Conclusion: That is the water repelling characteristic of surfaces, to simply let water drops pearl off as well as repel dirt. LotuTec® acts as protective coating and cleaning and care is made much simpler. This technology has been used for a while on Carl Zeiss spectacle lenses and has now been developed for most of the Zeiss Victory Binoculars range and is used on the Zeiss 8x42 Victory FL Binoculars
Conclusion: The Zeiss Victory 8x42 T* FL fared in this test very similarly to the 10x42 model - it is enough to glance at the list of pros and cons and at the final score to be sure of it. To tell you the truth I thought a different eyepiece construction than in the 10x42 model would correct the distortion in a much better way but unfortunately it didn’t happen. The distortion is huge and it remains the only serious flaw of the tested Zeiss.
Pros: high quality casing,, very good transmission,, good coma correction,, splendidly corrected chromatic aberration,, almost imperceptible astigmatism,, perfect blackening,, very low light fall-off on the edge of the field,, good whiteness rendering,, high quality optical elements and coatings,, minimum focus already from 1.75 meters,, circular exit pupils,, wide interpupilary distance range.
Cons: a bit too high distortion,, very intensive false pupils; it shouldn’t have happened in a piece of equipment of this class.
