The iPad Air Review
by Anand Lal Shimpi on October 29, 2013 9:00 PM ESTCamera
Front and rear facing cameras are necessary features on all modern, premium tablets. The usage model for a rear facing camera on a tablet is hopefully not as a primary image capture device but rather a convenient one. The idea being that if you’re on location somewhere using the iPad for work or play and need to quickly grab an image, having a decent rear facing camera can come in handy rather than having to put away your tablet, pull out your phone and then switch back afterwards.
Apple has improved its iPad imaging systems almost every single generation. That being said, the iPad Air is a bit of an exception to the rule as it retains the same rear camera sensor as the 4th generation iPad. We’re still talking about a 5MP sensor with f/2.4 lens, although the iPad Air now has a wider field of view with a 3.3mm focal length (identical to the original iPad mini).
| Rear Facing Camera Comparison | |||||||
| Sensor | Resolution | Aperture | Focal Length | ||||
| Apple iPad Air | 5MP | 2592 x 1936 | f/2.4 | 3.3mm | |||
| Apple iPad 4 | 5MP | 2592 x 1936 | f/2.4 | 4.3mm | |||
| Apple iPad 3 | 5MP | 2592 x 1936 | f/2.4 | 4.3mm | |||
| Apple iPad 2,4 | 0.7MP | 960 x 720 | f/2.4 | 2.0mm | |||
| Apple iPad mini | 5MP | 2592 x 1936 | f/2.4 | 3.3mm | |||
The rear facing camera tends to shoot at lower ISOs than the rear camera on the iPad 4. Since there’s no substantial change in the sensor or lens system however, the result is less noise but a darker image in low light situations. I suspect this might be more of a configuration default for the software layer driving the H6 ISP in Apple’s A7. Image quality is surprisingly good:
Even lower light shots come out fairly well:
Although obviously noise goes up appreciably once you get into really dark scenes:
I took a bunch of photos at the NC State Fair as well as on my trip out to Santa Clara following the iPad launch event in the gallery below.
Despite using the same ISP as the iPhone 5s, there’s no 10 fps burst capture mode on the iPad Air. Similarly there’s no slo-mo video recording mode either. The iPad Air does inherit the other benefits of the new H6 ISP however. Image capture is still insanely quick, which makes me wonder if the A7’s ISP also leverages that large on-die system cache.
| Front Facing Camera Comparison | |||||||
| Sensor | Resolution | Aperture | Focal Length | ||||
| Apple iPad Air | 1.2MP | 1280 x 960 | f/2.4 | 2.15mm | |||
| Apple iPad 4 | 1.2MP | 1280 x 960 | f/2.4 | 2.18mm | |||
| Apple iPad 3 | 0.3MP | 640 x 480 | f/2.4 | 1.8mm | |||
| Apple iPad 2,4 | 0.3MP | 640 x 480 | f/2.4 | 1.8mm | |||
| Apple iPad mini | 1.2MP | 1280 x 960 | f/2.4 | 2.2mm | |||
The front facing camera does see an improvement in sensitivity thanks to a larger sensor format. My understanding is this is the same sensor/lens combination as what’s in the iPhone 5s and 5c. Similarly to its implementation in the 5s, Apple seems to use the new front facing camera system to drive to lower ISOs and/or higher shutter speeds. You typically end up with a lower noise/sharper image, although sometimes there is a brightness/exposure tradeoff.
The other feature leveraged by the new front facing camera is the inclusion of a second microphone for noise cancellation. The goal here is to use the second mic to cancel out background noise and improve the quality of the audio you’re actually trying to record (presumably your voice during FaceTime for example). The impact is pretty noticeable. I ran an iPad 4 and an iPad Air side by side while playing a background track and have embedded the resulting videos below:
In the iPad Air sample video my voice comes across considerably clearer, as you’d expect given the Air’s second mic.
Video
Video capture settings look unchanged from the iPad 4. We’re still dealing with ~17Mbps High Profile videos from the rear camera and ~10Mbps Baseline Profile H.264 from the front camera.
Video quality out of both is pretty good for a tablet. In well lit scenes rear camera quality is definitely sufficient for sharing on the web.

Actually, the new Kindle 8.9 has at least as good a display as the iPad Air, if not better:"Amazon’s always touted the displays on its tablets, and the screen it’s using on the HDX 8.9 is a doozy. At a ridiculous 2560 x 1600-pixel resolution and 339ppi, it’s either higher-resolution or more pixel-dense than virtually any other tablet on the market. It also has great viewing angles, excellent color reproduction, and high brightness levels. It’s really just a great screen, whether you’re gaming, watching video, or reading text — it’s right up there with, if not better than, the Retina display on the iPad Air."
- The Verge
"While the speakers feel like something of an afterthought, Amazon is clearly waging a battle on the display front. The company keeps upping its game, and indeed, the screen here dazzles, with 2,560 x 1,600 resolution and a pixel density of 339 pixels per inch. That's a big jump up from the HD 8.9's 1,920 x 1,200 display, not to mention the new HDX 7-inch tablet, which has a 1,920 x 1,200 screen. It's even enough to make the iPad Air's 2,048 x 1,536 resolution (264 ppi) seem modest. It's simply a gorgeous thing to behold, making movie watching a downright pleasure. Heck, it even managed to make Sharknado look pretty good, which is no small feat. All in all, images are sharp, the level of detail is impressive and the colors are vibrant."

But, I do agree with you that too many let their personal opinions colour their reading of reviews. I prefer Android and PC, but I have an iPad and have tried several Macs. Even though I prefer other units, there is no point in denying the excellent quality and style Apple products come with. They, like Nintendo, only release products "when they are done" - no rushing.

Really? You clearly never looked over one of their Android phone reviews. They are stupidly detailed.dsumanik - Wednesday, October 30, 2013 - link
Read this review with a grain of salt. Anand lai shimpi is heavenly vested in apple stock, doing everything he can to boost the dismal situation.Thinner bezels and light weight do not hide the fact that functionally, this iPad is the same as the previous 2 generations.
Sent from my ipad3, which will be upgraded when apple actually updates the product line.
Here's some basic ideas mr cook:
Wireless charging
Fingerprint scanner
Thunderbolt sync or usb3
Haptic feedback
NFC

Wireless charging - deeply inefficient charging; maybe 50% of energy is actually picked up by the deviceFingerprint scanner - probably getting one next gen
Thunderbolt sync or USB3 - maybe; and it is possible the hardware already can do this; but Thunderbolt (a PCI-E spec) will never happen
Haptic feedback - dead concept; no one actually wants this; RIM failed at haptic
NFS - in a tablet? and is NFC actually used? No, it isn't.

Agree with your wireless charging argument, but that limits you from charging your iDevice if you don't have your own cable. All android phones use microusb, so it's not hard to find one at all (speaking of the real world here). Apple chose not to afford themselves that luxury.Fingerprint scanner : Although I think it's a gimmick and useless for the masses (almost everyone except from corporate users), they could have done it now, since they already have it in 5s. Why wait till next gen?
Haptic feedback : You probably would have said the same about touchscreens around 2005. I tried staying away from smartphones altogether until the Xperia Pro because there were no decent phone with a proper keyboard. After that I finally gave in an bought the HTC One and I still really miss my physical buttons. Haptic feedback could cure that.
NFC : I use it as much as I use Bluetooth (which is to say not a whole lot but a very handy feature still and I'd like to have it)

Yeah. Anyone who wanted to be truly objective would stopping running all of those tests that the iPad Air does so well in. If you want to be truly balanced, you have to run a bunch of tests that the iPad sucks at too, like maybe an .apk loading test or a malware running test.zeagus - Wednesday, October 30, 2013 - link

Anand himself has stated where his loyalties lie: He said during a podcast that his advertisers were the motivating force behind the change in the look of the website. Obviously he is a slave to his advertisers who obviously want as much crApple content on the site as possible; of course they want it be overwhelmingly positive. This crApple model generates tons of hits for theverge and it does the same for anandtech.markthema3 - Monday, November 4, 2013 - link
He changed the layout of the site to better place the advertisments on the page. That's not catering to an individual company. The conclusion that he is therefore a slave to the advertisers is unfounded.
