The Olympus A2-0925 AH-25FR Visual Obturator is an essential accessory for photographers using the Olympus OM-1, OM-2, or OM-2n film cameras. This visual obturator is designed to provide a clear viewfinder image during flash photography, enabling accurate focusing and composition.
The AH-25FR obturator features a black chrome finish, which not only adds to the aesthetic appeal of your film camera but also ensures durability and protection against dust and other elements. It is made of high-quality materials, ensuring long-lasting performance and reliability.
The obturator has a built-in neutral density filter with a density of 0.3, which helps to reduce the amount of light entering the viewfinder during daylight flash photography. This filter improves the visibility of the image in the viewfinder, making it easier to compose and focus the shot.
The AH-25FR obturator also has a quick-release mechanism, which allows for easy installation and removal from the camera. It is designed to fit securely and snugly into place, ensuring that it does not obstruct the lens or viewfinder when not in use.
One of the standout features of this visual obturator is its synchronization with the camera's flash. When the flash is fired, the obturator opens to reveal a clear view of the scene for a brief period, allowing the photographer to check the composition and focus of the shot before the film is exposed. This feature is especially useful when shooting fast-moving subjects or in low-light conditions.
In summary, the Olympus A2-0925 AH-25FR Visual Obturator is an indispensable accessory for Olympus OM-1, OM-2, and OM-2n film camera users who require accurate and consistent flash photography. Its high-quality construction, built-in neutral density filter, quick-release mechanism, and synchronization with the camera's flash make it a must-have tool for any serious photographer.

3. Build quality: Some users have reported issues with lens mount or build quality, which may lead to focusing issues or the need for frequent adjustments.
