Adaptador de objetivo para cámara Novoflex NEX/PENT – adaptador de bayoneta para Sony NEX a Pentax K, negro/azul

The Novoflex NEX/PENT adapter allows mounting Pentax K lenses on Sony NEX (E‑mount) mirrorless cameras while preserving precise mechanical connection and manual control of focus and aperture. Machined to tight tolerances, the adapter corrects flange focal distance differences so infinity focus is achievable with compatible lenses. It does not transfer electronic functions between camera and lens; exposure metering in most cameras is available as stop‑down or aperture‑priority metering when the lens is used without electronic coupling.

Advantages

High‑precision machining ensures accurate flange focal distance correction and reliable infinity focus. The adapter provides a secure, stable mechanical mount without electronic communication, maintaining full manual control of focus and aperture. The finish in black and blue offers visual distinction and durable protection for regular use.

Suitable for

• Photographers who want to use Pentax K lenses on Sony NEX (E‑mount) bodies
• Manual focus and manual aperture shooting, including vintage and legacy lenses
• Creative work requiring unique optical characteristics of Pentax K glass on mirrorless cameras

Key specifications

• Mount conversion: Pentax K lens to Sony NEX (E‑mount) camera
• Material and finish: metal construction with black and blue finish
• Mechanical features: precise flange focal distance correction for infinity focus
• Functionality: no electronic contacts; manual focus and manual aperture control
• Compatibility: designed for Pentax K lenses and Sony NEX/E‑mount mirrorless cameras

How to use

Attach the adapter to the camera’s E‑mount by aligning the marks and turning until it locks, then mount the Pentax K lens onto the adapter and secure it in place. Set the lens aperture manually if the lens has an aperture ring, or use the adapter’s f‑stop control ring if the lens lacks a manual aperture control. Operate focus manually on the lens and use the camera’s viewfinder or live view for composition and focusing. Since no electronic communication is provided, set exposure mode to stop‑down metering or aperture‑priority where supported.

Recommendations

For long or heavy Pentax lenses mounted on Sony NEX bodies, consider using an adapter collar (ASTAT‑NEX) or an external support to relieve strain on the camera mount and improve balance when shooting.
