a7iii appeared in great cost-performance. You can use both photos and videos, a7iii is enough power as a Mirrorless interchangeable lens camera.
This post is an impression of a replacement from the first a7 and the second generation a7ii etc.

First of all

It is a great camera.
A good function of the a7 series is well taken in, and a function which it is not necessary is being deferred.

Photos and videos common subject matter

– ISO with ISO 100-51200 with the top of the series
– The functions of the Auto Foucus system are the same as the top of the series
– The viewfinder and LCD monitor are the same as the first a7! That is, coarse resolution. It seems that we cut price by dividing here. I am affirmative.
– a9 is better for the imaging device.

About Photo

– The photo size is 6000 x 4000. Well enough. The top is 7952 x 5304, such as a7Riii.

About Videos

– 4K shooting is possible.
– Focus follow. If you do not suddenly change the focus position, it will be chasing quite a bit. Even if it goes off, it fits quite quickly with the shutter button

Sense of holding

– It got a little heavier
– The operation buttons and around handles, feel clogged.
– The contents of MENU is also impressive with items filled up. Although it can be finely set, it is probably hard to understand for the first person of SONY a.
– I think that the battery has gotten between double from triple better.

I think that it was not easier than the first generation and the second generation.

Buttons

– It has a touch panel.
– There are almost no menus that can not be registered in the button (at least until the second generation I feel that there was quite a lot of things that can not be put )

The number of buttons has increased, and the freedom of each item that can be set is increased considerably.
So the first thing I thought was that you can switch the APS-C size with just one button.

Convenient APS-C size

In fact, sesquialteral zoom can be switched with buttons.

For example, in Leica Elmar 90mm L39 of the old lens, the shortest shooting distance is 100cm, so I can only get to this side.

So, assigned APS-C button.
You can make it to about 1.5 magnification.
Compared to desorption of macromount, it is quite handy. I think that the image quality does not change almost.

Side

About memory card

Is it the first time that two slots?
However, I have never experienced that 64GB SD has been full, at the work of photograph.
Even in video work, I often change it on the way. I think that two-SD use is scary and I will not do it.
It is my personal opinion.

Perhaps, everyone a common opinion about Memory Stick.

Output terminal etc.

Is not there a better way?
At least, I’m worried about the cover.

etc.

Silent shutter is nice

It really does not sound at all, almost zero.

Although I used rental a 7 S ii at work, It is because a 7 iii was not in time for the release date.
Anyway, the silent shutter is very good.

It was an event shooting job.
Compared to when there was a shutter sound, Everyone does not conscious of the camera at all.

If everyone does not conscious, their expression will be natural.
Especially smiley face and seriously face, I think that it is easier than shutter sound appear for a good expression.
There was a notice beforehand that there was a camera shooting, but I think that this effect was great.

I was pleased to know that the silent shutter is also in a7iii.
