Bokeh Test: iPhone, Ricoh GRD, Fuji X100S

I've been testing different cameras recently and I've been talking about depth of field and the importance of it in certain types of photography. The more the better if you're shooting food or products, especially if you're trying to keep everything in focus (which is usually the case). Let's begin by taking three different cameras with 3 different sensor sizes: iPhone 4 with a 1/3.2" sensor, Ricoh GR D IV with a 1/1.7" sensor, and the Fuji X100S with a APS-C size sensor.

I've taken the same image and tried to see how much of the food is in focus from front to back. I'm sure the waitress thought I was crazy, but hey, it's sushi. It's not like it's going to get cold! I focused all three images on the salmon skin rolls on the bottom left, and see how much depth of focus we can get by looking at the fruit in the middle, and the raw tuna and salmon on the top left. Alright, let's take a look at these pictures!
