This is my contribution to Cee’s Black and White Photo Challenge: Lines and Angles.
Continuing my testing of various lenses adapted to a mirrorless camera I went for a walk with a 25mm f/1.4 CCTV lens attached to the camera last Thursday and spotted this tree bark with all sorts of lines and angles.
The lens only just covers the camera sensor at maximum aperture. Stopping the lens down causes it to vignette badly so I kept it at maximum aperture for the walk. Because the lens only just covers the sensor the edges of the photo are swirled and blurred with some vignetting in the corners.
Some different tree bark photographed on a walk last winter using a normal camera lens.
