The reduction of color fringing on any object should provide for a sharper image...both apparent and actual. In which case it would stand to reason that an 8x ED binocular might outperform a 12.5x assuming the 12.5x does not control color fringing very well and the 8x does.My experience with the 7x42 Trinovid BN and the 10x50 Meopta Meostar was similar to Owen's. I utilized both for hawkwatching a year or two ago. In such a situation there wasn't a single instance I can remember where the 10x actually showed me something that the 7x did not. Now the 10x50 did show notably more color fringing than the 7x in that particular situation. I am now left wondering if CA was the sole contributor or if Owen's atmospheric conditions comment also play a significant role.</blockquote>
