Hope you dont mean to say that a 60d with a 15-85 is the same as your PS: Either you have a PS which no one else but you can buy, or youdont really know what you are talking about, here.

I guess you didn't read what I wrote carefully because by P&S I was referring to the "kind of shots" that you can do with a 15-85+APS-C that you can't do with a prime.



If it's serious landscapes, portraits, action, etc. you can do all those with a fast prime just as good and most of the time better than with a zoom.



So the kinds of shots that you can get exclusively with a 15-85+APS-C will have:



* Overall shake (due to the reliance on IS, instead of taking a tripod and locking the mirror up)



* Little subject isolation (due to the slow aperture)



* Inaccurate focus because of less light going to the AF (so forget any real tracking but DOF is so big like on a P&S or a handycam, tracking is not even a real issue)



* Subject blur except in good light (again due to slow aperture)



* Bad bokeh (the simpler optics of primes in combination with larger apertures produce better bokeh)



* Heavy CA (due to all the extra glass etc.)



So, effectively, the shots that you can do only with a 15-85 IS that you can't do with a fast prime are P&S-like, lazy-tourist shots. So for that kind of thing I much rather carry a smaller P&S like my Nex-5.
