1. Extremely sharp, even wide open. 2. Practically straight lines (unprecedented for this focal length) 3. Enormous depth of field (essentially unnecessary to focus at F8 and higher) 4. Very solid construction, top quality glass and moving parts. Currently using it to create image records of interior architecture.

I'm using this lens on a Pentax K-1 II, and it fully meets my hopes and expectations for a high quality UWA. The build is excellent. The materials used, focus action, everything down to the packing is top notch. What's even even better is the optical quality matches. It is center sharp wide open, and the corners quickly start to catch up as you stop it down, and for a UWA, they are pretty darn good even wide open. I really can't find anything to complain about, and at this price point, I don't think you can beat it.

This lens does exactly what the most expensive wide angle lens will do. I've been doing architectural photography now for forty years and only use the best equipment. This lens fits right in with my equipment list.

you can't find another ultra wide lens with such price, but not the all story, this lens have solid build, not so heavy, very easy take focus in the night and the sharpen is so good for high resolution camera. I use this lens for night and day landscape with 150mm filters system

I already own the 15mm Firefly and couldn't wait to add the 11mm Firefly to my kit. I loved it so far for long exposure and astrophotography. I use it on my 80D, so it's focal lengthis a bit more that the 11mm, but it still works great for what I use it for.
