Related Questions and Answers

Q: 1. Could this cause vignetting on a 15mm wide angle lens?

A: While it would depend on the lens and filter you are using to say for sure, since this is a step-up ring and even wider, it is unlikely that it would cause any vignetting.

Q: 2. Will the Sensei step up rings work for freewell magnetic filters?

A: Since the ring is aluminum, it is not magnetic. The Freewell Empty Magnetic Base Ring (82mm) would still be needed in order to attach their other magnetic filters. https://bhpho.to/3hEadRN

Q: 3. Will this work with a Sigma 18-35mm f 2.1 lens?

A: If you are referring to the Sigma 18-35mm 1.8 lens, yes the lens has a 72mm thread and so the step up ring will allow you to use 77mm filters.

Q: 4. 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.

Q: 5. Is it made in japan?

A: This ring is made in China.

Q: 6. 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: 7. Will this fit a Fuji X30?

A: No, the Sensei PRO 40.5-52mm Aluminum Step-Up Ring will not fit the front thread of the Fujinon X30 camera because the front thread of the non interchangeable X30 lens is an unusual 40mm, not 40.5mm. The FUJIFILM X20 Lens Hood and Filter Set for X10, X20, or X30 Camera: https://bhpho.to/2WTA0sh features a step up ring 40mm to 52mm. It is the only step up ring that will fit the front thread of the Fujinon X30 lens.

Q: 8. 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: 9. Any vignetting? I would be using 37mm macro filters on 46mm lenses. Thanks!
