Testing a 1977 Helios 44-2 f/2 M42 copy. There's a small oil leak on inner rear element and it causes unwanted bokeh effects, but it's hidden when apeture is closed a stop or two. Sharp lens when correctly focused.
Footage is not color corrected or sharpened.
Camera: Canon 550D
Music: “Le petit jardin (with Les Gauchers Orchestra)” (by Lee Maddeford)
