Ted,
One of your cons was that you'd rate the BX-4 in focus sweet spot at about 50%. Then in summary you say that BX-4 presents a sweet spot clarity that is close in performance to your superb EL8X32SVs. Are your SVs not much better than 50% sweet spot in focus?
Upland,
Sorry for the misunderstanding, please let me rephrase.
My SV Sweet Spot, with their field flattening eyepieces, fills the whole FOV! The BX-4s Sweet Spot is about 50% of their total FOV, and in that smaller on-axis area, their clarity and performance remind me of the "same central area" of the EL 8X32 SV!?
IMO and to my eyes, the EL 8X32 SV has 100% usability of their FOV. The BX-4 has a usable 50% of their FOV, the rest of the outer field being a slow, gradual roll off in sharpness and clarity!
Hope this helps...
Ted
