    Default Looking a good porro-prism.



    Hello,

    I like the porro prism model more than the roof prism, and I search a good quality but small binocular, like 8x30 model.
    I had one Carl zeiss jena 8x30, what fantastic small bino, maneageable 100%, now I like know opinions of modern Nikon 8x30 II or Swarovski Habicht 8x39, my two desired binoculars…
    Anyone have used they ?

    Best regards,

    tico.

    Hi Tico. I think if they were within my budget, I would get the Swarovski, a bit more aperture and probably much better optics. Just my opinion. Regards, Bill

    forgive the error, the Swarovski model is 8x30 and not 8x39 ..
    Thank you

    They will still probably pass a bit more light due to superior optics. Try them out if you can. Bill

    Hello Tico,

    since I have the 7x50 and 15x60 Docter Porro binoculars, I have parted with some other ones in my collection.
    These Docters offer in 50mm and 60mm apertures the most light and highest contrast I have ever seen,
    leaving behind the best and the most advanced roof prism binoculars from Leica, Swarovski and Zeiss.

    Clear skies,

    JG

    If you have to have the small 8x30 format, it really does limit choices. The only glass in that size that I have personally used is the Nikon monarch. Really good glass for the money but the shortcoming of the small glass is light gathering. My advice on binocs is to always try before you buy or buy where you can return. Twice now I have got binocs that looked great on paper only to totally disappoint when I tried them in person. I was looking for binocs recently in the under $300 range. I had my mind made up on some Nikons. Went and tried them in person and was really disappointed. Good but not great clarity focusing was not very precise. Ended up getting the leupold BX2 alpines. Lighter but better clarity especially in low light which is their main selling point. I own many pieces of Nikon glass but this is my first ever leupold. I have to say I really like them. Took them to Colorado recently on vacation in the mountains and worked great both wildlife watching and stargazing.

    I have the Swarovski's. The link that John provided is pretty much what I have observed as well. The "prism leak" that is spoken of in the review is the only annoying thing about them: it manifests as a bit of glare in the image when a bright object is nearby (like the sun(!) or the moon or a streetlight at night. Otherwise they are amazingly sharp to around 70% of the field, and have a light transmission that is superior to anything (96%) I have ever read about or seen. This compensates somewhat for their small size, and I find them very nice as astronomy binos: super sharp in the centre and very high contrast. I have seen Barnard's loop in Orion quite easily with them, and more nebulosity around the SMC and LMC that I have seen in any other binoculars.

    Because they are waterproof the focusing wheel is a bit tight at first, but I found it became easier to turn after a while, and is not an issue.

    This review: greatestbinoculars: Swarovski Habicht 8x30 W binoculars review also pretty much reflects my experience with them.

    All the best,

    Dean

    Thanks for all the opinions.
    Dean, really if you saw the Barnard loop in Orion, that says a lot about this Swarovski 8x30 model, since according to I had always read in astronomy magazines this object was almost exclusively photographic .., in fact I have tried it with several binoculars, including a Vixen 12X80 and nothing at all ...
    I like, after dinner, to go out to the surroundings of where I live, that there is not too much light pollution, and to look at the night sky, when there is Luna I love to observe it and when there is no ground I go through the sky with binoculars, but the ones I have are big and heavy, the image trembles and I do not like to be loaded with tripod ... this is why I want to get some small and handy binocular with great contrast and sharpness.
    Then, and in your personal opinion, these Swarovski 8x30 would be fully recommended for this type of astronomical observation? that is, wide views of the sky, not for individual objects (for this I already have a good telescope and some larger binocular with more magnification) but rather to contemplate celestial landscapes and stellar fields on the Milky Way during the summer, and if really they have great contrast and luminosity maybe I am lucky enough to see the Barnard loop in winter (I live in the Northern Hemisphere) or the North American nebula in the swan or the dark nebulae in Altair in the eagle during the summer ... ooooh !! It would be fantastic, do not you think?
    thank you.
    Tico.
