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

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

Q: 10. Is the description backwards? This looks like it allows one to use a 72mm filter on a 67mm lens. Why would you use a filter that is smaller than the lens?

A: The description is correct; a step-down ring allows you to use smaller filters on larger-diameter lenses. There are a few reasons as to why, for example, to save on the cost of buying filters again if you already own a lot of them in the smaller size. Also, if the lenses have a very narrow field-of-view, the visible vignette might not be significant and not influence the photo that much.
