    Keep my new Victory 8x32 FL or get something less expensive?

    The British Red Deer and the North American Elk would seem to be the same species, according to the experience of a North American wildlife park (whose reference I have lost). The two subspecies interbred enthusiastically, resulting in fertile offspring. So the names can be summarized as what...

    Zeiss Dialyt 7x42 B/GA Classic – focusing direction?

    Thank you, Arthur; thank you, Alexis. You are quite right, of course, that I typed Zeiss BN for Leica BN -- twice :eek!: -- while my brain was on another planet. Sorry about that. There is a coda to my tale: the already emerging cult of the 7x42 B/GA Classic as it was 15 years ago. I went to...

    Zeiss Dialyt 7x42 B/GA Classic – focusing direction?

    If the OP will permit it, I'd like to ask a slightly different, but closely related, question about the 7x42 B/GA Classics. Why is it that, twenty years on, these bins inspire so much more affection than the other top-flight binoculars of the late 1990s? In 2002, at a photographic trade show...

    Keep my new Victory 8x32 FL or get something less expensive?

    Hej Gunnar! My short answer: * if you wear glasses, keep the Zeiss FLs ... you won't find anything better; * if you don't wear glasses, consider the Leica HD+ Ultravids ... they're as good and slightly smaller. My longer answer: I've been looking at 8x32s recently: I am on an on-off quest...

    Leica Trinovid HD 8x32

    Thank you once again, Lee. That was exactly what I hoped to learn. It all contributes to my on-off quest for the perfect bird-and-butterfly bins ... which is hindered on the one hand by dreams of a four-inch refractor, and on the other by the Pussycat's belief that I already have enough...

    Leica Trinovid HD 8x32

    Thanks for the review, Lee. When you were using the Trinovid, did you notice how much turning it took to change the focus from close up to infinity? John

    Zeiss 15x56 Conquest?

    Hello everyone, Are the Swarovskis in these tests the current models? I'm somewhat confused. Roger Vine (scopeviews) makes it clear that he tested the HD model of the SLC 15x56 earlier this year. But the current model on Swarovski's website doesn't have this HD label any more. Does this...

    Replacing 8x42 T* FL with lighter weight model

    Hi Helen, Have you seen that Focus Optics, in the countryside north-west of Coventry and so not that long a drive from Oxfordshire, has a secondhand pair of Zeiss 8x32 FLs in stock? http://www.focusoptics.eu/webshop/used-binoculars/zeiss-victory-fl-8x32-simon-king-edition-37/ John

    Zeiss-ness: 60 hours with the Oberkochen 8x30

    Thank you for that, Arthur. You have carried out more experimentation than I. In the days before I could afford 'B' binoculars -- back when the label "alpha" was pronounced "Leitz 'n' Zeiss" -- I did not realize that binoculars could provide sharp images without vignetting. :eek!: Once 'B'...

    Zeiss-ness: 60 hours with the Oberkochen 8x30

    Hi Patudo, Thank you for this essay. It contains an awful lot of information; I've read all three parts closely, and enjoyed doing so. But ... ... my sensibilities as a technogeek and amateur pedant jumped at this sentence. It sounds right, but it isn't, and I don't think it should be...

    MHG - Beginning or end

    Hello again, Moog, Butterflies! Fascinating creatures. A couple of years ago, I set out on a quest for a pair of top-flight x42 bins suitable for watching both birds and butterflies. This ended up at an optics day at Titchfield Haven in Hampshire spending some quality time with Swarovision...

    MHG - Beginning or end

    Hi Moog, Reading about your quest, as you apply serious thought and experimentation to finding the binoculars that best suit you, has been fascinating. At the risk adding unnecessary detail to your pile of information, I'd like to mention one datum which I came across only recently, and which...

    A thread to discuss Alphas where all opinions are considered equal.

    Hello Lee, Hello everyone, Sorry to be six months late, but it is important to my bank balance that I follow this forum only occasionally. Two years ago, you all helped me believe that I needed a pair of grey 8x42 Victory SFs -- a purchase I have never regretted -- and I don't need to learn...

    Large partial solar eclipse March 20

    If he is a keen user of neutral-density filters, Binastro, he may have better filters than you realize. Many landscape photographers nowadays use Black Glass filters, which allow only one-thousandth of the light to pass. In photography-speak, these are known as 10-stop filters (log to base 2)...

    New Leica HD Ultravid PLUS

    Hello Hermann, Leica UK is the same. Until very recently, it had the non-plus 50mm HD models; both websites still list downloads for the non-plus models. I suspect that the websites are in transition; that the webmasters are removing the details of the older models to make space for the newer...

    Binocular shop London

    The London Camera Exchange chain has a store in The Strand: http://www.lcegroup.co.uk/Branch/?Branch=London+%28Strand%29 This advertises that it has "a large range of binoculars and telescopes for you to look through and try". The chain as a whole certainly stocks Zeiss glasses, but you'd...

    Is 8x32 or 8x42 the best Birding format?

    Hello again Dennis, A second, different, observation based on your original post. Is it reasonable to infer from Zeiss's website and its recent product-range actions, that it sees the Victory HTs as its premium hunters' glasses and the Victory SFs as its premium birding glasses ? ... though of...

    Is 8x32 or 8x42 the best Birding format?

    "8x32 or 8x42 ?" is two questions not one Hello Dennis, I would like to make the case that the vote you suggest is too simple ... that your original post in fact asks TWO questions, not one: If you could have only one pair of glasses for birding, would you choose 8x32 or 8x42? If you had...

    Close-focusing alpha field glasses

    "Optimised Focusing System" from Nikon That day may be coming closer. Nikon has sent me a hard copy of its latest EDG catalogue -- which is available online at http://www.nikon.com/products/sportoptics/lineup/dl/catalogue/EDG_20p.pdf -- in which, on page 13, "Nonlinear movements of...

    Close-focusing alpha field glasses

    Thank you. I hadn't realized I would need to take alignment into account (another thing of many). I haven't noticed any problems using the original-EL 8.5x42 Swarovskis at about 2.5 metres (about 8 feet), but I may be favouring one eye without realizing it. Is the Leica you mention the...

    To Infinity, and Beyond

    Thank you everyone. Thank you for confirming that my optical ramblings were valid ... even if they are of no practical benefit. I wasn't sure: I have no training in optics beyond sixth form (high school) but have learnt to apply these principles to photography. Light is still light (even if...

    To Infinity, and Beyond

    Good afternoon everyone, Can binoculars focus closer if I wear reading glasses? Let me explain. Many binoculars focus beyond infinity if a person with “normal” vision racks them right in. This, I understand, is so that folk with short sight, who have no astigmatism and a relatively moderate...

    Why couldn't a catadioptric or newtonian optical system be used in binoculars?

    Psychiatrically off-topic Once upon a time, the Pussycat and I went to live in Denmark for a year, so we looked for the cheapest one-way flights from London to Copenhagen. It turned out this involved changing at JFK Airport, New York and Reykjavík Airport, Iceland. John

    Close-focusing alpha field glasses

    Canon 10x30 IS outperforms standard 10x50 Thank you. It seems I have wildly underestimated etudiant's suggestion of the Canon 10x30 IS. Sorry about that, everyone. In particular, sorry, etudiant. When I were a lad, the standard advice to a juvenile astronomer (me) was to start with field...
