Lens Attachment Raynox MSN-202, 25-diopter close-up, 12x–20x zoom, 37 mm thread, 60 g

Raynox MSN-202 is a clip-on close-up lens attachment that converts a standard lens into a high-magnification close-focusing optic. With a 25-diopter diopter value it provides a macro-capable working range equivalent to approx. 12×–20× zoom, enabling detailed photography of small subjects without the need for a dedicated macro lens. The unit attaches to lenses with a 37 mm thread and weighs about 60 g, making it simple to carry and quick to mount for on-location shooting. When paired with compatible camcorders it allows shooting very small objects from just a few centimetres away at long focal lengths.

Advantages

The Raynox MSN-202 improves close-focus capability while keeping size and weight to a minimum. Its 25-diopter optical design produces strong magnification for product, nature and detail shots, and the 37 mm mount ensures broad compatibility with many lenses and step-up rings. The lightweight clip-on form factor allows fast attachment and removal so you can switch between standard and close-up shooting without tools. The lens element is designed to preserve image quality at close distances and is suitable for handheld or tripod use.

Suitable for

• Macro and close-up photography of small objects
• Product and detail shots for online catalogs
• Nature photography of insects, flowers and textures
• Close focusing with camcorders and compact video cameras

Key specifications

How to use

Align the Raynox MSN-202 with the front of your lens and secure it using the 37 mm thread or compatible adapter; ensure the optical centers are aligned to avoid vignetting. Focus at the telephoto end of your lens and move closer or adjust zoom to achieve the desired magnification — the effective working distance will be short, so take care to avoid casting shadows or disturbing small live subjects. Use a steady support or tripod for best sharpness at high magnification and stop down the lens aperture if greater depth of field is needed. When finished, remove the attachment and store it in a protective pouch to prevent scratches.

Usage recommendations

For optimal results, use the MSN-202 at longer focal lengths on zoom lenses and pair it with a stable support or tripod. Consider using live view or focus peaking to confirm focus, and employ diffused lighting to minimise harsh shadows on small subjects.
