Many people may be wondering how the iPhone 6 and 6 Plus cameras are holding up. I have to say that I am impressed with the new generation of iPhone cameras, especially the Plus version.
The iPhone 6 Plus camera has two significant improvements: improved focus and optical image stabilization (the regular 6 only has digital image stabilization). The focus improvements are extremely noticeable, especially in dark environments. You are likely to see much less 'jumpy' focusing as you may find on the iPhone 5 or 5s.
The image stabilization provides a nice improvement in sharpness in low light, but Apple used it in a very smart way to also reduce the noise in the photo (slower shutter speed and capping the max ISO lower). This produced much better images in very dim environments.
The following list shows what improvements came to the iPhone 6 Plus, that will not be available to iPhone 5s users who simply update to iOS 8
- Optical image stabilization (iPhone 6 Plus only) or digital image stabilization (iPhone 6 and iPhone 6 Plus) - Phase detection auto-focus (PDAF) - Facetime front-facing camera can gather 81% more light, and features an f/2.2 aperture (f/2.4 in previous iPhone models) - Better processor for noise reduction - 1080p video at 60 frames per second (compared to 30 on previous iPhone), and 240fps with a lower resolution shot at 720p (120fps on iPhone 5s)
You may be thinking, the iPhone camera only has 8 megapixels, how is that acceptable when something like the Nokia Lumia has 40 megapixels.
Because megapixel count isn't the sole relevant determiner for the quality of a digital camera's photos, much like processor clock speeds can't really tell you how "fast" a processor is.
Megapixel counts, at this point, are a marketing item, and not really a measurement of the performance of a given sensor under some given lighting condition, or how you're likely to use the camera in your phone. Does the Nokia Lumia let you do some amazing things with the 40 megapixel shots it gets? Sure. But they're not high quality shots because the sensor is capturing 40 million pixels.
A high megapixel shot, in low light, that's grainy and unusable because the sensor in your camera can't handle low light conditions, is still going to be an unusable shot, regardless of the pixel count.
