The main advantages pointed to by Apple to describe your smartphone iPhone 4S - this camera. Except for the new dual-core processor A5 other significant hardware differences model in comparison with the previous version of the iPhone 4 does not. Relative to the camera used epithets such as "unprecedented for a camera phone" and "possibly the best camera on the phone." However, despite the fact that the devices have not yet gone on sale, but because they have to be evaluated only on the information provided by Apple, have already appeared in doubting that the 8-megapixel module used in the iPhone 4S is better than other solutions used in phones Smartphones and other manufacturers. Of course, we are not talking about primitive compared to the number of effective pixels, which obviously loses iPhone 4S as the market is a device with a 12-megapixel matrix. The main critic addressed Specialist at Nokia Dinning Damien (Damien Dinning), which examined in detail the specifications of the camera and the iPhone 4S its competitors. It is worth noting that despite the express Dinning objective comparison, it can not be completely disinterested party. The principal limitation of the quality of the images for a camera installed in the mobile phone is the relatively small size of the matrix used. This is dictated by how modest size device, and the need to place a camera in it except a lot of other elements. Additionally, a small thickness of the device can not use optics with large distances between the lenses. The solution is to use these lenses mounted in a digital "Soap", but these smartphones on the market - there are only regular phones like the series Pixon from Samsung. Because accurate information about the structure of the lens iPhone 4S yet, it is not possible to really appreciate it. But here's a comparison matrix used is possible. megapiksey race now practically disappeared, as had a limit beyond which increasing the number of pixels at the expense of reducing them, it was ineffective because the noise begins to rise. This has prompted manufacturers to limit the matrices having 8.12 MP. In the iPhone 4S has an inverse matrix backlighting, which is said to compensate for deficiencies of light, while the aperture is chosen f/2.4, which also compensates for the decrease in the size of pixels. However, these measures do not allow Apple to get a matrix that would at the amount of 1/3.2-dyuyma have 8-megapixel resolution and assimilated more light than any other used in smartphones. For this indicator, Apple was able to bypass the Android-smartphone Sony Ericsson Xperia Arc and Samsung Galaxy S II, which also have a BSI matrix. But compared with conventional, but the larger matrices installed in Symbian smart phones Nokia has failed. Apparatus year ago Nokia N8 has a matrix which is 77% bigger, and gets 124% more light than the iPhone 4S matrix even with the BSI -compensation. Moreover, the matrix used in the Nokia N86 and aperture size of f/2.4 1/2.3-dyuyma also has a greater ability to gather light, which is defined as 3.28 against 2.88 at the iPhone. In addition it has been suggested that the optics from Carl Zeiss, installed in the Nokia smartphones will be superior to that used Apple. But the fact that the iPhone 4S exceeds all phones on the market by the speed of obtaining the frame, Damien Dinning is not disputed.
