So I thought Vortex was supposed to be a good quality binocular, so I got both the 8x42 Vortex Diamondback and the 10x42 Vortex Viper to test out. Was outside later in day, weather was gloomy and cloudy. I was focusing on birds in a tree high up with binoculars focused on birds/tree branches with somewhat bright cloudy sky in background and I noticed that the image of bird was not as sharp and crisp as I thought it would be, not even with the 10x42 Vipers, and then tons of purple and green discoloration to outline of birds and tree branches. I googled the issue and it said that was Chromatic Aberration/Fringing. So now I'm really frustrated because I thought these were decent quality binoculars and was not expecting to experience this. So now I'm left wondering is it a binocular quality issue or something else? Any thoughts or info on this?
