Here is a (long) list of different lenses brand with their acronyms and abbreviation meaning. Listed below are the explanation of those letters and numbers abbreviation used by the following lenses manufacturers: Canon, Nikon, Pentax, Sigma, Tamron, Tokina, Sony, Minolta, Samyang or Rokinon and Olympus.
Novice , amateur, expert or pro, it's hard to know everything ... You are not familiar with a specific brand and you don't know what mean the lens acronyms or abbreviation from a different lens manufacturer. The lens acronyms or abbreviations are all these numbers and letters, which apparently have no sense, but are engraved or printed on the lenses and you wonder for what they stand for.
1) Quality of the lens: Each brand has it's own designation to tell that a specific lens is a high end or/and professional level lens.
From what I've read about Canon, the label "L" would be reserved for lenses containing fluorite (an artificial crystal), a glass grounded and polished aspherical and / or other special optical materials, it would be for this reason that some excellent lenses and considered as pro, do not have the famous red ring (L) despite a similar build quality...
2) Lenses with motor (used for the autofocus): Here also each manufacturer has its own way to "acronym" the motorisation system.
3) Sensor type and lenses: Full frame lenses and APS-C (cropped sensor) designed lenses, in the list below.
The first acronym is for Full Frame lenses / the second acronym is a lens for cropped sensor (called also APS-C).

We are doing everything with our phone, from a GPS assistant to photograph or record a movie in full 1080p HD, even post processing those images, and i don't even speak about playing 3D games, read some news on internet and so on...
At the end, when we compare how we use our phone the most, in percentage, I can say safely that we barely use it to call someone, and this is why i call mine a photophone.
