Cosinon 55mm f/1.2 Auto (Tomioka)

Cosinon 55mm f/1.2 Auto (Tomioka) is a camera glass that produces a beautiful bokeh effect, which means that the out-of-focus areas of an image are smooth and pleasing to the eye. It has a manual focus system, which means that you need to adjust the focus ring to get a sharp image. The lens has 7 elements in 6 groups, which helps to produce sharp and clear images. It also has a lens coating that helps to reduce flare and ghosting, which can be a problem when shooting in bright light.

This photo lens was manufactured in the 1970s, and it is still popular among photographers who want to achieve a vintage look in their images. It has a wide maximum aperture of f/1.2, which allows you to shoot in low light conditions and create a shallow depth of field. The build quality of the lens is solid, and it feels sturdy in your hand.

In terms of resolution, this photographic lens produces sharp images when stopped down to f/2.8 or f/4. However, at f/1.2, the edges of the image can be a bit soft, which can be a creative effect or a drawback depending on the situation.

Overall, the Cosinon 55mm f/1.2 Auto (Tomioka) lens is a great option for photographers who want to experiment with a vintage lens and create a unique look in their images.
