    Dead forum

    Although never very active, it seems this forum died when it was moved to General Outdoor Equipment from the old forum structure that binned it with other equipment including optics. I rather suspect that all the topics in the General Outdoor Equipment section get less attention than they might...

    Zeiss classic rainguard discontinued!!!

    What happened? Did I miss the announcement? This makes me sad. This is a product (#529205) that should have stayed in the Zeiss catalog until the end of time. I just noticed while responding to a question in a different thread. https://www.birdforum.net/showthread.php?p=4051775#post4051775 --AP

    Gitzo "birdwatching" heads discontinued !

    I just noticed that the Gitzo "birdwatching" heads (GH1720QR and GH2720QR) appear to have been discontinued! They are no longer carried by B&H, Adorama, and some other vendors that I checked. I am a great fan of the GH1720 as the best ultralight and ultra-fast-to-operate scope head, and I'm sad...

    Adapt Manfrotto/Gitzo/Sirui clamp to accept Arca-Swiss plates

    I recently learned that the Desmond DGZA-1 is no longer available. It is my favorite adapter for using Arca plates in heads that are meant for sliding plates of the Gitzo type C/Manfrotto/Sirui variety. The similar but much more expensive Gitzo GS5160CDT adapter is likewise gone from the market...

    Kowa 773 vs. Meopta S2

    These cost about the same, the Kowa tending to be somewhat cheaper. Any informed opinions? --AP

    Contemplating ~80mm scope w/WA zoom for digiscoping

    I'm in the early stages of considering purchasing a large scope for biological survey work that would often involve digiscoping for documentation, to be used mainly by my graduate students for our research. At the same time, I would be purchasing a camera, tripod, tripod head, and digiscoping...

    Update on Bushnell 8x42 Legend Ultra HD focus

    This is a follow-up on the unit I purchased for a friend in December 2011 and described in this review: http://www.birdforum.net/showthread.php?p=2319854#post2319854 Well, after 6 years of regular use, it has now broken. The problem? The focus now decouples a little at its limits, so the left...

    Holding the Swarovski 8.5x42 EL Swarovision

    This is a post that I've been meaning to get around to writing ever since the Zeiss 8x42 SF was released. The world hasn't been crying out for this post, but here it is. In comparing the Zeiss 8x42 SF to the Swarovski 8.5x42 EL Swarovision, one of the supposed advantages of the SF is more...

    Feel Nikon "Recollections" website

    I usually stay away from Nikon's many variously redundant, incomplete, unstable yet rarely up to date, and labyrinthine websites, but I was just trying to look up some Nikon history (the dedicated web page, both old and new versions seems to be gone now) and I stumbled into the "Feel Nikon"...

    Bins in movies: Moonrise Kingdom

    I know there have been threads in the past on binoculars in film/TV, but I don't think anyone has mentioned the movie Moonrise Kingdom here. It's been getting good reviews all summer, so when it finally came to the $2 theater near where I live the other day, I went to see it. I don't think I've...

    seeking info on Hazel Grouse plumage color variation

    This is a question for birders with first-hand experience with Hazel Grouse. Some book sources claim that Hazel Grouse have both clinal variation in coloration and color phases akin to those seen in Ruffed Grouse, while others suggest the variation is only clinal within the species as a whole or...

    Nikon ED50 tripod socket design & excellent Nikon USA customer service

    Although the topic hasn't come up recently, there has been much discussion in the past about the tripod mounting foot of the ED50 Fieldscope and problems with its durability, particularly with the metal threading (helicoil) unwinding from the otherwise plastic foot. I've posted to some of these...

    cheap Nikon Fieldscope eyepieces

    Adorama has drastically cut prices for most Nikon Fieldscope eyepieces. Like drastically. I presume this is related to the impending release of the new Fieldscopes. If you're a committed user of your Fieldscope and always wanted another eyepiece (bought new), now's the time. --AP

    best price on 82mm ED?

    I have a friend who is interested in the 82 mm ED with 25-75x zoom. Going rate at most places seems to be ~1300. That's about $300 more than the best deals that I read/heard about a couple months ago. Anyone know of a place to check for a low price at the current time? --AP

    Better View Desired website changes

    In response to a request for info about the Swift Audubon 827 roof in the Swift subforum, I went to the BVD website to get the link to Steve Ingraham's review in the June 1996 issue but found that the website has been reorganized (and is now sponsored by Christophers/Astronomics). I searched...

    Bushnell Discoverer roofs to be discontinued

    I dropped by the Bushnell headquarters and repair lab/factory outlet the other day and noticed that they were selling the 7x, 8x and 10x42 Discoverer roofs for something like $280, which is less than what these have been selling for recently. Since prices in the store are generally closer to...

    Awesome deal on B&L 7x42 Discoverer equivalent

    Anyone who is a fan of the now discontinued Bausch & Lomb 7x42 Discoverer will be interested to know that Christophers (Astronomics) is running a close-out sale on the Meade Montana, which is its equivalent (same manufacturer under the label). This is a phase-corrected, silver coated...

    sweet spots, chromatic abberations, and eye position

    I noticed something recently that really surprised me, and I wonder if it relates in some way to the discrepancies between different observers' reports of edge sharpness in a given binocular model. For the record, I am an eyeglasses wearer and a person who easily notices chromatic abberations...
