Just purchased an RPZ 17-50 and RPP 300.
Matt Duclos of Duclos Lenses was kind enough to put them on the projector for me. Both very sharp. Shooting with them this week.
For anyone considering a battle tested RPP 300, mine arrived in pristine condition. Red did a beautiful job, and Brian & Jason in the Red Store Hollywood, as well as my Bomb Squad Rep, Brian Scheckelhoff, were incredibly helpful in getting me the gear on time. Kudos to the Red Team.
