 p.1 #16 · Breakthrough Photography finally launched their new magnetic filter system | |

I've not used magnetic filters and have been eyeing them for a while. I believe with the Breakthrough system, you would have screw the Magnetic Adapter Ring into the step-up ring and leave it on. You would likely want to buy a Mag Adapter Ring for every step-up ring you required. While this isn't a requirement, it would save you from having to thread the Mag Adapter Ring on to a step-up ring each time you wanted to use a magnetic filter. This all leads me to the reason that I haven't switched to magnetic filters.
The magnetic filter set that you buy will be for the largest size filter that you require, e.g. 77mm, 82mm. So for quick filter changes, I need to have a step-up ring mounted to every lens that has a smaller filter size. This takes up extra space in my pack (the wider diameter front end of the lens) and also prevents me from using the OEM lens hoods. With other magnetic filter systems, you just have a step-up ring with threads on the small size that threads into your lens and magnetic on the wider side of the step-up ring so the mag filter just goes right on. When Breakthrough, you will need to buy an extra magnetic adapter to go on to the wide side of the step-up ring.
What I want is a magnetic filter system that is designed such that the step-up ring is magnetic on BOTH sides (double mag step-up ring) and that also has a magnetic adapter ring (mag one side/threads on the other). All the companies provide the latter (mag adapter ring), but nobody does the former. With this type of system you would leave the magnetic adapter ring threaded into your lens always. For smaller lens, the double sided mag step up ring would quickly snap on/off to the lens as would the mag filter to the double sided mag step-up ring. For your largest diameter lens, you don't use the double-mag step up ring. ...Show more →
I think the new Maven Wave 3 has what you’re speaking of? Sizes for step up start at 72 though, however they also have step-down rings in the same style (magentic on both sides), that could go some way to helping that situation for certain focal lengths that that won’t cause vignetting.
In their full video for Wave 3 they mention someone already having a patent (perhaps on a better solution?), I’m really not sure, but they said they had to work around it.
I guess I’m failing to see what the better option would be, as what you’re suggesting seems like the ideal. If I could put a magnetic adapter on the lens in it’s native size, then just slap on magnetic step-up rings, I don’t have to leave step-up rings permanently attached to my lenses, which I, like you, don’t want to do, and if you don’t then the appeal of a magnetic system is dramatically lessened.
Everyone seems to say magnetic is a game-changer though, so perhaps I’m missing something.
It’s very odd that Breakthrough doesn’t offer step-up rings for the new system. I don’t know if it’s intended that we just use their current step rings?
I wonder if the Xume/Manfrotto rings are the ones with the patent impeding other makers, but that doesn’t seem like it, but I’ve seen it mentioned.
It’s all quite confusing.
Breakthrough has a history of company drama, instability, and lack of stock, and threads getting stuck, that makes me want to steer clear.
Some of the companies inlaid rings are interesting, but seem for most to have a risk of getting stuck, and limited compatibility with certain lenses and other system features. Hudson Henry mentions that he recommends skipping using them.
