Nisi JetMag Pro 40.5mm Adapter Ring (49MAG)

The NiSi JetMag Pro 40.5mm Adapter Ring (49MAG) makes 40.5mm lenses compatible with magnetic 49MAG filters. For photographers, videographers, travelers, and content creators, this adapter ring provides a compact solution for quick filter changes.

Integrate 40.5-mm lenses into the JetMag Pro 49MAG system

The adapter ring screws directly onto lenses with a 40.5-mm filter thread and connects them to the JetMag Pro 49MAG magnetic system. This allows compatible filters and caps to be magnetically attached, removed, and quickly swapped as needed. Compared to the traditional method of screwing in individual filters, this solution saves time and reduces the risk of stripped threads. It helps maintain a smoother shooting workflow, especially in changing light conditions, during outdoor shoots, or when recording video. Once mounted, the ring can remain on the lens and serve as a permanent interface for the magnetic filter workflow. This transforms a compact lens with a 40.5-mm thread into a practical platform for JetMag Pro 49MAG filters.

Magnetic Filter Change with Secure Locking Mechanism

The magnetic attachment is designed for quick, repeatable filter changes. A white alignment line helps ensure the patented locking mechanism is closed correctly, so filters or caps sit securely. This is especially important during handheld shots, gimbal movements, windy conditions, or on uneven terrain. The NiSi JetMag Pro 40.5mm adapter ring (49MAG) is therefore ideal for photographers and videographers who need to switch between ND filters, CPL filters, mist filters, or protective caps without spending time screwing them onto the lens. For YouTube, vlogging, and social media productions, faster access to the right filter is a clear workflow advantage, as lighting conditions and subjects are often only available for a short time.

Slim aluminum design for compact lens setups

The ultra-slim profile is designed to minimize mechanical vignetting as much as possible. With compact prime lenses, wide-angle lenses, or small travel zooms, the low-profile design helps reduce dark corners in images caused by adapter parts that protrude too far. The precision-machined aluminum construction keeps the ring lightweight, stable, and dimensionally stable over time. At the same time, the lens setup remains slim enough for travel, street photography, landscape, photojournalism, and mobile video rigs. Users with multiple lenses featuring matching filter threads can equip each lens barrel with its own adapter ring and flexibly share the same 49MAG filter set. For content creators, this results in a lighter kit with fewer duplicate filters and a more compact packing size.

Compatible with JetMag Pro 49MAG filters and caps

The NiSi JetMag Pro 40.5mm adapter ring (49MAG) works with the 49MAG filter ecosystem. This includes compatible FS ND filters, True Color CPL, Black Mist, Pure Mist, diffusion filters, black-and-white filters, variable ND filters, as well as matching magnetic front and rear caps. The ring thus serves as the foundation for using a single filter system across multiple compact lenses. Instead of carrying different filter diameters, a unified magnetic workflow can be established. This simplifies use in the field, during rapid changes in lighting conditions, and in productions involving multiple focal lengths. For photographers, videographers, and hybrid users, the adapter ring is a small but essential accessory for a consistent JetMag Pro 49MAG setup.
