Kalimar was brand used by Ashai that generally sold below their Pentax line. Nevertheless, I'd eBay them (with full disclosure). The repair of binoculars is complex and requires specialized equipment. Few if any repair facilities are equipped for this work. I doubt the binoculars are worth the expense is you could someone to do the work.

Blurry binoculars


Unfortunately, the reason for the blurryness is that the binoculars will not focus. Either the lenses have become dislodged, or something is obstructing the full motion of the eyepiece lenses.

I tried to fix a pair of binoculars that had the same problem and finally gave up.

You will probably have to get them professionally repaired. Be sure to get an estimate first, though, because the repair cost may be more than the binoculars are worth, depending on how much you paid.

Wish I had better news!

Good luck!

The eyepiece lenses have something on the inside. Can they be removed for cleaning?


  1. Carefully clean your binoculars by firstly removing any dirt or dust from the main body and straps using a soft microfibre cloth. Avoid the lenses at this point using any form of cloth on the lenses before removing all dirt and dust particles first could destroy them.
  1. Gently remove all traces of grit, dirt or dust particles from the lenses using a soft lens brush or canned air specifically designed for the purpose.
  1. Waterproof binoculars can be rinsed gently under a tap but be sure to use on lightly running water, avoid high pressure water as it could damage your binoculars.
  1. Gently remove any remaining marks using lens cleaning tools such as a lens pen or lens cleaning fluid and lens tissue. Do not be tempted to use kitchen towel or anything else lying around that is slightly rough and may scratch the surface of the lens, only use a lens pen, lens tissue or a lens cloth. Gently wipe the lens using a circular motion working from the centre of the lens to the outer edge. NEVER apply lens cleaning fluid directly onto the glass (always apply to the cloth) and always ensure that the lens cleaning fluid you are using is recommended for the type of lens coatings that have been applied to your binoculars (Do not use general household glass cleaning products or products designed to clean computer screens or glasses. Such products could destroy the lens coatings of your binoculars if used).

The entire diopter setting eyepiece was off.I separated the eye cup from the rest of the diopter setting eyepiece, and aligned the channel guides on the lens piece to slide it into place. Then holding it in place, taking care not to gum up the lens, I experimented with how to screw in the retainer ring so that its white dot registered correctly. Finally reattach the eye cup and focus. It's like new!

Mildew on inside of Sans & Streiffe binoculars


Once mildew or fungal growth gets into a binoculars you have a major problem. Fungus 'eats' into the glass. Once this has happened the lens or prism needs to be replaced. There have been a number of solutions over the years but non has been able to fix the problem. Even if the fungus is gone there will be an effect on the clarity of vision. Binocular glass is made to be as clear as possible. Sans and Streiff made mediocre binoculars in the early years using BK7 glass with the last ones being quite good in the lower end of the market using BAK4.

Replacement parts are not readily available and the cost would exceed the worth of the unit. Unless is it has some personal significance it is not worth fixing.

I just got an old set of kalimar Model K7070 Binoculars ( 7X-15X35)from my father. They seem to have some type of water drop marks in the left lens. Are these worth trying to repair. I do not know what he...


The water drop marks you are seeing may be seperation of the lens coating. Most binoculars after WW2 have some form of anti-relective coating on the lens. This is applied to the glass surfaces in varying degress by various manufacturers. Its intended purpose is to reduce the amount of light that is reflected off the glass so that the image you see is brighter. Your windows at home that aren't covered actually don;t allow all of the light to come through!
What they all have in common is that the coating is applied onto the glass. Over time like anything that is stuck on or painted it can begin to peel off.
You could try asking a repair place if they caqn replace the lens but most likely they would need to change both so that they have the same coating. The binoculars are worth more for sentimental value than the cost of repair as a similar replacement set would cost as much. Zoom binoculars are not known for their optical quality. Often this 'watermark' effect doesn not interfere with the view. If your sentiments say fix them regardless do so. If not hold onto them as a keep sake.

How to put lens back together on a Bushnell Permafocus 17-5012. Lens had fallen in and now I have it appart but do not know what goes first,and so on.


Hi,

I presume you have this fixed by now but if not I'd recommend getting it back to Bushnell for repair(is it still in warranty?)
The Permafocus binoculars need specific callibration and the risk of dust or moisture getting in while open is not worth the hassle..

No zoom function on a kalimar power zoom scope,


larry389's so-called solution is not a solution... just an opinion to which each individual is entitled... even when not correct! I've used a Zeika Opt. Co. Power Zoom Binocular No.25361 for over 25 years since inheriting them from my father who purchased them in early 1970. To say the least, treated carefully and with respect for the delicate instrument that they are, they've been wonderful and still work perfectly fine. Perhaps Larry's experience is based upon handling them like junk and, therefore, reaping what he has sewn.
