Features

In-Body Image Stabilization Function

The 5-axis IBIS provides effective shake correction for both stills and video, allowing for sharper images and smoother footage without the need for a tripod. It compensates for five types of camera shake, ensuring stable handheld shooting in various conditions, making it a valuable asset for photographers and videographers alike.

Eye Detection Autofocus Function

The Eye Detection AF automatically detects and focuses on the subject's eyes, ensuring sharp focus in portraits and other scenarios where precise focus is crucial. It can be used with AF-C mode for fast and effective eye detection/tracking performance when shooting stills, transforming portraiture by maintaining optimum focus on moving subjects.

Tilting LCD Screen Function

While the camera features a 3-inch LCD screen, it does not have a tilting function. This limits the ability to easily compose shots from high and low angles, requiring users to rely on the viewfinder or adjust their shooting position to achieve the desired composition. This can be a drawback for those who frequently shoot from unconventional angles.

External Microphone Input Function

The camera includes a microphone terminal (3.5 mm Stereo minijack), allowing for connecting an external microphone for improved audio quality. This is beneficial for video recording, enabling clearer and more professional-sounding audio compared to the built-in microphone. It's particularly useful for vlogging, interviews, and other video projects where audio quality is important.

USB Power Supply Function

The camera supports internal battery charging via Multi/Micro USB Terminal or USB Type-C Terminal, allowing it to be powered via USB. This enables extended shooting sessions without worrying about battery life, as the camera can be continuously powered using a power bank or wall adapter. It's particularly useful for time-lapse photography and other long-duration shooting scenarios.

Focus Peaking Function

The camera features focus peaking, which highlights areas in focus on the LCD screen or viewfinder, assisting with manual focusing. This is helpful when using manual focus lenses or in challenging focusing situations, making it easier to achieve sharp focus. It's a valuable tool for photographers who prefer manual focus or need to fine-tune focus in specific scenarios.
