The push for lead-free optics seems based more on concern about the possibility of lead contamination from the manufacturing process or recycling process rather than the glass itself. Environmental issues aside, most modern bins have lead-free glass, and I've noticed a degradation of image quality, particularly increased CA, in some lead-free optics and have read technical reports that verify this observation, which I posted on another thread. At 8x, the increased CA might not be that noticeable, but at 15x, it would. I think the main reason why optics manufacturers are increasingly using HD or FL or ED glass in their bins - including Swaro, with the new EL - is to compensate for the greater CA in lead-free glass. So I was wondering if Ben or anyone else had knowledge of when the changeover to lead-free glass took place in Swarovskis, and if they see a difference in the amount of CA from the older version of the 15x56 SLC compared to the "Neu" version.
