So far #2 looks most interesting. We like the composition and detail on the rotors. We like the detail in the center box very much - it implies precision, Would it be possible to integrate the feel of a camera in that area? Could we see some other fonts for the blue? This font is interesting, and bold, but we need more ideas. We like the alignement of 2 & 3 vs. 1. Great start.
Is it possible to have 2 flavors of this logo? One that is just like this, and one that replaces the orange with grey (so that it can be printed/sewn) on an orange background? Also, is the blue you are using 279c as specified? use some black if you need to.
