    Need to adjust diopter when switching focus distance?

    In my book you need not bother with subtle glass issues when the focus mechanism is so sloppy you see with the naked eye the parts rock when reversing. Not until that is fixed may you question other factors Cheers zp*

    Need to adjust diopter when switching focus distance?

    Hi for a close view of the technical issue behind this problem on cheap roofs have a look at : Diopter focus inconsistency (Ed x) if you have an expensive roof with this kind of focus slop get it fixed, don't let the manufacturer get away with it. cheers, zp*

    Reskinning an old porro

    Done this a couple times already Most difficult is the choice of the skin. Leather needs to be thin enough not to protrude above the end plates but stiff enough it doesn't stretch much, otherwise it will wrinkle over time. Leatherette is easier but need to have enough texture ("pebble finish")...

    Appreciate Binocular Advice for Nonprofit Outdoor & Nature Program

    if budget really is an issue I'd go for naked-eye nature observing. nothing worse than $50 binoculars where image is blurry and no field of view $100 range, out of 5 pairs only one you can keep, the rest is so badly out of alignment people new to this will assume bins are not for them don't let...

    Checking Collimation

    Hi most often the inner lens is attached to the inner excentric, i.e. the lens will rotate with the inner ring. The outer eccentric ring shall rotate freely around the inner ring and inside the objective tube. if the eccentrics are loose, sticking, oval, pitted, dirty etc, you'll struggle with...

    Checking Collimation

    Hi Did you try it? Show us the results! Maybe you can use a far away target looking outside the window as a substitute for a complicated device? cheers zp*

    Habicht with sticky rubber

    Yes you are correct In this case of sticky rubber I'm sure they can't afford to have many binoculars go sticky over five years, and in the XXIst century this problem is not unfixable (hey, most leatherette never fails). So remains the possibility they have low incident count and then chances are...

    Habicht with sticky rubber

    Online available camera leatherette has never failed me (been using it for 15+ years to renew 50+ years old binoculars where leatherette was crumbling, never had one go sticky yet) Swaro leatherette is most likely to last forever. Swaro as an industrial company works like this : warranty returns...

    Habicht with sticky rubber

    Hi It can happen on rubber-like material when the chemistry of the mix was not correct. Unfortunately it only happens after a few years so it ain't easy for the manufacturer's quality control to detect. This happened on a whole batch of Canon IS binoculars a few years back. Your options are as...

    Pre-nitrogen Habichts -- prices?

    The purple coating (transmax) which gives a yellow cast to the image makes this model a late 70s or early 80s one. The condition is unusually pristine therefore maybe worth such a premium to a collector. Cheers, zp*

    Pre-nitrogen Habichts -- prices?

    Hi You are talking pre-1984 binoculars. They are no match for current production Habicht, Swaro has improved quality of its optical components and coating technology a lot at the end of the XXth century. If you are looking for the best viewing experience, fork out the ~1000 and get a current...

    Advice on Habicht please.

    Had both EL and Habicht, sold the EL and kept the Habicht. 7x and 10x Habichts are same mass, same field (114m for 7x and 108m for 10x), and if you have to choose 10x is more magnification when 7x is less shake and more purity in low light condition. The 10x is more an all-around use whereas the...

    Repairing an older pair of Frontier EDs

    Make sure to use silicone based lubricant and NOT lithium grease as used for vehicle lubrication as it hardens over time to the point of completely seizing the focuser. Axle grease is NOT fine for binoculars. Cheers zp*
