No one has ever established that Swarovski made any substantive improvements to the 8x32 EL. I've certainly never found them lacking, but I didn't play with them enough (or do any side by side tests) with them when they first came out to weigh in on that question myself. My 8.5x42 is fairly early production and my 8x32 is of fairly recent vintage. I find the 8x32 EL very impressive optically. It seems to have all, or nearly all, of the brightness and color neutrality of the Zeiss 8x32 FL, without that model's tendency to accentuate haze (maybe the EL does filter out some blue light without compromising the overall color balance much? The FL almost seems blue biased to me, but maybe that's because so many binos have a substantial yellow/red bias). If not for the substantial chromatic aberration in the 8x32 EL off-axis, I'd consider it optically better than the FL. As it is, it's a draw. In direct comparison to the Leica 8x42 Ultravid (nonHD), I like the 8x32 EL equally well optically. My 8.5x42 EL isn't as color neutral as the 8x32 (some reds seem subdued), but I like it better overall as I've mentioned before. Some combination of extra magnification, greater weight (helps be hold it steady), and ease of use (longer eye-relief, bigger exit pupil) allows me to consistently see finer details more easily than I can with the 8x32 EL, or for that matter, any other ~8x bino handheld.
