SONY a7R III

Spread the love

Sony, which has pioneered the market for 35mm full-frame mirrorless cameras and has released another new companion “α7R III”.

As you can see from its name, the α7R III is the de facto successor to the high-pixel model “α7R II.” If it is a successor to the high-pixel model, I wondered if it would be a model change with a further increase in the number of pixels, but in fact the number of pixels is about 42.4 million effective pixels, which is unchanged from the α7R II.

What has changed is “almost everything except the number of pixels”. Focusing on the comparison between the previous model α7R II and the latest model α9 before the appearance of this machine.

Benefits of using “Sony a7R III”

The photo is beautiful

It is natural that the photo is beautiful because it has a high resolution mark “R”.

It’s natural, but after all it’s beautiful. 42.4 million pixels is not Date.

Can be cut anywhere

Since the a7RIII has high resolution and high pixels, it is easy to cut (trim).

This is a picture of fireworks, but even if you cut it to this size, it remains beautiful without any noise.

Good battery life

From “a7RIII” and “a7III”, the new battery is “NP-FZ100”.

In the past, the capacity of the “NP-FW50” was 1020mAh, but from the “NP-FZ100” it was 2280mAh, which is more than double the capacity, so the battery life has improved considerably.

Even if we go mountain climbing for a day and come back, 50% or more remains and it is considerably easier to use.

Recording media slot

The recording media slot is on the right side of the body. Like the α9, it has dual slots, the lower (SLOT 1) is for SD cards only (UHS-I, UHS-II compatible), and the upper (SLOT 2) is for SD cards (UHS-I compatible) and Memory Stick PRO Duo. It corresponds.

Relay recording (when one media is full, the recording destination is changed to the other media by automatic switching), simultaneous recording, distribution recording, copying between media, etc. are possible between the two recording media.

High sensitivity resistance

Check the high sensitivity resistance with ISO sensitivity. The higher the ISO sensitivity number, the brighter the picture can be taken even in dark places.

Comparing a7III and a7RIII, it looks like this.

100-51200 for a7III

100-32000 for a7RIII

You can see that a7III has higher ISO sensitivity and higher sensitivity resistance.

It depends on the lens, but the a7 III can shoot a wide range of images in both bright and dark places, so it is recommended for those who purchase a camera for the first time.

Summary

The α7R III, which is equipped with a high-pixel full-frame sensor and combines top-class AF performance and continuous shooting performance in a small body, is definitely a “great camera.”

However, although Sony’s technological ability to achieve numerous evolutions while suppressing the body size is commendable, there remains the problem that there is a limit to the miniaturization of the lens as long as the image sensor is full size. Isn’t it certain?

Even the Nikon D850, which can be regarded as a rival, may not have been sized just because it cannot be miniaturized. There must be an optimal solution for the balance between the camera and the lens.

Nonetheless, the characteristics unique to mirrorless cameras, such as the ability to perform fast hybrid AF and pupil AF even in viewfinder shooting, and the ease with which you can check the results of camera settings before shooting, are becoming more and more practical, and are indispensable functions. It is also certain that it is.

Since the α7R III is so complete, it makes me want to dream about the future of full-frame mirrorless cameras that will evolve regardless of size.
