Thanks Des
I was looking at that lens but he was selling it as a kit with K5 plus 2 lenses for $800 on facebook, then started to sell them off individually as he had with no response as a package. I wasn't sure what I should be looking at - that's when I found this site looking at reviews. Des your advice has been invaluable.
I shoot in Raw - learnt that one real quick.
My first real shot with the new lens at the start of yesterdays storms brewing overhead. Couldn't get out due to working.
Will look into the 50mm lens.
