Q: 1. I am thinking about purchasing an 82 mm neutral density filter. Is a step-down ring what I need to allow me to use this filter on my 77 mm lenses? Looking at the 82-77 step-down ring (#408) by Heliopan. Thanks!

A: What you would need is a step up ring instead, since you are trying to fit an 82mm filter on a lens with a 77mm diameter. Please see the following link: http://bhpho.to/1n8QhUq

Q: 2. what is the thread pitch?

A: Heliopan does not list the pitch on the Heliopan 42-39mm Step-Down Ring (#316). But standard for that size is 0.75mm thread pitch.

Q: 3. I have a Canon 24-70mm ef L lens f.2.8 uses 82mm filter. I want to step down to myCanon 24-105mm ef L lens with 77mm filter will this step down ring work?

A: It depends... If your camera has an APSC-size sensor, it will probably work. On a full-frame, it is very likely that you will end up with dark corners at the wide end, because at 24mm the lens has a wide view, and the step-down ring + the filter will extend too far forward and cause vignetting. Best way is to hold your filter about 3-4mm in front of the lens and see if it does cause vignetting.

Q: 4. Are the threads female on both sides?

A: No. The 58mm side is male and screws into the lens. The 49mm side is female and receives the filter's male threads.

Q: 5. Can multiple step down rings be used at same time to achieve desired use. For example, assuming one ring in size needed does not exist, can I use a 77mm to 72mm + a 72mm to 68mm at same time?Tks.

A: You could use multiple step-down rings together if the combination you need isnt available. I would suggest using more than two together. Also keep in mind that using a filter that is smaller than the filter thread of a lens can cause vignetting. So you wouldnt want to use a filter that is too much smaller than your lens.

Q: 6. Will these fit on a Canon lens?

A: This General Brand Step-Down Ring Kit would be compatible with Canon lenses, but it depends on the filter size of the lens.

Q: 7. Does the difference in thread sizes cause noticeable vignetting on wider focal lengths?

A: Very possibly, yes, it depends on the focal length of the lens, how wide it is. It always best to get a larger filter if possible. Putting a smaller filter, especially on a wide angle lens, is a recipe towards vignetting.

Q: 8. What is the overall diameter of this step-down adapter ring?

A: There are no published measurements of the diameter of the Heliopan Bay 1-30.5 Step-Down Ring (#305).

Q: 9. Does this cause heavy vignetting with prime lenses for example 50mm?

A: No, you should not get vignetting with a 50mm lens.
