Superb images, particular #2 and #3, agree with John that they'd have a tad more impact if they were a few shades darker.

Have you considered the Samyung 14mm F2.8 ? It is manual focus, but the DOF also takes care of a lot of it, just set it to F8 and shoot. Somewhere around £330 new from SRS.

You'll have to factor in it'll effectively give you a 21mm lens with the crop factor, but the Sigma 10 - 17 will effectively be 15 - 25 ish and won't give you F2.8 !

I've got one, it's a cracker of a lens.

Yes, see below pinched from SRS's web site, but you may get some vignetting in FF thou

" When coupled with an AF lens, the autofocus operation can be performed by the main lens. This rear converter works perfectly with both the camera-driven AF system and the lens-driven AF system (such as the SDM- and DC- series lenses). The camera’s firmware must be updated to the latest version before using the autofocus function. Compatible camera bodies are: K-S1, K-3, K-50, K-500, K-30, K-5 II, K-5 II s, K-5, K-01, K-7, and K-r. Autofocus is possible with a Pentax lens having maximum aperture of f/4 or brighter "

Good stuff, it still might have not been enough support thou at your shutter speed of 1/180th sec even at 800 ISO

If that was handheld, then that may be the reason for the softness at those extremes, worth trying again mounted on a tripod perhaps if poss

LOL, it was a genuine errors I've not entered before, but on the other hand................
