Wow, what is that, four issues now? iMaps, WiFi, scuffs, and purple lens flares in the camera when facing bright lights?

Gizmodo sensationalized the title though. Apple basically just said don't point it directly at bright lights.

Apple Acknowledges iPhone 5 Camera Problem, Says You’re Holding It Wrong

After initially denying it, Apple has acknowledged the iPhone 5's purple flare camera problem in an email to a Gizmodo reader. Their solution: "Angle the camera away from the bright light source when taking pictures."

Here's their complete answer:

Dear Matt,

Our engineering team just gave me this information and we recommend that you angle the camera away from the bright light source when taking pictures. The purple flare in the image provided is considered normal behavior for iPhone 5's camera. If you wish to reach me regarding this case number *********, please contact me at 1-877-***-**** ext. *******. I currently work Thursday-Monday: 7:00am - 3:30pm Mountain Time.

There are typical first batch issues. The iPhone 3G couldn't make calls because it couldn't switch between Edge and 3G properly. Antenna-gate. Yellow screens. iOS bugs. And yet they sell 20-30 million of these phones every quarter, because a few minor early adopter issues aren't enough to ward off people from buying the best phone on the market.

Mine works perfectly, by the way. No issues so far.

Well if that is the best apple can do, you can keep it. I will use a great Samsung phone that actually does what it says it will do plus many things apple can only dream of.

I'm sure they are disappointed they will not have your business.

How are lens flare not normal? Lens flares have been around with every camera. Some slr lenses get them at night even with a decent light source.

Purple lens flares that distort the image. The following image shows the lens flare and the iPhone 5's is not normal.

Yep. Every camera ever made with a lens will get a lens flare. If the light enters the first element at a certain range of oblique angles, you'll get a lens flare.

What might be the issue here though is the placement of the camera on the body of the phone causing more flares than previous models or some change with the **** piece of plastic/glass that get puts into any cell phone camera.

One of my pet peeves is people talking about their cell phone camera when I'm shooting withmmy real camera. First question they always ask "is that a pro camera" followed by "how many megapixels does it have"? Usually a good opportunity to educate someone on camera basics.

Oh hell no that's not normal. That's not a lens flare, that's a POS sensor getting overloaded.

Or perhaps that sapphire glass they put on there might be scratch resistant but with crappy optical characteristics. When I first read about it I thought it was a case of purple fringing which happens to some very good lenses as well. But that is certainly not normal purple fringing but something totally different.

It could be contributing. The sun in the i5 shot is slightly closer to a huge gradient change in dynamic range, but that much chromatic aberration is unbelievable and is most likely a combination of the two. You even have a fringe on the bottom left of the image which shows that light is bouncing around all over the place. However, the major blow out of the sun itself looks like a poorly designed sensor.

It kind of looks like some of the channels are getting blown out and overloading the neighboring channels as well. By channels I'm not talking about traditional RGB channels, but what I've heard called data channels. They were a major bottleneck years ago with sensor development for speed shooting. Canon and Nikon were both pouring money into it to get higher speed shooting with an acceptable noise to signal ratio.

Regardless, it seems like an issue of both contributing. It may be correctable with software, but it looks like a junky third party POS phone camera. Not what you want to see for the flagship of your telecom device especially considering how much cameras are used on the modern incarnation of a smartphone.

IIRC, Canon has yellow/green aberration, Nikon has purple/red/blue depending on if its the gold line or other lenses, Sigma gets yellow/blue, and Canon L-series can get red too.

Bottom line every lens can get CA, but the stuff shown in the i5 comparing to the i4 is unacceptable. Its affecting the entire image from top right to bottom left.
