Q: 1. 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: 2. Is this m52 x 0.75 male thread? Also, what is the external diameter of this step down ring? Thanks

Q: 3. Does this filter allows to use a 67mm filter on 52mm lenses?

Q: 7. could i use this in nikon lens to step down to use with 37mm Firecrest Neutral Density 5.4 Solar Eclipse Filter (18-Stops)?

Q: 8. 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: 9. I'll be using this on my 85mm Tessar ZM which has 43mm filter thread. All of my filters (CPL and ND) have 39mm filter thread. Will my 85mm Lens vignette by using this item?

A: Anytime you use a step-down ring to use a smaller filter on the front of a lens with a larger filter diameter, you run the risk of obtaining some vignetting. Unfortunately, we have no way to test or guarantee which lens/focal length combinations. While vignetting would normally be more noticeable with wide angle lenses compared to telephoto lenses, I cannot guarantee you will not get vignetting. The best I can state would be to purchase the item and see if it works for your needs, and if it does not, you would have 30 days to return the item for an exchange or refund via our 30-Day Return Policy on this item.
