Q: 1. Hi, I'm looking for softboxes larger than the Angler Silverboxes. So what brands of softbox with grid that's available from B&H and is compatible with this speed ring? Thank you

A: We do not recommend going any larger than 24 x 32", since the Angler Shadow Focus Light cannot hold much weight. A suitable softbox to fit the ring in question is the Impact Luxbanx Duo Medium Rectangular Softbox (24 x 32"), B&H # IMLBRDM. https://bhpho.to/38XUpmn

Q: 3. What is the correct size for the Sigma Art 50-100mm f/1.8 Lens EF focus ring?

Q: 4. Hi there. Could you please advise what the right size is for the Sony 100-400mm f4.5-5.6 is? It is not on the lens guide. The lens has a 77mm filter. Cheers.

A: With these, you have to measure the outside of the lens because they only give you the threaded diameter length; but the Sony 100-400mm f4-5.6 has around a 94mm outer diameter. You could try the 88-90mm version but I doubt it will stretch to 94mm.

Q: 5. Which ring size would fit for the Fuji 10-24 f/4? It has a different focus and zoom ring barrel diameter.

A: The one depicted here should work as it stretches to cover the necessary millimeters in difference.

Q: 6. It reads the item is 12" long, does it only make one ring or can you make more?

A: The Tilta Seamless Focus Gear Ring size for the 70-300mm Sony lens is gear model B&H # TITAFGR8183 https://bhpho.to/40mBR9i All the other lenses on your list would need to be measured for the correct size.

Q: 8. Do these work with the DJI Focus Motor and it's teeth? I have tried the Neewer and Smallrig versions and nothing has worked.

A: No, the Tilta Seamless Focus Gear Ring seamless rings are not compatible with the DJI Focus motors. seamless rings may not have long enough teeth for the motor to grip. We recommend using the following gears. DJI Ronin-S Focus Gear Strips (2-Pack) BH #DJGEARP19 • MFR #CP.RN.00000026.01

Q: 9. What is the correct size for the Sony FE 24-105mm f/4 G OSS Lens (it is listed incorrectly - I know because I purchased 2 and they are waaay too small)?

A: You should use the Tilta Seamless Focus Gear Ring (81 to 83mm).

Q: 10. Will this fit the Lumix Leica 10-25mm F/1.7 MFT and 25-50mm MFT lenses?

A: The Tilta Seamless Focus Gear Ring (88 to 90mm) would be right on the borderline, as both those lenses have a diameter of 87.6mm. I think you may be better off trying the next size down (85 - 87mm) instead, which would be a bit tighter but should provide slightly better performance.
