• The 17° Optical Viewfinder features bright framelines for 28mm, 35mm, and 50mm lenses, ensuring precise framing for your photography needs.
• This standalone Optical Viewfinder operates purely on optical principles and lacks a metering function, meaning it does not display metering results or communicate with digital or film cameras.
• In dark scenes or scenes with large differences in brightness, the bright frame lines may not be clearly visible on the 17° viewfinder. This is normal. You will need to shift your eye up, down, left, and right to confirm the frame lines.
• The 17° viewfinder displays all frame lines; it is not possible to display any one frame line individually.
• Equipped with a cold shoe mount, the 17° Optical Viewfinder can be easily attached directly to your camera's hot or cold shoe for convenient use during filming.
