Mejora mi video con iPhone.
Me encanta este filtro, sobre todo porque tiene el aro magnético, permitiendo retirarlo y colocarlo rápidamente. Es genial usarlo con el iPhone y el case de Smallrig, sobre todo para controlar la luz a la hora de grabar video.

Worked great and portable but produces slight tinge
Works great and very handy to take off when I don’t need it. It does produce a slight tinge when in direct sunlight but nothing that can’t be fixed in post.

Quick and efficient swaps and no color cast.
Love the ability to magnetically attach on the fly, especially in dynamic lighting situations. I wish they made something like this for a full size matte box!

Great ND filter!
The filter works as intended. No issues or problems with video quality. Highly recommended!

Great quality VND at a great price
First, a note - this magnetic mounted filter is designed to work exclusively with SmallRig’s FilMov case system. If you are looking for a general purpose VND filter, keep looking. But if you are looking for great neutral VND with no cross pattern to add to your FilMov case - it doesn’t get much better than this. This system should make any budding filmmaker happy!

Nd filter came apart…
I wanted to move this filter to a different lens. The part that attaches to the lens first got stuck so I figured, I’d put the magnetic on top to help me twist it open. The lens element came apart! You can screw it back together but its misalign to where it doesn’t work well anymore.. cheap. Got what I paid for I guess. My first and last time buying magnetic lens filters.

Buen producto
Lo uso con el iphone 16 pro con la app de blackmagic y es indispensable en días de sol para aprovechar los otros parámetros. No deja marcas raras ni distorsiona. Muy cómodo de usar y el imán encaja bien y rápido.

Perfetto su iPhone
Il filtro funziona perfettamente su iPhone 17 pro, non vignetta e non presenta il fenomeno della X nemmeno con il 13 mm. Cinque stop possono bastare in quasi tutte le situazioni anche se con luce molto forte si potrebbe fare fatica a 1/50 dí secondo di shutter

Fair enough
Where the product might fall a bit short, considering it’s designed for a smartphone rig and not a professional camera, SmallRig itself shines both as a company and its representatives.
