Rated 5 out of 5

Nikon should have come up with this lens. Irix bested the best

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.

great ultra wide angle

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.

Great wide angle lens for those hard to get interior shots

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.

what's the reasonable price for ultra wide lens

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

Love for long exposure and astrophotography!

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.

Irix 11mm Blackstone

a minimal distortion wide angle lens

The Irix 11mm lens is an extremely wide Full Frame rectilinear lens with a 126° angle of view. 4 high refractive lenses, 2 ED lenses and 3 aspherical lenses guarantee minimal distortion, as low as 3.13%, making our 11mm f/4.0 lens absolutely unique in its class.

a lightweight option with no optical compromises

a lightweight option with no optical compromises

The Irix 11mm Firefly lens offers the same optical performance and high quality mechanism as our Blackstone, but its ultra lightweight construction makes it the perfect choice for hikers, travellers, or anyone who simply likes to pack light. The ergonomic, anti-slip, rubber coated focus ring makes for a practical, user-friendly lens. This lightweight option is ideal for on the go photography, without any compromise on optical quality.

The Irix 11mm f/4.0 Blackstone is compatible with full frame and APS-C sensors. As a fixed focal lens, it has a higher technical quality than wide angle zoom lenses and it will oblige you to look for the best frame for each photograph. You will be in absolute control of your own work. You will have an angle of view of 126° to work with.
