Camera lens adapter KiwiFotos Nikon 1 to Pentax K mount SB3938

The KiwiFotos Nikon 1 to Pentax K mount adapter SB3938 allows photographers to attach Pentax K-mount lenses to Nikon 1 series mirrorless camera bodies. This mechanical adapter provides a secure physical connection between the lens and camera, enabling use of legacy Pentax K optics on compact Nikon 1 cameras. It supports manual focus and manual aperture control when the attached lens exposes those controls, providing a practical way to expand lens options without electronic communication between lens and body.

Advantages

This adapter offers a robust metal construction that ensures stable mounting and repeatable alignment between lens and camera. By preserving the original flange focal distance mechanically, it maintains the ability to achieve infinity focus with compatible Pentax K lenses on Nikon 1 bodies. The adapter is lightweight and compact, keeping the camera setup portable while adding compatibility with a wide range of manual lenses.

Suitable for

• Photographers who own Pentax K-mount lenses and want to use them on Nikon 1 mirrorless cameras
• Users seeking to experiment with manual-focus lenses and vintage glass
• Content creators who require specialised optics or unique rendering from legacy lenses
• Technicians or hobbyists testing lens performance across different mounts

Key specifications

• Mount type: Pentax K (lens) to Nikon 1 (camera)
• Connection: Mechanical only, no electronic contacts
• Focus control: Manual focus supported
• Aperture control: Manual aperture control supported when present on lens
• Material: Metal alloy construction for durability
• Finish: Matte or anodised surface to reduce reflections
• Weight: Lightweight design suitable for mirrorless setups

How to use

Attach the adapter to the Nikon 1 camera body by aligning the adapter’s camera-side mark with the camera mount index and rotating until it locks in place. Then mount the Pentax K lens to the adapter by aligning the lens index and turning until secure. Set the camera to a compatible shooting mode that allows manual exposure control. Focus and adjust aperture directly on the lens; the camera will not communicate electronically with the lens so metering and EXIF data for lens specifics may be limited depending on camera capabilities.

Usage recommendations

Use the adapter primarily with manual-focus lenses and verify infinity focus on a test subject after mounting. When shooting handheld, consider using a steady support due to lack of autofocus. Check lens aperture mechanism for smooth operation before extended shoots and avoid forcing mechanical rings to prevent wear on older lenses.
