Not sure what you are looking for here? But, any larger sensor has no problem with studio work. Good lighting technique and a sharp lens with a good low ISO IQ is all you need. Maybe not for "Big Paid Stuff, but, absolutely for personal and Portfolio work.

These are good samples what you can expect.
I used a E-510, (Even an Oly C-5050) in a gals home. Worked great. So it very feasible to get good results, with a little knowledge on a simple 2 light set-ups similar to what you see in these "Franchise Studios" that are popping up all over.

The 2nd sample gallery had better lighting technique. But, even my early stuff was all over the place.  (too dark, lights too hot, lights not aimed right) but, it's doable.
