[QUOTE="brocknroller, post: 3149930, member: 665"] Deja vu. The 70* AFOV EII appears brighter to me than the 60* AFOV SE. The color balance is slightly different between the two, with the EII being slightly "warmer," which could affect that impression. Reds are slightly orange-red in the EII, deeper red in the SE. However, the SE's objectives are 2mm larger, given the same transmission coatings, and a similar number of surfaces, the SE should be brighter, but to me, the EII's image appears brighter, I think it's because there's more [I]background[/I] around the target. More leaves and other surfaces reflecting light in the background. Try this experiment. Take a 5"x7" photo and put it in a 8"x10" frame with a 5X7 matte. First use a white matte, then a black matte. Stand at a distance from the photo. Which appears brighter, the photo/frame with the white matte around the photo or with the black matte around the photo? [/QUOTE]
