Estimated price should be around 300 US-$

It will even make a sense to buy a Nex again because of this adapter
Let see when it will be available and what lenses will work with it.

[Rolf]

As far as I know all lenses without 21mm and 16mm (21mm you must remove the lens protection)

I love Contax G lenses, I will have to buy them again

And finally the updated version of the AF adapter is available for preorder again:

I have ordered one and it should arrive in 1-2 months.
Btw this new texture looks a little bit flashy - it's good that it is not visible when lens is mounted

Looking forward to your results. In the video the AF looks painfully slow with the adapter, a couple of seconds from button press to the acquisition. That does not look very useful to me, but of course the video is not a substitute for personal experience.

Are they going to make one without AF? That's the last thing I would want, AF!

Thanks Calvin - i have payed it already,but how can you get it so fast - you have some special relations with the manufacturer?

Hey Ian,
There are lots of adapters without AF - that's why this is special. The contax G lenses were never a manual foculs lenses and they are not very convenient to focus with the existing adapters.
That one on the other hand has also assisted MF with a small wheel and that will bring lot more useability to those nice lenses on Nex.

Cheers Stefan, that makes sense, I was a bit confused about it.

[calvin83]

It seems they are on eBay since 10 Junly. $295 with free shipping.

I have finally received it - the second version with the shiny markings

Very good adapter - small light and precise.
Easy to fit the lenses on it, and much easier to focus than any other adapters i had including Kipon and Metabones.
The assisted manual focus is awesome and very precise.

It even focuses automatically - not precise every time but generally OK for me.

Now i need to raise money for the last prime i still miss: the 45mm Planar

congrats! is this only for sony or is it available for other mounts?

Only for Sony unfortunately - I would love to have it for m4/3.

After playing with the adapter for a while seems that the AF on it is not really reliable.
The longer the lens the more incorrect is the auto focus. My Nex 5n seems to get the focus confirmed but the target is blurred.
This is most pronounced with the 90mm Sonnar - it goes off a lot regardless of the aperture set 2.8 or 5.6.
I have tried to adjust the AF (there are special aperture settings to adjust AF accuracy on the adapter) but still i can't do it - it gets close but not enough.

So 21, 28 and 35mm are acceptable but with the 90mm if you focus manually it's much better than AF.

I was close to try this out...

[std]

Don't get me wrong - it's an excellent adapter.
I think the reason is in the Nex focusing algorithm and not in the adapter itself, and the other lenses except the 90mm sonnar are focusing quite precise. Maybe the focusing zone is too big - couldn't find any option to make it smaller.
Also i can't figure out how to make the AF assist light to turn on 5n.

[calvin83]

Some user reported the G90 does not hit the focus in their Contax camera especially the G1. If you cannot find it focus properly with the AF adjustment(F29-51 and F64-90) and center AF, then you have to live with it.

Hi Calvin,
do you know if the fine focus adjustments are specific for the lens attached currently or it is applied for all lenses?
In exif i see the focal length so the adapter can recognize which lens is mounted.

Also in the instructions it s mentioned that you can disable the AEL lock in order to have metering adjusting if you close aperture while half pressing the shutter button but i can't find such option in 5n do you know if there is such?

PS: And a bit of warning - before mounting the Contax G lenses to adapter first be sure to check that the aperture index is pointing not to f22 but to the right end outside of the f scale. Otherwise you can damage the AF contacts in the adapter - i almost got one of the pins bent. If it doesn't want to mount don't force it - try to rotate the aperture ring till the end counterclockwise and then try again.

This is one way to ensure proper exposure, Even the lens is set to F8 before you focus, you may still able to get a decent AF accuracy on bright objects as the NEX use contrast detection AF.
