C Mount lens adapted for use on Sony NEX camera

I am pleasantly shocked that the Fujian 35mm C mount lens does not vignette on the Sony NEX series camera even tho it has an APS-C sized sensor which is many times the size of the 2/3" sensor this lens was designed for. A happy discovery to say the least. The Fujian 35mm F1.7 lens was under $30 and the adapter another $7 or so. Definitely a bargain for a fast prime lens that gives a nice look to footage.
