I did not took the mount of the lens. If you want to see how the lens look like and how it is on the k1. It can be seem from the above post, there's a link which will bring in to it.

Copy from above,
"As mentioned in the thread here, I have collected the lens."

Hope it helps. It will fit ur k5iis well.
Thank you to much it looks great on the k1, I hope it looks the same on my iis

Finally, I have a question about the lens, Does it have the lever to control the aperture??

Thank you again.

Cheers Jose

Hi Jose,

Yes there's level to control the aperture. So it's like the newest da/dfa lens but without auto focus and the aperture ring...
Aperture is shown and can be adjusted with your dial.

Hope it helps..

To clarify in different wording: the Irix aperture is controlled by a camera dial, and is closed automatically when the shutter is triggered. Correct? It is important to know, as I believe the new Venus 12mm "ND" - not yet available for Pentax SFAIK - has an entirely manual aperture control via a lens ring - no camera body control of aperture setting and manual stop-down to shooting aperture (use "A" with aperture ring enabled for exposure). Shades of the 1950's when I started with an Asahi Pentax "S" that had only preset or manual aperture control on every lens.

Yup, this is correct, the Irix aperture is controlled by a camera dial, and is closed automatically when the shutter is triggered.

Yes of course it has helped me!! And i think this lens will be mine soon!!

I answered because I thought it was completely manual and doesn't allow to work in Av mode, but I was mistaken!!

Than you

Hmm, if anyone has the firefly version - is the front element really not weather sealed? Just wondering if anyone had experience with using it in bad weather) pics look great, design of the lens is stunning!

Looks like an awesome lens so far. Has anyone done some astrophotography with it on the K-1? The only thing I'm waiting for is to see how well coma is controlled. If it's good then it's definately a must have lens for me.

Does anyone yet have both the Irix 15 and the DFA 15-30? Comparisons would be useful.
