Digital enthusiasts who are concerned about Apple's new products watched the live broadcast of Apple's conference last night. The students who are not concerned about it should have seen the overwhelming news today. I believe many students have a question. Why does iPhone 7 Plus have two lenses?
Last night, Apple released the iPhone 7 and iPhone 7 Plus. In addition to the two sizes, the biggest difference in appearance is the difference in the back.
First of all, say iPhone 7.
After studying the camera parameters of the iPhone 7, it is a satisfactory upgrade. It can be said that the iPhone 6 Plus is an upgraded version of the lens.
Compared to the iPhone 6s Plus, the lens aperture of the iPhone 7 has increased from Æ’/2.2 to Æ’/1.8, and this change in aperture has little impact on the depth of field. The greatest value lies in the same exposure time as the lighting environment, with the same increase in sensitivity. Into the amount of light. Translating adult words means that you can get better shooting results under low light conditions.
Second, Optical Image Stabilizer is no longer exclusive to the Plus Series! (At this moment, there should be applause.) Like me like the iPhone 6s rather than Plus students, the biggest reason is basically because Plus head is too big, one-handed inconvenience. But for me who love to take pictures, the most difficult choice is actually optical image stabilization. The significance of optical image stabilization is to stabilize the image through optical compensation during shooting, which reduces the generation of jitter. The practical effect is that it is not easy to shoot out at slow shutter speeds.
Larger apertures and increased optical image stabilization have also significantly improved the quality of video capture. In low-light conditions, iPhone 7 can shoot more stable and clear video.
There are other upgrades, such as face and body recognition, True Tone flash from two to four, support for wide color gamut, and more. As for the lens changes from 5 to 6 pieces, there will be no intuitive feeling from the use. If the coating is not good, it may be more likely to produce flares.
Let's talk about the iPhone 7 Plus.
The dual lens of the iPhone 7 Plus is really equipped with two different lenses and sensors. Unlike previous dual-lens phones, the focal lengths of the two lenses are different. One is a wide-angle lens and the other is a medium-focus lens. Of course, Apple calls it telephoto, but according to the equivalent focal length of about 56mm, it belongs to the range of medium coke.
The wide-angle lens is equivalent to the iPhone 28 with an equivalent 28mm focal length and Æ’/1.8 aperture. The medium focal length lens is equivalent to a focal length of about 56mm and a Æ’/2.8 aperture. An equivalent 28mm focal length lens has a field of view of about 75 degrees, and an equivalent 56mm focal length lens has a field of view of about 45 degrees. That is, standing in the same position, the photograph taken with the medium focal length lens has a narrower field of vision. . Intuitively, the medium-focus lens zooms in on the subject.
This is equivalent to installing two lenses with different focal lengths on a mobile phone, and the focal length can be selected according to the theme. For example, when taking food, portraits, and close-ups, using a 56mm medium-focus lens will give you a totally different feeling than before.
I believe that many students are interested in the depth of field effect brought by dual cameras. Thanks to the new A10 Fusion chip, an optimized image processor is built in. When you take a photo, it will take hundreds of billions of calculations to make the photo less noise, the picture more pure, and also brings faster focus Speed ​​and more accurate white balance, of course, also include more complex "depth of field" algorithms.
To be honest, I am not optimistic about the effect of the current technology. Of course, I believe that Apple will definitely bring better results than other dual-lens phones, but the current official proofs are only very effective.
This does not deny the contribution made by Apple. It is of course a good thing for users that mobile phone manufacturers are aware that they can use algorithm to make another camera game function. However, at the current level, there is still room for improvement. However, the Depth of Field effect function on the official website is still Coming Soon, and it is expected to be effective after the official launch.
For self-paced students, the iPhone's front-facing FaceTime HD camera has also been upgraded, from 5 million pixels to 7 million pixels, and video recording has been increased from 720P to 1080P. Of course, it offers the same wide color gamut support as the rear lens.
Let's take a look at the samples released by Apple's official website. I chose several more representative ones. It can be seen that Apple is very confident in the low light shooting of the iPhone 7. In the sample posted on the official website, the photo of low light accounts for a very large proportion, and the effect looks good. .
In addition to camera changes, the biggest change is audio. The speakers of the iPhone 7 and iPhone 7 Plus have become stereo, and they will work better when put out. The 3.5mm headphone jack is removed and the included Lightning jack headphones and 3.5mm jack converter are included in the package. In other words, using wired headsets and charging is not possible at the same time. If you want to use at the same time, you can only consider wireless headphones. .
There is also a very important point, this time the iPhone has a certain waterproof capacity. The official description is "The iPhone 7's body shell has been redesigned to be the first iPhone with splash-proof features. Now, whether it's an overturned glass, splashed water, or flying dust, you're all Get better protection than ever before."
The official website says that the iPhone 7 and iPhone 7 Plus waterproof standards can reach IP67 level. IP67 is defined as "protecting dust from inhalation; protecting against temporary soaking." This does not encourage you to take the iPhone to play in water, but rather to reduce your worries while using the iPhone. For example, you can take a bath with your mobile phone, and you can rest assured that you can take pictures in light rain, and you don't need to worry about the phone being soaked when you touch the cup.
iPhone 7 and iPhone 7 Plus also have different degrees of improvement in other aspects, such as each generation of new products will emphasize the faster running speed, better battery life, more brilliant screen and so on.
So, what cell phone do you use? Will you consider buying an iPhone 7 or an iPhone 7 Plus?
