This is the patent of the optical formula of the Leica Elmarit-TL 18mm f/2.8 Asph, just compare example 2 and 3 from the patent (which are 18mm f/2.8 lenses, only example 1 is an 18mm f/4) with the Elmarit-TL。

Thanks for the important information!

The L-mount alliance seems to be the support team for Leica by Panasonic and Sigma。
