I finally decided to buy a second hand pair of Zeiss Conquest 8x32 HD through the Birdforum. I have compared the HDs and my old 7x42 Dialyt T*P* today. First, when looking at dead objects such as tree trunks, rocks, distant antennas, buildings etc, I did not notice much difference. I felt I could resolve the same details with the 7x as the new 8x. But then I began to look at birds. That was the difference I had hoped for! Suddenly, from just being a bird in the view, it turned into a much more experience of the animal. Sure, I have seen the same when using my 10x bins (Bushnell Ultra HD), but they instead don´t have the light that I feel is needed even during day to lift out the bird in the image. Certainly, I could have gone for a 10x42, but then I am out of the scope with this purchase. I wanted something smaller and handier than my old Dialyt, but with equal or better performance. I think I got what I wanted. [Someone suggested the Nikon 10x35 Eii, and maybe they would have done the job, but I did not want to go for another pair of 10x having both the really nice Bushnells and the Leica 10x25]
Yesterday night I also made a brief test of the low-light performances of the Dialyt vs. the HDs. I was wondering if the modern HDs, as they appear brighter during daytime than the Dialyt, would now beat the Dialyt despite the 6mm pupil of the latter. However, the Dialyt was noticeably better in low light. I do not understand how the HDs can have a brighter view during day than the Dialyt, but then drop off in the light intake compared to the Dialyt when it gets dark?? Maybe it is due to that the Dialyt has some kind of fuller colors, a bit more yellow-green tint (although not disturbing) that make the image appear darker during daytime than the somewhat whiter image of the HD. In any case, I am happy that my Dialyt holds its ground as low-light performers. I find my new HDs are the better binoculars between the two, but I have a special affection for the Dialyt, they are like a vintage car. Modern cars perform better, but the old classics can offer a very nice ride [I once went with 8 (!) others in a huge open cabriolet from the 50s (or 60s, I am no car expert) and it was like floating along in a boat. It had nothing to do with riding in a modern car].
So, birding during daytime: I´ll love the HDs.
Looking for wolves at night: I´ll stick to my Dialyt.
