I would love to read a history of the Japanese photo industry with an emphasis on R&D and manufacturing.

<p>Thanks for the info Ray!<br> Yes, UV and SL-1B are very similar, the skylight filter has a very slight warming effect. LB-B is indeed a cooling filter like the 82-series.<br> The serial of my lens starts with 121XX.</p>

<p>Does anyone know which variants exist of this lens? There seems to be at least two different filter options. <br> Mine has UV, SL-1B, LB-A, LB-B. The other one has has yellow and orange filters for B&W photography. Were these manufactured at different times or concurrently for color and B&W? Are there other differences?</p>
