Along with the new Canon C100 announced yesterday, Canon previewed a pair of new cinema prime lenses – the 14mm T3.1 and 135mm T2.2 EF. These new prime lenses will work on both 35mm full frame and Super 35mm crop cameras (e.g., both the 5D Mark III and the Canon C300).
The Canon 14mm T3.1 and 135mm T2.2 EF cinema primes are expected to be available in the first half of 2013. No word yet on pricing; however, current Canon cine primes are in the $5k range (see, e.g., CN-E 24mm T1.5, CN-E 50mm T1.3 and CN-E 85mm T1.3), so that range is probably a good estimation.
