Question: Many buys lens caps and uv filters with these. Can these be used with the Binoculars?  Or is it just another purchase?
Document: Worst case scenario, I replace the UV filter if damage occurs, which is not a bad tradeoff vs. constantly taking the objective lens caps on/off. Both the UV filters and the lens hoods I used are from B+W, but there is many less expensive brands to choose from. The lens hoods also do a good job of reducing lens flare, as the objective lenses are very vulnerable to stray light as they are not sufficiently recessed.
In a lifetime (I'm 84) of owning high-end binoculars and cameras, these are the best all purpose binoculars I ever used. The IS feature is mind-blowing. Early reviews criticized the protective lens covers. Canon may have improved them. The objective lens caps were just a little difficult to snap into place until I installed Hoya HD UV filters. With the high-end Hoya filters in place, the end caps snap in effortlessly.
That's the main reason I went with these. However, the lens cap solution for the binoculars is pitiful. The rear caps are not too bad but the front caps just don't stay on. I thought I'd scratched my expensive front elements the first day I used them. I had them around my neck and then we tacked. During the tack the front caps just fell off and I bumped the element on a plastic part in the cockpit. It appeared to have made a scratch.
So, I dodged a bullet. I've now put 52mm daylight filters over both front elements to protect the optics and am using regular lens caps. Only now I have these two loose lens caps that I have to keep up with when using the binoculars. It's not such a bad trade-off but Canon could easily have come up with a better lens cap design, especially for a product with and MSRP of almost $2000.
Strangely, I did not notice much of a difference with the extra 8mm of aperture. I think the better IS in the 10x42 cancelled out this advantage.Miscellaneous:Everyone has complained about the objective lens caps. I bought two B+W 52mm clear filters (007M) as added protection and the supplied caps click and stay on these filters much better than without them. The added plus is that it's easier to clean the binoculars. In case you mess up, you haven't scratched the costly lenses.
I rate the package of binoculars, high end Hoya UV filters and B+W lens shades a solid 5+.ADDENDUM:I got two Zeiko 52mm snap-in objective lens caps. They are superior to the original canon caps and for $8.50 from amazon are a no-brainer.These magnificent binocs continue to amaze me. I use them daily for bird watching as spring takes over the southern Rockies here in Santa Fe. FWIW, I'm still on the original batteries.
I have used these binoculars for over three years, and have used them for viewing the night sky as an amateur astronomer.These glasses are truly wonderful, and are a dream to use. The optics are great, and I have not seen the difficulties noted by another review. Reliability, weight, and maintenance are fine, and have presented no problems.The true/real field of view is a very nice 6.5 degrees, and the weight is 37 ounces.
These binoculars are truly amazing in image quality. The stabilization is remarkable also. I have been sailing for 30 years and have had many sets of binoculars but never any that were stabilized. I used to have to float my elbows and be as steady as humanly possible to read anything that didn't have huge letter while on the water. Now I can read small boat names on the transom from any distance.I do have one negative comment.
It is heavy, but the image is fine, especially when stabilization is on. Some reviewers complained that the optical lens caps didn't stay on. It's true, but if you screw the recommended 52mm UV filters on...mine are made by Tiffen...the caps remain in place perfectly.
IMHO, the sellers should be advising us customers that the design of the Canon lens caps is defective in regard to the purpose for which they are intended, and that it is advisable to buy protective filters and snap-on caps. Except for the lens cap problem, these binocs would clearly rate 5 stars.
Answer: Yes, the filters can be used on the binoculars and I recommend them to protect that nice expensive glass you are buying. I've been a commercial photographer for 30 years and I'm an industrial designer so I do have some understanding and experience with these kinds of things. Canon's lens cap design is laughable and I'm surprised their designers did such a poor job designing them. With the camera lens filter you can use camera lens caps which works well. If I recall the filters were 52mm but please verify that on your own. I could be mistaken. I got two skylight filters for really cheap and for the caps I got the kind with a tether for about $2.00 here on Amazon. You don't need expensive filters because you are just looking through them and not grabbing a photo. As photographers we always hate putting more and more glass between our subject and our digital sensor as each piece degrades the image a little bit more. But since you are just looking through, the cheapest filter you can find will be perfect and you'll never notice anything. The cheap ones will protect just as well as the expensive ones.I put a 1" piece of the hook part of the Velcro on the lens cap and two fuzzy pieces of Velcro on the body of the binoculars under the front end. I take the lens caps off and just stick them underneath. They are out of the way and don't flap around in the wind. If you leave the lens caps just dangling they swing and  bang into each other like crazy in the wind and it's annoying. You may have to fiddle with the tether a bit to tie a loop that fits around the threads of the skylight filter so you can screw the filter down on top of the loop in the tether. That will hold the cap to the binoculars. The Velcro works perfectly and after a year now it's still working great.I hope this helps,Rob
