Xume MFXLA62 Lens Adapter 62mm, Black, Compact

I shoot video with a GX85 with a Panasonic 8-18mm (MFT) [16-36mm FF] that has a 67mm thread and use a brass step-up ring to avoid vignetting with a Freewell 77mm VND and the Xume adapters. No issues for video (both 1080p & 4K) , but it does vignette with photos (4:3), but I would think photographers would rather use fix NDs which would be thinner than most VNDs, in general.Not sure how these will hold up over time, but love the functionality. Just a mere second or two to pop on or off any filter with the matching adapter ring. In run-and-gun situations, it's comes in handy walking to/from a bright environment and popping on/off a VND and one great benefit is you can position the arrow on the VND so it's always visible. No more carefully threading and screwing on a filter and not having sight of the arrow when you need to be recording and trying to determine exact position for stopping down. Freewell VND has arrows on both sides, so that's less of an issue, but there are others that don't.Overall, great for my needs, but probably not for photographers with the same equipment.

Just what the doctor ordered. I just got this along with the filter holder, but so far, so good. They work as expected. This will allow me to change filters much more easily and quickly than the old-school thread system.I was concerned that they might be easily knocked off. It *could* happen if you bump into something at just the right angle, but the filter holder sits down into a recessed area in the lens adapter, so a lateral strike isn't likely to knock it off. The magnetic attraction between the two seems about right; not too strong for easy removal, but not so weak that it would be bumped off. If you're concerned about it, I'd recommend keeping the lens hood in place. The adapter and holder are designed to allow the lens hood to be put on and removed easily anyway, so the hood should provide adequate protection.I would definitely recommend this and the filter holder if you have a habit of switching filters often. They will save you a lot of time and hassle.

These rings hold the matching ring/filter pretty well although with another unit I did drop a filter off the lens onto some rocks. Bad things happened. But it is very convenient to use especially to swap ND filters in once a composition has been finalized. btw these rings will add some vignetting corners to wide angle lenses like a 24-70.For some unexplained and ridiculous reason this same item is selling for the price-gouging, usurious figure of 148.00 CAD. on the Canadian site- third part seller. Complaints have gone unanswered. So, in Canada buyer beware! 33.00 USD is much more reasonable. Amazon needs to be on top of and in control of third party sellers such as these.

These things aren't cheap but man the convenience they add to a camera is astounding. I do a lot of wedding videography where moving between indoor lighting and outdoor direct sunlight happens 100x on the day of filming. The Xume system is invaluable to me. When these are coupled with a high quality variable ND filter, it's so easy to quickly adapt to lighting changes and allows me to easily use one expensive filter on various cameras. Lots cheaper than buying a filter for each camera or lens. Highly recommend this system.

I really wanted to like this system, I had it all planned out. My clear and my circ PL would each have these, then I could add NDs on top as needed.Unfortunately I realized this system is unusable due to vignetting unless you use step up rings. The vignetting was so bad with the adapter + 1 filter on.I suppose that the users lens is also a factor as well, now I know that my Sigma 24-70 will tolerate 2 filters, barely, before vignetting is crazy. If your lens can tolerate 3 filters then you could skip the step up ring.So to summarize I think this system is awesome but only when using step up rings. If your lens is 82mm you are pretty much screwed since I think this is the maximum size of the adapters.

This product has been around for several years, from my best recollection. I've finally got around to trying it and can only say one word -- Wow! This is an excellent product and works, just as the company claims. I've bought enough for my two 77mm lenses. I'm going to purchase a unit for each of my lenses. It's a great investment.I have noticed some vignetting when mounted on my 16-35mm lens. The 24-70mm seems OK. I'll probably send back the unit that I purchased for the 16-35.

Simply put this adapter is of no use on a breakthrough ND filter. I have not tried it with any other brand.

Saw photographer using on Youtube, thought I would try a set. Now every lens that i buy get an adapter, Changing filters in the field could not be easier. Wide angles do vignette but not so much that a usable photo can be made. I use with a cokin setup for the square filters and it makes them easier to load in rough conditions.
