Will the SMC DA* 50-135 mm f2.8 ED IF SDM suffice as an only lens?

You can tell him that "Point and Shoot" is a behavior not a camera.

I have a bunch of Fuji's and I like all of them and still use them.   Fuji has always done a good job of pushing photographer friendly features into their F and S series.   But given that, you'll love the K-5.   Its a comparatively small camera compared to others in its class, and smaller even than my Fuji S100fs.

A lot depends on your typical subjects.   For me, I find that most of my stuff is done in that 18-50 range, or I need a ridiculously long 600mm tele, with little inbetween.   50mm on the K-5 is ~75mm on APS-C, so that's pretty long for indoor use.   If you were getting a K-5 kit with the 18-55 wr, that might give you wide when you need it.    Its a lens I've wanted, so sure, I vote "yes!" as this is a democracy, apparently.
