Irix Announces 15mm f/2.4 Lenses for Canon EF

These lenses are intriguing. Would like more information on the construction of both lenses. The specs on the Irix website say that both lenses are waterproof....but there is no discussion of the materials of the lightweight lens. Also we would all like to see some reviews on IQ etc. This is really interesting.

It's a new Swiss brand.

Korean made swiss brand.

Irix Swiss Design Irix Swiss Design stands for minimalism in style while maintaining maximum functionality. It is a perfect mixture of European design combined with Korean precision. The same look and feel of all products in the Irix family. The same consistency, product packaging and complementary elements, all perfectly shaped and fitting one another.

Samyang has been trying hard to hit higher end markets recently, and the Swiss are masters at reselling things for a premium. If it is Samyang, I have to wonder if this wasn't their idea in the first place.

Everything depends on coma. Right now I use 14 2.8 L II. It has coma but not huge. If this lens has no coma (and at the same time is 1/2 faster) maybe it's a good choice. But I bet it will have...

Very interesting indeed. But I got excited last time when the new Sigma 20mm came out.only to find out about the Coma.
Also , if the price point is 800usd. makes me think it wont be good for astro. since it will probably have coma.
I really hope this will be a good one!
I really love my Tamron 15-30.It is much better than my old canon 16-35II. The only problem is the huge size and weight. plus no filters.
I was holding out and hoping that the new Canon 16-35 III would be out soon. this could make things interesting.
might be looking very nice on the front end of a 5D mk IV or 6D II :)

There are several filter kits available for the Tamron. I'm very happy with mine too. :D

My BS detector went into overdrive at "special neutrino coating"....

Yup mine too. Mind you, since billions of neutrinos pass through us every second, it's probably fair to say even my socks are coated in the stuff. ::)

Then again, they probably go round the back of CERN, do the "secret knock" on the door then ask for Big Dave and get handed a bucket of special sticky neutrinos to paste onto their lenses. Could happen.....

damn... this lense looks awesome!! "rear gelatin filter slot" :O... why there isn't a Canon lense with it (e.g. the 11-24?!)

Yeah, the price would be interesting..but if its stellar and under Canons average wide angle price or little bit higher I think that would be ok.

€dit: okay the two wide angle lenses of Canon (11-24 & 14 2.8) have rear filter mounts.

As do the 15mm f/2.8 fisheye, 8-15mm f/4 fisheye, 16-35mm f/2.8, and 17-40mm f/4.

I have just returned from the Photography Show. Final price is not decided, but estimated as 680 Euros (I home that I remembered it correctly).

Also they had 11mm f/4 behind a glass, but soon to be announced. - See the CR facebook page - there is a photo of the 11mm.

There is also a Venus Optics Laowa 12mm f/2.8 in the pipeline ... interesting how there suddenly is a flurry of interest in somewhat affordable SWA primes.

As well as the 17-40/4.0 L.

Looks sexy, but MTF doesn't look that impressive.

Their MTF graph is different to what is normally shown. I'm not sure how to read/use it.

You have to read the coordinates: curve colors stand for distance from lens axis in image plane.
Than you have to look the MTF value depending on the desired Lines/mm value. Canon uses 10 or 30 Lines/mm.

As a physicist and physics/mathematics teacher I have some understanding about reading graphs but just for me it is easier to type the data into openoffice and make a simple plot - see attached image. (y-Axis: MTF value, x-axis: distance from center, values are approximate values read from irix' graph)

edit: values taken from the following graph of the irix web page: http://irixlens.com/dist/img/mtf.jpg

I am sure I would not pay 680 Euros just because it has cool styling but that's just me. :P

For me it has a bit more that cool styling. As a lens that I'd use primarily for astro/night sky pictures, it has two very useful features:
- focus lock ring (focus once, lock it in place, no more "oops I bumped it I have to do it again")
- fluorescent markings on the lens (that one might be more gimmicky, but could also be genuinely useful)

So I'm intrigued ... and my Samyang 14mm is starting to feel insecure ...

By the way, where does the price estimate of 680 euros come from? I couldn't find it anywhere other than here, did someone hear it directly from Irix?

Blurb is talking about being designed for he new generation of 50mpx+ sensors, I'm not expecting this to be a bad lens, something balanced between Samyang value and Zeiss quality, with pricing inbetween - I'd expect to see a series of primes over the next few years at standard focal lengths - given Canons lacklustre drive to fill the 50mm & 85mm markets with new fast primes, I'd hope they would offer up a good target for Irix next, followed up with 24, 35 and 135 maybe... Bingo, new boy in town, move over Zeiss !

This look like a well built lens and I like the idea of the infinity click if it works as expected.
If the IQ is the same as the Samyang 14, has less coma (some copies are very bad), better QC and less distortion this would be a must have if it was around £500.
The Samyang is a great lens but only if you get a copy that hasn't got misaligned elements or shifted focus ring.
