Are all of Panny's micro four thirds lenses optimised for video?

Are any of Oly's?

What does it mean to be optimised for video: silent AF, non-jerky AF with less hunting or both?

What I have read "optimized for Video" means that the auto focus is:

Internal (no front lens movement)
Fast
Accurate (less hunting)
Silent

Also the zoomring should be smooth and silent.

For Panasonic this is the 14-140 mm

For Olympus the 14-150 mm and the 40-150 mm

Also the diaphragm blades are mostly 7 and rounded (circulair) to ensure a nice out of focus effect.

Also the long zoom range of the lenses are ideal for Video.

How about the Panasonic 20/1.7 and 14/2.5. How do those focus?

Hi Rider,

I have read in a few forums that first off all the 20mm is a great lens, but that the focus meganism makes some noice which can be picked up by the camera micro phone.

https://www.mu-43.com/f38/panasonic-20mm-1-7-noise-other-questions-1485/

On the DP review site it reads: "The focus motor is very quiet, and unlikely to intrude on any occasion. The 20mm F1.7 is also capable of continuous autofocus in movie mode." and "It's not as fast as the Panasonic 14-45mm or 14-140mm zooms".

So mixed messages here.

I have not found any info about the new 14mm 2.5.

The 20mm is one of the noisiest lenses. A loud buzz is present.
