Q: 3. Can you put a UV filter on this GW-4 thingy? Thanks.

A: Unfortunately, the Ricoh GW-4 Wide Conversion Lens does not have front filter threads to accept a UV filter.

Q: 4. would this work on a canon vixia hf r700?

A: Hi, yes this lens includes a 37mm to 43mm adapter ring to mount on a camera like the Canon HF R700 which has 43mm lens/filter mount. For a lens that fits the camera without adapter rings, you may consider the Raynox HD-6600 Pro 43mm 0.66x High Quality Wide Angle Converter Lens BH #RAHD6600P43Z. I hope this is helpful.

Q: 5. Can I use this lens with a canon camera?

A: Ricoh GW-4 Wide Conversion Lens is a very small lens. Rear thread is only 49mm diameter. It would require a Canon camera that has a lens with 49mm filter thread for it to work.

Q: 6. Will this lens work with canon hf200

A: It looks like the HF200 will accept 37mm adapters and filters. Please confirm this. If so, the lens should work with your particular camera. I would look for vignetting as you adjust your shot as wide as possible. I have ran into this limitation with other (and wider) lens.

Q: 7. What is the diameter of the front filter thread?

A: You cannot use a threaded front filter on this lens.

Q: 8. does this lens work on a sony dcr-trv14e?

A: Unfortunately no. The Raynox HD-3035PRO Semi-Fisheye Conversion Lens with One Adapter Ring (0.3x, 37mm) will have a 37mm threading and the Sony DCR-TRV14E has 30mm filter threading. For attachment you will need a 30mm to 37mm step-up ring and the Sensei 30-37mm Aluminum Step-Up Ring (B&H # SESUR3037 MFR # SUR-3037) will work.

Q: 9. Will this filter kit fit on the SB-910? Thanks!

A: No, this only works on the SB-5000. For the SB-900 or 910, use the SJ-3 filter kit.

Q: 10. Does this work on sony ZVE10?

A: This conversion lens is designed to work on camcorders that incorporate a built-in lens but you can use it with select detachable lenses when paired with the Sony ZV-E10 camera. For example, a ZV-E10 with a 10-18mm f/4 OSS can use this Conversion Lens when paired with an adapter like the General Brand 40.5-37mm Step-Down Ring #GBSDR40.537. Other lenses would use adapter rings of a corresponding size.
