pentax's video is not that great, still trailing badly among the dslr competition of canon or sony.

Yeah the 1D's are pretty big camera. I understand why you would want a smaller more compact body.

Pentax do have good primes. Got to admit that the da limited line of lenses are pretty darn small and compact.

PS going form a 1d to a t2i is a big change. The 7D is pretty rugged like the 1d. The 60D is just a little bit behind as the weather sealing is not as good as the 7D. But it might be that you are so uses to the 1d that a smaller camera no matter which brand will feel off.

Well, not wanting any part of any philosophical discussion on brands, I understand what you mean. Canon has three distinctly different user interfaces on its three levels of camera so one who is a Id user may not necessarily feel comfortable with a 7D or 60D.

As for the quality of lenses, the FA limited lenses are full frame designs (only DA labelled Pentax lenses are APS-C only). These three, the 31, 43 and 77 are probably the best lenses that Pentax makes (there are also DA Limited primes that, along with the DA* lenses are very good APS-C only models, however the DA Limited lenses have smaller apertures than the FAs, mostly around f2.8). Limited lenses are not weatherproof but are very good however you will have the 1.5 crop factor to deal with so there is no wide angle lens in this group. As a financially "limited" owner I have the next level of lenses, the DA 14mm f2.8, the FA 35mm f2 AL, and the FA 50mm f1.4, of these the 35 is the best wide open, the 14 has significant distortion out near the edges and the 50 is a little soft wide open but produces a lovely feel to its images.

My two cents. Look to the FA Limiteds first unless you need a wider lens (there is a DA Limited 15mm f4) or a longer lens (a DA* 200mm f2.8 would be nice).

I look forward to your decision.

Pentax still do not have a 70-200 2.8. And the ef 85 1.2L with a good copy without any focus shift is insanely good wide open at F1.2, do not think any of the pentax lenses can match a f1.2 with shallow dof that it can produce. f2.8 does not match f1.2 in shallow dof or low light ability.
On the other forum there was quite a discussion recently about fast 85s. I don't think there has been a head to head comparison between the Pentax 85/1.4 and the Canon 1.2L, but that's in the main irrelevant as the DoF is going to be as small as anyone would want under normal conditions. However the 85/1.4 is not available new of course.

It's not all about resolving power - though I can crop 1:1 with the 43 and it still looks like an excellent uncropped shot - the images from the 31 / 43 / 77 are absolutely superb and on a K5 can be printed at virtually any size you could feasibly want without getting into the realms of huge prints for advertising.

It isn't about which lense has the greater resolving power it's about the quality of the images it can produce - and the images from those three lenses stand up against those from just about any other lense.

I began reading about the K-5 a few days ago and it seems to fit my needs/wants pretty well. It is small, rugged, has good ergonomics and the lenses are relatively cheap.
If you liked the D7000 then the chances are you'll also like the K5. Similar size, the K5 has better ergonomics (IMO) and is fully weather sealed (it's interesting to check to see where the actual seals are in different cameras, some that people claim are fully weather -sealed have unsealed spots). The cameras use the same sensors bar any in-house tweaking Nikon or Pentax may have done - which means both have superb high ISO capability. Probably the AF on the D7000 may edge out the Pentax AF - however we may be talking about degrees of excellence here - unless you are planning to use it for sports shooting / birding, and looking at what you have now I'm sure that's not even a remote possibility.

Lenses : generally it seems you get more bang for your buck from Pentax lenses than the expensive high end Nikon / Canon versions.

As Sho said the video is still behind it's competitors.

It is still a step down. I have not even gone into the fact that all the L lenses are weather seal and the Limited are not. There is a difference at 1.2 compare to the 1.8-2.8 of the limited.

If you want to take about a great 24mm or 35mm the ef 24 1.4 or the 35 1.4 are very good primes and very sharp. And weathered seal. Not a option with the pentax. So the k5 will be weather seal, but the lenses will not. Only a half rugged system. The FA limited are close I am sure, but they are not 1.4. And they focus pretty darn fast as well with the USM.

None of which the OP has so those lenses are irrelevant. Your exact comment was :

They are good lenses but now where near as good as the L glass you have.
My assertion is that the 31/43/77 ARE as good as he has now .... if not better.

I have actually found a direct comparison of the Pentax 85/1.4 vs Canon 85/1.2L. He also had the Zeiss 85/1.4 which from his comments clearly didn't perform as well as these two.

Very interesting :

Suffice to say that the Pentax doesn't outperform the Canon at long range as clearly as it does at close range.

my assertion is while the DA and FA limited are very good and compact lenses, they are not quite as good as the L, which are is my point. I also mention those lens to match up with the 31mm and 43mm. If we where trying to match up what the op has currently. You really can not with the current pentax line up. The 50 1.4 optically and build wise is equal, but focus speed wise no.

Here is quite a nice guide to Canon vs Pentax lense line-up in 2009 (available new and not including 3rd party or legacy lenses) :-
