There is a first review of the new [shoplink 20283 ebay]Contax G to NEX adapter[/shoplink] with electronic control at DC.Watch (google translation here). The performance really depends on the lens used. And the AF accuracy isn’t top notch. The manufacturer said that this is so because of lack of support from Sony. They hope to improve the AF performance with future updates.

It will be amazingly cool if these work well with the new NEX FF.
+1
My thinking is that Sony should treat NEX as platform similar ot PlayStation. They need to support somehow developers of acessories and also app developer ecosystem should be fostered.
It is not cheap AFAIK to be PlayStation developer but people do develop games for PS3. So why not replicate this in the camera business…..
+1000. The PlayStation firmware update ideology could also be applied to cameras.
The E-mount is an “open” platform and Sony has invited third party developers. If they signed up and still didn’t get support then they have every right to complain of lack of support, but so far we already have Zeiss and Sigma lenses, and third party mount adapters that do work…
What’s still missing though (and I think what is hamstringing this brilliant little adapter) is lack of third party support for the OSPDAF. This adapter could be much faster if it had access to the phase detection data coming off the sensor on the 6/5R.
It would be cool if the SLT tech was licensed to makers of third party mount adapters, at least until on-sensor PDAF is properly sorted. Imagine using all those other AF lenses with full PDAF. I’d pay extra for that.
I had one of the new version 2 adapter and had to send it back as it wasn’t reliable with my contax g lenses and would get stuck in manual mode needing a shot at f25 and with my G45 wouldn’t work at all. With my G21 AF was good but had back focus. The zoom and G28 worked best for me while the G90 was the most unreliable. I’m waiting for them to send me a new adapter.
I’ve had this adapter for a couple of days, and I am not too impressed. Some further testing will be needed before sending it back for replacement or refund.
How much support are they entitled to? Presumably an open mount means the specifications are available for devs (so they don’t have to reverse engineer it like the a-mount). Sounds to me like they’re expecting Sony to fix their design issues…
Can I just say the Google translation had the best mix-ups of the DC.Watch article:
” Let’s keep in mind that you only operate on the lens aperture, exposure, so act violently.”
“That there are individuals that do not drive an individual to drive the F3.5-5.6 Bariozona T * 35-70mm.”
…maybe the new NEX zoom will feature the Bariozona lens design and an individual to drive it!
I had one and it was almost completely unreliable. Sent it back. Sold my Gs to fund a ZA 85mm.
While using the adapter, it would work about 1/3 of the time. Sometime it would take over the exposure mode of the camera eventually stopping working. Other times it would just stop altogether.
I read all directions carefully, tried a regimented protocol or two. It simply did not meet any expectations of usefulness.
On the other hand, it was a good looking unit and a good basic concept..
