Q: 3. 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: 4. 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: 5. 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: 6. I have very very slim ring for the CPL filter (the ring that is close to the lens is extremely thin), will this wrench work? The CPL outside ring that rotates is about 2X thick of the insider ring though? Can this wrench grab both rings with the inside ring that is actually attached to the lens?

A: Haven't worked for me.

Q: 7. How much does this product weight?

A: According to our shipping specifications, the product will weigh .30 lb.

Q: 8. Are these Sensei Rubberized (ie. steel coated with rubber) wrenches worth the extra cost over the plastic ones? I'm asking in the context of 58mm filters, but also just in general.

A: Yes. I've had the plastic ones break. These probably won't ever break and the rubber coating is sticky and grabs the filter better. I own them in 3 different sizes. Definitely worth the extra cost.

Q: 9. Can it works for 82mm

A: No unfortunately, the set will only accommodate filters up to 77mm. We do not have any options that will work with 82mm sized filters.

Q: 10. If I have the 82mm thread, should I order 72-82 or 82-95 size?

A: The 72-82 will provide better grip
