Sony's "α7 IV" is a versatile mirrorless camera with an excellent autofocus function.

Sony's latest full -size mirrorless camera "α7 IV" is one of the best products of the commercially available "beginners" mirrorless cameras.Certainly, there are cameras with more resolution sensors in the world, and the α7 IV lacks some video functions on high -end models.However, it is an all -round camera that can take both photos and videos, and it is hard to find any more products.The module -type action camera "DJI Action 2" is super lightweight at 56g, but the α7 IV, which has a regret, has an image sensor of 3 million pixels, so it can be said that the capacity is almost "infinite".Common sense buffer memory is newly combined.Thanks to the RAW format or JPG format compressed data, you can keep shooting until the battery level is lost.In addition, the performance of autofocus (AF) has been greatly improved, and the function of focusing on the subject's eyes has been improved.It also has various video shooting modes including the HYBRID LOG GAMMA (HLG) method that can play videos on HDR -compatible TVs.

The body of the α7 IV is not much different from the previous model.However, the grip became quite large, giving a more solid impression than before.This new grip is very similar to those used in the “α7S III” model for video creators.I felt it was a bit harder to hold than my personal "α7R II", but the way it feels depends on the size of my hand.If possible, you should actually check it at a nearby store.Despite the bigger body, it is in a small category of full -size mirrorless cameras introduced so far.The operation button on the back is almost the same as the latest model of other α7 series.The dial also has a multi -controller that moves in four directions, which can also be a joystick that moves the AF focusing points, and six customizable buttons.It is enough to achieve your favorite operation, and if you set it from the menu screen only once, that will be enough.This is a good thing.Because Sony's user interface is still in a maze, there is no chance to use the menu.On the other hand, the new functions that you want to focus on in the α7 IV are in the contents.Since it is equipped with a 3 million pixel back -illuminated CMOS sensor, the resolution is improved and high -quality photography can be expected even in places with low light.The performance of this new image sensor is not only "α7 III" with a sensor of 2,42 million pixels, but also exceeds the "EOS R6" of Canon, "Z 6II" of Nikon, and Panasonic's "LUMIX S1".ing.Nevertheless, the α7 IV is an introductory machine among Sony mirrorless cameras.In terms of resolution, the "α7R IV" with a 61 -megapixel sensor is outstanding.It should be noted that the image sensor of the α7 IV is likely to be installed on the successor to the lightweight type "α7C" of the α7 series.The successor to the α7C is expected to be released in 2022, so if you want a small camera, you should wait.The image sensor is new, but the processor is the same as the one that is installed in the "α7S III" suitable for video shooting, which provides a wide range of dynamic range.The α7 IV is a wide range of dynamic range with a maximum of 15 stops, like the α7S III, so it greatly expands the range of post -processing and other processing.Also, thanks to the new processor, the processing speed is higher than the previous model α7 III (up to 8 times according to Sony).I couldn't compare the two aircraft because the α7 III was at hand, but I never felt that the α7 IV was slow.
