Feel the super-wide-angle lens G charm: Sony FE 12-24mm F4 G
The Sony FE 12-24mm F4 G is a zoom super wide-angle lens inside a light bulb. Indeed, the 12MM end of the FE 12-24mm F4G is so broad that it is not easy to grasp the corners. The result of this is that there are too many unnecessary items around to break into the shooting screen. In addition, since the 12MM end is close to a viewing angle of about 121 degrees, the problem of deformation caused by such a perspective effect (non-fingerprint distortion) is often unacceptable. Fortunately, through the “upright guideline guide†method in Photoshop ACR9.3 or Lightroom 2015.3 and above, you can correct the perspective of the Z-axis into a straight line, making it from the 3-point perspective into a public acceptable The 2-point perspective deformation. Take Tadao Ando's “Church of Light†as an example. One is a three-point perspective. One is a two-point perspective after correcting the Z-axis, and the same is a perspective of about 121 degrees from the 12-mm end. Which one is more acceptable? There is no doubt that the two powers do harm. I believe most people will choose 2 perspective distortion effects. Architectural photographers generally use this method to correct distortions caused by perspective. Here to intersperse to talk about Photoshop ACR9.12.1 or Lightroom 2015.12, upgrade to this version, FE 12-24mm F4 G lens correction there, but FE 12-24mm F4 G 12 is not necessarily correct so much The dark corner correction, I think it depends on the situation, and sometimes the vignetting can make the focus more focused on the center of the screen. This is a typical, 12MM side-by-side photo that I have corrected and is almost a 1-point perspective. The following are the photos that I corrected to 2-point perspective. This 2-point perspective indoor view looks more comfortable. However, the above approach is not absolute, and sometimes we will use the 3-point perspective of this kind of exaggerated distortion to achieve the special picture effect we need. Therefore, we must be good at using the characteristics of the focal length of the lens to achieve the screen effect we need. Speaking of this, is this ultra wide angle FE 12-24mm F4 G suitable for shooting people? From the perspective of my use, I do not think it is not suitable, but depends on how you come to view the composition. These are all shot on the 12th side. When people occupy the scenery more than they want to fit, they can also have the effect of stretching the legs. The FE 12-24mm F4G is a very good, ultra-wide-angle lens that does not bear the G mark. Although most of my photos use the 12MM end, it does not mean that it cannot be shot with its other focal lengths. In addition, the sharpness of this head is not bad, fully met the expectations of the official MTF chart. With Sony A7R2 to shoot, you can even find a lot of details that are usually ignored even when shooting, but in the 12MM end of the surrounding vignetting appears slightly larger.

Is this Corki more cute? 
This Hongqiao volley SOHO is not even more magnificent?

So if you're an indoor or architectural photographer and use Sony's E-mount full-frame camera, you shouldn't miss it. Also if your subject matter is a starry sky or you want an over wide angle landscape with more than 16 MM effect, then you can't miss it. Because it is necessary to use a wide-angle lens in a wide-angle area, wide-angle openness and visual perspective impact can be exhibited.
