Canon sx740hs4k settings

Creative position statement: I take pictures of Xiao Bai, and I can only take pictures in automatic mode. Cameras are used for work. This article wants to share my experience from a non-professional perspective.

Reasons for purchase

Last year, for work reasons, I needed to buy a digital camera with simple operation and clear photos, which was mainly used to take some photos at work. As a photographer, I don't know anything about frame, composition and color, so I don't pay much attention to the performance of the camera. The only requirement is that the camera is better than the mobile phone. I picked it on the Internet and finally decided on this "Canon SX740 HS" with 40x optical zoom.

Let's take a look at the main parameters of this camera:

About 20.3 effective pixels 1/2.3-inch CMOS sensor +DIGIC 8 image processor,

ISO 100-3200，

Supports up to 3840×2 160 and 30p video shooting.

4.3- 172mm F3.3-6.9 fixed zoom lens, equivalent to full-frame 24-960mm.

1 1 group 13 lens optical structure,

The anti-shake effect of reducing the shutter speed by 3.5 gears at most,

3-inch LCD screen, about 920 thousand pixels, 180 degree folding,

Shutter speed 15- 1/3200 seconds,

Up to about 10 frame/sec, high-speed continuous shooting (fixed focus), 7.4 frames/sec (continuous focus),

The camera size is110.1× 63.8× 39.9 mm, and its weight is about 275g (fuselage only).

To be honest, there are few parameters above that I can understand.

Ha ha laugh

Relieve the burden of.

For the convenience of later use, I also equipped a tripod and dual batteries.

Use your senses.

There are different views on image quality. I don't know much about it anyway. I just think that the photos taken by P30 have higher brightness, while the photos taken by the camera have higher color reproduction and are closer to the colors actually seen by the eyes.

What I want to introduce to you most is its mobile phone interconnection function, as well as 40x optical zoom and160x hybrid zoom.

If you want to connect your mobile phone, you need to download the "Camera Connection" APP on your mobile phone and choose wifi or Bluetooth connection. After connecting the camera's wifi signal, your mobile phone can not only view photo information, download or delete photos, but also control the camera.

I think this function is great. You can download beautiful photos to your mobile phone anytime and anywhere, and then upload them to major social platforms.

Now the telephoto lens has been broken by mobile phone manufacturers. First, Huawei shot the moon at 50 times zoom, and later Xiaomi shot 1 100 million pixels. However, due to the limitation of the thickness of the mobile phone, only 3 or 5 times optical zoom can be realized at most, and the rest can only use digital zoom. PS: The principle of optical zoom is to change the image size by changing the focal length, while the principle of digital zoom is to enlarge a fixed photo, so digital zoom will affect the image quality, but optical zoom will not. This camera can achieve 40 times optical zoom, plus digital zoom, which can reach 160 times.

The linear distance from the shooting point is about 600 meters.

Video shooting

SX740 supports 4K video recording. With the rise of short videos in recent two years, this has undoubtedly become another sub-item. In the official publicity materials, double anti-shake can be realized by gyroscope and CMOS image sensor.

In order to test the video anti-shake performance of the camera, I recorded a video while walking with my camera and mobile phone without using the pan-tilt stabilizer.
