The Panasonic LA7200 is a great anamorphic adapter for starters and for those looking for extreme sci-fi flares and not much work in post.

Stretch is 1.33x, which means any camera shooting 16:9 (1080p or 2160p) will output perfect Cinemascope footage for post, without the need for cropping anything out.

The strong aspects of this lens are how wide you can go (around 28mm on full frame with no vignetting), the futuristic blue streak flares, and the quick and easy setup. It features 72mm threads at the back, so it can easily connect to any lens without the need for additional gear.

Being a fixed focus adapter - it doesn't have a focus ring - you adjust focus using your taking lens, as you would normally without the adapter. Performance isn't great at fast apertures, but sharpens up nicely around f/4.

Glass is in pristine condition, no scratches, dust or fungus. Comes with both front and rear caps as well as the original pouch and box. 
The original locking screw went missing and was replaced by a different one. It works just as good (see photos).
