Tokina Cinema has just announced a new series of lenses: the Vista-P. These lenses are based on the already available Vista Primes. Still, the Vista-P undergoes precise tuning at the factory, adjusting the placement of lens elements to create a more vintage look through the introduction of spherical distortion. If you already have Vista Primes, you can send them to their factory in Japan for a non-reversible conversion.
