Interesting and useful video. Thank you for sharing. I recently purchased one of these lenses. Externally it is like new, but there is some dust particles inside. Please could you tell me what liquid did you use to clean the optical elements? For about 30 years I still keep half a bottle of Kodak Lens Cleaner, which is based on a mixture of water and ammonium carbonate. But I don't know if there is a more recent and much better lens cleaner. Thanks in advance!

レンズクリーニング液は「富士フィルムのレンズクリーニング・リキッド」と「IPA（アルコール）」を使用しています。無水エタノールも良いです。

If you are so kind, please one last question. What helicoid grease would you recommend for this lens? Thank you.

ダブルヘリコイドなので「#10」の柔らかめのヘリコイドグリスを使ってます。
50mm f1.4 等は「#30」を使ってます。
