Q: 1. 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: 2. 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: 3. 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: 4. 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: 5. 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: 8. What is the thread pitch for the 39mm side of the Sensei PRO 39-52mm Aluminum Step-Up Ring?

Q: 9. 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
