[72 mm] Now I can use my Lee filters SW150 with more lenses, very happy

[5 x 4.95 x 1.3"] Sold built, and fits perfectly. There are no instructions on how this is suppose to go on the lense. It would be obvious if you have had experience with lee filter holder but took me a moment to figure out. I like this especially because to fit on Nikon 14-24mm lense you will have to take out the lense where as this just screws on to the front element.

[72 mm] I have been a fan of ultra-wide lenses for years.  This adapter has been extremely well designed for durability and ease of attachment.  So far, I am extremely pleased with the results, but I have not used any filters at the 7mm level yet.

[5 x 4.95 x 1.3"] This is completely compatible with the Zeiss Milvus 15mm /f2.8 lens, as tested on a Nikon D810 with the Lee SW150 Mark II filter holder. The adapter screws onto the lens and fits perfectly, leaving ample access to the focusing ring. The ring is very well made.�

The only downside of the ring is that the lens cap cannot be affixed to the front of the lens with this adapter ring in place. Lee makes a plastic cap that can go over the entire adapter ring for the smaller filter system, allowing the ring to be left in place in the field when moving the lens to and from your bag. No such product is made for this larger system.

To solve this one problem with the system, I carefully measured the filter adapter ring and 3D printed a plastic cap to go over it. This is probably a bit much for most people, but if you or someone you know is handy with a 3D printer and 3D design, it's not a hard thing to do.

Hope this helps. The Zeiss Milvus 15mm is an amazing lens, and this filter holder system is completely compatible with no vignetting. I use the holder system with Lee and NiSi filters.

[0.345 lb] I was concerned about the look and was not sure if it works well.When I saw it, it looks great works fine.It is easy to put it onto the lens thread and nicely fits into Lee SB 150 filter holder and looks great.
I love it and don't have to hold my Galen Rowell ND filter in front of my 95mm lens any more and now I'm using Lee SB150 filter holder for my other lenses using step up
rings.Another nice thing is that since I have 95mm circular polarizer attached to this 150-95mm ring, it's easy to put the Lee SB 150 filter holder to any sizes of lenses and I have one more slot available to stack second ND filter or other filter in my Lee SB filter holder.
Now I still use 150*150mm square Lee circular polarizer into the first slot of Lee SB150 filter holder and the Galen Rowell ND filter onto the second slot for my 14-24mm Nikkor lens.However, I have a second slot available free now since I could attach my 95mm Singh Ray circular polarizer onto the 150-95mm step up ring and don't need a 150*150mm square circular polarizer attached to my SB150 Lee filter holder any more, I have two slots available for filters.
And it is much better and convenient to use
otherwise a very bulky and big SB 150 filter holder with square large size ND filter(I use 150*225mm square Galen Rowell ND filter and it sticks out and needs to be used carefully)
But now I could use it for other lenses and don't have to hand hold ND filter anymore.
It works very nicely for me.

[Aluminum] I previously had a rigid-case filter holder that took up too much room in my backpack. This holder safely stores my 4x5 filters while taking up a fraction of the space of most other filter cases. Accessing and storing the filters is easy and the microfiber fabric can be used to clean the filters.

[72 mm] Lee makes the best Big Stopper, period.� Hitech is pure garbage, plastic cheap garbage unless they started to produce glass.� The Lee 150x150 and 100x100 however are both works of art, and to make it work on the 11-24mm, what other option is there?� Hitech makes something to fit around the lens hood? Sure, It's tough to install, I had to watch someone on youtube do it, but once you get it working, it's golden.

[72 mm] I first got the Lee SW150 system for my Nikon 14-24mm. This is a great lens for my landscape photography but the Lee system allows me to use only two filters (unlike the basic model that can hold 3 filters). Wanting to be able to use 3 filters myself without having to purchase the basic model and all new filters, I decided to buy SW150 Mark II Lens Adapter for my Nikon 24-70mm VR Lens. This adapter has been able to be threaded onto my 82mm circular polarizer. I can still rotate the polarizer, use my ND filters (little stopper and big stopper as well) and a ND Grad. There is no light leak or vignette on any of my images. There is a very tight fit when using the little, big, and supper stoppers and it feels like you could possibly scratch a filter if you're not careful. No scratches on my filters yet though. This purchase has made my landscapes pop since I can polarizer the water while I prolong the overall exposure and adjust for the sky!

[0.345 lb] Nice for my Nikon lens 200-500mm of 95 mm thread

[0.345 lb] I've had a harriet fix for a few years now, but this is great what the engineers have created. It works really well not only for the bigg stopper, but for all other filters too.
