Filter Adapter and Lens Cap set, JJC SB5435 – 52mm filter mount for Sony RX100 II/III/IV/V

JJC SB5435 is a 52mm filter adapter and matching lens cap made for Sony RX100 series compact cameras (models II, III, IV, V). The adapter screws onto the camera’s collapsible lens and provides a standard 52mm female thread for attaching screw-in filters such as UV, neutral density (ND), or circular polarizers (CPL). The set includes a center lens cap that fits the adapter to protect the lens surface and mounted filter from dust and light mechanical impact when the camera is stored or transported.

Advantages

The adapter converts the proprietary collapsible lens mount into a common 52mm filter thread, enabling use of a wide range of aftermarket screw-in filters and step-up accessories. The included center cap offers simple mechanical protection without adding significant bulk, and the lightweight construction maintains the compact form factor of the RX100 series. Installation and removal are quick, allowing photographers to switch between filtered and unfiltered setups in the field.

Suitable for

• Landscape photography with graduated or ND filters
• Travel and street photography where lens protection is needed
• Outdoor shooting that requires UV or CPL filtration to control reflections and haze
• Video work using neutral density filters for exposure control

Key specifications

• Filter thread size: 52mm female
• Compatibility: Sony RX100 II, III, IV, V collapsible lens series
• Material: lightweight metal or alloy construction for stable mounting
• Includes: threaded adapter ring and matching center lens cap
• Finish: matte or anodized surface to reduce reflections
• Weight: minimal added weight to preserve camera portability

How to use

Align the adapter with the front of the collapsed lens and gently screw it on until it seats securely; avoid excessive force to prevent cross-threading. Once mounted, screw a compatible 52mm filter into the adapter until snug. To protect the lens and any attached filter, press the included center cap onto the adapter when the camera is not in use. To remove, unscrew the filter first, then the adapter, storing both in protective pouches to avoid scratches.

Usage recommendations

Use filters with slim or low-profile rings to minimize vignetting on wide-angle settings, and check compatibility with stacked filters before extended shoots. Clean threads regularly and avoid overtightening to maintain smooth installation and removal.
