Plans usurped!

I planned to buy a Pentax 12-24mm F4 off a forum member all was going swimmingly or so I thought! Anyway I had previously owned a Sigma 8-16mm from my D7000 (Nikon) and it'd nagged at me when comparing the two Lenses, even resolution across the frame and constant aperture (Pentax) and WIIIDE too wide? (Sigma), I'd kinda settled on the Pentax and must have mentioned it to my long suffering Camera Widow (Partener) more than just the once
She came home yesterday evening from a "Shopping" trip to the toon with a brand new Sigma 8-16mm in pentax fit (Handy!), having done quite a good deal with the poor salesman in the Camera Shop (Poor guy didn't know what hit him probably!) Not quite as good as the SRS Ebay offer but not far off, she managed to knock a hundred quid off and it has been bought with the proviso that "Youre not selling it, even if you change Camera's AGAIN!"
Had to change my Sig back and everything...

She is obviously FAR TOO GOOD for you. My wife is obviously from the same DNA pool as she is very supportive of my fancies.

Burden is now on you to produce the minerals and show the rest of us what you can do with said optic.

Best regards and happy new glass.
