This set of four filters from K&F Concept are the first not mounting accessories I have for my Insta350 Go Ultra. They take advantage of the Go Ultra’s screw on and off lens filter system. I went for the 4 pack with CPL, and 3 ND filters in 8,16 and 32. The filters are all significantly larger than the one that comes with the Go Ultra (this does mean the original lens cover rattles around in the filter box.) The biggest surprise was the CPL filter had a rotating element letting you dial in the polarising in; and it works well. The ND filters are a good range for an action camera, especially if you aren’t using them in the gloom of October. They all have a good even density grey across the filters, and they didn’t introduce a significant colour tint in my video footage.Thanks to the screw on and off design the filters are easy to use; the high-quality glass in the filters helps them a great solution for the Go Ultra. The CPL makes reducing haze and reflections in footage easy. The ND filters are great in bright light and make a handy pocket camera give better footage in more lighting conditions.

Great, especially when filming during a bright day.Allows you to capture much better lit footage compared to the highly over exposed to shadow ratio you’d get without an ND filter. Use ND32 when it’s super bright out to ND8, when not so bright. You also get a circular polarising filter or CPL, which helps to cut reflections from shooting through glass surfaces or into a stream for example, which cuts those surface reflections on the water. For that beautiful, clean, delectable, imagery. Say you are on holiday in the Bahamas, a CPL filter on your Insta360 GO Ultra will help you capture the gorgeous waters without all those reflections stopping you from seeing whatever is swimming below.Or towards the camera when filming underwater (which I’ve not tested, how tight the threading is to prevent water penetration between this and the GO Ultra front lens).

This latest assortment of filters from K&F is aimed at the Insta360 Go Ultra user and arrives well presented in printed packaging bearing the K&F branding.The set of 4 filters, ND8, ND16, ND32 and CPL, are safely housed within a handy plastic case, ensuring their protection and also included is a small cleaning cloth.The filters are the usual K&F high quality and are very light in weight but also easily attach onto the Insta360 Go Ultra snugly and securely.The range of ND filters will cover just about every possible lighting scenario that you will encounter in your action camera use and will enable you to select appropriate shutter speeds in brighter conditions, while the CPL filter will allow the minimising of reflections in most conditions.All in all, the filters are user-friendly and easy to install, delivering impressive results with the usual high-quality K&F optics.Very good value comprehensive set of filters at this price point.

A splendid filter set for the Go Ultra, all neatly packed into a single case.My go-to is the CPL, as it gives more control over reflections, though it’s great having a solid range of ND filters as backup.They fit the Go Ultra perfectly, just as you’d expect, and the clear markings make them quick and easy to identify.

I picked up the K&F Concept ND/CPL filter kit for my Insta360 GO Ultra and honestly I’m pretty impressed with what you get for the money. The filters feel solid and well-made – the aluminum alloy frames don’t feel cheap or flimsy, and they thread on smoothly without that “gritty” feeling you sometimes get with budget filters. The glass itself looks clean, with no obvious color casts or imperfections, and the multi-layer coating seems to do its job keeping reflections and flare down.Out in the field, the ND8/16/32 options give a nice spread for different lighting conditions, letting me keep shutter speeds in check without blowing highlights. The CPL is a nice bonus, especially when shooting around water or reflective surfaces – it really does help cut down glare and make colors pop a bit more.In terms of image quality, I haven’t noticed any serious loss of sharpness or weird tints. There’s a very slight darkening around the edges with the stronger ND filters if you really push them, but nothing that ruins the shot, and it’s kind of expected at this price point.For value, I think this kit hits the sweet spot. You get four very usable filters in one package, with decent build quality and coatings, at a price that’s way less than some of the “big name” filter brands. For casual and even semi-serious shooting with the Insta360, they do the job really well.

These screw straight onto my Insta360 Go Ultra and replace the original protective lens with a snug, secure fit. Alignment is easy, and image quality stays clean. Reflections are low, and I have not seen any colour cast. The set includes a CPL plus ND8, ND16, and ND32. Swapping to ND when I change frame rates keeps exposure under control. Motion looks smoother, and highlights no longer blow out.The frames are made of lightweight aluminium and feel well-finished. A cleaning cloth comes in the pack.I have not pushed them in every condition yet, although so far they have behaved well in mixed light. Remember that ND filters want light, so save them for brighter days.Pros- Confirmed compatible with Insta360 Go Ultra- Screw-in design replaces the stock protector neatly- CPL, ND8, ND16, ND32 cover most bright-day needs- Low reflectivity and no obvious colour shift- Lightweight aluminium frames- Good value as a bundle- Cleaning cloth included
