Frequently Asked Questions

Is the TTL Flash the Same as the P-TTL Flash?

The TTL Flash and the P-TTL Flash have the same functionality. The only difference is the acronyms as it represents the different camera brands.

The TTL or “through the lens” is lens metering. It measures the light in a scene; it controls the amount of light coming through the camera’s lens, which can be used for a well-balanced exposure. 

What Makes Flash Lighting Different Than Continuous Lighting? 

Flash lighting is intermittent light. When you activate the shutter, the flash fires fast, and it lights up your subject. After it is done, it turns itself off. 

Meanwhile, continuous lights are lights that can extend for a long period of time. It stays continuously, and it is always on; once you are done, you are the one who needs to turn it off. 

Conclusion

The Sony A7RIII is packed with advanced functionalities and features. Attaching a flash can expand your horizon as it lets you practice different styles to enhance your photography skills. 

The best flash for Sony A7RIII can give you all the advantages to thrive in the photography industry.
