Hensoldt Diagons

I am a fan of the Diagon 8x30 binoculars from Hensoldt. I have 6 copies, 3 civilians and 3 military, all 8x30 and all bought in e-Bay. It has always fascinated me that these binoculars manufactured in the 60s are so good optically and mechanically so that they perfectly resist a comparison with the best modern similar binos, such as Swarovski Habicht 8x30 and Nikon 8x30E. My first binoculars were Carl Zeiss Jena's Deltrintem, also from the 60s, but the Diagons seem better to me. The models Jenopten 8x30W of Carl Zeiss multilcoated have better contrast, but the image is somewhat yellowish. In general, the Diagon are light and well made, have an extraordinary central sharpness and present natural colors without dominant coloration.

However, some of my Diagon specimens have a problem caused by the passage of time: the lenses of some doublets (objctives and lenses of eyepieces) have partially detached, towards the edges, which, without having an appreciable effect on the image, it is annoying because they present colorations or irisations produced by interferences of the light when reflecting in the split surfaces.

Another problem that I have found is that the reticle present in military models tends to get dirty, and this is not the case with the lenses, so I appreciate Diagons  without a reticle.
