Greetings everyone! I can't seem to find information online on how to identify Mk. I from Mk. II Standard speed lenses. Any information would be greatly appreciated. I am in the process of purchasing a set of standard speeds:16,24, 50(superspeed), and 85 and would just like to confirm if they are Mk. II. Thanks everyone!

Mk1 are tiny and Arri standard mount with 49mm or 47mm fronts. Mk2 look like "normal" cinema lenses:

Those sure look like Mk2 to me.

Check to make the mechanics are good, I hear they can wear down with such heavy use (because they have been such popular lenses!). Fwiw I own a set of Mk1 standard speeds and they look NOTHING like that.

Great to hear. Thank you for the answer! The 16mm focus barrell is a bit loose so gotta get that checked but the set is quite cheap and includes a 50mm super speed. Apart from the incredible image quality, the size of these are the greatest selling point!

I am also still trying to distinguish these Zeiss Standard speed lenses with ARRI standard mount. A lot of them can be found with and without the red T* mark. To my understanding this just says something about improved coating, so the T*-lenses should be the more modern ones? But then again, they are still called MkI lenses?

Thanks, that is a great source of information indeed! What I am wondering right now: Is the Zeiss Planar 25mm f2.0 not considered to be a "Standard Speed"? Because I see no mentioning of it and I also did find it missing in other listings on the internet before.

Makes sense. What I am curious about: The presumably older version has this ring with red and green arrows that say T and F. Do you know what this is for? (I guess it has something to do with t- and f-stops, but I cannot really make a lot of sense of it)

Yes, an index mark for either T stops (measuring actual light transmission for accurate exposure) or f stops (the geometric aperture which determines depth of field) could be selected. 

Later lenses for professional cinematography were all just marked in T stops.
