Nisi JetMag Pro Back Cover (49MAG)

The NiSi Back Cap for JetMag Pro 49MAG protects the back of compatible 49MAG filters during transport. For photographers, videographers, travelers, and content creators, this magnetic back cap is a compact accessory for safe filter storage.

Rear Protection for JetMag Pro 49MAG Filters

The back cap attaches to the back of compatible JetMag Pro 49MAG filters and protects the optical surface when the filter is not mounted on the lens. With magnetic filter systems in particular, filters are frequently swapped out, temporarily stored, or carried in a bag. Without a proper cover, dust, fingerprints, moisture, and small scratches can damage the coated surfaces. The NiSi rear cap for JetMag Pro 49MAG reduces this risk and keeps the back of the filter cleaner until it is used again. This is particularly useful for photographers and videographers who quickly switch between ND filters, CPL filters, mist filters, or other 49MAG filters. The cap is thus a small but important accessory for a well-organized filter workflow.

Magnetic attachment with a secure locking mechanism

The back cap uses the JetMag Pro magnetic attachment system and snaps quickly onto the filter. The patented locking mechanism secures the back cap more securely than a simple clip-on cap and prevents it from coming loose during normal transport. This is useful in a camera backpack, in a caddy, in a jacket pocket, or when moving between shooting locations. Anyone who works quickly on video shoots, news reports, or YouTube productions benefits from a solution that requires no screws yet still fits securely. The tabs on the cap and filter align to lock them together, allowing the back of the filter to be protected quickly. This preserves the magnetic workflow without compromising the protection of the filter surfaces.

Flat Metal Housing for Compact Filter Storage

The NiSi rear cap for the JetMag Pro 49MAG is made of durable metal and is designed for regular use in the field. During quick filter changes, the backs of filters can more easily bump into other accessories, especially when working in tight pockets or under time pressure. The robust construction better withstands such stresses and protects the filter from everyday bumps. At the same time, the profile remains slim so that covered filters can be stowed away in a bag or caddy to save space. This makes it easier to transport multiple protected filters in an organized manner without taking up unnecessary space in your camera gear. This is an advantage for travel, landscape, event, and social media productions, as a small filter kit remains well-protected and ready for quick use.

Can be combined with the Front Cap for all-around filter protection

The rear cap can be combined with the JetMag Pro 49MAG Front Cap to seal a filter at both the front and back. This solution is particularly useful for transport, extended storage, or use in a filter caddy when multiple filters need to be protected separately from one another. The NiSi rear cap for the JetMag Pro 49MAG is compatible with every JetMag Pro 49MAG filter and can therefore be used flexibly with various filter types within the system. A single replacement cap thus covers different filters in the 49MAG workflow. For content creators, photographers, and videographers, this provides a simple way to keep nano-coated filter surfaces clean and free of contact marks. This extends the practical lifespan of the accessory and ensures that filters remain ready for immediate use when needed.
