Used Tiffen 72mm Lens Hood B11802
Hood does not lock when collapsed. It simply springs back.
Please note that it can be used on 28mm lenses, but it vignette on 24mm lenses.
But it is not damaged in any way, no cracks or dents. This lens hood is fully operational and functions as intended. I would rate it an 8, on a scale from 1 to 10.
Lens Hoof has a depth of 32mm
