If the projected launch date is May, it will probably be at Photokina here in Cologne, although sports optics have taken a back seat in recent years.

I can't really agree. The 10x42 FL was state of the art when I bought mine around 2010 but astigmatism was very pronounced and eye relief somewhat tight.

I see what you mean but think the effect is minimal.
