Objective Lens Covers for the 10x42 IS-L?

Does anybody know where you can get the objective lens covers for the Canon 10x42 IS-L? I bought a pair and they were missing. Either the plastic Canon OEM cover or Canon snap-on covers. Thanks.

I suggest calling Canon USA Support to see what they will do for you, but I would not have Zeiss or Swaro expectations. If you have already tried that, I would be curious to know what they told you.

The 10X42 has threaded filter objective ends so that gives you a couple of other options to consider. One is to thread on a couple of UV lens filters. That can get a little pricey depending on the quality of the filter. A second option is to get a couple of 52 mm lens hoods for some additional protection. You can get them for not a lot of money on Amazon or eBay. The binocular will still fit in the Canon case and they also look cool!

I went the UV/Haze filter route, along with camera lens covers made by Sigma. OK - so not as cool-looking as Bruce's system, but it works well, and the lens covers stay attached better than the OEM Canon covers.

I too went the UV filter route and found it unsatisfactory.
Under cold and wet conditions, condensation will build up on the inside of the filter.
The lens hoods seem like a better solution to me, thank you, BruceH, for the link.
I will order a pair.
Do note the front glass on the 10x42ISL is a flat glass rather than a lens, so a filter is somewhat redundant.

Also there are slight ghost images from bright light sources at night on the 10x42 and 18x50 Canons.
I think due to the front optical windows.
But both are still excellent regarding ghosting or flare, glare.
Canon have done a good job despite the flat glass.
Adding filters may not be a good idea unless specialised nebula or light pollution rejection filters.

With astro telescopes tilting filters or optical windows 1 degree removes ghost images while retaining full optical quality, but this does not work with wider field binoculars I think.

For anyone contemplating the purchase of a 10x42 Canon -- do note that the reason for a filter is not to have a 2nd layer of glass (which would indeed be redundant), but is instead to have a first layer of protection. For those who do not have a 10x42L -- the front glass is almost to the edge of the bino's body, so the body does not afford a great amount of protection of the leading glass element such as you would see in other binos such as a Toric. I can guarantee anyone that it will be tremendously simpler, quicker and cheaper to replace a damaged filter than it would be to replace a damaged front glass. I would put a high-quality filter on the front of all my high-quality binos, if I could.

2nd reason is that a UV/Haze filter will give a very slight amount of increased contrast in bright/hazy conditions. Yes, the difference is slight, but it is there. YMMV, depending on how good is your eyesight.

So very true because by adding the filter you are adding an optical layer that does not benefit from the gas purged inner fog proofing of the binocular. Lens hoods would be a better idea. Mine had polarizing filters on it which really reduced the light transmission so I removed them with much difficulty because the outer ring turns and it is very difficult to a grip. I finally watched a Youtube video that said to put a thick rubber band around the front edge of the filter to give more grip when you unscrew them and damn if it didn't work. Thank god for Youtube.
