Do you still remember the lyrics of the shutter you once pressed?Do you still remember the shutter you pressed?
Which painting? Who took it?
Is the scene unforgettable?
The corners of my mouth slightly curved
Is it your sincere smile?
What a beautiful expression
Why can't I see it
Do you still remember the journey you've taken?
On the beach? Wearing a dress?
Encounter what kind of waves
The dawn of Yangming Mountain or the sunset of Gulangyu Island
Who will make you fall for him
The wandering poet outside the window
Singing his songs of spring and summer
I have so much luggage, but I'm missing one concern
No matter how beautiful the scenery is
It's just an empty shell
Let me forget him in a blink of an eye
Let me forget him in a blink of an eye

The difference between mechanical shutter and electronic shutterA mechanical shutter was a device that relied on mechanical structures (such as springs, gears, and other components to drive the shutter curtain to open and close) to control the time when light entered. It first appeared in the era of film cameras. The electronic shutter relied on electronic signals to control exposure, which was achieved by directly turning on and off the image sensor.
The difference between the two was as follows:
1. ** In terms of shooting experience **: The mechanical shutter will make a machine collision sound when shooting, while the electronic shutter will not make a sound when shooting (the click sound is simulated). Therefore, the mechanical shutter is not suitable for shooting scenes that need to be silent, such as conference speeches, wild animals, wedding ceremonies, theater performances, etc., while the electronic shutter is suitable for such scenes.
2. ** Jelly effect **: Mechanical shutters can effectively avoid the "jelly effect"(the image may be distorted when the electronic shutter shoots fast-moving objects), but the electronic shutter may cause the jelly effect when shooting high-speed objects. However, the global electronic shutter of some cameras may not have this problem.
3. ** Service life **: Mechanical shutters are mechanical devices and have a maximum number of uses (usually hundreds of thousands of times). Electronic shutters do not have mechanical moving parts, so there is no such problem.
4. ** Shutter speed **: Electronic shutters can have a higher shutter speed (some cameras can reach an electronic shutter speed of 1/32000 seconds), suitable for shooting fast-moving objects such as sports competitions or high-speed racing. Although mechanical shutter speeds can also meet the shooting of some moving objects (for example, a certain camera shutter speed can reach 1/16000 seconds), it is generally inferior to electronic shutters in terms of high-speed shutter speed.
5. ** In terms of vibration **: Since the electronic shutter does not have the movement of the shutter curtain, there is no shutter vibration. During long exposure or when using a super telephoto lens, it can reduce the blurriness caused by vibration. The mechanical shutter has shutter vibration.
6. ** Picture stripes **: Under the same parameters, some electronic shutter cameras may have stripes in artificial light scenes (for example, the electronic shutter image of the SonyFX30 under the LED light has zebra stripes). Mechanical shutters have fewer such problems.
