Author Topic: Motorized Lens Question Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 01-31-2018 02:26 PM                     I did notice that on SOME 4K lenses - Steve, if memory serves the Minolta of the bunch was vastly faster than all the others. Indeed what usually takes 4-5 seconds with a 2K Barco lens/projector, can take up to 45 seconds (focus - shift and zoom will take the usual time) with a B+4K lens. Nothing you can do besides let Barco know that you are not impressed.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

They all have internal focus mechanisms (All InVision). Their claim to fame is that they have a larger inlet pupil for greater lens shift. As I said before, as far as image resolving power...thus far, not impressed.  |  IP: Logged
