SmallRig has announced the release of a pair of external optical viewfinders designed to provide photographers with alternative framing options for their cameras. Best known for manufacturing robust camera cages, rigging solutions, and mounting hardware for video and photo production, the company is now stepping into the realm of classic analog-style accessories with its new 28mm and 35mm External Optical Viewfinders.
The newly introduced 28mm External Optical Viewfinder provides a 28mm full-frame equivalent field of view through a carefully engineered optical glass system. To assist photographers with composition, the accessory features built-in 3:2 frame lines etched or projected into the glass. These lines help users accurately compose shots captured with a true 28mm equivalent lens, whether it is a fixed prime lens permanently built into a compact camera or an interchangeable prime lens mounted to a mirrorless body.
Because these units are strictly optical devices rather than electronic viewfinders, they do not rely on digital data transmission, proprietary hot shoe communication protocols, or internal batteries. This analog nature means the compatibility list extends far beyond any single manufacturer. While SmallRig explicitly lists a broad selection of compatible camera models from major brands including Fujifilm, Sony, Nikon, Canon, Ricoh, and Leica, the viewfinders should theoretically function on any camera equipped with a standard universal cold or hot shoe design, provided the parallax offset is managed by the user at close shooting distances.
For contemporary digital photographers, the Ricoh GR series stands out as the most obvious and immediate beneficiary of the 28mm viewfinder. Extremely popular among street photographers, the Ricoh GR III and GR IV premium compact camera lineups—including their specialized HDF variants—rely on a fixed, high-quality 28mm equivalent lens. To maintain their famously pocketable, lightweight form factors, Ricoh deliberately omitted built-in electronic viewfinders from these cameras, forcing users to compose exclusively via the rear LCD screen. While many street shooters embrace the screen-only workflow for its discretion and speed, a dedicated segment of the photography community still prefers the traditional eye-level framing experience. SmallRig’s new release introduces a much more affordable path to achieving that setup.
Ricoh has historically offered its own branded external optical viewfinders for the GR series, such as the GV-1 with dual 21mm and 28mm frame lines, and the more compact GV-2. However, these proprietary accessories are notoriously expensive for what they are, with the Ricoh GV-2 retailing around $246.95 brand new. By comparison, SmallRig’s market entry undercuts official manufacturer options by a wide margin, lowering the financial barrier for photographers who want physical framing frames without breaking the bank.
Alongside the wide-angle model, SmallRig has also launched a 35mm External Optical Viewfinder, though its practical application within modern digital photography is somewhat more specialized. While mainstream digital compact cameras with built-in 35mm-equivalent lenses generally feature built-in electronic viewfinders or rangefinder-style finders, the market for interchangeable lens cameras lacking native EVFs does exist. For instance, certain entry-level mirrorless bodies or minimalist bodies omit built-in viewfinders to save space and cost. If photographers choose to pair such a camera with a 28mm or 35mm prime lens, SmallRig’s external viewfinders offer an alternative method for framing scenes at eye level.
Beyond digital systems, these accessories may find a niche audience among users of vintage analog film cameras. Older mechanical rangefinders and compact film cameras often suffer from degraded optics, fogged glass, misaligned rangefinder patches, or missing viewfinders altogether. For analog shooters dealing with damaged or nonexistent factory finders, a clean, modern third-party optical viewfinder can serve as an affordable restoration alternative, breathing new life into classic film bodies.
SmallRig’s marketing materials also highlight an appeal to digital photographers who simply desire a more traditional, analog-style shooting experience, even when using modern mirrorless bodies equipped with high-resolution electronic viewfinders. Whether a substantial market exists for adding a purely optical, non-magnified frame to a camera that already possesses an EVF remains to be seen. Given that nearly all the contemporary digital camera lines cited by SmallRig as compatible already feature built-in electronic viewfinders, the 35mm version in particular borders on a specialized niche. Nevertheless, the company is betting that a segment of the enthusiast community values the tactile, battery-free aesthetic of optical glass framing.
Ultimately, the primary selling point driving interest in SmallRig’s new accessories is their accessibility. Priced at under $50 each, these units offer a budget-friendly entry point from an established and trusted brand within the broader photographic equipment ecosystem. The SmallRig 28mm and 35mm External Optical Viewfinders are both available now for purchase, retailing for $46.99 each.
