Optics manufacturer Irix has announced the release of a stills version of its 21mm prime lens, the 21mm F1.4. As with the other lenses in Irix’s cine and stills lineups, this lens remains optically unchanged from its cine counterpart, with the only difference being the external design and more traditional focus ring.
Illustration of the optical construction of the 21mm F1.4 lens.
This full-frame lens is constructed of 15 elements in 11 groups, including four ultra-low dispersion elements, four high-refractive index elements and two aspherical elements. Irix says the optical construction limits distortion to under 2%, making it an ideal candidate for architectural and real estate photography.
The 21mm F1.4 lens features electronic aperture control, but is a manual focus lens with the usual rubber grip found on Irix’s other stills optics. Other features include an aperture range of F1.4 to F16, an 11-blade aperture diaphragm and a minimum focusing distance of 30cm (11.8").
The lens is weather-sealed and is chipped to provide full EXIF data transfer and focus confirmation support for compatible cameras. It also features Irix’s focus-lock ring, which helps to prevent accidental bumps on the focus ring. Below is a small sample gallery of images captured with the 21mm F1.4 lens:
The lens is available for Canon EF, Nikon F and Pentax K mounts, but is also fully compatible with mirrorless cameras via the appropriate adapters. The Irix 21mm F1.4 lens is currently available through Irix’s EU online shop for £675.75 / ~$890.
Is this Irix $890 lens better than the Rokinon 21mm f/1.4 for only $290 that works for E-mount? If yes, why? Any MTF charts to backup your claims, if you do try to answer this question? If not, please have definitive proof to backup your claim(s).
Because these standard mounts can be adapted to whatever in the mirrorless world. The lens might even reasonably work on the small medium format bodies like Fuji GFX. You can't expect manufacturers of niche lenses to cater for all kinds of demands @ bargain prices. Guess the cine version is also quite a bit more expensive. Or you could simply buy that
Because of scales became meaningless in our world. Things perfectly in focus on Instagram or even on a Sony A7s whatever don't look so good on a huge print from a Sony A7rIV.
Don't tell me, it's not available for Sony. It can easily be adapted, there are even solutions to communicate exif data
Back to dof - detailed crop of a high resolution sensor are in another league to what I would reasonably do. As #nerds consider 100% Lightroom screenshots as standard, no company would risk being told off by one of the influencial halfwits of misleading dof info if the next generation of like 100mp ff sensors is out
I am wondering when most third-party lens developers will stop releasing new DSLR lenses. There have been no new first-party DSLR lenses (with the obvious exception of Pentax) since September 2018, and if we exclude long tele lenses whose optical design wouldn’t really be different whether designed for DSLR or mirrorless, not since August 2017.
Camera makes do have different incentives. They have to build up a large enough lens portfolio to make their new mirrorless systems attractive and thus put all their resources behind it. Third-party lens manufacturers don’t have that incentive, they mostly just need to look at the size of their potential market with no need to make any given mount mire attractive.
"I am wondering when most third-party lens developers will stop releasing new DSLR lenses" As long a there are enough DSLR users who are potentially interested. That is as simple as that.
Did I anywhere say or even imply that there won’t be any sales of DSLR lenses in the future? The point is just that: A) For some time already, sales of DSLR lenses have been declining while those of mirrorless lenses at worst have been level. Or said differently, the ratio between DSLR lens sales and mirrorless lens sales has gone down. B) The ratio of lens sales to installed users is higher for mirrorless than for DSLR since DSLR users have owned their camera system on average for longer and every DSLR user who has switched or is considering switching to mirrorless very likely has reduced if not stopped buying new DSLR lenses some time before making the switch.
Some people like to pretend that DSLRs will hang on for a long time. However history has shown that if a mount has been abandoned by its creator, its usage will drop relatively quickly. BTW, the last (real) DSLR lens released by the big Japanese third-party brands (which was also the last such lens with autofocus) came out two years and five months ago. The category “new DSLR lens” has become a niche, catered to by niche brands like Irix and Laowa, with some minor updates (without changes to the optical design) by semi-niche brand Samyang thrown in.
Wondering when we will see the last new dedicated DSRL optical design is far from a heretical question when all first-party makers besides Pentax as well as third-party brands like Sigma, Tamron, Tokina, Samyang and possibly Zeiss apparently have already thrown in the towel (Voigtländer did so many years ago) and others like Kamlan and 7Artisans never entered that arena.
I am a huge fan of the 20/21mm and currently having a lot of fun with the Voigtlander 21 F1.4 E-mount, also have a few Zeiss 21 F2.8 Distagon ZE and Zf.2 for my DSLR systems, as well as a Nikon 20F1.8G, especially interested in the Coma performance of this new Irix, will be a really nice Milky Way lens if it has good Coma performance, I tried their 15mm and it was pretty decent. also love that is a Manual focus lens.
Pentax is the only brand that is still actively developing a DSLR system. Its marketshare among DSLRs therefore very likely is increasing and will keep increasing.
@mermaidkiller Just because it's a shorter flange, doesn't automatically assume smaller and lighter. All the mirorless 50mm f/1.2's are bigger and heavier than Canon's 50mm f/1.2 EF.
People haven't stopped shooting the millions of cameras with those mounts; they're also first party native adaptable to the respective new mount models.
Terrible Photographer; Yeah, because the new versions are order of magnitude better optically than the old ones, so that's a false comparison. In order to make a correct comparison you have to compare lenses that actually have the same optical performance - and in that sense, while some mirrorless lenses are larger by absolute measurement, they offer better optical performance relative to the size. Also, look at Nikon's new Z 14-24 2.8 how much lighter it is than the old F-mount version. There you have a prime example of short flange distance coming into play.
@Terrible Photographer They are also in a magnitude better optical. The old RF is an 8/6 design where the new RF is a 15/9 design. Maybe you don't like the "new" big style, but that is what they all went for.
Primarily, Irix makes cine lenses designed for Positive Lock and EF mounts. They'll rehouse the optics for the most popular SLR mounts, since it isn't too much effort, but designing short-flange lens versions would be a bunch of work.
I wish there was a modern day Tamron Adaptall system.. you could buy the lenses, then whichever adapter for them is required to fit your camera. It wouldn't be too difficult to do and, judging by all the EF and Nikon F to <insert your brand here> adapters, probably not even very expensive in the long term.
Wonderful focal length, I have the Irix 15, which is very good quality optics, and even more so for the price, but for my use ends up being a very special purpose lens that doesn't get used a lot... This 21mm might be the sweet spot for a moderate UWA on FF. Nice to see them cranking out solid useful products in various mounts.
I actually consider the price very attractive,, the Voigtlander 21 F1.4 is $1100, and the Zeiss Loxia 21 is $1400, and I bought them specifically because they are true manual focus lens and it has great optic, most likely I wouldn't have bought them if they are AF lenses with Focus by wire design.
And now I am really interested in this new lens also because it's manual focus lens.
But yeah, the price of the Pentax thingie makes you think twice or thrice. I had decided to buy the first new super wide angle Pentax lens that arrived. And then it came, and I have not bought it yet. Half the price and I had already bought it, but .... I assume I will anyways.
All buzzwords; they mean nothing until you actually try the lens. Although I'm impressed with my Irix lens; I doubt they're actual neutrinos but it's not bad for a 3rd party product.
