On Panasonic DMC-CM1 to go on sale in UK article (152 comments in total)
In reply to:

grasscatcher: I don't think it would work in the U.S. because the market there is predicated on upgrading your phone every two years (or less!).

OTOH, there may be a market for a phone chip in, say, a GX7 or a GH4. You would need to use a bluetooth earpiece, though - you'd look pretty silly holding a GH4 up to your ear and talking into it...

This is a niche product, Panasonic is by no means expecting the same number of units as Samsung or Apple do. This doesn't mean the CM1 can't be successful in the marketplace.

te 2r: I like everyone's reaction of "But I can buy a smartphone and an RX100 for less!", missing the entire point of the pocket-able convergence of the two things. This isn't only a smartphone and a camera, it's also the thinnest 1"-sensor enthusiast compact by far.

It costs a lot, but this isn't a high volume, ultra mainstream Galaxy S5, you know? It's a super niche 1st-gen device. Personally, I'd consider it if they brought it to the US.

I doubt Panasonic has any intentions of getting into the business of dealing with mobile carriers in the US. The whole carrier game works differently in the US to most other parts of the world and most devices need a custom firmware for each carrier...not something you want to get into if you are, compared to the Samsung Galaxys and iPhones of this world, only selling very minor quantities of your device.

sderdiarian: What is the sensor size, 1/2.3"? And is it the same Sony 21MP sensor as in the Experia Z-3? If so, hopefully they've improved the camera module and processing performance.

When will we see a review? And you reeeaaaallly need to update Connect's homepage, still banner headlining reviews of superceded cellphones like the G2 and iPhone 5S. This does not help your credibility, makes it look like Amazon's walked away from this venture.

see comment above for sensor size. Given this is a US-only model I am not sure if we can slot it into the review queue but we will see what we can do .)

In reply to:

Danlo: Sensor size please?

Difficult to tell as no information was provided in the press materials. However, base ISO and image size are the same as on the Sony Xperia Z2, so there is a good chance it is the same 1/2.3-inch sensor.

cogthrob: Does this phone have manual focus? I know that's a featured that was slotted for L (from below video) but LG had it in Android 4.4.4.

Thanks!

There is no manual focus in the standard Motorola camera app, but it might be available through some 3rd party camera apps. Have a look at Camera-FV5 or Camera Awesome for example.

Felix E Klee: Lars Rehm lives in Landau? ;-)

No, not Xanadau, but Apple Maps misspells it "Landali" which is a bit of an embarrassment considering that Apple Maps has been out for years and this is no metropolis but still a town of 40K inhabitants.

did not notice and distortion but there are plenty of images in the review for you to check yourself. DxO only measured negligible distortion in their studio testing: http://connect.dpreview.com/post/6303555427/apple-iphone-6-plus-camera-review?page=8

gurmusic: My oposition is: I dont want a phablet but I want the optical stabilisation... I am going to upgrade my 5s to 6 but I will miss one of the two major improvements over 5s

give it a try, it is actually quite manageable in size once you get used to it. I put a case on it which adds more bulk but without the case it is quite nice to handle, also because it is quite thin.

Photato: Any reason why Apple is still using a 4:3 Aspect Ratio sensor in a 16:9 world?
All the pictures are shown top/botton cropped on the iPhone 16:9 screen or with side bars when zoomed out, same for HDTVs.
As for Video, most of the sensor's pixels are wasted into a 16:9 crop. Here the lens behaves more like narrower 38mm eqv.
I am scratching my head wondering about Apple's famous attention for detail. LOL

to be fair the CM1 is more of a camera with an attached phone component than a smartphone with a camera :)

The Squire: What? No 4K? At that price!?

yes, Lumia phones and Sony Xperia Z1-3 for example have a shutter button that you can half-press to lock focus.

you can do that on almost any phone but it doesn't give you the two-way control of a real shutter-button.

Samuel Dilworth: I have to ask: what is the intriguing book in the fourth picture on the first page?

It is a German book on photography from the year 1936 called "Knipse - Aber Richtig!" Loosely translated that would be "snapshooting done right" or something along those lines :)

same reason why pretty much all DSLRs use 3:2 and compact cameras 4:3...they are very well established still image aspect ratios. 16:9 is very much a video thing. Shooting still images in portrait portrait orientation with 16:9 is quite painful for example...

In reply to:

GabrielZ: The iPad Air 2 is quite an impressive upgrade, even though I was hoping for an even higher 3x res screen to take it to nearly 400 ppi. But the new laminated display with antireflective coating is a worthy improvement in its own right and seems to solve the Air's only real display drawback - the visual quality out in sunlight and under bright lights.

As for the iPad mini 3, that was a real disappointment! They shouldn't call it the mini 3 but more accurately the mini 2+. Apart from Touch ID and that optional gold finish its the same model as last year, with that sub-par colour gamut display (you can see the difference in colour quality between the mini and the Air) and inadequate performance nowadays of the A7 SoC for this application.

I run iOS 8 on an iPad 2 and it works reasonably well...granted I mostly watch video on that device. Not sure how it behaves when you do other things...

Sony smartphones do not have any optical IS, only digital. I can't see a reason why the Nexus OIS would not work in 4K mode.

In reply to:

Joel Benford: I've never seen a 493 ppi screen, I thought the "retina" was meant to be all we need.

Is 493ppi useful?

Is it regularly useful?

If it's not regularly useful, would we be better off with more battery life?

"Retina" is just Apple marketing speak. Most high-end Androids have had denser displays for quite some time.

At the moment I think 1080p is a good compromise, even for a 6-inch screen, but the higher res screens do look a touch sharper.
