    The newer version K35s were 50mm T1.4/1.5 not 55mm. I guess that would correspond with Canon transition from a 55 breach mount aspherical to 50mm nfd

    Come to think of it since the motion picture stock was mostly tungsten balanced and still stock daylight balanced the K35s needed to be warmer. From what I have seen the coatings on them have blue...

    From what I have seen the fast 18mm K35 is based on the 24mm with a wide angle front adapter, a'la aspheron. That explains the lack of light loss compared to the 24 and the coverage drop. The glass...

    14mm FD is really an awful lens. Mechanically very flimsy, optically soft and slow. There is really nothing appealing about it. sigma 14mm T2 is a better option to match the K35s IMO. Speed wise and...

    Easy Clint,
    That was Elons joke. Typical for him, the marketing master. Being here you should figure it out. I think the bullet proofing is also a joke since ball bearing is about the most effective...

    the speedbooster covers 16x24 (29mm diagonal)
    it should cover 14x27. Komodo sensor may be wider but it is lower (30.5mm diagonal)
    or maybe not....depends on the lens it's used with

    I also don't think there are any "newer" sigmas that are dedicated designs for minimized breathing. These newer lenses are just cosmetic and probably mechanical tweaks to improve the mechanics. The...

    There is no such a thing as "reduced breathing " in cine versions of still lenses. Breathing is an optical property- not mechanical. The only way to do that is a lot more complicated design with a...
