When using Canon to NEX adapter the EOS lens is set at minimum aperture and there is no way to control the aperture…oh no wait, Conurus just found a new way 🙂
As you can see from the video above it really works but unfortunately that is not a real solution for now. But I guess they will soon be able to make an adapter that allows the electronic control of EOS lenses. That would be a much better solution compared to the EOS to NEX adapter with built-in aperture control made by Kipon (Click here to read that article on SAR)!

That’s great hacking! There is a company called Birger Engineering made an adapter for Panasonic AF100 which can control the aperture of Canon EF Lenses and AF too. It is a great news to the dual system user. I hope that it could be mass produced in about 1/3 price of Birger’s design.
I wish Conurus offered Contax N to Alpha conversions. Damn mechanical apertures.
Hahaha, guy did in a backyard what so many companies failed to do on their own! Awesome! (let’s just hope now that the reason those companies didn’t released their own versions of such adapter isn’t because of possible law enforcement of the big red C)
Think companies could do it, but choose not to, simply for Licencing costs/restrictions… Legally you can only do what this guys is doing with consent from Canon, which costs money (see Sigma/Tamron)… They all have to pay Canon a Licencing Fee for interfacing with their Mount/technology.
Sigma doesn’t pay – that one I know. It’s the reason why they constantly struggle with compatibility – as an example look for most recent issue with SLT compatibility.
It’s certainly not a problem in paying royalties. AFAIK none of these adapter-developers pay Canon or Nikon for the “privilege” of using their bayonet.
But just to make it clear – you can buy a specifications of a bayonet. This way there’s no money spent in reverse-engineering though it’s very expensive. Such packet comes with communications protocols described too – eg. Zeiss bought it for their ZF.2 Nikon lenses.
I was thinking the other day, instead of all these adapters with limited functionality issues, if Sony for example made specific bodies that could use Canon, Nikon or Olympus lenses. I suppose there are patent issues, but those need not be insurmountable. The convertors don’t have patent issues.
The problem you have here, is that Sony will make most of their money and business growth via selling their own lenses. When a customer buys their body they are commiting to Sony that they’ll also by lenses from them. It doesn’t make much Business or Financial Sense for Sony to openly allow other manufacturers lenses to work on their body (especially if it ends up costing Sony money to licence the use). Like I’d said above, with people like Sigma and Tamron, Sony get a cut of the lens through licencing costs, so its of no consequence to them.
However I agree it would be nice to have a Body that could do it all with any lens.
I knew he’s going to make it! Now he only has to package it into a working adapter and I’ll be typing my credit card details in no time. 🙂 Getting the AF and EXIF to work would be even cooler.
Nice to see that it’s possible. Great effort.
Please, please release this in a form of one solid piece of adapter.
We have decided to take down our “proof-of-concept” video posted on YouTube on March 12, 2011 because now that the actual product has shipped on January 18, 2012, there is no point showing the crude prototype any more. We will create and show a video of the final product on YouTube soon.
