It has large side knurls to provide a more textured grip when mounting or removing it from a lens. This step-down ring features a lightweight aluminum alloy construction with a corrosion-resistant, matte black, hard-anodized finish for durability and minimizing reflections.

Q: 1. Hi. I just wanted to confirm the following: I have a 77mm 6 stop ND Filter that I want to use on 72/67/62/58/52/43mm lenses. Am I correct in saying that I am looking for a Step-Up Filter Holder (eg 72-77mm)? I need to confirm as I need buy a few of these. Also will you get vignetting when using these filters? Thanks.

A: Yes, you need to use individual step up filters for all your lenses. I use 5 step up filters for all my lens sizes to fit 77mm ND filter. 72-77mm, 67-77mm , 58-77mm, 49-77mm

Q: 2. Can anyone tell me the outer diameter of the 77mm step up ring(s) ? I'm interested to know if I can use a 80mm push on cap over it.

A: The OD is probably 79 or 80mm. You will have to try it with your cap, This is never an exact science due to the fact that dimensions are never precise from cap to cap and ring to ring.

Q: 3. Does this come in a protective plastic case that you can use to store it?

A: I'm sorry, no.

Q: 4. Hi, I want a metal lens hood for my Nikon F 24 f1.8 to avoid vignetting. Should I go for the 72 mm or 77 mm with stepup-ring, or something else? Best regards from Erwin

A: You may use the Sensei PRO 72mm Wide Angle Aluminum Lens Hood for a Nikon AF-S 24mm f/1.8 lens to prevent vignetting.

Q: 5. Does anyone know if this will work with a Lee 100mm filter holder?

A: No, this ring is specifically for the Sensei 100mm Filter Holder: https://bhpho.to/2MPKFSB

Q: 6. Can you stack these? I have a 58-77 but I want to convert it to an 82mm. Can I buy a 77mm to 82mm and stack it with the 58mm to 77mm?

A: You can do that, but vignetting is possible on a wide-angle lens--this 58-82mm adapter ring is a better idea: https://www.bhphotovideo.com/c/product/1443406-REG/sensei_surpa_5882_pro_58_82mm_step_up_ring.html

Q: 7. Am planning to do these 1. step up from 37-52mm and then 2. step up from 52-67mm 3. Mount a 67mm CPL filter Will I be introducing vignetting in this setup? Appreciate all comments. Thanks in advance.

A: Depends on the lens you're using. But its likely you wouldn't get any vignetting from the filter due to the filter being so much bigger than the lens diameter. A random suggestion I think would help to simplify the process, consider looking into this step up ring. It's from 37-67mm all in one. So you wouldn't need to stack step-ups. https://www.bhphotovideo.com/c/product/1355342-REG/benro_dr6737_67_37mm_step_down_ring.html?sts=pi&pim=Y

Q: 8. Will this work with the Lucroit 100mm Filter Holder??

A: Perfect fit.

Q: 9. Any vignetting? I would be using 37mm macro filters on 46mm lenses. Thanks!

A: Regarding the Sensei PRO 46-37mm Aluminum Step-Down Ring, yes, using 37mm on a lens with a 46mm diameter may cause vignetting.

Q: 10. What is the difference between this one and SESDR7767 which is the same brand but doesn’t have “pro” in the name?

A: The Pro has knurled edges for a better grip and corrosion resistant aluminum alloy.
