150 grabs look horrible.
Compared to the A1 and EX3 the 150 looks like up-rezzed video. The most obvious is in the details of the grass. The A1 and EX3 show much finer detail in the grass than the 150...
EDIT: I just read that the OP shot each camera in stock setting. Okay, now this test is entirely useless to me. It is basically a test of the image quality of the 3 cameras at their stock, out of the box setting.
