Contax G AF adapter available for preorder tomorrow

Go to last post
A chart now appears on the website that indicates the speed of the focusing with the adapter, which changes according to the aperture of the lens. The condition of the lens focusing mechanics also plays a role,
"Addition information (updated on 7/3/2013)
Test Camera: NEX 5, 5N, 7, 6, VG 900 (photo mode)
The focus speed depend on your lens condition, following information for reference only."

Thanks for the update. Seems adequate for still and slow moving objects.

I guess one way to use small aperture such as 16 or 22 with this adapter is focus using larger aperture then change the aperture to the smaller setting.
 
Thanks for that, John.

So disappointing. Imagine, taking 3-4 seconds to focus outdoors in good light, with all but the 90MM at f8? At f16, now you're stuck with focus hunting. Sunshine, those three lenses, and f8 or f16 are my most common shooting scenarios. Three to four second focusing AT BEST is truly a let down.

I'm starting to despair of ever having an elegant and functional NEX adapter (either manual or AF) for my Contax G lenses. Why are they all so inadequate (for one reason or another)?
 
Why messing up with this adapter when sigma can deliver 19 and 30/2.8 for 199 usd? are the AF only?

AFAIK the Contac G lenses, while v-e-r-y nice, are no longer made. Probably quite a small (in lens terms) production run?

So I wonder why they decided to target this lens mount rather than something like Nikon. Licensing issues perhaps?

Contax G system has a bit of 'cult' going on. There is a demand to use these lenses again. These are arguably the smallest full frame auto focus lenses used on Nex system.

having said that, the company behind this adapter has said there will be more adapters coming out.

on VG900, the jpeg output shows FF VG900 was in cropped mode. So G 45 + this adapter were not recognized as full frame lens. But yes, almost certain that it is possible to use CG lenses on future full frame NEX bodies with AF functions.

Therefore, this adapter is an important development. Looking at G45 photos... I want one!!!
