    Observations inside two Abbe Koenig Zeiss models

    Hello! I am the very happy owner of one pair of 10x42 Victory FL and one pair of 7x42 Dialyt T*P*. However, one day I decided to look down the tubes of my FL from the objective side. First I was shining a strong LED lamp in through the front lens, and it looked as nice and clean as one should...

    Is it possible to fix the play in a focus wheel?

    I have a couple of mm play in the focus wheel on my binos when turning it. Is there a common reason for play in focus wheels? Is it something that can be fixed by tightening some screw, or is it beyond home fixing? I notice no effect with temperature on the play. These binoculars are roof...

    Sweet spot peculiarities; I can´t get the center as sharp as the periphery

    Hello! I have noticed when looking through my binoculars, and I have a bunch, that the sweet spot, to my view at least, is, to begin with, not symmetrical around the optical axis; it is much wider horizontally than vertically. But then is the other oddity; I can not get the center as sharp as I...

    Want to upgrade from Zeiss Conquest 8x32 HD

    Hello! I own a pair of Conquest 8x32 HD. There is much good to say about this model. It has fantastic image presentation, wide FoV, bright image, solid mechanics etc etc. However, I have come to be increasingly annoyed with a some features that may be details to some, but that apparently means a...

    Jaxy WDM03 12x56ED A high power budget alternative

    I was trying to post this text as a product review, but I did not manage. I try to add it as a binocular forum post instead. In any case, I just want to make you aware of what value for money there is to be found if one chose to go directly to the (in most cases Chinese) OEM (Original equipment...

    is there technology transfer from OEM brand to producer?

    Many binocular brands, even relatively high-end ones, are having their products produced in the same main factory, usually in China. This factory offers various levels of quality and the binocular brand can decide which level to choose for a certain model and also make suggestions for the...

    Does anyone know how to tighten the central hinge on a pair of Bushnell Ultra HD

    Hello! I have a pair of Bushnell Ultra HD 10x36 that I like very much optically. Mechanically they have been a little weak, but in their defense I must say that they are very small and lightweight. After some years use the central hinge has now got annoyingly loose. Is there some way of tighten...

    Need advice on upper mid-level 8x32s, e.g. Rainier or Conquest hd

    I am looking for an 8x30-32 with good quality optics, especially good field of view in combination with all the other criteria (low CA, sharp, bright, contrast, edge sharpness etc). I have had the chance to compare Zeiss Conquest HD 8x32 with a few both cheaper and more expensive binos. I like...

    Home made adapter tip

    Hi! I have made adapters for two of my compact cameras (see attached photo). One is a Samsung NV40 and the other a Samsung EX1. The adapters are attached (easily detachable) to the cameras and slide over the eyepiece of the spotting scope (in my case a Brunton Eterna 80ED) all the way down until...

    Is there any benefit from down-stepping from highest to lower resolution?

    Most digital cameras offer the possibility to choose various resolutions. For instance, my camera is a 10Megapixel camera but offers lower levels such as 7Mp, 3Mp. In articles about the "Megapixel myth" we can read that a camera with, for instance 6Mp not necessarily makes less sharp images than...

    Spain red and yellow winged pigeon?

    I was birding at the Tablas de Daimiel last weekend and spotted the attached bird. Size and shape as a pigeon, but a coloring I have never seen before on either wild or domesticated pigeons. I am not sure it even is a pigeon, but it has too short and rounded wings to be a pratincole, which was...
