Digital cinematography support services provider 4K London has purchased Leader LV5330 and LV5380 multi-standard video signal analyzers. The sales were made via Leader's UK reseller Thameside TV Shepperton. We are an agency supplying digital imaging technicians and equipment to filmmakers says 4K London's workflow supervisor Tristan Hey. These latest purchases join our existing inventory of LV5330 instruments which have been used very successfully since we purchased them in mid 2011. They have proved very effective for digital cinema shoots made with Panavision and Arri Alexa/Codex workflow Red Epic and Sony F-65 as well as other digital formats.
