We’ve suspected this all along, but the latest leaks from sources close to Apple strongly suggest that the forthcoming iPhone 6s will feature a much improved rear camera.
A person “within Apple’s supply chain” told Business Insider Malaysia that a new five-element lens is being produced, designed to work with a 12 megapixel sensor upgraded from the 8 megapixel sensor found in current iPhone 6 handsets. The unnamed person went on to reveal that a more complex six-element lens has also been ordered for a future undisclosed iPhone.
Each element in a lens enables further refinement of the image, including the correction of unwanted distortions which can result in the bending of straight lines, as well as the removal of any coloured fringes which can often appear at the edges of an uncorrected photo.
A six-element lens isn’t necessarily better than a five-element one. The number of elements required to achieve adequate correction will depend on the angle of view of the lens and the physical size of the imaging sensor. If the physical size of the sensor remains constant, then when the number of megapixels is increased, the lens will have to perform better to deliver a sharp enough image to the smaller pixels. This may require additional elements to correct smaller imperfections which may not have been picked up by a lower-resolution sensor. Many competing phones, such as the Samsung Galaxy S6 and the OnePlus 2 already come with six-element designs.
