Is that silent enough for video w/ sound & on-camera mic?

Okay, without outofocus it is silent?
How about using servo zoom?
Or none of these lenses have that?

None of the still lenses have servo zooms. Only the video optimized lenses like the Panasonic 14-140 will autofocus silently. I believe some of the olympus micro 4/3 lenses also have silent autofocus but not the lenses we're talking about here (which are normal 4/3 lenses.)

How easy it is to make slow fluent zoom without servo?
Any experiences?
Old cine zooms used to have accessories for these.
Does cogwheels (or what they are called?) for 4/3 lenses exist for remote/assisted focus/zoom?

S - af101 not working with Olympus Zuiko 35-100 f2 lens
SOS
Help anyone? I have just taken delivery of an AF101 ( = European model). I bought two Olympus Zuiko Four-thirds zooms to go with it:
35-100 f2, and 14-35 f2. The 14-35 works fine, but the 35-100 produces a black screen (even though when I look through the glass the aperture is wide open) and the lens is not communicating with the camera like the 14-35 does.
I am using the recomended micro 4:3 to 4:3 adaptor, the Panasonic DMW-MA1.
The 14-35 is listed on the "lenses that work with this camera" page of the af101's instruction manual... but the 35-100 is not!
Have I bought a duff lens, or is the 35-100 simply not compatible with the af101? I'd love to hear from anyone who uses the 35-100 with the af100...
Thanks!

Psst! Take off the lens cap!
Sorry, too easy. I hope someone chimes in with a real answer. I don't understand how there can be a black screen when light is hitting the sensor, even through what might be an electronically incompatible lens.John Hoare

Yup! Tried that...:laugh:

Agreed... but the puzzling thing is that both lenses have auto-iris (neither has an iris ring on the barrel)... but one works and the other doesn't.

apparently there is a "LENS CHECK" option in the OTHER FUNCTIONS menu that has caused some people to see black. give that a shot?

Also, for the sake of argument, tape up the contacts, which should keep the lens open (though if it closes up by default, it should be easy to see the iris blades).
This looks really drool-worthy. Maybe. Someday. http://gizmodo.com/5718347/nikon-patent-could-lead-to-dslr-moviemaking-dream-lens
About to invest in the af100 and gh2 so wanted some input on what folks think would be a better longterm lens investment: Olympus f2.0 lenses, no IS, limited autofocus, allows iris control, only useable on 4/3 and m4/3, more expensive; canon mount with birger adapter will allow af and IS with most lenses, birger allows 3rd party brands like tokina 11-16mm, slower glass at f2.8, can be used on other platforms beyond 4/3's; nikon no adapter available or in the works that I know of to give the same capability that the birger will give to canon lenses, I have voightlander manual adapter which with new lenses offers no iris control, allows third party lenses too albeit 100% manual with limited iris control.
Thank you for any input as more information comes to light.

Keep in mind the resale value on those Zuiko lenses are really good. They are also very hard to come by in the used market so it would sell easily.
That's a good point on the zuiko for resale. I shoot weddings, corporate promotional videos, green screen, general events...would love to help out on some indy type productions. So a broad mix of studio/location shoots, and run & gun type work. I have an HMC150, JVC HD100 and just sold my gh1 so wanted the af100 to further broaden my capabilities. I wish I had known about the Verse Before Dying shoot much earlier...would have loved to help out, I'm in Dallas...

For events/corporate/weddings, you're certainly going to want lenses that communicate with the AF-100, in my opinion. So I'd look at the Olympus f2 zooms, the Panasonic 20mm f1.7 and other native M4/3 and 4/3 lenses.
On "A Verse…" we used Zeiss Compact Primes and ZF lenses for most of the shots. In a narrative cinema environment, these lenses fit right into the standard on-set workflow with matte boxes, follow-focus, etc. We did use the 14-140mm and the 20mm f1.7 in isolated instances, and they performed very well, to the point that if I didn't tell you which shots they were in the film, you wouldn't be able to pick them out.

I guess the Canon Birger is still an unknown until it ships in February, plus from my research Canon doesn't have a great wide-angle equivalent to the zuiko 14-35mm. Though the Canon 70-200 IS L II (equiv 140-400mm) is supposed to be top notch. I have a budget of about $5000 for lenses alone, so want to make the wisest decision on this as I'll have to live with my choice for a while! The 20 is definitely on my list, I think with the GH2 will make an excellent stabilizer camera. Do we have any hints from any manufacturers that more video optimized lenses on on their way? Would it be worth waiting? I do have the 14-140...just not great in low light of some events I shoot.
