On Sony Xperia Z2 camera review post (37 comments in total)
In reply to:

ageha: The phone will be obsolete in a few days.

for the past couple of years or so Sony has been replacing its top-of-the-line model every 6 months. However, that does not mean the previous model is not available for purchase anymore. You'll be able to buy a Z2 for quite some time. Equally, whatever gets announced at IFA most likely won't be available in the shops straightaway.

grasscatcher: I thought HTC abandoned the 4MP low-light camera concept...?

no, it's still alive and kicking in their top-end model.

uRebel Rob: This app (Google Camera) is not comparable with my android phone (Galaxy S3), and it's now an iPhone app. Hmm, I wonder why I can't use it, and which android devices can and cannot use it? (About time to upgrade my phone...)

Otherwise Sphere might be an alternative that only requires Android 4.1: https://play.google.com/store/apps/details?id=com.sphere

According to the App Store description the latest version of Google Camera requires Android 4.4 which presumably you have not running on the S3. Not sure if Samsung has made 4.4. available for the S3.

Yudi Hilmawan: Next time it would be much better if you just can show us image comparison tools like comparometer from the imaging resource other than this kind of review.
I'm really disappointed with your review because even some other non photography related site can provide us with more better and detailed review.

can you specify where we find those great reviews from non-camera people? Just so I can have a look.

In reply to:

Toshik: Why would cameras need to crank up iso while using flash? Flash helps to illuminate the subject and therefore lower iso as there is more light.

part of the problem is that most smartphones don't have real flash units but tiny LEDs which do not nearly produce the illumination of a Xenon flash.

thx1138: Crazy generous score. The photo IQ is simply second rate at any thing other than viewing it on the phone itself. I'm sure it's a relative score and only compared to other phones but the score is crazy. I reckon DxO would rate this better than a 5D III sensor.

pixel-level image quality is one component of the score but there a other things the X2 is pretty good at, that's how we get to this score.

ukkisavosta: Thanks for the interesting review. Might I suggest one additional but very crucial item to your testing scenarios: camera lens scratch resistance.

A good camera is useless on a phone, if the lens scratches easily, and my experience with Sony isn't exactly rewarding in this sense.

I recently upgraded my trusty old Nokia N8 to a Sony Xperia SP, and after a couple months of light use (with the phone protected by a fleece-lined case) the camera lens is full of microscopic scratches that have rendered the camera basically useless -- all shots are soft with an ugly glow and the camera struggles to AF.

I've handled the phone very carefully and it is still in like-new condition, except for the lens, which is obviously made of some sub-par glass (or plastic even!). My N8's lens was scratch-free after 3 years of hard use.

I like Sony's products, and I've been happy with my A7 and NEX-C3 cameras, but the Xperia SP has definitely been a disappointment in this respect.

well, it's worth a try I would say!

Personally I have not had any problems of this kind with the phones I have tested and I have a feeling that the manufacturers would not be too happy about me deliberately scratching their test units. However, if it happened during normal use in the testing process I would certainly mention that in the review.

dbo: "...only 1080p.."
ONLY????
Cmon, it's a cell phone. Who does really want and/or need 4k in a cell phone?

are you talking about the special mode output at 1080p? Yes, that is indeed a small image size for a smartphone in 2014, especially a high-end unit.

bartas: i own rooted (admin privileges) samsung s4 mini and i'm happy user of it. but thinking about the next generations of samsung phones with knox protection and filled up with useless crapware that you actually cannot remove without admin rights makes me really sick and away from new android devices

there are plenty of Android devices without any bloatware. The latest generation Motorola devices for example run pretty much vanilla Android and of course there are Google's Nexus devices.

Charlie boots: Ultimately it will be the software that counts. Spreadsheets and word processors drove the sales of the first PC's. Visicalc, Lotus123, Excel, Word etc. today hardware is becoming a commodity and thus again the sales will go to those with the best software and ecosystem. If all things are then equal it will come down to price and consumer mindshare. Samsung is still lacking on the software side.

What software specifically do you think is Android lacking?

Jogger: I never understood the appeal of metal phones. Mine is dropped regularly and i toss it around.. i just need it to work. Plastic is far, far better in the case of phones.

Most iPhone users use some sort of case ($50 for a piece of injected plastic)... thats part of the appeal of the iPhone.

I know there are 50$ cases, I just don't buy those.

In reply to:

Bryan Biggers: Not sure what the point is about the size of the sensor, are they saying it is too many pixels or not enough or what? The Galaxy Note 3 has a 13 Mp sensor for example, and that phone is due to be replaced soon. The S5 has a 16 Mp sensor, so 12 is certainly not high count by today's standards.

size does not mean megapixels but actual sensor areas. A bigger sensor tends to deliver better image quality than a small one.

HowaboutRAW: Okay, will it shoot raw?

Can I slide my fingernail under the back plate to remove it and then easily swap the battery?

And yes I realize the announcement is thin on exact specifications.

seems the battery is removable

definitely no raw, front and frame are metal, back is plastic as far as I can tell.

HaroldC3: When they say metal body do they mean metal trim? When I think metal body I think the whole thing.

It shoots 4k video yet it only has a 720p screen. I guess as long as it can output 4k then that's okay.

well, you'll need a 4K-screen to make use of that video, although all smartphone 4K video I have seen so far is so heavily compressed that there is really no point in shooting 4k over 1080p.

50-dollar cases? I'd say the ones I buy are typically between 4 and 6 $ :)

On EyeEm update for iOS comes with EyeZoom post (4 comments in total)
In reply to:

Peiasdf: I don't get photo sharing platforms. You upload picture and link to Facebook. Might just upload to FB and be done with it.

Apps like EyeEm and Instagram are massive social networks in themselves. It would be interesting to know what proportion of images is shared to FB but my guess is it's rather small. It also appears FB is making it rather difficult to share EyeEm pictures...because they want users to use their own Instagram...

In reply to:

Jogger: Is the HTC actually allowing selective focus?

It seems like its just capturing depth info at the pixel level and applying fake digital blur based on that how far that pixel is from what is in focus. In this case, its not refocusing at all... its more like digital blurring based on depth information.

No, it doesn't work any better than the pure software solutions from Nokia Or Sony, for example. Its advantage is that it takes the image in one shot and doesn't need a series like the aforementioned. I tested it quite comprehensively in the linked review.
