Focus Screen Lens Rear Cap For L-Mount

A fully printable focusing screen lens cap, L-Mount version, meticulously adjusted for the rear lens hood of L-mount lenses, ensuring perfect alignment between the focusing screen and the lens. Due to the wider angle of light incidence compared to Leica M-mount lenses, I have significantly reduced the thickness of the rear lens cap, potentially compromising protection against sharp objects.

Known Issues:
1. Sigma L-mount lenses retract to their minimum aperture when removed, resulting in low light conditions and suboptimal performance. Panasonic and Leica lenses haven't been tested; aperture behavior is unknown.

2. All lenses with electronic focusing rings will not achieve sharp focus when using this lens cap due to the inability to rotate the focus ring.
