Is Leica's Brand New Lens Actually Made by Sigma?
When Leica announced its brand new Vario-Elmarit-SL 24-70mm f/2.8 ASPH last week, it was interesting to note how similar it is to the 24-70mm f/2.8 DG DN Art released by Sigma last year. Has Sigma built this lens in Japan so that Leica can stick a red dot on it?
