Irix11mm f/4.0 Blackstone Lens - Wide Angle Rectilinear Lens w/Built-in AE Chip for Canon

UPDATE (10/22/2019): I have had the pleasure of owning this lens for over 2 years now & want to update my review. Overall the image & lens quality are fantastic, pro quality, but unfortunately I ran into one major issue around the 1 1/4 year mark. Even after relatively light use the ring surrounding the front lens element randomly fell off one day when the lens was removed from my camera bag. The ring can be stuck back into place but still pops off periodically.While this doesn't appear to affect the lens quality or weather seal I expected the blackstone model to be durable enough to avoid issues like this. I am hoping Irix will fix the issue at no charge & will update when I hear back.-----------------------------------------------------------------------------------------------------------------------------------------For me this lens surpasses all others as the ultimate choice for dedicated ultra-wide landscape photography and has been a dream come true for me! I've only ever owned nikon lenses before because in the past very few third party lenses could truly compete, however this new Irix lens definately meets the high image and build quality demands of professionals while removing feature that are generally not as important for landscape photography including autofocus and zoom ability.Its truly impressive how this lens manages to pack such quality into such a small price tag, the build quality is so solid that I fell like I'm carrying a lens that should cost $1000s. Appears better than most other pro lenses. The Iris even includes a couple very useful unique features like a gel filter insert on the rear of the lens (cheaper filters) and focus ring lock. The Irix's focus ring has a slightly higher resistance to movement when focusing compared with other lenses but provides the extra benefit of ensuring the ring doesn't move if accidentally bumped accidentally.I owned the Nikon 14-24 mm for over 5 years before the Irix which is a fantastic lens and the Irix's sharpness and overall image quality appear to be quite incredible for such a wide lens, they even appear to be slightly better than the nikon at 14 mm. The Irix is sharp from corner to corner even wide open and is near perfect between f/5.6-8.Even if nikon comes out with a suitable replacement someday I will probably just keep this lens as soon and autofocus are not features I use often for serious landscape photography. I have attached an image of the lens mounted to my nikon d750 as well as Three sample images: The 2x B&W images, aperture set to f/8, are part of my actual artwork portfolio while the color image of the pepper crop was taken during a work related excursion at f/4

I am very pleased with this lens. Beautifully made and gives a great wide-angle view.I must say however, that I was less than pleased with the Amazon packaging. The Irix box (which contains an Irix tin, inside which is the Irix lens case with the lens itself inside) was just tossed in to a MUCH larger Amazon box with just some of the 'airplus' air cushions and not very many of them: because of the loose packaging it meant that the Irix box with the lens inside could easily bang around. As a consequence, both the Amazon box and the inner Irix box were knocked about and the Irix tin inside the Irix cardboard box was dented. Despite this the lens seems fine since the lens itself, as mentioned, was inside yet another lens-case packaging inside the above-mentioned (dented) tin - and just as well! For a $900 AUD item I think it is reasonable to expect more secure packaging.

A lot going for this Lens. 11mm would be a start. Any Landscape photographer would love to have an Ultra-Wide Angle Lens in their arsenal. But for the longest time the choices have been discouraging, it was simply out of reach for a mere mortal. Now it's finally affordable. Second, Build-Quality is superb. No complaints there. Third, you can insert a gel filter at the base of the lens. Fourth, its size. It's good for such a super wide angle lens. Fifth, it's rectilinear with minimal distortion. Lightroom easily corrected it (yes, it means that LR has its profile already). I have only taken this Lens for a spin just once and I am attaching some photos I took with it. I gave the IQ only 4 stars but it should be around 4.5. Is it sharp? You bet. But really for me it's the overall rendition it gives. And oh, the Infinity click is such a welcome feature. When it got dark, I just waited for that click and I was all set. Brilliant! I can't wait to take this lens to some epic locations.

Maybe that can be corrected with lens lcp files? But 'out of the box' objects a getting wider as they are off center. That causes confusion looking at pictures of an ongoing kitchen remodeling project. The '2x4's look like at least '2x12' close to the edge.The rectilinear lines are great though. Everything is straight.

Very well constructed and quality product.

I was not expecting such great image quality from a lens this low priced. It works perfect with all my Canon cameras(5D MK4, 5DsR, 6D). Even though it is manual focus if you stop the lens down to F8 or 11 everything is sharp. Very little falloff or vignetting. Very happy. I hope you come ut with a wider lens as good as this one.

Sharp corner to corner wide open if you get a good copy. I got a good copy.

This is a fantastic lens, there a little deformation at the edges but I really like this lens!

Brilliant lens. I have had the Blackstone 15mm for 4 years. Now have the Blackstone 11mm a winning combination. Built quality is excellent. Would highly recommend for anyone on full frame cameras

Arrivato a casa appena scartato si è visto l’ammaccatura sulla custodia in alluminio.Nella confezione mancava certificato di garanzia istruzioni( avendo acquistato altri obiettivi direttamente da irix era presente imballo e custodia incelofanati e tutte le garanzie) la lente si presentava bene a vedere, ma in uso non è nitida anche al centro, uso spesso lenti manuali quindi un po pratico sono. Non c’è un punto di messa a fuoco giusta.Ho fatto il reso da 10 giorni ma ancora da amazon non ho ricevuto risposta.Premetto che no ho mai avuto problemi con amazon, e la prima volta, e comunque si vede che la lente era gia stata usata e probabilmente resa.

L'ottica è unica, su reflex, comparabile solo al Voigtlander 10mm f5.6.Grandangolo rettilineare, nitido da 5.6 7.1 fin quasi ai bordi, provato su Nikon D850.Ottimo case fornito insieme all'obbiettivo, rigido e protettivo.Portafiltri posteriore a gelatina, da 30mm.Purtroppo è arrivato, nonostante fosse "Usato come nuovo", da Amazon Warehouse con dei vistosi graffi ad andamento circolare sull'elemento frontale, dovuti probabilmente a pulizia errata e non dichiarati, ad un costo dell'obbiettivo nemmeno "da occasione".Obbiettivo 5*Servizio Amazon Warehouse 0*Peccato, la lente è pazzesca!
