Nikon-Pentax Adapter

Pixco Mount Adapter Ring for Nikon F Mount Lens to Pentax PK K Mount DSLR Camera K-3 III K-1 Mark II

Description:

This precision adapter ring allows you to mount Nikon F-mount lenses onto Pentax PK K-mount SLR camera bodies, creating a versatile bridge between two esteemed lens systems. It enables photographers to explore creative possibilities by utilizing a wider range of optics. Meticulously engineered to maintain correct optical registration, it guarantees reliable infinity focus and is constructed from durable metal for a secure connection.

Key Features:

1.Guaranteed Infinity Focus: Precision-manufactured to preserve the correct flange distance, enabling sharp and reliable focus from close-up all the way to infinity on the Pentax body, suitable for a full range of photography.

2.High-Precision Metal Build: Features precision-machined, chromed brass at critical connection points integrated into a robust metal body. This ensures a secure, tight, and wobble-free fit for stable imaging.

3.Pure Manual Control Experience: This is a purely mechanical adapter with no electronic pass-through. Focusing, aperture control (via the lens's aperture ring), and all exposure settings must be set manually. The camera must be in Manual (M) mode with "Using Aperture Ring" or "Shoot without lens" enabled.

4.Supports Special Optics: The design respects the optical registration distance, ensuring compatibility with lenses featuring CRC (Close-Range Correction) or floating element designs for maintained image quality.

Important Usage Notes:

1.Functionality Notice: This is a mechanical adapter only. It does NOT support autofocus, auto aperture, auto-exposure metering, electronic aperture coupling, Vibration Reduction (VR), or any electronic communication. All functions are manual.

2.Aperture Control: Aperture must be adjusted manually using the physical aperture ring on the lens. Lenses without an aperture ring (e.g., Nikon G-type, E-type) will have a fixed, unchangeable aperture when used with this adapter. Lenses with an aperture ring (e.g., AI, AI-S, D-type) are recommended.

3.Camera Settings: The camera MUST be set to Manual (M) mode. Enable the "Using Aperture Ring" or "Shoot without lens" option in the camera menu. Use stop-down metering with the camera's internal meter or an external light meter.

Compatibility:

Lens Side: Nikon F-mount lenses (for Nikon film and digital SLRs).

Note: Lenses with a physical aperture ring (e.g., AI, AI-S, D-type) are recommended. Lenses without an aperture ring (e.g., G-type, E-type) will have limited usability as the aperture cannot be controlled.

Camera Side: Pentax PK K-mount SLR cameras.
