The benefits of using a smartphone camera are not always sufficient as they are not as advanced as we would like, and sometimes a longer optical zoom lens is needed because it provides greater shooting flexibility during different situations. At other times it does not hurt that the camera incorporates an optical image stabilizer to correct the slight movements of the hands. Thus, it is not surprising that external cameras have been invented as cell phone accessories. They are attached by adapters and mounting brackets to the smartphone and some can function with tablets. Outwardly they appear as a zoom lens, but in reality they are a complete camera with similar features to the best compact cameras in the market. They can take pictures, videos and include the tasks and controls of SLR cameras. For example, they allow you to adjust other parameters such as white balance.
They are called lens type cameras such as the Sony QX family. The Japanese manufacturer launched its first models in 2013: DSC-QX10 and DSC-QX100. The simplest is the Sony DSC-QX10, which costs 250 dollars, and the retail price of the Sony DSC-QX100 is above 498 dollars. Both are suitable for Android mobile devices or to accompany an iPhone or an iPad. It has become known that the Japanese company is preparing a new QX camera with better features than the current ones, noted for its 30x optical zoom. This will allow us to maintain image quality throughout the zoom range without it degrading. These 30 increases help to capture images of distant subjects in great detail, and are also useful for portraits.
That rumor about the new QX lens type camera with an optical zoom range of 30x has just been published on Sonyalpharumors. This would be a clear improvement over the models currently on sale. Keep in mind that the Sony DSC-QX100 features a Zeiss Vario-Sonnar TF1.8 lens with a 3.6x optical zoom in conjunction with an Exmor R CMOS sensor of 1 inch capable of capturing 20.2 megapixels. Meanwhile, the Sony DSC-QX10 has a Sony G lens with an optical zoom of 10xy with an Exmor R CMOS sensor with 18.1 megapixels. Both integrate a powerful BIONZ image processor and an optical image stabilizer system with SteadyShot brand.
Both can record videos in MP4 format with a resolution of 1,440 by 1,080 pixels at 30 fps (frames per second). Images are stored on memory cards, which can be Memory Stick Micro, microSD, microSDHC and microSDXC. They also have a USB 2.0 port with micro connector, a wireless communication capability via Wi-Fi and to this must be added the NFC (Near Field Communications) technology for quick connection to compatible devices. Still, these lens type cameras do not provide too much extra weight to your smartphone. The Sony DSC-QX10 weighs 105 grams (with battery and Memory Stick Micro card included), and the Sony DSC-QX100 is 179 grams.
