AF Badman has a 6-base (flatter) frame, so I'm fairly certain the lenses are not interchangeable. - eddyc
Polarized Badman™ (Asia Fit)
The all-day comfort of lightweight diecast aluminum blends with the subtle flexibility of O MatterTM for an iconic look that honors the core of our culture, including the DNA that drives our relentless obsession to shape innovation with style.
Inspired by the attitude of our famed X Metal® collection, Badman™ combines the glare-reducing performance of HDPolarizedTM lenses with XYZ Optics® for unrivaled clarity at all angles of view, even with a full 8.75 base lens curvature that blocks peripheral sun and wind. We tooled the comfortable Three-Point Fit with the gripping power of Unobtainium® components and the precision of custom-engineered spring hinge mechanisms.
I wouldn't believe everything on O.com. The 6 base frame curvature is the only reason I can wear the AF Badman. Even with larger nosepieces, a standard fit frame would sit on my cheeks.
Oakleyforum actually came in handy on this one. See the linked thread:
This prompted me to have my local O-store special order a pair for me so I could try them before buying. The frame really is quite flat... almost like a chunky aviator. Fits great, too.
Quick comparison... side view of the AF from the kineidou site (Japan):
Side view of the standard fit from O.com:
Maybe the o-matter nose piece of the AF model that connects the orbitals is flatter than the regular one which gives a flatter look and feel but the lenses are the same thus be exchanged.
I made a mistake getting an AF Badman thinking its just the nose piece difference from my GF Badman. I ended up returning the AF because of disappointment.
Here are my findings while comparing the 2:
1) The GF has a rectangular lens while the AF has a squarer lens. (therefore they are not interchangeable lenses)
2) The GF has a more curved lens while the AF has a flatter lens.
3) The curve is more prominent on the GF's frame and nose bridge while the AF is way flatter.
4) The nosepiece difference as you guys already mentioned

Sitting on a flat surface, the GF is further away from the camera while the AF is closer to the cam.

It is clear that the lenses and nose bridge can not be swapped but how about the nose pads? - gamb-o
Even if someone needs a few mm of clearance for a GF model, you cannot just swap a nosepiece. - NotyourTypicalOptician
