Q: 1. 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: 2. Will this be compatible with the Fuji 18-55 kit?

A: As the Fujifilm XF 18-55mm f/2.8-4 R LM OIS Zoom Lens uses 58mm filter threads, the Sensei PRO 58mm Aluminum Lens Hood would fit onto the lens. However, as indicated under the Overview for the lens hood, it is designed for APS-C lenses that have a focal length of 28mm or longer, so there is the possibility of vignetting when using the lens set wider than 28mm (between the 18-28mm range of the lens). I would therefore recommend either using the dedicated lens hood that came with the lens, or consider the Sensei PRO 58mm Wide Angle Aluminum Lens Hood, B&H # SELHMW58, which is designed for APS-C lenses up to 18mm wide.

Q: 3. Will this fit the Lee 100 filter holder?

A: No, the Sensei Pro 58mm Adapter Ring for 100mm Aluminum Universal Filter Holder is not compatible for use with the LEE Filters Foundation Kit (Standard 4x4", 4x6" Filter Holder), B&H # LEFK. The Sensei Pro 58mm Adapter Ring for 100mm Aluminum Universal Filter Holder is designed for use with the Sensei Pro 100mm Aluminum Universal Filter Holder, B&H # SEFH100U. If you are looking for a 58mm adapter ring for the LEE Filters Foundation Kit (Standard 4x4", 4x6" Filter Holder), I would recommend either the standard LEE Filters 58mm Adapter Ring for Foundation Kit, B&H # LEAR58, or the wide LEE Filters 58mm Wide-Angle Lens Adapter Ring for 100mm System Filter Holder, B&H # LEARWA58, for your usage needs.

Q: 4. 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.

Q: 5. Can you use a lens hood with this?

A: Yes, you can attach a 72mm lens hood to this step-up ring. Here are two to consider. B+W 72mm #900 Rubber Lens Hood B&H # BWLHR72 and Sensei 72mm Quick Clip Lens Hood B&H # SELNQC72
