Irix 15mm f / 2.4 Firefly

In short

The IRIX 15 f / 2.4 Firefly is a manual ultra-wide-angle lens for Canon EOS full-frame DSLRs with automatic iris control.

IRIX 15 f / 2.4 Firefly is a very good solution with a relatively low price. The lens deserves due attention and I can safely recommend it for its intended use.

The Irix 15mm f/2.4 Firefly is available in versions for Nikon, Canon, and Pentax SLR systems. Many photographers use the Irix 15mm f/2.4 Firefly on mirrorless cameras through the appropriate adapters. June 7, 2023 Irix 15mm f/2.4 DragonFly version for mount mirrorless cameras released Sony E.

Irix 15mm f / 2.4 Firefly


The lens comes in a stylish box, in the middle of which is another metal box (similar to metal square boxes for tea). Complete with a lens comes a hood, front and back covers, soft carrying case, warranty card and instructions in different languages. In a metal box, the lens itself is firmly fixed with soft seals.

IRIX 15 f / 2.4 Firefly assembled well. The lens has metal mount mount. The focus ring is wide and rubberized, tactilely pleasing. The main body is made of plastic. The thread for the filters is also plastic.

Separately, it is worth noting the fact that the IRIX 15 f / 2.4 Firefly supports the installation of conventional light filters, which are screwed into the thread of the front light filter. The vast majority of these ultra-wide angle lenses do not have the ability to use conventional front filters. Unfortunately, the thread diameter is as much as 95 mm and it is not always easy to find such filters. The company recommends using the thinnest possible light filters; also, Irix produces a line of its own light filters, especially for this lens (models ND, UV and CPL by 95 mm).

The bayonet side is holder for gelatin filters 30 * 30 mm. The instructions have a template for cutting such a filter.

The lens is dustproof and waterproof, its body has a number of internal seals, as well as an O-shaped elastic band-mount seal.

Weight IRIX 15 f / 2.4 Firefly is about 600 grams. In the hands of the lens feels like a good thing. The lens weighs a little less than the original similar Canon EF 14 mm 1:2.8 L II USM.

Design IRIX 15 f / 2.4 Firefly your own, as well as your own design of the back and front covers.

Diaphragm consists of 9 rounded petals and form a hole in the shape of a regular hexagon.

The package comes with a small plastic lens hood labeled [irix] ILH-15A Made in Korea. The hood is installed in special grooves near the front lens of the lens (bayonet type hood), it can also be installed in the opposite direction for transportation. There are white strip marks for installation. The hood locks securely, but very tight... At first, I was sure that the hood did not snap into place at all until I applied enough force and heard the characteristic click of the hood securely in place. Also, removing the hood is not always an easy task - if you grab it in the wrong way, it cannot be removed.

The hood has special windowwhich can be closed and opened and which serves for easy access to the filter. With this window, you can easily rotate, for example, a polarizing filter and use a lens hood mounted on the lens. In the closed position, the shutter of the hood window may rattle with little shaking.

Difference between Firefly and Blackstone Versions

The lens is available in two versions: Firefly and Blackstone. We can say that Firefly is a lite version of Blackstone. The main differences:

  1. Blackstone case made of aluminum-magnesium alloy. Firefly housing made of lighter materials (most likely ABS plastic)
  2. Firefly 12% lighter (just something?) than Blackstone
  3. Blackstone uses a special 'premium' coating on the body, scratch resistant. Firefly uses the usual plastic finish.
  4. Blackstone uses metallic anodized focus ring. Firefly has a plastic, rubberized, anti-slip focus ring.
  5. Blackstone has engraved marksFirefly - simple, painted with paint
  6. Blackstone for tags uses fluorescent paint (responsive to ultraviolet light in the dark). For marks on Firefly use plain white paint
  7. Additionally Blackstone has front lens protection from bad weather conditions (additional seal near the front lens)
  8. The versions differ from the supplied wardrobe trunks. Blackstone comes with hard caseand Firefly with soft case
  9. Blackstone approximately one third more expensivethan Firefly ($ 575 vs $ 425)

The IRIX 15 f / 2.4 Firefly only has manual focus. The focus ring rotates 135 degrees. The rotation is quite tight. There is a small rubbing sound during focusing.

Focus ring has special ledge, which sometimes makes focusing easier.

Passing the 'infinity' mark, the focusing ring clicks (something like a hard stop). The focusing ring has a small infinity flight, and this click, which was called hard click, similar to Infinity Hard Stop, allows you to quickly and accurately focus on infinity.

There is a special connector on the lens, which, using small manipulations with a screwdriver allows you to calibrate the focus to infinity. In fact, this function allows you to fine-tune the correspondence of the marks on the focus ring and the actual behavior of the lens on each individual camera. I did not check this function, since the instructions indicate a certain danger of dropping a screw in the inside of the lens. Important: before using this function, be sure to read the instructions.

In addition to the focus distance scale, the depth of field scale and the tag for working in the infrared spectrum there is hyperfocal marking for aperture F / 8, F / 11 and F / 16. This is a pleasant trifle, this scale allows you to create the largest depth of field with the selected aperture. Hyperfocal Details here. True, I still have a question, why there are no tags for F / 22?

IRIX 15 f / 2.4 Firefly has another extra ring Lock / Unlock, which allows you to fix (clamp) the focus ring in a certain position. It is not recommended to rotate the focus ring when it is pressed by the locking ring. To fully lock the focus ring, you need to hold it tightly enough with the Lock / Unlock ring. After tightly clamping it, the Lock / Unlock ring can be difficult to turn the other way, as it is quite narrow. There is an arrow on the ring that indicates which direction you need to rotate in order to lock the focus ring.

Focusing internal type. During focusing, the front lens and its frame remain stationary. During focusing, only the rear lens group (on the bayonet side) moves.

Focus Acknowledgment via JVI carried out due to the sound signal and / or highlighting of the point / focus points. However, despite the presence of microprocessor contacts, the lens does not allow the use of a focusing trap, i.e. Keep the shutter button locked until the focus is accurate.

Other features:

  • Focus shift (shift-focus) is missing.
  • the 'Focus Breathing' effect (changing the viewing angle during focusing) is small.
  • Adapter compatibility unknown Canon mount adapter EF-EOS M for using optics with a bayonet mount Canon EF/Ef-s on cameras with a bayonet mount Canon EOS M
  • Unknown compatibility with Canon Mount Adapters EF-EOS R for use with mount optics Canon EF/Ef-s on cameras with a bayonet mount Canon EOS RF

Important: The Irix 15mm f / 2.4 Firefly is a third-party lens. It may happen that it will not work correctly with some Canon cameras.

Image quality

Important: on modern Canon EOS cameras, you cannot set the aperture value F / 2.4 in the menu. The maximum aperture with the Irix 15mm f / 2.4 Firefly is 1: 2.5. This does not mean that the lens F / 2.5 instead of F / 2.4, just the Canon EOS cameras in the set of standard values ​​do not have F / 2.4. Step changes exposure from 1/3 to 1/2 or 1 step does not solve the problem. The F / 2.4 aperture itself is only a third step lighter than the classic F / 2.8. It is considered simple: (2.8 * 2.8) / (2.4 * 2.4) = 1.361.

Optically given lens turned out to be very successful. It is very sharp in the center of the frame already at F / 2.4, the drawdown in sharpness to the edges of the image is negligible. Only in the corners can deterioration be noted. When aperture, the entire frame is aligned in sharpness. There is a certain curvature of the depth of field that inexperienced users can take for blur in different areas of the frame.

For such lenses, distortion is a very critical parameter. The distortion of the Irix 15mm f / 2.4 Firefly is slight and visually pleasing to the eye. For RAW converters, there is a lens profile that allows you to get rid of it almost 100%.

The lens confidently holds backlight, only in very rare cases you can get tangible glare (example) In most cases, the Irix 15mm f / 2.4 Firefly is practically insensitive to the sun in the frame.

Chromatic aberrations even in the corners of the frame are at a low or acceptable level. There is vignetting at F / 2.4, which almost completely disappears to the F / 5.6 aperture.

I found information from other users who claim that the Irix 15mm f / 2.4 Firefly can easily match the quality of a picture with a native like Canon EF 14 mm 1:2.8 L II USM..

The IRIX 15 f / 2.4 Firefly is an optically and mechanically good lens. The disadvantages are small, and the functionality is huge. The price of the IRIX 15 f / 2.4 Firefly is quite affordable and I recommend it to all amateur and professional photographers.


  1. automatic iris control and correct operation with EXIF
  2. the ability to use threaded filters
  3. the ability to use filters on the bayonet side
  4. high aperture (one third higher than F / 2.8 for many other similar lenses)
  5. quite convenient and thoughtful manual focusing with an auxiliary click for quick and accurate focusing to infinity and an additional protrusion on the focus ring
  6. confirmation of focusing (by sound and / or highlighting of focus points in JVI)
  7. optional focus lock ring
  8. the ability to calibrate the focus yourself
  9. depth of field scale, hyperfocal distance scale, label for working in the infrared spectrum
  10. dust and moisture resistance of the lens
  11. a window on one of the lens hoods for convenient work with filters
  12. the ability to use gelatin filters on the bayonet side
  13. a large number of special optical elements in the optical scheme, special enlightenment of optics
  14. nine aperture blades
  15. stylish and pleasant design of shipping boxes
  16. included hood
  17. two choices: Firefly or Blackstone
  18. swiss design
  19. good, and sometimes high optical performance, especially for a lens of this class
  20. there is a lens profile for RAR converters ACR / Lightroom
  21. nice little things, for example, on the official website you can easily download the lens in high resolution, extended MTF graphics, etc.


  1. the lens hood is installed very tight, sometimes it is very difficult to remove
  2. large diameter filters
  3. tight focus ring (is it possible only on a copy from the review?)
  4. the ability to damage the lens by the function of fixing the focus ring, the focus ring can be rotated even with the lock ring pressed tightly, which cannot be done
  5. the locking ring is narrow enough; when tightened tightly, it is difficult to turn back
  6. focus calibration can be difficult and dangerous for inexperienced users
  7. there is no way to set the focus trap (rather a Canon EOS system problem)
  8. focal length of 15 mm instead of the wider and more familiar 14 mm in similar lenses, for example Canon 14mm /2.8 L II.
  9. Incorrect display of the maximum open aperture on Canon EOS cameras. The maximum aperture can only be set to F / 2.5 (more a problem with Canon EOS cameras)
  10. no tags for f / 22
  11. vignetting at F / 2.4, angles at F / 2.4 still sag in sharpness
  12. little information on certified IRIX lens service centers
  13. lack of data about the lens in modern cameras, which makes it difficult to automatically correct some types of optical distortion (distortionvignetting etc.)

  • Lynx

    Irix entered the market quite well, right away with width.
    By the way, they are not delivered to Russia.

  • Lynx

    And the design is very nice, and after all Switzerland.

    • Sergei

      it says it’s made in Korea, doesn't it?

      • Arkady Shapoval

        Lynx speaks about design, and the design is Swiss, there is an inscription SWISS DESIGN

  • Czeslaw

    Arkady, as always, an excellent review! It was interesting to read about my lens :) By the way, there are rumors on the forums that Irix are produced at Samyang factories and there is a small percentage of defects in which the lenses are crookedly inserted, which is why part of the frame is not in sharpness (ghm ... Samyang 14mm 2.8 has such a jamb often happens)

  • B. R. P.

    Thanks for your review. Very interesting things - hyperfocal distance marking, focus calibration, Hard-clik, Lock / Unlock. And the image quality is on par.

  • Alexey

    Nice lens. Is there a version for nikon?

    • Arkady Shapoval

      Yes, it exists, it is indicated in the review. Here's a.

      • Alexey

        Thank you.

  • Serhiy Todoriuk

    Great review of a great lens! Thanks. My little note as the owner of the three firstfruits iso 50 in 5d takes one and a half two stops of DD. It’s unrealistic to pull out the light from the ravah after ISO 50, they are stuck as if from a jpeg, with ISO 100 the light is pulled to the second stop calmly. The shadows on ISO 50 are also a little darker, but the main problem is of course the stuck light, so it’s the first thing ..

    • Alexey de Paris

      this is a valuable infa, I myself have heard about this for a long time and since then I have not been chasing the opportunity to use, well, the lowest ISO straight. But is it only in the first place so? A reduced value is always an extreme. no ?

    • Arkady Shapoval

      no matter how much raw 5d with iso 50/100 I didn’t pick, I never saw the difference of two stops there, because “stop-second” is not quite a reality. According to my observations, no more than a stop

    • koba

      and why the first 5d, the second and the third do the same, everything below iso200 immediately removes the light, well, their matrices cannot pull out dd without iso200, there is even their dd on this - this is already the result of manipulations with curves during the creation of a RAW file. Irix is ​​like a Polish company, or am I wrong? But they make first-class lenses, and for the right price, such a one would have set $ 3000, since they will not deteriorate often and the company will not be able to recoup money for new sales.

  • Aries

    IRIX 15 f / 2.4 Firefly is a manual ultra-wide-angle lens for full-frame sensors. not 15mm

    • Arkady Shapoval

      Crop Nikon and Kenon are slightly different. Canon cameras based on APS-C sensor have a crop factor Kf = 1.6, while Nikon has Kf = 1.5. Canon also has APS-H cameras with a crop factor of Kf = 1.3. EFR is recalculated as always - very simply, FR * crop factor. As a result, the EGF on the Canon crop 15 * 1.6 = 24 mm, without any options.

  • zengarden

    Interesting Firefly; for landscapes very much, but for architecture - too much distortion will have to be corrected.

    • Vladimir

      I completely disagree with you. If you work correctly with the lens, distortion and perspective distortion are minimal. I have been shooting professionally at him for a year now, only positive Emotions !!!

  • Dima

    Found a very interesting comparison of this Irix Firefly 15mm with Laowa 15mm f / 2.
    Irix wins in the center and loses in the corners, and this is on all diaphragms. In general, Laowa is lighter, more even, less vignetting, less hares, so it’s better for assembling panoramas. Laowa has a smaller filter diameter and is suitable for 100mm gradient filters, unlike Irix, which needs 150mm plates. Well, dimensions with weight, too. However, Laova is only under Sonya, but Irix can be installed almost anywhere natively, or through an adapter.

    • Arkady Shapoval

      Laowa 15mm f / 2 FE Zero-D has a shorter working distance, apparently making shirik with such a segment easier.

      • Aperturer

        There is an even darker Laowa 15mm F / 4 macro - it has a large flange focal distance and is suitable for DSLRs. It would be interesting to compare with her.

    Arkady, it’s necessary to block these bots, to prevent them from publishing posts without pre-moderation.

      They are filtered, very rarely some sly spam can slip through

  • Max kotov

    Thanks for the review, I liked the lens. On A7, the colors are weird in the examples, any improvements when converting the type of resonance?

    • Czeslaw

      These are already processed photos. Unfortunately, I didn’t save the source code.

  • Nicholas

    Where can I download the originals of photos taken on the A7 III? Or how to contact the author? Fell in love with them, I want myself on the desktop all of them: D

    • Czeslaw

      You flatter me: D

        Can I contact you in social networks somehow? Interested in some of the nuances of the lens and your photos

  • Dmitriy

    Hello. Sorry if my questions seem silly, I'm just starting to photograph. Here I am looking at the photos taken on the "shiriki" and I do not understand, the photo in which the horizons are rounded, buildings and trees are tilted, is this normal? Or is it then somehow aligned using programs? It just seems to me that crooked objects in the photo are not very beautiful, or is it considered the norm for such photos?

    • Arkady Shapoval

      This is a transfer of perspective. For example, this lens is almost without distortion, because all straight lines remain straight, including the horizon, but they can have an inclination towards the center

      • Valery A.

        Hello. Dmitry, I agree with you, the falling tree houses are very good. they look unnatural, these are already “perspective distortions”, there are, of course, measures to correct them digitally, in Photoshop and some other programs. In this case, the "bonus" reduces the resolution of the picture (slightly blurred) and cropped (cut) part of it. Prevention of P.I. when shooting wide (not counting the use of special lenses) - keeping the FA in a position close to horizontal, which is still possible for a landscape, but not for architecture.

        • Dmitriy

          Arkady and Valery thanks for the answers. All clear.

        • anonym

          tilt & shift will save everyone, especially when shooting architecture

  • lech

    It seems like a modern version of the lens from the 80s. As far as I remember, then all the lenses were tightly cranked. With the advent of autofocus, they gradually turned into plastic rattles.

  • Molchanov Yuri

    Finally, an intelligent overview of this lens has appeared! On English-language sites it is written that it is impossible to understand whether it suits me personally or not (the test in the magazine, photographie and does not count, they are in German).
    Thanks to Arkady for an interesting and detailed review.

  • lech

    11mm is so a beast!

  • Alexander

    Good afternoon, the question is off topic - where to get such filters?

  • anonym

    Is the large diameter of the filters a drawback? Yes, on such FRs it’s generally a miracle that there is an opportunity to use front filters! For me personally, this has become a decisive factor. still, the wide-angle frames with the ND400, for example, are simply excellent.

  • yuricxn

    I have such, wrote from Lativia
    the review is actually exhaustive, the hood is of course a separate sadness for installation
    like 15 more than 15-30 / 2,8 G1 tamron
    expensive filters of this diameter and very rare

  • R'RёS,R ° F "RёR№

    I own such a lens.
    The lens is beautiful, Nikon d750 carcass.

    I recently bought it. Very like. While in the landscape and astro did not use.
    Unrealistically expensive filters for him. Now on Ali I found two - NiSi and Wtianya. I sit and think what to buy. The price is almost the same, but as I understood NiSi the old version, not the one presented on the site and the thickness is 5.2mm, but the second is 2.5mm, but no-name.
    There is one more nuance. Does not confirm focus in the LiveView (no green frame).

    Arkady, thanks for the review! Having bought this lens in the Blackstone version and put it through an adapter on the Sony A7S, I faced the problem of blur at infinity. It is quite a normal situation, but an attempt to calibrate it manually was unsuccessful - in the focus adjustment window on the lens barrel, everything turned out to be not quite the same as in the manufacturer's video. While the officials do not answer, I thought - is manual adjustment as such a good or bad thing? After all, it would seem that adapters are created in order to compensate for the focal length of the optical system. What else does she need?

    A wonderful lens, the sharpest super-shirik of all that I had (and I had: sigma 10-20mm f3,5; tokina 11-16mm; tamron 17-35mm f2,8-4 old; samyang 14mm - and all of them except samyang, so-so). At f4 it reaches absolute sharpness. The only negative: large mdf (25cm).

    strange. Downloaded examples to RAV, very unsharp, worse than the cheapest samyang 14mm. I don't understand what to pay 30 tr (well, or $ 400)
