OM SYSTEM OLYMPUS M. Zuiko Digital ED 12mm f/2.0 Lens for Micro Four Thirds Cameras - International Version (No Warranty)

I used this on an Inspire 2 drone with the X5S camera. I love the wider field of view that this gives you over the stock 15mm that comes with it.

Save yourself some money and buy the international version. This thing works great and the manual focus is a complete pleasure to work with.

I haven't had a chance to use it seriously yes, so I can't comment on the optics except to say I haven't noticed any problems. It appears well made. The focus ring allows for manual only which seems to be intended for on-the-fly and perhaps low light shots, or manual/automatic.I bought the international version (no warranty) and saved about $100. Well worth it if you are not in a hurry. It ships in the original box, with front and rear caps. If you ordered black and find that the box illustration shows a silver unit, don't be concerned. It seems there is one box for black and silver variants.As many have commented already, the hood is sold separately for an exorbitant price.
