Almost immediately after taking delivery the first of April 2009, my Sony PMW-EX3 could not do a slow zoom with the stock 14x Fuji lens. When using the zoom control on the lens, it would either hesitate to start, or start too fast, or start to zoom slow then hesitate, making it impossible to perform a slow zoom. On June 15, 2009 the camera was at Sony in New Jersey.
On the 25th Sony informed me that speeds below 10 on the EX3 were not guaranteed, speeds above 10 should be smooth. The camera is being returned to me with no repairs made, they did update the firmware, I was informed.
My first question of many, when you’re using the camera, and using the rocker zoom control, how do you go directly to zoom speed 10? Every zoom begins at zero and needs to be smooth throughout. I have used many many Broadcast quality cameras since 1972, producing videos full time. Even when the manufacturers referred to video gear as industrial quality, those lenses could do a slow zoom, When we had a similar problems with Canon lenses over the years those lenses were returned to Canon and repaired under warranty, sometimes out of warranty for a fee, but always in very timely manner, no discussion. The EX3 has a Fujinon lens.
