Photax 500mm f/8.0

It has a long focal length of 500mm, which allows for distant subjects to be captured in detail. The lens has a fixed aperture of f/8.0, which means that the amount of light entering the lens is limited, but it can still produce sharp images if used correctly. The lens has a number of lens elements, which are coated to reduce glare and improve image quality. The build quality of the lens is sturdy and durable, which makes it suitable for outdoor use. The lens has a good resolution, which means that it can capture fine details in an image. The bokeh, or the quality of the out-of-focus areas in an image, is decent but not exceptional. The lens is a manual focus lens, which means that the focus needs to be adjusted manually using the focus ring on the lens. There are alternatives to this lens, such as autofocus lenses, which can be easier to use for some photographers. The manufacturing time for this lens is not specified. Overall, the Photax 500mm f/8.0 lens is a good option for photographers who need a long focal length lens for capturing distant subjects, but are comfortable with manual focus and limited aperture.
