In addition, this machine is also a model equipped with a shaft tilt display that can only adjust the angle as a commercially available camera equipped with a full size sensor. Since I was able to borrow the actual machine from Sony this time, I decided to see the skill while shooting the main body to every corner and taking a night view.

Photo review

The one we used for this review was "Α99The body (left) and the optional lens "Vario-Sonnar T * 24 - 70 mm F 2.8 ZA SSM SAL 2470 Z".

"Α99The logo looks something like this.

A lens mount whose outer periphery has become orange is a feature on the design. Also, in this interior, a CMOS sensor with 35 mm full size (35.8 x 23.9 mm) and effective pixel count of approximately 24.3 million pixels is built in.

With "Translucent Mirror Technology" adopting a transmission mirror inside, unlike conventional single lens reflex cameras, the mirror does not move up and down even during shooting, so by simultaneously delivering light to the image sensor and the AF sensor, high speed focus It is possible to make it possible.

Approximately 1772 grams with lens.

Please be aware that it may take 7 to 8 seconds for the shutter to turn off after turning on the power once the battery is removed. As it is in a hurry, it is recommended to turn on the power supply early in scenes where it is necessary to release the shutter.

I took a picture.

Pictures and movies taken by actually bringing "α99" to Osaka at night are as follows. Unless otherwise noted, the settings are taken automatically by the handheld shooting. Please note that the shooting data is compressed when uploading to the server or YouTube, so the picture quality is deteriorated compared with the original data.

Taking a picture of the night view of the building is like this. Another one below is an enlarged view of the red frame.

When enlarging the inside of the red frame of the above picture, noise is suppressed quite steadily for nighttime shooting.

When you set to manual mode and open the aperture to F 2.8, it is possible to take a picture with a blurred background.

Conversely, if you narrow down to F22, it will be a picture that was deeply focused.

When creating an articleThe lowest price at the price .com is only 228,000 yen unitSo, for most people it is not a cheap price to buy, but when you consider that you can shoot both pictures and images using a full size sensor it's not necessarily too expensive. In addition, it is attractive that it does not have in the full-sized machine of other companies in that it has a triaxial tilt liquid crystal monitor. That's why it is recommended for people who want to shoot pictures and images with image quality but do not want to have more than one piece of equipment, or those who frequently use high / low angle photography.
