You have to buy these lenses from Pentax. Both lenses are a joint effort by Pentax and Tokina and part of the deal seems to be, that Tokina sells only for other mounts and Pentax exclusively for K-mount.

it will be listed under pentax. The typical retail price for these 2 lens should be around 799 and 1199.

There is a samsung equivalent pf 10-17 in ebay now only for <AUD600.

it's just like the 18-55 but with more FOV coverage, much better sharpness and contrast and less distortion at wide open. hope that helps.

Evening, I have an older post that compares 3 lenses including both the 12-24 and the 10-17 FE in approximately the same picture. Its at night, so the fish eye (FE) distortion is not as apparent.

https://www.pentaxforums.com/forums/general-photography-techniques-styles/834...panoramas.html

I do have to admit for your needs, this is somewhat of an unfair comparison. I was comparing the relative detail obtained with each lens in a stitched panorama use. All the lenses were in a portrait mode, with the exception of the 10-17FE.

To understand the FE effect in an image you really need to have some images done in the day light.

The 12-24 is extremely sharp, and I find the distortion at the edges well controlled. dpreview had a comparison and found it sharper than the Pentax DA15 Limited. Bottom line is - it is a very good lens. The field of view is 100 to 60 degrees.

The 10-17 FE is a fish eye. Its field of view is 180 degrees to 100 degrees. So in regard to the FOV the two lens complement each other, and do not overlap as their focal lengths might indicate. The 10-17 is somewhat of a specialty lens. It does have an pronounced fish eyed effect at 10mm, decreasing to a pretty well controlled FE effect at 17mm. At 17 it does appear to take on characteristics of a rectilinear lens - however the FE effect is still there. You can defish the images with post processing software.

Thanks guys
I have been away........
I am pretty sure I will go with the sigma 12 -24.....the reviews are very favourable.........and I would prefer less of the fish eye effect if I can get away with it.
cheers
