It was an intensive 3 days training. Mr. Guy Genin, the Technical Director of Cooke Optics Limited, taught us very well. At the end of 3 days, we covered the whole series of Cooke Primes including the Cooke Anamorphic prime lens. We were even taught how to calibrate the focusing and iris scale with the Cooke calibration software. We are glad to meet some technical crew from the USA and Spain. We now carry all the tools and knowledge needed to service and calibrate the Cooke prime lenses.
