    Bushnell Rangemaster: Vintage Binocular vs. Modern Birds

    Many thanks to Henry for his analysis of the Fuji 7x35 monocular. For the relatively few persons out in BF land interested in the Rangemasters, (my assumption), I need to caution them that one cannot analogize from his examination of one sample to the CF Fuji 7x35, particularly the silver ring...

    Bushnell Rangemaster: Vintage Binocular vs. Modern Birds

    Henry - My technical knowledge of optics is limited, but I believe the Booster is a Galilean hybrid. The image coming out of the end is straight up. Interestingly, when I place my little Zeiss 3x behind the Booster (there is a round groove which helps center it), it becomes an excellent 7.5x...

    Bushnell Rangemaster: Vintage Binocular vs. Modern Birds

    Henry - The Fuji(s) I have just state, "coated optics." Regarding the order of the lens, I'm sorry but I didn't mark or write that down. I should have. And I should have saved the broken lens, but I didn't. This I do remember, the exterior part of the lens was flat, and the back side was...

    Bushnell Rangemaster: Vintage Binocular vs. Modern Birds

    Another piece of information to give you some perspective. When I damaged the top lens of one of the oculars of the IF Fuji, I sent the whole package to Cory to see if he had a lens in his collection which would fit. Meanwhile the Fuji monocular arrived, and although the housing was in rough...

    Bushnell Rangemaster: Vintage Binocular vs. Modern Birds

    Steve & Henry - Guess I'll add to the confusion. My first Fuji FPO was an IF binocular which exposed the serrated bottom once the eye cup was removed - the kind Steve has. One of the eyepieces showed the beginning of a lens separation of a doublet on the edges, the kind when balsam cement is...

    Bushnell Rangemaster: Vintage Binocular vs. Modern Birds

    An O ring can be used on the Fuji to help hold down the loose piece. Or a flat rubber washer(s) can accomplish the same thing. My suggestions are only an improvisation for eye glass wearers who remove the eye cups to get more FOV. Fuji made shallow eye cups for their binoculars. I have a pair...

    Bushnell Rangemaster: Vintage Binocular vs. Modern Birds

    Steve - In comment #47 I recommended how to create a mar free surface for eye glass wearers. I assumed (wrongly) that you would find the same surface as the FPO with silver rings. The Silver Ring FPO, which has the same optics as yours, has a ring nut that screws down flush with the serrated...

    Bushnell Rangemaster: Vintage Binocular vs. Modern Birds

    Just my opinion(s). When ever I read comments from some of the learned folks on this web site, who are so mesmerized by all the light transmission data and highly magnified resolution tests for certain binoculars, and when their comments strongly suggest they simply haven't looked through the...

    Bushnell Rangemaster: Vintage Binocular vs. Modern Birds

    Good. Now there is a simple strategy to allow the dedicated eye glass wearer or person using sunglasses to get close to the full FOV of yoiur FPO. Get one of those plastic templates for drawing circles - normally have a variety of diameters. Then get a piece of 3-M sticky back tape in the...

    Bushnell Rangemaster: Vintage Binocular vs. Modern Birds

    Steve- good summary of your findings. I have a question for you. When you unscrew the eye cups from the FPO, what is surface of each ocular like? John

    Well Steve, did I give you a bum steer? John

    Bushnell Rangemaster: Vintage Binocular vs. Modern Birds

    Thanks Steve - first about your case. With a little bit of shoe polish and buffing, it will look first class. The strap is still intact, meaning the leather is not dried out. Avoid using leather softing dressing. The Japanese used vegitable tanned leather, which is the best treatment for...

    Steve - Your Fuji looks pristine. Did it come with a case? John

    Bushnell Rangemaster: Vintage Binocular vs. Modern Birds

    Enjoyed your review, Steve. I couldn't tell whether you have a Fuji now or are waiting to purchase one? When I say Fuji, I refer to the silver ring model, the one Fan Tao prefers. IMO it is the best of all of them. The Tamron you have is excellent, but suffering from short ER, and as you...
