What is E-TTL II autoflash?
E-TTL mode, also known as E-TTL autoflash, is the mode where the camera uses information obtained through the lens (“TTL”) to calculate how much light the flash needs to emit for the appropriate brightness. The camera then automatically sets the flash output accordingly. This is known as a flash metering system.
What is TTL on a flash?
TTL stands for “Through The Lens” and is a metering system that controls the power of the flash based on exposure settings as determined by the camera.

What is Sony TTL?
TTL-flash mode measures the light from the subject that is reflected through the lens. TTL metering also has a P-TTL metering function, which adds a pre-flash to TTL metering, and an ADI metering function, which adds distance data to the P-TTL metering.
What’s the difference between Ettl and TTL flash?
The ETTL system uses a preflash before a photo is taken to improve the quality of the exposure. This allows for the same evaluative metering sensors to be used that are used for ambient light. TTL and A-TTL flash modes use a dedicated flash metering sensor. With tricky ambient light, these modes can produce subpar results compared to ETTL.
What does E-TTL stand for on a camera?
E-TTL mode, also known as E-TTL autoflash, is the mode where the camera uses information obtained through the lens (“TTL”) to calculate how much light the flash needs to emit for the appropriate brightness. The camera then automatically sets the flash output accordingly.
How does the E-TTL II flash metering work?
E-TTL II uses information about the distance from the lens to the subject in its evaluation of the optimal flash output. E-TTL II identifies the subject by using the AF point.
Is the Canon E-TTL II flash system still functional?
E-TTL II remains functional with *all* Canon EF lenses, but when using direct flash, E-TTL II is at its best when distance data is available.
