Good point regarding comparison to the Q. Guessing the 23mm T and the camera body together will probably come in b at about 3500.00 What one gains over the Q is ability to change focal lengths.
I am pretty sure the lens on the X 113 is a better one stopped to f2 than the 23mm T. There is an AA filter on the X but it is a weak one, and a really nice pop-up flash that can quickly and easily be dialed down for fill purposes. With briteline finder, this could be had for $1400. Of course I am beating a dead horse
