I know this lens has become very popular, and being sold out again many people aren't able to get their hands on a copy. I was lucky enough to pick up the last copy at my local pro photo supply store. Let me know if there are any specific tests/samples you'd like me to create in another video.
Sorry about the crappy sound. I recorded from a wireless lav to the Zoom H4n. No referencing, I just kind of plugged in and went for it. Signal peaked a bit.
