Pixco Reverse Mount Macro Adapter Ring for Pentax to 58mm

The Pixco Reverse Mount Macro Adapter Ring for Pentax to 58mm is an adapter that allows compatible Pentax lenses to be mounted in reverse on a camera body while providing a 58mm external thread for filters or accessories. By reversing the lens, this adapter increases close-focusing capability and magnification, enabling macro and extreme close-up photography without the need for a dedicated macro lens. The adapter is a simple mechanical solution intended for photographers seeking an affordable way to experiment with high-magnification shots using existing Pentax lenses and standard 58mm accessories.

Advantages

This Pixco adapter offers a compact and lightweight way to convert standard Pentax lenses for reverse-mount macro use while retaining a 58mm thread for attaching filters or diopters. It is a cost-effective alternative to dedicated macro optics, easy to attach and remove, and compatible with any lens that fits the Pentax mount and can be safely reversed. The adapter requires no electronics, which ensures straightforward mechanical compatibility and consistent physical alignment for macro work.

Suitable for (tasks / use cases)

• Close-up and macro photography with compatible Pentax lenses
• Creative photography of small subjects such as insects, flowers, and textures
• Adding filters, close-up diopters, or protective glass via the 58mm thread
• Practice and experimentation with macro techniques without buying a dedicated macro lens

Key specifications

• Mount type: Pentax (reverse mount configuration)
• External thread size: 58mm for filters and accessories
• Construction: lightweight mechanical adapter for reverse lens mounting
• Compatibility: designed for use with Pentax-mount lenses that can be safely reversed

How to use

To use the adapter, detach the lens from the camera and mount the lens to the adapter in the reversed orientation, then attach the combined assembly to the camera body so the lens faces the subject. Secure the adapter and lens to ensure proper alignment. Because the lens is mounted in reverse, manual focusing and aperture control (if available on the lens) are required; metering and autofocus behavior may vary depending on camera and lens capabilities. Attach any 58mm filters or close-up accessories to the adapter's external thread as needed. Exercise care when operating near delicate subjects to avoid contact between the lens and the subject.

Usage recommendations

Use manual exposure settings and a stable support such as a tripod to minimize camera shake at high magnifications. Work with adequate lighting or a dedicated macro light and consider a remote release or mirror lockup (if available) to reduce motion. Verify that the particular Pentax lens you intend to reverse is safe to mount backward and handle it gently to avoid damaging the rear elements.
