Among all the other things Apple has figured out is the camera on the iPhone. I recently switched from an iPhone 5 to the Galaxy Note 3. While it has numerous advantages over the iPhone (for my use), its 13MP camera still lags well behind the iPhone 5 and 5s. It’s not all about the hardware either. Apple does a great job with the image processing and I just get better images out of it than I do any other smartphone I’ve used.
Apple has been stuck on the 8MP camera for three generations now, dating back to the iPhone 4S from 2011. However, the aperture has dropped from f/2.4 in the iPhone 4S/5 to f/2.2 in the iPhone 5S. Apple has clearly demonstrated that 8MP is enough for a smartphone as it has continued to focus on the overall photography experience.
Rumors of much larger models coming in for the iPhone 6 release (up to 5.5″ displays as the rumors go) are accompanied by rumors that Apple will again step up the camera hardware, including the resolution, to a 10+MP sensor and a f/1.8 lens. Additionally, rumors suggest that the iPhone 6 will see a new resin lens filter, which is lighter and thinner than comparable IR filters and should result in better image quality fro the 10+MP CMOS sensor.
