Easy answer would be something like this...
Portrait - Canon 50mm f1.8 -> Pentax FA 50mm f1.4 or Pentax FA limited 43mm f1.9
(own this) FA 50mm is quite plastic lens, image quality is nice. Bit soft wide open. Price is the big question mark, because this "shouldn't be" a expensive lens.
(haven't tried) FA 43mm limited build and image quality from what I hear is top notch. Expensive.
Wide - Canon 10-22mm f3.5-4.5 -> Pentax DA 12-24mm f4 or Sigma 10-20 f4-5.6
(own this) Pentax DA 12-24 f4 is sharp and very good quality wide zoom, bit bulky. But I have been very satisfied. Expensive
(have tried) Sigma is very good also, extra 2mm is quite a lot!, My boss has this for Canon and it's very nice.
Zoom - Canon 70-300 f4-5.6 -> Pentax DA 55-300mm f4-5.8
(haven't tried) I have heard only good things from 55-300mm lens. Internet praises it and also my work mate
Hope this helps, I'm tired so I won't write longer reviews, this forums lens review section is WORTH a visit!

Portrait - Canon 50mm f1.8
Wide - Canon 10-22mm f3.5-4.5

I've looked through reviews but wanted to hear from the experts - what would be the equivalent for a Pentax system?
Thanks!
