Last Sunday's Mobile World Congress announcements seem like forever ago at this point. I feel like we've been living with the Samsung Galaxy S7 and the LG G5 for months after hearing as much about them as I have.
Then there's the HP Elite x3. If you're a fan of Windows phones, this was the highlight of Mobile World Congress. The device was praised as what the Lumia 950 should have been and what fans are dreaming that the Surface Phone could be.
After all, the device is powered by a Snapdragon 820 chipset, 4 GB of RAM, has an 8 MP front camera, a 16 MP rear camera, 64 GB of internal storage, Windows Hello by means of fingerprint and iris scanner, and a 5.96" QHD AMOLED. What's not to love?
The answer is the rear camera.
I know what you're thinking. "It's 16 MP! How can it not be awesome?" I'm about to tell you. Not only is this camera not going to be as good as our beloved Lumias, but we're talking mid-range quality here.
It all started when I was looking at a picture of the device, admiring its beauty. Then I looked at the camera and I noticed something odd, particularly for a flagship phone.
The flash is a single LED. To put it in perspective, the Lumia 950 and 950 XL have a triple LED flash. Just about every mainstream flagship has at least a dual LED and there's a reason for that.
A dual LED flash, or a two tone flash, provides more accurate color. When Panos Panay announced the triple LED flash on the Lumia 950, he noted that "it means you don't look like a ghost".
The only devices that you'll see with a single LED flash is in the low to the mid tier.
But wait, there's more...
Then I went a bit deeper into the camera specs. Of course, it's important to note at this point that anything lacking here is subject to change, as there's still not a lot that's known about the Elite x3.
The rear camera has an f/2 aperture, something that was a flagship feature a year ago; however, with f/1.9 in the Galaxy S6, f/1.8 in the LG G4, and f/1.7 in the Galaxy S7, it's not such a flagship feature anymore, especially since the latest Moto G has the f/2 rear sensor that originally shipped with the Nexus 6.
We can forget about that for a moment. We don't actually know the sensor size. We've seen from numerous Lumias with large sensors and smaller apertures than f/2 can be perfectly OK. In fact, most Lumias with Pureview cameras had apertures that were smaller than f/2, but they had larger sensors.
All of the above would be fine if the device used optical image stabilization (OIS), phase detect autofocus (PDAF), or laser focus. Spoiler: the Elite x3 has none of the above.
OIS is what keeps the camera from shaking when you do. In fact, every Windows phone that says Pureview on it has OIS. To take it one step further, all a camera needs to be qualified as Pureview is OIS.
NOTE: Pureview was originally oversampling a 41 MP image into a smaller image (Nokia Pureview 808). When the Lumia 920 came around, it was still Pureview without oversampling because it had OIS. In short, Pureview is defined as oversampling, OIS, or both.
PDAF and laser focus achieve the same means through different technologies. Apple started using PDAF with the iPhone 6 and Samsung uses it as well. LG took the road of laser focus. The Lumia 950 and 950 XL have also adopted PDAF.
These two features allow the camera to focus incredibly quickly, allowing the user to take a perfect photo in a minimal amount of time.
Resolution isn't everything
Most companies like to market their camera by talking about the resolution. The only reason for this is because it allows them to put a number on how good the camera is. The higher the number, the better the camera, right?
Wrong. With camera resolutions as high as they are, resolution means very little. A higher resolution photo does, however, allow the user to crop the photo without losing as much quality as you would with a lower resolution photo.
A 4K UHD display is about 8.3 MP. This is at a 16:9 aspect ratio. At a 4:3 aspect ratio, we're down to about 6.2 MP. Anything larger than that needs to be scaled down. Note that at 16:9, a 1440p display is about 3.7 MP and 1080p is about 2.1 MP.
Note that the above paragraph is putting it in simple terms, since this isn't an article about camera resolutions and why they do or don't matter. This is technology, where there are always other factors involved.
In other words, a 10 MP sensor with a 1/2.5" sensor size, f/1.9 aperture, PDAF, OIS, and a dual LED flash is going to produce a much better image than a 16 MP sensor with no PDAF, no OIS, and a single LED flash.
When HP announced the Elite x3, they made it very clear that it is a business device. It is not designed with consumers in mind. Heck, that camera is most likely designed to be awesome at scanning documents.
The device will likely never see the inside of a retail store, but we do know that consumers will have the option to buy it from sources such as HP.com. That's it, though. You have the option to buy a business class device. It's still a business class device.
Since the device isn't slated for release until this Summer and there are still a lot of details that we don't know about the Elite x3, anything could happen between now and then. Last I checked, Microsoft is still in the hardware business. With hardware like this, a Pureview camera, and better consumer availability, that might be the phone to actually wait for.
After all, this is Windows Mobile. This is where if you have nothing else, at least you have some of the best smart phone imaging on the planet. Personally, I can't imagine myself using a flagship Windows phone with a mid-range camera.
