Irix Firefly 15mm f/2.4-22 Ultra Wide Angle Lens with Built-in Chip for Nikon EF Digital SLR Wide Angle Lens for Nikon

I wasn't sure exactly what to expect when I ordered this lens. The package arrived, and as I was opening it, I was surprised to see a nicely made tin housing the lens. I wish my Canon L glass lenses that I have bought came packaged as nicely. I looked down at the lens and picked it up noticing it's heft. I mounted it to my camera and realized that it must have been made to some tight tolerances because of how nice a snug fit it had to the body. It works very well. The body seems tight and awesome. No slack or loose fitting parts. I went on the companies web site. the biggest difference between this lens and the one that is about $200 more by the same company (Irix) is that the more expensive one has a metal body more along the lines of the "L" glass. I would love to have one so I could do a side by side comparison, but I don't have that sort of cash to play with. I believe that the internal optics are the same in both. On a side note, if you go to the companies web site they also make a 11mm version. I haven't seen it on amazon yet. The pics that I have added of the church interior are straight out of the camera. No editing to improve them in any way. The other photo I added to show off the bokeh of the lens. If you want to order a filter or two for the front of the camera, it is 95mm. Yes, you read that right, 95mm. I picked up one on amazon for next to nothing compared to what most filters cost and it works great! Irix makes their own brand of filters, but sadly didn't see any list on Amazon. The lens takes crisp photos. I'm impressed with the quality of the glass.The BadIt's supposed to run a f-stop range of 2.4 to 22. My camera reads it as a 2.5 I can live with a 0.1 difference. That's it. So far that's the only bad thing I have to say about the lens.

This lens is amazing. It exceeds my expectations. I reviewed a number of wide angle lenses before going with this one and I'm glad I did. The picture quality is amazing. I did notice very mild vignetting when shooting with the lens wide open at F2.4, but nothing I couldn't live with and no one seemed to notice it. It clears up around F5.6. I originally got the lens to shoot large wedding parties and have everyone in focus when lined up for the group photos. This lens nailed it!!!!! I thought I'd try my hand at some landscape photography, and the photos with this lens are getting tons of positive feedback. I recommend it. The price is grate. I have the Firefly version, but if you are willing to spend about $200 more bucks, the Blackstone version is weather-sealed and a bit more sturdy. However, the quality of the photos is exactly the same with either version.

This was a used lens from Adorama. It was stated as very good and I would rate it excellent. As for the lens itself, I found that light fall was much stronger than anticipated. Lightroom fixes most of it, but it really has strong vignetting wide open and at F4. Image quality is good a is contrast. Less so than my Nikons but ok. Edges are soft at F2.4 and F4 but improve at F5.6. I found the lens construction for the Firefly version to be very good. Solid, with no play at all. Focus is heavily damped and works nicely on manual mode of a Z6.

I researched for about 10 months before committing to buy a wide angle lens...mostly because I rarely need one...but I got it! I love it. It's incredibly sharp! Only complaint is that even after talking with Irix, I could not get the lens profile added to Camera Raw...so I have to make the adjustments myself. No big deal. Honestly, there's barely any distortion with this lens anyway...very straight lines. Great lens. Ive used it for real estate photos...woah so good

Scuffed up. Dented Irix box. Aperture blades incredibly asymmetrical. Mounted it to a body and took 3 frames. Couldn't get infinity focus anywhere on the focus ring. Love the field of view and how it appears to have not much apparent distortion for such a wide lens (just looking through viewfinder...) But the complaints of poor QC seem to be true based on the messed up aperture blades and lack of infinity focus anywhere on the ring. And something is off with the way it was shipped. Thankfully Amazon said "send it back" and I'll try another copy. Will update my review pending the receipt of a second copy and testing it out ... provided it is in working condition.10/28/19 The replacement arrived from Amazon. Same dented from-the-inside box. Same scuffed up hood. Same inability to get infinity focus anywhere on the scale.

Me encato es un buen lente a un bajo precio

I was very excited to get my hands on this lens after seeing some images it produced and hearing about cool features like the infinity focus click-stop, making it great for astrophotography in the dark. Unfortunately, the focus is really, really soft. I tried it on a few different bodies, and I consistently had to stop down to f/7.1 to get anything close to sharpness, at any focus distance - which is fine under most circumstances, particularly given how much better sensors have gotten in the last few years, allowing us to bump ISO to compensate. But if you're hoping to get a quick f/2.4 for pointing at the stars or other low light settings, the reality is that while the lens can technically reach that big an aperture, f/5.6 is about the best you can do if you want to have the blobs you'll get be semi-recognizable.That said, I am impressed with the exceptionally smooth function of the lens in spite of its limitation, and the clarity of the images it does produce at smaller apertures. I've used it for everything from sunsets to group photos to fireflies, and I have yet to see any noticeable chromatic aberration under any circumstances. It produces the most vibrant, detailed images I've ever seen in a wide angle lens, and while there is a bit of distortion from the wide angle, as one must expect, it's surprisingly small and easily corrected if you've a mind to do so.Overall: You have to stop it way down to make it come alive, but if you can live with that - it's worth it.
