I have been using NX1 for few shoots. It has super good autofocus with native lenses, but sadly there is no active lens adapters, yet, for Canon or other af lenses, but you can get pasive lense adapter for NX1, I use one for EF lenses, in this way your af lense is pasive and only way to change aperture is to cary one canon all the time with you.

Here is one clip I did with it. (I know it's really bad, but here you can see how camera performs in low light and with slow motion, also some color examples.

I personally like Canon colors better, but NX1 has it's own feel.

I recommend this camera for low budget shoots.

Thanks!
I really dig the image compered to Mid-class Canon DSLR.
Image is really good.

Yes, I did. The camera together with sharp lens is just crazy. I should have used Something more soft, like Sigma 24-70mm or some vintage lens.
