I was pretty excited about the variable aperture feature until I decided to plug in some numbers: If you ever get a chance to mess around with a DSLR/ML camera with a consumer "kit" zoom lens with 24mm focal length, you can kind of get a feel on how the aperture settings on the 18Pro isn't that big of a deal. Despite the large f stops on the spec sheet, the sensor is so small compared to full frame, you're not going to get that shallow depth of field (DOF) that a f1.4 prime lens would give on a DSLR. It's not even close to a f2.8 zoom in isolation, let alone a mid range f/4 zoom like a Nikon 24-120/ Sony 24-105. It's basically a 24mm f/5.3 or so lens wide open and then around f/14 stopped down. 24mm f/5.3 still has a very wide DOF so you're not going to get what a full frame 24mm prime at f/1.4 would get you in subject isolation. If anything, it's more of a "kit lens" on a full frame camera. If Apple finally copied the Chinese with a 1" sensor then these apertures would really start to make a noticeable difference.
