Well, this is unique in the market. A 70-200mm with mounts that change out. The only Cine Style zoom that will cover Canon’s new $15,000 4K DSLR, or a Nikon D800, or a 5Dmklll. On an Epic, it’s relative field of zoom would be closer to around 100-300mm. It’s T2.9, but no word on whether it will resolve 4K. They also announced some fast primes.
