    Sensei CK-L reviews

    Cap Keeper Lens Cap Holder is rated 4.4 out of 5 by 416.
    Rated 3 out of 5 by from Not great for me I like the idea of a tether on my lens cap so I can just pop it off and let it go and for protection against loss if the cap gets knocked off. However, the tether on this one is so short that I find it hard to use it. If I locate the elastic band way out, just behind the lens filter, then the elastic band often pops off. But, the tether is not long enough to locate the elastic band way back on the lens, close to the camera where it doesn't interfere with focus or zoom rings. I'll still use it because it beats having to deal with lens caps falling off or needing to be stashed every time I take a picture but it is not as carefree as I had hoped.

    Rated 3 out of 5 by from Sensei Lens cap keeper Attaches easily and won't come off (but you can purposely remove it with a bit of energy). I removed mine because it was difficut to use with a lens hood attached. I found that I can squish it between the mounts, but I didn't like doing that and it resulted in the lens cord being too short to use. I have had one of these for years on another camera (without a hood) and have had no problems at all with it. Guess I'll have to go back to using my pocket to hold my cap when I remove it. This keeper does what it is supposed to do, but bigger zoom lenses and hoods make it impractical. Fine for all other uses.

    Rated 4 out of 5 by from Handy gadget I have used these for years to help keep me from losing lens caps when I am working in the field. It is an inexpensive solution to the problem of helping protect the lens. The only problem I have with them is that sometimes, when I am carrying my camera in my hand and walking, the cord connecting the lens and the lens cap will snag on a bush or something and on one occasion, it was able to pull the lens cap and cord off without me knowing it, resulting in losing the cap. The eleastic band which attaches around the lens will stretch out over time so I find I need to replace them about every three years.

    Rated 5 out of 5 by from CHEAP INSURANCE CHEAP INSURANCE. Camera lenses are expensive and if you're traveling you can't replace one so you could lose the shot of a life time if the lens is damaged. Lens cap protects the lens and filter. Plus it keeps the lenses and filters clean and scratch free. I use these with all 5 of my Nikon lenses. Most shots you take the lens cap dangles out of the way of the shot. When you see the cap in the shot you you take the cap keeper off and put the elastic band around your wrist especially if your as absent minded as I am--I'm glad that my head is securely attached. For extra security I take the plastic piece off that has the 2 sided tape on it. These fall off the lens with time. I drill a small diameter hole in the lens cover. #55 drill should do the trick. Give some thought to where you place the hole--at the edge clear of moving parts on the back of the cap. Tie a double knot in the string and you're good to go.

    Rated 1 out of 5 by from Worked ok for a week I got a couple of these and used them on a couple different lenses. The elastic band on one lens kept slipping into a spot on one of my lenses that made it impossible to focus all the way. That was an issue. Also a problem was they didn't stick to the lens cap for much longer than a week of daily use. I was shooting in California and central America, so it was hot, but still... They are really inexpensive, but didn't work for me. I hope you have better luck.

    Rated 5 out of 5 by from A necessity if you are backpacking After losing two lens caps while backpacking this summer, I purchased this product and really enjoyed the convenience and security of knowing that my lens cap will not go flying into a glacial stream or down a cliff again. It is especially helpful when I am taking night time star pictures, having the lens cap hang there from the string and not having to place it somewhere and hoping you don't lose it in the dark. I found that on my last backpack trip, when I wanted to quickly take a picture of wildlife, I could just pop the lens cap off and take the picture, not having to place it in my pocket or somewhere else. Saved me a lot of time to get the shot I wanted without fiddling around with the cap. I secured my loop to the end of my camera strap which works for me more than attaching it to the lens barrel.

    Rated 4 out of 5 by from Cap Keeper OR Cap Keeper Plus??? I've been buying these for forty years. I was surprised to find 2 grades of Sensei Cap Keepers listed at B&H. I went for broke and ordered both. Cap Keeper Plus uses a heavier grade of elastic, a heavier cable, and it has a neat, plastic connector where cable and elastic join. The plebian grade joins eleastic to cablewith a metal staple, just as secure, no rough edges, but a bit raw. Also, the Plus version has a smaller S on the button that affixes it to the lens cap. As to effectiveness, in 40 years I've never had one that stayed stuck with the supplied adhesive. After the first lost lens cap, good epoxy holds it tight. CONCLUSION: Plus costs $1 more. I don't think it works any better, but if you're fussy about such stuff, perhaps it's worth the $1. For me, having satisfied my curiosity, I'll save future bucks.

    Rated 5 out of 5 by from Never lose the cap again. Clever design. With the self adhesive pad attached to the lens cap, and an elastic strap that fits onto your lens, not your camera, changing lenses is uninhibited. No more lens cap shoved into pockets gathering grit or getting lost.
