Cool thread. I've been wondering about this. Two follow up questions though:
- Measuring lenses w/ a vernier caliper: They are 30mm tall; maybe 29.5mm. I measured Ti Wire 2.0, Square Wire 2.0 non-SH, Square Wire 2.0 SH, and Titanium Square Wire 2.0 SH (btw. SH and non-SH lenses aren't interchangeable). Does that mean the 30mm version are .5mm taller to fulfill Australian law, or are they actually taller than 30mm? I would assume the latter if people actually notice a size difference. Can someone measure?
- How tall are the big square wire lenses then?
- What are the differences on the various revisions of Square Wire 2.0 SH?
