Related Questions and Answers

Q: 1. Would these be compatible with a Tiffen brand ND Filter? Thanks!

A: Yes, these Sensei step-up rings are compatible with Tiffen ND. I use 77mm Tiffen ND and use multiple of these rings with my different Canon and Panasonic lenses. I had bought both the Tiffen ND and Sensei rings from B&H and they work perfectly fine on my shoots.

Q: 2. If I have a camera with a 30mm lens, and a 37mm fisheye, do I need a step up or step down ring?

A: If your filter/attachment is larger than your lens, it's a step-up. In this case, your fisheye attachment is 37mm and your lens' front diameter is 30mm, hence, you'd need a step-up ring.

Q: 3. Would this work with tiffen Nds?

A: Yes, it's meant for any circular filters with 82mm diameter.

Q: 4. If I flip this around can I use it as a step-down ring? I know I'll have to deal with vignetting (well, maybe not technically vignetting, but overlap into the image area), but will it work until I can get the correct size filters? Or are the threads threaded in such a way that it can only screw on to the lens on one side and the filter on the other and cannot be flipped?

A: No, this can only be used as a step up ring.

Q: 5. Could this be used on a sirui 60mm portrait lens for smartphones?

A: No, that step-up ring will not fit. The Sirui 60mm Portrait Lens does not have threads to screw into.

Q: 6. Are both threads fine/standard or is the 95mm coarse like the Canon RF 28-70L and the 67mm fine?

A: The Sensei 67-95mm Aluminum Step-Up Ring has course 1.0 pitch threading on the 95mm side, and standard 0.75 pitch on the 67mm side. This is fairly standard for these sizes.

Q: 7. ok so I am planing on purchasing filter with 77mm thread and I want to also use it on a 58mm and 67mm threaded lenses so would the 58-77mm step up work for all 3 lenses? 67 being in the middle? Or do I need 2 separet step up filters? One 58-77mm and one 67-77mm

A: Dear friend, the reason to buy a bigger filter for smaller lens is to avoid vignetting at wide setting. For your case (filter 77mm / lenses 58mm and 67mm) you need two step-up rings. One from 58 77 and another from 67 77. To save one ring you must buy a 67mm filter and use to the 58 lens with step-up ring and as it is to your other lens (67mm diameter). I hope I have solved your problem.

Q: 8. Can this be used in a 114 Matte Box? Hypothetically want to take a Sigma Art Lens and used a Bright Tangerine Mistfit Atom.

A: The Sensei 72-95mm Aluminum Step-Up Ring allows you to connect a lens with a 72mm front thread to a 95mm thread adapter ring. Unfortunately, you cannot replace the adapter ring for the matte boxes with a step-up ring because they are designed as a proprietary system.

Q: 9. Can I purchase a 72mm filter and use that one filter on both a 72mm lens and a 46mm lens with the 46-72mm step-up ring?

A: Yes, that's exactly what it's for.

Q: 10. I have never used step rings before and am just wondering can they be stacked to use 62mm filter on 52mm lens? Or is there an other option I should consider. Does stepping up like that increase the chance of lens damage considering the filter extends wider than the barrel?Thanks

A: Yes, they work just fine. I would echo the caution on internal reflections.
