HOA A1 Is a Screen-Free Camera Designed to Prove Photos Are Authentic

A new South Korean startup called Lutra Inc. has introduced a camera brand built around a rather unusual idea: capturing authentic photographs in an era when images can increasingly be generated or manipulated. Its first camera, the Humans of Authenticity (HOA) A1, takes that concept literally by removing the traditional viewfinder and rear LCD screen.

Instead, the camera uses a rectangular frame on its body to help users compose photographs. The design is somewhat reminiscent of the Godox C100, although the HOA A1 has a different approach to image verification and viewing.

“HOA stands for ‘Humans of Authenticity.’ We seek authenticity in an era where anything can be generated. We also want to be a trusted friend where people like that come together,” the company says.

A Camera Without a Screen or Viewfinder

The HOA A1 replaces a conventional viewfinder with a physical rectangular frame. Users look through the frame with both eyes open to compose their photographs.

“Frame is designed to be a viewfinder. Look through it with both eyes open, and feel the air. You can capture the scene just as you see,” HOA explains.

Inside, the camera uses a 16-megapixel Sony IMX sensor measuring 1/2.53 inches, paired with a lens offering a 35mm-equivalent focal length and F1.75 maximum aperture. Images have a resolution of 4,656 × 3,104 pixels.

The camera also features autofocus and can focus as close as 0.1 meters.

Without a rear display, users cannot immediately review their photographs on the camera itself. Instead, HOA says users will be able to view captured images by tapping a smartphone against the back of the camera. Instructions for using this feature are expected to be published later.

ShootProof Aims to Verify Photo Authenticity

The HOA A1’s most distinctive feature is ShootProof, a photo verification technology designed to let anyone confirm that an image has not been altered since capture.

The system uses a secure chip to sign a digital fingerprint of each photograph and record it in a public registry. HOA currently uses blockchain technology for this registry, although the company says other public registries could also work if they meet the anonymity requirements outlined in its white paper.

ShootProof is designed to let photographers verify the authenticity of their images without automatically revealing their identities. Photographers can remain anonymous by default and prove authorship only when they choose to.

The system shares some goals with C2PA, an open standard for recording the provenance and history of digital content. HOA’s approach places particular emphasis on photographer anonymity and the ability to verify images across compatible devices.

Photographers can capture images without an internet connection. However, an online connection is required to authenticate photographs securely.

Color and Image Quality Still Being Refined

For now, HOA has not released sample photographs captured with the A1. The company says it is still fine-tuning the camera’s color and tonal characteristics in collaboration with photographers.

This means there is still little information available about the camera’s actual image quality and how its 16-megapixel sensor and F1.75 lens perform in real-world shooting conditions.

The company’s emphasis so far has been on the camera’s shooting experience and its photo authentication system rather than conventional image-quality specifications.

Pricing and Availability

The HOA A1 is priced at ₩360,000 KRW, or approximately $289. The camera is not yet available for purchase or preorder, but interested customers can reserve a unit ahead of its December 21 launch.

The first release, called the HOA A1 First Edition, will be limited to just 100 units. Each camera will feature an individually engraved number from 001 to 100. Customers can reserve their preferred number on a first-come, first-served basis before launch.
