All would give you equivalent to 50mm FF.
Or how about some of the 24-60 or similar type zooms?
I haven't used the 60-250f4 but the 50-135 is a stellar lens and I don't see why the lack of a tripod collar would stop you using it with a ring flash when you can get L bracket's for the camera body.
The sigma 50mm 1.4 is apparently more like a 43mm or so.. that could be good?
I had a FF camera for a while and the only difference I noticed really was more DoF.. the perspective of the image is controlled by distance and using an equivalent lens gives you the same image.
As for image quality, I found my k5 to be better than the 12mp FF nikon sensor, and while it loses out in resolution to the 5dmark2 it has much better dynamic range.

100% agree about dynamic range of the K5 versus canon.  But I think i am talking in circles about equivalent field of view.

Yes, a 35mm on APS will "act" like a 50mm on FF, but it is not the same optical character as a 50mm magnification.  Its not just a depth of field change either.  For portrait work the way a lens on a specific sensor renders the features does change and look different, and a 35mm lens on an APS does not give the same look as a 50mm on a FF from the perspsective.  it just doesn't do it.  While a 43mm comes close to magnification of a 50mm, the field of view is not as desirable because you lose so much on an APS... Well I think I know my answer, just wish Pentax would give us a FF to use all their awesome lens and sensor technologies on...
