The Sensei Pro 77mm Adapter Ring for 100mm Aluminum Universal Filter Holder is designed to enable the use of a Sensei Pro 100mm Aluminum Universal Filter Holder on a lens with 77mm front filter threads. Grooved edges along the outer rim of this adapter ring allow the compatible filter holder's alignment teeth to fit, which helps to ensure optimal positioning of the holder and the filters placed within it.

Aside from 77mm rear male threads which allow it to connect to a lens, the Sensei Pro 77mm Adapter Ring for 100mm Aluminum Universal Filter Holder also features 86mm front female threads. That feature enables this adapter ring to accommodate a thin, 86mm round filter when used along with the Sensei Pro 100mm Aluminum Universal Filter Holder. If a thin, 86mm round filter is used on the Sensei Pro 77mm Adapter Ring for 100mm Aluminum Universal Filter Holder, the rectangular filter slot closest to the rear of an attached Sensei Pro 100mm Aluminum Universal Filter Holder becomes unavailable. If a filter holder is not attached, the Sensei Pro 77mm Adapter Ring for 100mm Aluminum Universal Filter Holder may be used as a step-up ring, permitting the use of thin or standard 86mm round filters on lenses with 77mm filter threads. This adapter ring features a lightweight, aluminum-alloy construction that has a corrosion-resistant, black anodized finish for durability. A plastic case is included for transport.

Q: 1. Hi. My original plan was to use the Lee Big Stopper; with a Cokin z-Pro holder on my Bower 14mm D700 combination. I read on the Big stopper Q&A that the Cokin cannot take 4mm filter. So now I'm opting for this Lee Foundation Kit.The next challenge is a adaptor ring. This is difficult as the Bower has no thread. I have machined my own aluminium adaptor Ring with an outside diameter of 101mm; which slides into the filter holder; securing it. The other end is a slide-fit over the lens body with securing bolts.So; are there any comments on this combination of gear? the 4x4inch filters would work fine on a lens this wide?I just want to make 100% sure before I order.I'm interested in Long Exposure Landscape shots

A: The Lee Big stopper is not 4mm. It is 2mm thick.

Q: 2. Does this work on the sigma 14-24 2.8 GD HSM as well???

A: This is only for the nikon AF-S 14-24mm f/2.8, but alternatives exist that support the Sigma 14-24mm f/2.8 DG HSM. For example: https://bhpho.to/3pdtATV

Q: 3. I have this filter to use with my 14-24mm and consistently get lens flare circles on long exposures. I have the view finder covered, so light is not leaking in that way. It occurs in pretty much all light conditions other than cloudy dusk (i.e. bright light from any source no matter if the source is in the front, rear or side of the camera). I have the filter in the closest slot to the lens, as instructed. Does anyone else have this issue and how do you prevent it?

A: You could try using the Flex Lens Shade to prevent flare.

Q: 4. Can I use this on a Nikon 10-20mm f/4.5-5.6G VR?

A: Yes you can. It just requires an adapter ring which would be 72mm for the lens in question. Lee is a great system. You'll love it.

Q: 5. I have 95mm lens thread. Does the foundation kit works fine?

A: Yes. As mentionned below you need the 95mm adapter ring: LEE Filters 95mm Adapter Ring for Foundation Kit.

Q: 6. Can you or how can you use a polarizing filter with this holder and does it have to be a lee filter?

A: You can use a square polarizer like this one:LEE Filters 4x4 Circular Polarizer Glass FilterB&H # LECP44 Mfr # PLC-GIt can rotate by spinning the entire holder. Most other 4x4 circular polarizers will work ,also.

Q: 7. Will this filter holder attach to my canon 24-105mm f4 lens? My lens takes 77mm filter threads. Or do I need to buy an adapter with it?

A: Yes you will need the 77mm adaptor. You will need an adaptor sized to each different lens size in your bag. Watch out for the wide angle vs standard as well. Wide angle adaptors allow the filter to sit closer to the camera to avoid blocking view.

Q: 8. I have a full frame Nikkor AF-S 17-35mm f2.8D. With 2 - 4x6 filters installed in this foundation along with the Lee 77 mm W/A adaptor, will I get any vignetting issues when shooting at widest angle?

A: Yes, you will have vignetting issues. You can crop it out, but it's a waste of pixels. I am absolutely torn as to whether to buy a 17-35mm or not because of this.

Q: 9. What do I need other than a wide angle adapter to be able to use 77mm CPL with this, does the tandem adapter need extra adapter to mount on the holder?

A: If you have one LEE Filter Foundation Kit, you'll need a second one to hold the tandem adaptor. If not, you'll save a few bucks by buying the complete kit (with two tandem adaptors).

Q: 10. Is this all you need to get the filters attached or do you need any other adapters? I saw on the Lee SW150 you need the holder and an adapter, Thanks..

A: you dont need anything else since this only fits the Nikon 14-24mm. Lee SW150 has adapters to fit different lenses.
