Simmod Wider Base Rear Lens Cap (ARRI LPL)

Rear lens protection requires both coverage and stability.

This cap introduces a wider support geometry for handling and storage.

The Simmod Wide Base Rear Lens Cap (LPL Mount) is a protective cap designed for LPL-mount lenses, combining rear element protection with a widened base structure to improve stability during use.

Function

• Protects the rear element and mount interface of LPL lenses
• Reduces exposure to dust and debris when the lens is not mounted
• Designed for storage, transport, and maintenance workflows (B&H Photo Video)

Wide Base Geometry

The cap features an extended base design:

• Approximately 2.5-inch base diameter
• Allows the lens to be placed upright on flat surfaces without tipping (B&H Photo Video)
• Centers the lens weight over a broader footprint

This improves stability during:

• Lens prep and handling
• Maintenance and servicing
• Temporary placement between setups

Deep Cap Design

• Increased internal depth to accommodate shimmed lenses (B&H Photo Video)
• Provides clearance for lenses with adjusted flange configurations

Fitment System

• Includes a removable rubber gasket for friction-based retention
• Gasket helps reduce ingress of dust and debris
• Includes shim(s) to adjust fitment across LPL mount tolerances (B&H Photo Video)

Fit can be tuned depending on lens mount variation.

Construction

• Manufactured from molded plastic
• Black finish
• Lightweight construction

Material selection balances durability with ease of handling.

Mechanical Characteristics

• Standard LPL mount engagement
• Friction-assisted retention via gasket
• Stable base for vertical lens positioning

System Behavior
