The transparent viewfinder is the defining feature. Measuring 60.8 x 47.8 mm, it maintains more than 50% light transmission, allowing users to see the subject through the device while a simple head-up display overlays shooting mode, battery status and exposure information.

Four aspect ratios are available: 16:9, 4:3, 3:2 and 1:1. Corresponding crop lines appear within the viewfinder, providing basic composition guidance without requiring a conventional digital preview screen. Instead of holding the camera directly against the face like a traditional optical viewfinder, users frame scenes through it almost like looking through a small window.

The C100 also has a practical feature that could make it particularly interesting to film photographers: built-in light metering. Its center-weighted system measures brightness across the central 25% of the frame and displays ISO, aperture and shutter-speed information in the viewfinder. Users can match the ISO to their film and use the suggested exposure information as a guide.

The camera captures both still images and video, with storage provided by TF/microSD cards supporting capacities of up to 128 GB. A USB-C 2.0 connection allows the camera to connect directly to a phone for previewing and transferring files. Battery life is rated at more than 1.5 hours of continuous shooting.

Godox does not list the camera's resolution in its own specification sheet. Digital Camera World reported a basic output of 1,920 x 1,080, or around 2 MP, along with 1080p video recording. That puts the C100 firmly in the category of a casual memory-making device and learning tool rather than a serious imaging system.

Its appeal therefore lies less in technical performance than in the experience it creates. By removing instant image review while retaining a digital light meter and basic framing information, the C100 offers a deliberately slower and more tactile approach to photography in an increasingly screen-heavy camera market.
