Simmod Wider Base Rear Lens Cap (ARRI PL)

Rear lens protection is typically treated as a basic requirement.

This cap introduces a structural approach to stability and fit.

The Simmod Wide Base Rear Lens Cap (PL Mount) is a protective cap designed for ARRI PL-mount lenses, combining rear element protection with a widened base geometry for improved handling and storage.

Function

• Protects the rear element and mount interface of PL lenses
• Prevents dust and debris from entering the lens mount
• Designed for use during storage, transport, and maintenance (B&H Photo Video)

Wide Base Design

The defining feature of this cap is its increased base diameter.

• Approximate 2.5-inch wide base
• Allows the lens to be placed upright on flat surfaces without tipping (B&H Photo Video)
• Distributes weight more centrally for improved balance

This design enables stable positioning during:

• Lens prep
• Maintenance
• Storage between setups

Deep Cap Geometry

• Extended depth accommodates lenses with rear shimming installed
• Ensures clearance for modified or calibrated mount configurations (B&H Photo Video)

Fitment System

• Includes a removable rubber gasket for friction-based retention
• Gasket helps reduce ingress of dust and debris
• Shim compatibility allows adjustment for mount tolerances (B&H Photo Video)

The fit can be fine-tuned depending on the specific PL mount variation.

Construction

• Manufactured from molded plastic
• Black finish
• Designed for lightweight durability

Material selection balances structural rigidity with ease of handling.

Mechanical Characteristics

• Standard PL mount interface engagement
• Friction-assisted retention via gasket
• Stable base contact surface for vertical positioning

System Behavior

• Fully passive mechanical component
• No electronic interface
• Does not affect lens optics or calibration

Notes

• Designed specifically for PL-mount lenses
• Compatible with shimmed lens configurations
• Does not provide environmental sealing
