T2.9–3.0 · PL mount · 2019
Kestrel Zoom
Two zooms that cover the range the primes leave open. Parfocal across the whole throw, tracked and shimmed in house every six months.
Matching
The set is kept together and shimmed to the same back focus. Splitting it is possible for short jobs, but the colour will not match another set exactly and we would rather tell you that first.
Checks
Every lens goes on the projector between jobs. Collimation, back focus and iris are logged, and the log goes out in the case with the glass.
