It's interesting to read how polarized the opinions over narrow eye cups can be. I eventually sold my Kowa 8x33 Genesis in favour of the 8x30 CL, and one of the main reasons was I disliked the wide, thick eyecups on the Kowa. Just goes to show how ergonomics play such a big factor nowadays when choosing bins. An incidentally the focus knob on my Swaro is just fine, smooth and pretty much how it was on the Kowa.
