The Sony A7III is a versatile mirrorless camera that offers both an electronic viewfinder (EVF) and an LCD screen, giving photographers multiple ways to compose and capture images. Knowing how to turn on and properly use the viewfinder is essential for maximizing control, improving focus accuracy, and achieving precise framing. Whether you are shooting in bright daylight, low-light conditions, or fast-paced environments, understanding the viewfinder options on the Sony A7III can significantly enhance your photography experience. This topic provides a comprehensive guide on activating and using the viewfinder effectively.
Understanding the Viewfinder on the Sony A7III
The Sony A7III features a high-resolution 2.36-million-dot electronic viewfinder that displays the scene in real-time. Unlike optical viewfinders on DSLR cameras, the EVF shows exactly what the sensor captures, including exposure, white balance, and depth-of-field effects. This makes it a powerful tool for precise shooting. The EVF also includes useful overlays such as focus peaking, grid lines, and histogram data, allowing photographers to adjust settings without taking their eyes off the scene.
Benefits of Using the Viewfinder
- Improved StabilityHolding the camera to your eye reduces hand shake and helps stabilize shots.
- Accurate ExposureThe EVF shows real-time exposure, helping to avoid under- or overexposed images.
- Enhanced FocusFeatures like focus peaking highlight the areas that are in sharp focus.
- Reduced GlareShooting through the viewfinder is ideal in bright sunlight where the LCD screen may be hard to see.
- Professional CompositionGrid lines and other overlays assist in aligning horizons and subjects.
How to Turn On the Viewfinder
Activating the viewfinder on the Sony A7III is straightforward, but understanding the available options ensures that you can use it efficiently. Here are step-by-step instructions
Method 1 Using the Viewfinder Selector
- Locate the viewfinder/LCD switch on the back of the camera, usually near the EVF.
- Flip the switch to the EVF position to activate the electronic viewfinder.
- Once switched, the camera automatically turns off the rear LCD screen and displays the scene in the EVF.
- Adjust the diopter control next to the viewfinder to match your eyesight for a clear and sharp display.
Method 2 Using the Menu Settings
The Sony A7III also allows you to control the viewfinder through the camera menu. This method is useful if the EVF does not automatically activate or if you want to customize the display settings.

Customizing Viewfinder Settings
Once the EVF is activated, you can adjust various settings to optimize your shooting experience. Customization allows you to tailor the viewfinder to your specific photography needs.
Diopter Adjustment
The diopter adjustment dial, located next to the viewfinder, allows you to focus the EVF display to match your eyesight. Turn the dial until the scene appears sharp and clear, which is particularly useful for photographers who wear glasses.
Brightness and Color Settings
- In the menu, navigate to Display/Auto Display and adjust EVF brightness according to ambient lighting.
- Set color modes if desired to make certain details or focus peaking more visible.
Focus Peaking and Grid Lines
- Enable focus peaking to highlight sharp areas in the scene, helping with manual focus accuracy.
- Use grid lines to assist with composition, ensuring straight horizons and balanced framing.
