Irix 15mm f/2.4

[simsurace]

Just because I'm not seeing the problem now does not mean that I won't be bothered by it later or that it is not present.
I see some blurriness in the corners that is roughly what I have seen from other ultra-wide lenses (some like the 16-35/4 sample I had were much worse than that, others are perhaps slightly better like the 20/1.8 and 18-35 but I am not sure since I'm comparing vastly different shots here). One of the two lower corners might be blurrier than the other but I can't tell because the pavement is not the same on both sides. The same is true of the Canon 11-24mm lens sample above. The right corner seems blurrier to me but the pavement is different on both sides so I'm not sure I am seeing things correctly. So is the Canon lens not decentered?

I am just not putting too much weight on these samples, I want to try the lens myself or see a lab test under controlled conditions before making any decision.

The samples shown aren't good enough for me to tell.  And, regarding the 5D camera, I have no idea what 5D shots look like unsharpened.  Others may be fortunate enough to have had experience with Canon gear.

Hi,

Looks good like the other Review. Diatortion and vigbetting seems Well Controlled. Sharpness is good! Missing shots at Infinity and a Review about the Focus Lock!

I am now looking for some nice wide angle lense for night photography. I was amazed by this Irix lense in lot of reviews and this is actualy last forum/webpage/review/comment i read in several days and it left me in doubt.

Since there was claim, that the pictures posted here were not samples by Irix, that means anyone could make a picture, upload it and claim that those pictures are from that lense. Who will claim otherwise?

Official sample gallery is another story https://www.flickr.com/photos/irixlens/sets/72157664815786113/with/29880254493/
Another reviews on youtube are kinda very nice about this lens, so....

Do anyone used it, tryed it? Can anyone tell me real story?

And if not, can you please point at another direction, to onether lens which I can use for nice night photography? I already read too much propably. Was thinking about

• Nikon 14-24mm f/2.8 (no one actualy said bad thing about it, but some reviews comparing it with Irix said it is almost equaly good)
  Samyang 14mm f/2.8 (widely used despite all its flaws)
  Samyang 14mm f/2.4 (all praised, but no for that kind of money)
  Irix 15mm f/2.4 (from here, all those posts, looks like crapy lens)
  Tamron 15-30mm f/2.8 (have no idea)
  Sigma 14mm f/1.8 (it has huge coma and astigmatism)

The 14-24/2.8 is the only one on your list I have used.  It's a great lens except that it often generates non-traditional ghost flare spots from bright point sources, like the sun in daytime shots.  Mine did well, flare-wise, in the very limited amount of dusk/night shooting I did with it.

I rely on my Zeiss 15mm f4 Distagon (but for landscapes mostly). Excellent lens
