The word on the sets here in NY is that to counter the popular Zeiss Ultra Primes and Cooke S4's, Panavision is developing a new set of Primo primes. I haven't seen a set of Zeiss superspeeds on a job in a very long time (at least here in NY). You won't be having a problem with them at all unless they are not taken care of. The Mark III series of Superspeeds are the best. The hottest lens of the moment is the Angenieux 24mm-290mm Zoom. Everyone loves the look it gives. Many say it looks better than primo 11-1. The only thing is the weight! But then again this a 35mm format lens. Good luck.
