I've had the blackstone version for 3 months now, and I really like it. Of course, it's built like a tank, weather sealed, fast, super sharp, and has less chromatic aberration than any other lens I know, but somehow it's the little touches that most impress me:
  • The marker for lining up the hood is valid when reversed.
  • The filter window is captive so you'll never lose it.
  • There's a very subtle click stop at infinity and, like the distance scale, it's bang on.

I shifted the sensor all the way up for this shot, so I had to remove the hood. Even with Pixel Shift, and beyond the nominal image circle, the corners hold up really well; I've uploaded this one at full resolution.

I'm sure the Austrians and Swiss are laughing at me, but this sort of tunnel portal is exceedingly rare in Denmark. Exotic, even.

Maybe rare in Denmark, but I cannot remember ever encountering such an under-the-road footpath via a tunnel for a stream anywhere in the USA. The gauntlet is down, someone show me that I am wrong.

This is a panorama of 9 photos made with the Irix 15mm, firefly version, and a K1 of a friend of mine.
I did and proccessed the photo. The original File is a *.tiff of 2gb

Well-executed night shots, regardless of the lens used.

Check this out;

Google Maps

North Riverside, Wichita, KS. Path goes under the roadway next to The Little Arkansas River. Not a stream exactly but it's a pretty small river, maybe 50 feet across most of the time.

That is ONE. I'll wake up when we collect one for each of the 50 states, although they don't need to be distributed one per state. BTW: There might be one or more in Central Park, as I vaguely recall (well over 40 years since the last time I wandered there).

Sorry, you're just not my type. And I'm spoken for. Want to please me? Send me a PM offering to sell a mint 600mm f4 for $250.

Great thanks, very well done I agree !

Now I will make my order as well....

Let's do some sunbursts with it to see how much flare resistant this lens is!

For those interested in starbursts, have a look at this interesting thread...
Best "Starburst" on lenses? - PentaxForums.com

The fact that the Irix lenses has 9 rounded blades may not help to get nice sharp star points, but odd number of blades will give starbursts with twice as many points as the lens has blades (here 18 points)


Read more tech data of the 15mm here Irix - Meet the Irix 15mm f/2.4.
and 11mm here: Irix - Irix 11mm F4.0 officially announced - Press release

I have been thinking of getting the Irix, and it seems to be a "love me, love me not" process. I see the photos and I want to get it, then I read about decentering problems, and I want to wait... Just wondering if there are any statistics on the ratio of problem to no problem lenses...

Yeah, it would be great to have feedbacks from the users who had the decentering isue, and how Irix support was cooperative or not...
