Opteka 500mm f/8

Opteka 500mm f/8 is a camera glass with a long focal length, which is suitable for capturing distant subjects. It has a manual focus system, which means the photographer needs to adjust the focus manually. The lens has multiple glass elements and coatings to ensure high-quality image resolution. The aperture of the lens is f/8, which is a moderate aperture for telephoto lenses. The build quality of the lens is good, and it is designed to be durable. The lens produces a pleasing bokeh effect, which is the quality of the out-of-focus areas in an image. The lens does not have autofocus, which means the photographer needs to focus the lens manually. The manufacturing time of the lens is not mentioned. There are alternative lenses with similar specifications available in the market.

Positives:
