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. 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: 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. 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: 5. If I want to go from a 37mm lens to a 77mm filter would I stack all these rings together?

A: It is possible, however I would advise you to try using as few rings as possible to avoid vignette. As well, you will need to make sure that the filter you are using is absolutely clean to avoid focusing issues.

Q: 6. is this for general lenses? i have a canon 50mm (nifty fifty) will this work on it?
