Summicron is Leica's trade name for lenses that open to a T2 (or f/2 for stills lenses). Also new is a 15mm lens that will be available in October. This brings the Summicron line to 11 primes in all. The Summilux family, which all open to a T1.4, also has 11 lenses, but there are some minor differences in terms of focal lengths between the two lines.
Another new product is the Leica Cine Macrolux, a purpose-built macro diopter for digital cinema applications. Leica used a simple but highly precise optical design that yields no perceivable light loss, even when stacked. The Macrolux will fit any Summicron-C or Summilux-C cine lens (or any lens with 95mm front outer diameter). For more information, and to see these products in action, watch the video above.
