Anyone have any views on IRIX 11mm F4.

11mm, F4, 9 blades (=18 sunbursts), 1.6lbs (vs Canon 11-24 , (DxL) 4.65 x 4.06", manual focus, $600 USD

It seems like Canon 11-24 f4, Sigma 12-24 f4 and Irix 11/f4 are the possibilities for super wide.

comparing
irix https://www.ephotozine.com/article/irix-11mm-f-4-firefly-review-30678
canon http://www.photozone.de/canon_eos_ff/940-canon1124f4?start=1
says pretty good. Sharpness better on edges than canon 11-24 but significantly lesser in the middle. okay and consistent.
CA about 5 for IREX vs 3 for canon at 11mm - both good
9 blades irex vs 9 blades canon - great
1.6 lbs irex vs 2.6lbs canon - beats canon for hiking
$600USD irex vs $2600 canon - way beats canon
filters - irex accepts rear gel filters big advantage - cp's are not usable on 11mm, ndgrads both equally challenging but I don't care for ndgrads anyway because they only work where there is no trees in foreground (always for me).

sigma 12-24 Art
$1600
f4
9 blades
2.5lbs
similar performance to canon

I think I need an 11mm. I already have TS17 and its my go to lens. I could buy the canon 11-24 or the Sigma 12-24 but I would rarely use them because:
1) Where possible, for me the ts17 shifts and this means no bowed trees
2) I rarely need 11mm end - maybe 5% of time and I can use TS17 and stitch if the object is far. Its only where its close that stitching and ts17 is not great
3) I already have the zeiss 15/2.8 for night shooting.
4) I can't carry ts17, 11-24 and 24-105 backpacking unless I work out in gym 24x7 for the next year.

The thing that prompts me is that I hiked to Floe Lake - Kootenay National Park and the mountain was just too close to get it all in next to the lake and I could not back up enough to without being in the trees. And I backpacked with my tent, sleeping bag, TS17, 24-105, tripod, food up 7 miles / 2400'. I am 57 and I need wider but I need lighter or a sherpa.

Thoughts?

Scott

Sounds familiar to me. I was about to get the Irix 11mm, too, but a used 11-24 f4 suddenly showed up at a reasonable price. As I already have a couple of manual focus lenses that see little use, I thought maybe an 11-24 would be better for me, in the long run. So far, it's OK - not impressive, but OK. I already own the Sigma 14 Art and 20 Art, that the zoom cannot match, I think. But then there is the convenience of the zoom, for everything else but nightscapes (f4 is a significant drawback compared to f1.8 and f1.4 for the Arts, respectively).

Nice shot you got there, BTW! I also got a subject in mind - a waterfall that I need to get close and personal to. So far, however, my best shot is with the 14 Art, stitched. Maybe I'm missing something, but why don't you just stitch the scene above, with the 17 TS-E? In my case stitching is challenging due to the water movements(?) and distortion, but to me it looks like the TS-E could do very well in the scene above, no?

The picture I displayed is just to show the area. The trouble is that even with shifting of ts17 its still not wide enough - it requires moving the head which is not good for stitching. Because the mountains are so close and so big.

And when shifting and stitching something so close I need to leans back and then stitching goes all wonky because the mountains are so close and high and the perspective gets distorted. And stitching cannot overcome.






I was just on the left of the lake looing at a corner

I think the sigma 12-24mm v2 is lighter than the tse-17 and ef11-24 or the art version, but not as good as any mentioned.
The iris is interesting, but will be limiting as you already know; so you will have to compromise somewhere

TS17
$2200
8 blades = 8 sun bursts - not as good
1.8lbs which is lighter than the 12-24 f4 art but more than the irix
capable of 11mm stitched to extreme
now bowed trees when at 17mm

But unless I was really sure - I would take ts17 and 24-105/f4 backpacking. I was just thinking I would add Irex 11. The ts17 is always better than sigma 12-24 or canon 11-24 because it has shift - for me. I can shift to edges and stitch to get 11mm or so as long as the object is not too close. When it is too close though - the 11mm would be handy.

EJ Peiker reviewed the Irix and thought highly of it. Seems like good a value lens, well built. Saves a ton weight and money too.

Yup, and the Irix should humiliate the 11-24/4L at 11mm, in terms of resolution and distortion (which when corrected optically is equal to more output resolution).

I'd definitely take it first, if I didn't already have the 11-24L (and it's on my 'I'll get to it' list already).

Thanks Pixel Perfect - I did not see that review until you pointed it out.

http://www.ejphoto.com/Quack%20PDF/Irix%2011mm%20Review.pdf


Summary:
Tested on a7s, it reached 4000 at centre and when fstop moved up to f8 near 4000 at edge
notable quote "But
in architectural or real estate applications, one will have to take into account that about 8
degrees will be lost off of the angle of view if truly vertical lines are desired - consider both
lenses 12.5mm lenses if linear correction is necessary.".


It looks pretty good.

He also reminded me that voigtlander 12 is another possiblility.
$900 usd
12mm
F5.6
0.6 lbs plus adapter
10 blades so 10 sunbursts

That would be the winner in price, size and weight - I am off to find comparisons.

If the Sony E mount is brought into the equation, don't forget they now have the native 12-24/4 lens, which looks pretty good in the Photozone test.

The non-art Sigma 12-24 ii is about half the weight of the 12-24 art or 11-24, but not nearly as good. Mine was pretty good at 12mm, but very weak at the long end....so just maybe you might be satisfied shooting it at 12. It has some funky distortion at that focal length though.

Yup, e mount is great for the wide stuff right now - the Sony 12-24 f/4 beats the sigma art at less than half the weight! Plus there are 10, 12, and 15mm primes from voigtlander that are excellent, tiny, and around 350g.

Yeah if you go the Sony route, there are a nice bunch of small UWA lenses that are good price and indeed that new 12-24 is very nice and half the weight of the Canon, Sigma 11/12-24 lenses. Also pretty good price, although itís. built down to a price.

I donít if itís true and itíll cost and weigh a lot but there are rumours of a Sigma 12 f/1.4. I canít see how you could make such an extreme WA so fast and lens that is highly corrected without it being massive, bigger than the 14 f/1.8 and a lot dearer. But who knows itíd make a remarkable low-light interior lens and be fantastic for astro

I am not going the sony route - I tried that and feeding two systems that are not quite perfect (hate the sony menu, battery life, small body, does not work with my 600v2 --- vs having to use the irex 11) .

I did some looking and the classic voigtlander 10, 12, 15 will not work on Canon 5dsr because the bayonet mount would interfere with the mirror. Why would I go voigtlander digital 10,12,15 - they are as big as the irex and don't come in canon mount.

[16:9 tests voightlander 15 in canon 5d by lifting the mirror and inserting a nikon version below the mirror and turning the mirror up feature on - and finds the voightlander 15 performs better than the sigma 12-24 except for vignetting but I am not about to risk my mirror and shove stuff into my camera in the field when I switch lens

http://www.16-9.net/lens_tests/15mm_test1.html ]

So sigma 12-24, sony 11-24 or irex 11/f4 - this is a slam dunk (irex) for me because mostly i prefer the ts17, ts24 when its wide enough or I can stitch. And the irex is 1/3 the price for same quality if I believe the referenced reviews above.

Well, if you have no objections against MF - and judging by your profile, you don't - then it's the Irix, otherwise the Sigma would have been worthy of consideration.

Truth to be told, there's also the Laowa 12mm f/2.8... (Photozone test: http://www.opticallimits.com/canon_eos_ff/981-laowa12f28)

Thanks Snopchenko - I saw the reviews of Laowa 12/2.8 - they are pretty good as well.

$949 USD
12mm
f2.8
7 blades = 14 sunbursts
1.3 lbs - best of lot
Seem close in quality with Laowa being slightly better.
Both pretty good for coma.
http://www.imaging-resource.com/lenses/laowa/12mm-f2.8-zero-d/review/
http://www.photozone.de/canon_eos_ff/981-laowa12f28?start=2



So price (irex $400 cheaper) vs 1mm of extra width for Irex and f2.8 advantage vs f4 advantage for Laowa.

Tough (= good) choice. Laowa would be better for astro. Irex would be better for landscape (wider) with 0.3lb extra weight for hiking and $400 cheaper and easy nd file adding through 29mm x 29mm back slot.

Although if you have straight up and down lines (architecture) you likely are better to go with Laowa 12 because it has fixable distortion of 1.3% vs Irex 3.3% and if you need to fix the distortion -- the lens performs like a 12.5mm lens because of the cropping needed.

So - Irex for price and mm for landscape and Laowa for astro and architecture.- Scott

Now I am thinking.....
