Q: 1. If I buy an 82mm wide adapter ring, can I use it with an 82-77mm step-down ring to use on my 77mm lenses?

A: If the lens is smaller than the filter (77mm lens - 82mm filter ring) then it's a step-up ring rather than a step-down ring. But yes, using a step-up ring this adapter will work with your 77mm front-diameter lens and will allow you to mount the Lee 100mm system filter holder.

Q: 2. Does anyone just buy this adapter ring, and buy cheaper step up rings for your lenses with smaller front diameters? Essentially making all of your smaller lenses a 82mm front thread so you don't have to buy a bunch of $55 adapters?

A: This solution works if you're not attaching the adapter ring with a step-up ring to a wide-angle lens. I your lens is 18mm or wider on a full-frame, you may get vignetting on the corners. You should buy the wide-angle adapter rings for any wide-angle lens you have and cheaper step-up rings for your other lenses. Of course, this isn't as convenient as having an adapter ring on every lens.

Q: 3. I'm a little confused by this adapter ring. I thought it would have threads to screw into my lens. So no threads...do I just slip it onto the lens? Doesn't seem very secure. It fits in the filter holder just fine..just a little unsure of how to attach it to the lens-Tokina 11-20 mm which takes 82 mm filters

A: use the 82 MM non wide angle Lens it works fine on tokina 11-20

Q: 4. Will the sensor still 'see' the laser and its effects? I want to record a 5mW laser being 'split' by a prism.

A: You will unlikely see the laser effect when using the Kase Wolverine Magnetic 82mm Anti-Laser Protective Filter with Adapter Ring. From the information that we have, this filter is needed for lasers that are 10 watts or higher. You do not need this filter when using a 5-milliwatt laser unless it is pointed directly at the camera.

Q: 5. Will this work with the new Sigma 24 -70 2.8 DG OS HSM art lens? It is 82mm.

A: Yes, the filter sizes are the same.

Q: 6. Is it interchangeable with Ice 82mm Adapter for Haida 150 Series Filter Holder ?

A: No, the LEE Filters SW150 Mark II Lens Adapter for Lenses with 82mm Filter Threads is not compatible on the Haida 150 Series Filter Holder. This is the correct one for that holder, https://bhpho.to/3069dNr.

Q: 7. Is the adapter ring compatible with the older holders (the one with the brass knob)?

A: Yes, this Lee 82mm Wide-Angle Lens Adapter Ring can work with the Lee Foundation 100mm holder which has the brass knob on the side.

Q: 8. Will this work with the S5 filter holder?

A: Yes, it can. According to NiSi's website, "a NiSi S5 150mm Filter Holder can then be placed over the adapter ring. Please note: If using this adaptor with the previous generation S5 system, ensure S5 circular filters are used with the S5 holder." https://bit.ly/2Lh1BTB

Q: 9. If I have the choice to buy the 82mm Wide Angle Adapter Ring and the 82mm regular ring, why would I not use the 82 wide angle adapter ring? It is only $3 more and it will work on all lenses wide angle or not. Can't I use the wide angle 82mm adapter ring on all lenses?

A: Yes you could use the wide adapter ring on all lenses with a 82mm front filter thread. The wide angle adapter ring has a recessed thread witch allows a filter holder to be mounted closer to the lens therefor reducing the chance of dark shadows in the corners of a image. check out a video on you-tube by Joe Cornish for Lee Filters for more info.

Q: 10. Can I use this adapter with Fujinon GF23mm f4 lens?

A: Yes, it will work.
