    Found this in Lightroom 5.5 under the lens profiles –

    Okay, fess up – who has it?

    Ha! Well well, is this prophetic? I had to check LR5.5 myself and indeed it's listed. This may get interesting.

    I've been using a 100mm f/4 Pentax and like this angle of view. But I expect an f/2 lens would be just a bit larger…

    Interesting find! I would have thought there'd be a CS version too, especially at this (portrait) focal length.

    Photokina only 2 months away 🙂

    Hi Doug – it takes some digging, but if we go back to the Leica S2 introduction when Leica was first talking about the lens line-up, the 100/2 was pictured. The 100/2 appeared to be sized larger than the 70S, but definitely shorter than the 120S. The lens barrel shapes shown in this old picture have changed, so the 100mm shown here may not be indicative of what it would look like today. The 100mm is at the far left:

    If somebody is a good data sleuth, maybe they can decrypt the modify date string. This code snippet is from the Lens Profile list in CameraRaw – it is kind of like an XML file. I thought the date string might be UTC, but that returns a date for the year 2080. Other lenses have similar date strings, so there is nothing obviously unique about the 100/2 Summicron's. It would be interesting to know when the profile was last modified. If it was 2008, then we could assume it's old stuff. If it's 2013 or 2014, then that could mean somebody updated it recently.

    The Mac OS X path for that file is: User Library / Application Support / Adobe / CameraRaw / Lens Profiles / 1.0 / psyche.dat

    The file is just a table of contents.

    This is a great addition to the line up,hopefully it has fast focusing,at least as fast as the 70 and 180,there would certainly be a CS version i the works..

    Only glass missing now is a wide TS and something longer than 180..

    My laptop lightroom version was 5.4. No 100mm Summicron listed.
    I've just updated to 5.5 and the 100mm is now listed.
    This is definitively new 😎

    Cool – I was wondering if it was listed 5.4 and I just hadn't noticed.

    I decided to pull out all the Leica S lens entries to see if there was a pattern to the date string. The date string appears to be a serial number and lenses are added/updated in batches. Each lens does NOT have its own unique date stamp. Leica R and M lenses shared the same ModifyDate, so it seems Adobe assigns this modify date – probably when the do Camera Raw updates. Other makers equipment share the same data stamps (Canon, Sigma, etc). The 100/2 was the newest addition (of the Leica date batches) with the 45/2.8 being in the same batch. The following is a cleaned up summary:

    Did some more digging in System Library and found the actual Adobe Lens Profiles for Camera Raw and there is a 100/2 .lcp file from June 18, 2014 with a complete list of lens correction parameters. So it's unlikely the 100/2 entry above is just a placeholder. Here's the Adobe lens correction file name for the 100/2 (Mac OS X) –

    Leica Camera AG (Leica SUMMICRON-S 100 mm f2 mm ASPH.) – RAW.lcp

    This all points to the lens existing and developed far enough that Leica wanted to play with the lens in Lightroom. There is no field that says “commercial release date” and “MSRP” 🙂

    It was interesting looking at the lens correction file in a text editor – it has 12 sets of data – each set is for a different focus distance. The focus distance range from .7 to 100000003318135351409612647563264. I assume that's meters. And evidently Leica has defined infinity for us 🙂 LOL
