Fits perfectly

System with an excellent price/performance ratio. The filter holder system makes it easy to frame before installing the ND 1000 filter.

This is the UV filter that serves as the base of the magnetic system. Once this is installed, other magnetic filters can be placed on top of it. No need to turn it on and off, just snap it on and off. Filter changes in 1 second. Makes the workflow much easier, especially if you are in a busy shooting environment. The UV filter is very secure and very, very thin. Thin is good, but also makes it difficult to keep part of the lens cap on. It's not a big deal, but it's worth keeping in mind.

My wife and I travel a lot in a converted van that has a pretty competent solar-powered house electric system. We seldom camp in campgrounds with hookups, so we rely on the house system a lot. I bought this to have an easily portable alternative method for charging the many USB rechargeable devices we use in our travels - our phones, camera batteries, power banks, flashlights, etc. This has worked out very well in the short time I've had it. In the right conditions, it charges about as fast as plugging a device directly into the house system. It's compact enough to be easy to store, even in our very small camper. It seems to be very rugged, and, except for the USB interface, it seems pretty weather resistant.

in general I'm happy, but I spent half a day for installing and tuning it... In my case, I have to 3d print extra things for installation on the wall, because the angle of my wall is far from the south. anyway everything works as expected

The idea of a magnetic filter system is very good, in the set you get the mount, circular polarizer, UV filter and an ND1000 filter all inside a nice quality pouch to keep them safe. This set is ideal for the landscape photographers out there, the ND filter allows you to slow down the shutter speed to enhance the effect of movement, the circular polarizer allows the control of reflections. Overall a very handy set that will be a permenant part of my kit.

Seems very well built. Installing today.

System with excellent value for money. The filter holder system makes it easy to frame before installing the ND 1000 filter.
