Q: 4. Can you use the gels and grid at the same time?

A: The filter and gels for the Godox Standard Reflector with Filter Holder for AD300pro Flash Head are designed to be used one at a time. However, if you force them into place (which may cause damage) they will fit imperfectly.

Q: 5. Will this work with the Ad200?

A: This is designed for the AD300 and is not compatible with an AD200.

Q: 6. I want to know if this product works with godox AD400 Pro

A: No, the Godox Standard Reflector with Filter Holder for AD300pro Flash Head is not compatible for use with the Godox AD400Pro Witstro All-in-One Outdoor Flash. According to Godox, the AD-R14 is not deep enough for use with the AD400Pro. If you need a gel kit with a grid, the Godox Barndoor Kit for AD400Pro Outdoor Flash, B&H # GOBD08, would be the correct option for use with the Godox AD400Pro Witstro All-in-One Outdoor Flash. While a dedicated reflector is included with the purchase of the AD400Pro, if you need a standard reflector, the Godox Standard Reflector (7"), B&H # GOADR6, would be compatible for your usage needs.

Q: 7. Can it be used with pre G Nikon lens?

A: Yes, it would be compatible for use with Nikon F mount lenses. It states it is for Nikon G lenses as it has a built-in manual aperture ring to adjust the lens' aperture when using G lenses that do not have aperture rings. However, if you have a Nikon F-mount lens that has its own aperture ring, you may use that instead of the built-in aperture ring to control the lens' aperture.If you are instead inquiring about using the adapter with Nikon pre-AI lenses (such as those manufactured prior to 1977), then I have not seen any testing with these lenses and cannot guarantee they would be compatible for use with the above adapter.

Q: 8. What is the beam angle compared to the stock reflector included with the AD300?

A: The beam angle of the Godox Standard Reflector with Filter Holder for AD300pro Flash Head is approximately 60°.

Q: 9. What are the interior dimensions?

A: We would say the inside dimensions are approximately 3.5 x 4.5 .

Q: 10. it states G lens, is there a way to adjust aperature?

A: DEO-Tech states that the DEO-Tech OWL Nikon G to MFT Mount Drop-in Filter Adapter has a manual aperture ring built into the unit. As such, you would use the built-in manual aperture ring to adjust the lens' aperture when using Nikon G-series lenses on this adapter.
