    An interview with Gerold Dobler, leader of the SF design team

    would be interesting to know if the new light-gray color (of the SF rubber armor) have something to do with the new lens materials. More heat sensitive? Canon telephoto lenses are said to be white because the fluorite elements are sensitive to heat. (Nikons new fluorite lenses are black though…)

    An interview with Gerold Dobler, leader of the SF design team

    Interesting that Nikon finally decided to use Fluorite in camera lenses. It seems to save a lot of weight in long telephoto lenses. Canons latest lenses are so much lighter than nikons corresponding ED-versions. Though the prices have become ridiculous on the new versions… seems to be a lot of...

    An interview with Gerold Dobler, leader of the SF design team

    If it's "made of CaF2" do you mean it's pure fluorite? I'm not a glass expert but I guess "Ultra-FL" could mean a higher CaFl2 content than ordinary FL-glass, but maybe not 100%? Pure fluorite crystal is said to be more sensitive to heat, so maybe the light gray rubber armoring of the SF is an...

    An interview with Gerold Dobler, leader of the SF design team

    just noted that it's different then FL and HT, then whats the difference? higher content of Calcium Fluorite? Fluorite crystal is very difficult to work with as well, and expensive… would be nice with some more info on the Ultra-FL glass, Dobler says: "The doublet is made from glass...

    An interview with Gerold Dobler, leader of the SF design team

    good job! very interesting! does this mean that Zeiss SF have pure FLUORITE crystal in the objective lens? (like the Kowa 883) These different glass types confuses me a bit… but in camera lenses, pure fluorite makes the lenses lighter compared to using, ordinary ED/HD glass. I guess it means...
