A short while ago, I discovered a new Canon EF/EF-S Lens Adapter to Sony NEX Camera systems. It's basic function is similar to the more expensive Metabones adapter in which you can control the electronic iris of the lens natively through the Sony NEX camera body. I have confirmed that it works great on my Sony NEX-7, and here Landon has his own review and confirmation of it working great on the Sony FS700. [Thanks Landon]. As mentioned in the video review below, it's half the price and also easier to obtain than the metabones product also.

Exciting stuff, but now for a bit of even better news. Recently there's a new version of this adapter which comes with the much needed Tripod Ring adapter + AUTO FOCUS support. The auto focus is said to utilize the NEX's inherent Contrast Difference AF, and focusing speed is between Sony's LA-EA1 and LA-EA2 adapter. But would be a bit slower than original Canon AF. This latest version Auto Focus EF/EF-S lens to Sony NEX adapter can be found via eBay (Click Here).

This thing took about 13 days to ship to California, but it's finally here and i'm pretty impressed. This adapter allows you to mount Canon EF lenses to the Sony NEX camera and control all of the aperture settings natively. I haven't tried it yet, but it should communicate with the lens and store EXIF information into your photos as well. As you can see from the video it works pretty flawlessly, responds very quick, and build quality is very nice. To enable IS when taking photos, you would hold the shutter half way down - or that's what I had to do to get it going. During Video Mode, the Image Stabilization is on as soon as you start recording.

I didn't have much time to test everything as i'm getting ready to fly out for PhotoPlus, but I did try to 'wig out' the adapter. When removing the lens while the camera was still powered on, the aperture controls didn't come back. The adapter does not like hot lens swaps. Simply powering the camera down doesn't always help, but removing the entire adapter from the camera body and then starting over always works. There is another Metabones adapter out there that can adapt EF lenses to NEX cameras, but it's about twice the price. I have not had the chance to test this on an FS100 or Sony FS700, but i'm hopeful it should work seamlessly. If you're shooting on the Sony NEX system, you might want to give this guy a try.

For those shooting on the Sony FS100, FS700, or NEX cameras who wish to control the iris of Canon EF lenses you would need something like the Metabones electronic adapter. In the last few weeks, a few other companies have developed a similar adapter that allows you to control the iris of a Canon EF lens directly from the Sony body, and states that it also supports Image Stabilization. One new adapter quotes the following:

" I hope this does not sound too silly: We developed this 100% on our own. We took a different route, and achieved the same result, if not better 🙂 "

That's a bold statement, and i'm hoping to shed more light to see how well this new Canon EF to Sony NEX smart adapter works. Especially since it's currently half the price of the Metabones adapters.
