Viraj,
I don't want to spoil the party, but please note that Birdforum is one of the last redoubts for the cult of the Habicht Porro. Of course, Porro prisms can be part of a superb binocular design, but when they're combined with a 100 year old Kaspereit eyepiece design and a fast crown and flint cemented doublet some well understood performance limitations will inevitably follow. Anybody interested in buying a Habicht after reading praise on this forum should be certain that it can be returned with no questions asked, because compared to state of the art modern binoculars virtually every performance characteristic of the Habichts is compromised, except for the very high light transmission and color accuracy provided by Swarovski's current AR coatings.
The measured off-axis astigmatism of the 8x30/10x40 Habicht Kaspereit eyepiece is a whopping 9 diopters near the edge of a 60º field, compared to a fraction of a diopter near the edge of a 69º field in the current NLs. The measured full aperture resolution of my two 8x30 Habichts is mediocre due to high longitudinal CA and spherical aberration, exactly as expected from the objective design. Eye relief is too short for eyeglasses, the prisms are so undersized that one prism edge intrudes into the exit pupil, an obvious vignetting shadow is visible at the field edge in subdued light and there is strong veiling glare from insufficient baffling in the 8x30. None of this seems to matter to the fans when a binocular is one of the last survivors from a Golden Age.
