Super Yashinon-R 300mm f/5.5

The Super Yashinon-R 300mm f/5.5 is a camera glass that provides a long focal length for capturing distant subjects. It has a manual focus system, meaning the user has to adjust the focus manually. The lens has multiple glass elements that help to produce sharp and clear images. The lens coating helps to reduce glare and improve contrast in the photos. It was manufactured in the past, so it may not be readily available in the market. The lens has a maximum aperture of f/5.5, which may not be ideal for low light conditions. The build quality of the lens is sturdy and durable, making it a reliable option for outdoor photography. The lens can produce high-resolution images, making it suitable for capturing fine details. Alternative lenses with similar focal lengths and apertures are available in the market, but they may not have the same optical quality as the Super Yashinon-R 300mm f/5.5.
