Designed specifically for the Canon RF 14mm f/1.4 L, this adapter brings NiSi's JetMag Pro MAXMAG magnetic filter system to an ultra-wide lens without a front filter thread. It addresses the filtration challenges posed by the lens's bulbous front element while preserving compact handling, making filters accessible for landscape photography, astrophotography, architecture, and wide-angle filmmaking.
- • Compatible with the complete JetMag Pro MAXMAG filter range, including circular polarizers, neutral density (ND) filters, Natural Night light-pollution filters, and creative-effect filters.
• The NiSi JetMag Pro MAXMAG filter system is sold separately.
The compact MAXMAG setup gives Canon RF ultra-wide shooters several ways to shape an image: ND filters support long exposures and video, circular polarizers help control reflections and deepen skies, and light-pollution reduction filters support astrophotography. Specialty filters add creative cinematic effects, extending the available options on a lens with otherwise limited front-filter compatibility.
Instead of screwing filters on and off, the MAXMAG interface uses a magnetic mount for quick attachment and removal. Filters snap into position and release rapidly, helping photographers and filmmakers respond to changing light or capture a scene before shooting conditions shift.
The adapter supports two MAXMAG filters at once without vignetting, even at 14mm. This allows combinations such as a circular polarizer with an ND filter for long-exposure landscapes, or a variable ND with a Natural Night filter for nightscapes and astrophotography, while keeping dark corners out of the frame.
- • To engage the filter lock, twist the filter until it lines up with the adapter's white mark, helping prevent movement or detachment during use.
• Stacked MAXMAG filters lock together when rotated until their handles align, adding stability in demanding shooting conditions.
• To unlock a filter, rotate its handle away from the adapter's marked line. Magnetic attraction continues to hold it in place until removal.
A precision clamping ring secures the adapter to the lens barrel and allows installation or removal in seconds. Once tightened, it provides a stable filter mount designed to resist flexing, rotation, and accidental movement during long exposures, time-lapse sequences, and video recording. The mechanism is built for repeated mounting and removal in both studio and outdoor use.
Genuine Alcantara® lines the adapter's interior contact surface. This synthetic suede serves two practical purposes: it increases friction for a secure grip on the lens barrel and cushions the painted finish against scratches, scuffs, and pressure marks. The protective lining is especially useful when the adapter is frequently installed and removed.
The body is machined from one piece of aerospace-grade aluminum to combine rigidity and long-term durability with low weight. Keeping the adapter light is useful when balancing the ultra-wide lens on a gimbal, slider, or tripod head, without sacrificing a sturdy foundation for the magnetic filter system.
A luminous position mark provides a visible reference for aligning the adapter in low light. It reflects brightly when illuminated, making correct positioning easier after sunset. This detail supports astrophotography, night landscapes, and location filmmaking, where finding the mounting reference quickly can help avoid delays while setting up equipment in the dark.
