A: The Voigtlander Nokton 17.5mm f/0.95 Lens for Micro Four Thirds Cameras has an outer diameter of 63.5mm. You would need the Tilta Seamless Focus Gear Ring (62.5 to 64.5mm) for this lens.

Q: 3. What size ring is good for sigma 18-35

Q: 5. 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.
