Alexander Ibrahim December 4th, 2007, 06:27 PM We are past specs now. The early reviewers were handling pre-production units. Lots of people have handled the production units- including me. The aperture does not ramp on the two production units I have worked with. It holds a constant f1.9 throughout the zoom range. Exposure as experienced visually on a monitor does not waver, flutter or other wise change- unless of course you operate the appropriate controls. |
