## Long description

The Macro Reverse Mount Adapter JJC for Pentax lenses — 49mm thread is a mechanical accessory that allows you to mount 49mm-filter-thread lenses in reverse on Pentax camera bodies to achieve high-magnification close-up and macro images. Designed for photographers who want to experiment with close focusing using ordinary lenses, this adapter converts a standard lens into a simple macro solution without electronic contacts or focusing helicoids. It is compact, lightweight and intended as a cost-effective way to explore detailed shots of small subjects, product details and textures.
Advantages
The adapter provides a straightforward mechanical connection between a 49mm-thread lens and a Pentax mount camera, enabling increased magnification by reversing the lens orientation. Its construction emphasizes compactness and low weight, making it easy to carry and fit into existing kits for experimental photography. Because it is purely mechanical and has no electronic circuitry, the adapter is durable, simple to use and compatible with a wide range of 49mm-thread optics that can be reversed for macro work.
Suitable for
Close-up and macro photography of insects, flowers and small objects
Product photography and detailed texture shots for online listings
Hobbyist and experimental photography where a dedicated macro lens is not available
Studio and controlled-light setups requiring high magnification at short working distances
Key specifications
Mount type: Pentax camera mount on body side
Lens side connection: 49mm filter thread for attaching reversed lenses
Material: metal and/or durable alloy construction for secure mechanical fit
Functionality: purely mechanical adapter; no electronic contacts or autofocus support
Size and weight: compact and lightweight for easy transport and handling
How to use
To use the adapter, thread a compatible lens onto the adapter by its 49mm filter thread with the lens mounted reversed, then attach the adapter to the Pentax camera body as you would a regular lens. Set the camera to manual exposure modes and use either manual focus (if available on the lens) or focus by moving the camera and subject relative to each other; because there is no electronic communication, aperture control must be performed using the lens’ aperture ring if the lens provides one or via stop-down methods. Use a tripod and live view where possible to compose and achieve precise focus at very shallow depth of field.
Usage recommendations
For best results, use lenses with good close-focus characteristics and a visible aperture ring for manual control. Work with stable support, controlled lighting, and a remote shutter release or camera timer to minimise movement. Be aware of short working distances and adjust subject positioning accordingly; extension and focusing rails can improve precision when composing high-magnification shots.
