a thin metal disk with slots at various spacings and widths. It is far less transparent than a glass element - even many glass elements.

There are applications for this technology, but it does not appear to be in low-light capable imaging systems - that is, consumer cameras - at this time.

You have a remarkably limited imagination for possibilities this presents.

You just need a bigger sensor size, or a large array of small ones. A device the size of a cell phone covered in these could have an effective sensor size five times that of a full frame camera, and no doubt will eventually be cheaper.

In reply to:

David Bo: The thickness is on the order of the wavelength. That's around 0,47 micrometers or 0,00047 mm (200 times thinner than a human hair) which would be a major disadvantage when constructinger larger lenses suitable for larger sensors (read impossible to make).

It's exciting news but right now not usable in real life.

If they're cheap enough you could have large arrays of them with a much larger effective sensor size and higher resolution than anything you can buy today.

With all the software-based enhancements happening these days (image stacking, distortion correction, red-eye removal, artificial bokeh, etc), I wonder how difficult it would be to correct the donut bokeh in-camera.

In reply to:

Majkyman: Colors on iPhone seems a lot better to me, but for portrait mode and detail I think Pixel is a clear winner.

I think the color looks exaggerated and artificial in a lot of the iPhone shots. Some look almost posterized. It can be a nice effect, but I don't want that to be the default.

In reply to:

JoeWall: And who will watch 8K videos? Nobody who uses a m43 camera has an 8K monitor

Tommi, the big difference with the Google Pixel is the automatic processing it does to combine the frames to get a higher quality image than is possible with a single frame. This is possible in other cameras with post-processing or even in-camera options, but requires the user to make those decisions and is not a seamless, automatic process. The point is that computer processing can really do a lot to increase the image quality that's possible with a given sensor, and it's becoming more automated.

RPJG, it's not just the battery capacity, but also the efficiency of the sensor and processing. That's where a lot of the advances have been coming lately, particularly with Sony's stacked sensors. Also, with live view displays we're doing a certain amount of continuous readout already.

That's already happened in phone cameras -- the Google Pixel camera is constantly recording by default and then just combines a few frames when you press the shutter and saves it as an HDR image. It has its limitations, but the results are usually better than I would have thought possible for such a small sensor. Applying the same approach with a m4/3 sensor could be really impressive.

Lan: Is anyone else getting bored of this "oh look how great our product is, it's selling out" malarkey? As with any other manufacturer they control the amount of inventory available at launch, so it's really easy to engineer these "shortages".

I do wish companies would learn from the positive things that Apple brought to the marketplace, not the annoyances like the fake "shortages".

Olympus, Nikon, Sony, and Fuji have all introduced cameras in the last few months that arguably are competing for the same customers. How long should Panasonic hold off while potential customers are wooed by the shiny new stuff from the others?

Not everyone can rest on their laurels the way Canon can. And arguably many of their customers put more importance on lens selection, build quality, usability, and shot-to-shot performance than bleeding edge technology. Panasonic and micro 4/3 need to stay ahead of the curve with new innovation to keep people interested.

Not that long ago Panasonic had a big intro for their GX8 camera and it was a flop. I bought one at intro and I quite like it, but they've been on fire sale pretty much ever since, so I can't imagine they've made much money on that one.

So clearly they don't have a crystal ball for this stuff. And while I expect the GH line is more predictable, you also have to consider that there have been recent supply problems for lots of Japanese manufacturers due to uncontrollable things like earthquakes. So which is better, delay intro until supply is full, while competitors are introducing new products, or get your product to market while it's still relevant?

Your view of this is overly simplistic and cynical.

In reply to:

mpgxsvcd: I thought the GH4 had auto ISO in manual mode? Does the GH5 have Auto ISO in manual mode plus exposure compensation?

@Miki, the specs say the GH5 does 4K with no crop. Every other mirrorless or DSLR that I'm aware of uses a significant crop. The result is that for 4K video the GH5 has effectively as large a sensor as those other larger format cameras.

In reply to:

Miki Nemeth: A long awaited feature (still ?) missing from Panasonic cameras is MF Assist while recording. I wonder, if this camera, first in Panasonic's life, is supporting that damn function at last? I have an FZ2000, and it's excellent, but terribly infuriating that MF Assist doesn't work, when I start recording. MF Assist along with the excellent focus peaking WHILE recording would be so great. It's great that the hilarious 4K crop was gone. Unfortunately, I still have a crazy 36mm 4K crop on my FZ2000. With all these bells-and-whistles the GH5 should have included an APS-C sensor, just like JVC did with the LS300. That would have been a Sony/Canon killer. This way the GH5 is just a very strong competitor with a hell lot of limitations. Low-light wedding videographers with their brutal A7Sii's, will not get very enthusiastic, I guess, but a GH5 with an APS-C 12M 4K (low-light) optimized sensor, that would have been a king. As Andrew Reid would write, Panasonic again missed the opportunity.

And which lenses would you propose to use with your imaginary APS-C GH5?

SteveY80: I'm not sure anyone else will care, but to me it's a bit of a shame that the 45-175mm hasn't been updated too. It's a great little lens and doesn't extend when zooming - it must be one of the few lenses that doesn't support dual IS.

I wonder if there'll be some bargain 35-100 f/2.8 mk1s appearing on the used market any time soon?

Also Panasonic promised a dual-IS firmware upgrade for the 45-175 that's now going on two years late. I bought the lens specifically with that feature in mind, so it's very frustrating that they seem to have forgotten about it.

(unknown member): For a phone, those are pretty darned good! If my phone took pictures like that I would be very happy. One question though - why are the skateboard's wheels square? Is that rolling shutter in action or some other anomoly?

They actually look that way in person. It's an interesting optical illusion. You can get a better look at https://sharkwheel.com/

On article Google's Pixel phones: What you need to know (122 comments in total)
In reply to:

DualSystemGuy: Some additional less obvious details:

- Storage is UFS 2.0
- 192kHz/24bit Audio
- Uses 18W charging through a USB- C power specification rather than Qualcomm quick charge 3.0
- Google optimized its HDR algorithm to run on the SD 821 Hexagon 680 DSP (instead of the CPU), using vector instructions to handle HDR processing with no shutter lag. This also saves battery life.
- The sensors just below the ear piece are for ambient light and proximity
- The free Google Photo storage includes original quality 4K video
- The highly impressive electronic video stabilization does not work with 4K (1080P/60 max)
- Even the Pixel's front/selfie camera uses a larger sensor than the iPhone 7 Plus' telephoto camera
- It has a notification LED
- Water resistance is IP53

I'm pretty sure that's 192 kbits per second data rate, not audio frequency.

edit: also, 20kHz is pretty much the max audible frequency, and people my age it's more like 16kHz.

newe: In reading numerous Android forums there SEEMS to be a lot of hate towards these new phones. Many think this is Google wanting to be Apple. Price is insane. Some have posted Canadian prices are $1,100. Who in their right mind would pay that for a phone with no SD card? I'm wondering if this will turn out to be a bad move for Google pricing this way. I bet OnePlus is happy!

I've had the Nexus 4 and 5 and loved them...won't be getting the new Google phones, the price/value proposition is not there for me in the least.

@tkbslc, I'm not aware of any prepaid plan that provides comparable service for $20/month. $10/GB for data is expensive, but I've never used that much data on mobile.

@GodSpeaks, do you live in the US? With T-Mobile I paid $40/month for unlimited everything (but slower data after 5GB), and now pay $50/month which includes service in Canada. The Project Fi service will be between $20-$30/month based on my current data usage, but more expensive when visiting Canada, i.e. $0.20/minute for calls not using a wifi connection, but with free texting, and mobile data is the same as the US. Also calls from US to Canada are free.

Mobile data on Project Fi is $10/GB, so it's not as good for people who use a lot of mobile data, but I get most of my data on wifi so it's not an issue for me. Also, the whole point of Project Fi is that it seamlessly transitions to wifi whenever it can and has a large network of wifi hotspots in place.

I know lots of people here who pay upwards of $70/month. And these rates are actually much better than my brother in Canada pays. He was looking into visiting the US to sign up for the $50 plan I have so he could use it in Canada.
