What is the F stop on tele end?
 
What is the F stop on tele end, does it stays the same 1.8 or goes up?

Yes it does. Just got mine. Serial # 68!

It's a 1.9 fstop

First impression. DOF is amazing. I may have no need for my letus35!

Sounds great, I'd love to watch some footage shot on tele end.
What is the minimum focusing distance on tele?

I remember one of the early reviewers (Simon I guess) stating that the aperture actually DOES ramp.

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.
