I don't lose lens caps often but when I do it makes me mad. You've got to have them--lenses are expensive and there's no better way to protect them from damage on an ongoing basis. I've been getting them from the manufacturer of my camera. They're a lot more expensive than you'd think they'd be given their simplicity. This is the case with any quality camera/lens maker. I thought I'd give these a try since the last time I had to replace a lens I paid twice this amount for one cap. These work great--they don't have the logo of the aforementioned camera company on the front but otherwise they work and look just like the OEM. I've now got backup caps for my most used lenses and I'll be ordering some more! I don't use the anti-loss leashes because I find them awkward--personal preference--but at this price I don't worry about losing lens caps any more. They even include three vacuum packed microfiber clothes which I stash in all of my bags. Highly recommended!!

A nice little kit from K&F. Honestly, these aren't my favorite lens caps that I've handled, but they nonetheless seem plenty adequate and sturdy. I'm just a bit fickle about the plastic and injection molding quality, but these seem to work just as well as my other caps from other various brands.

The caps come with a pre-tied lanyard loop, and also adhesive buttons with elastic leashes for attaching the cap to your lenses. Personally, I'd rather just stick the cap in my pocket, but appreciate that these come with multiple retention options.

As well as the caps, these also come with three vacuum sealed microfiber cloths. Another nice to have bit of kit, that should serve as a durable and reliable tool, and with a convenient package to stuff them in various pockets or bags without worrying about dirtying them.

I've got a Nikon camera; I like to take photographs... But sometimes I lose a lens cap. These 77mm caps fit my lenses perfectly. They clamp on securely. I have lost a couple of caps in the past by having them pop off at an inopportune time, but as a photojournalist, I'm busy running around, getting into position for a good shot. I don't always keep an eye on my lens caps. These seem to have a great grip on the filter. The cleaning cloths are very fine and should help to keep the lenses clean. I have not been a big fan of lens cap leashes in the past, as they just seem to get in the way, but might try one to see if these are better than the one I used for a bit years ago. The price is great, and the quality is there, so these are a good purchase for a pro or a casual photographer.

I got this for the lens caps only... I don't use the keepers and I already have a comically large baggie full of new microfiber cloths as it seems they come with almost everything these days.

BUT due to having a lot of lenses with smaller filter ring diameters that I size up to 77mm using step up rings so they can share a common filter size, I do often find myself running around on a shoot with an unprotected 77mm filter on the end of my rig.

These are exactly the quality you would hope them to be. Nothing fancy, but perfectly functional and easy to use/operate, with one hand, without looking. The set of three is useful because I need at least that many and will absolutely lose them all over time in the black holes that are my pockets.

No complaints!

This is a good deal on a set of light-weight replacement or extra lens caps -- this is a set of three and each includes a leash (the band fits around my lens and does not obscure the markings + the disk has a small pad that adheres to the cap; just remove the paper covering and stick it in place).
I have two older Pentax film cameras (I guess they are considered vintage, now -- sounds better than obsolete, anyway). They are actually the same model, one belonged to my father and I later chose the same one when I started getting interested in B&W photography. The original lens cap on one of them was lost long ago, but the camera is kept in one of those fitted cases so the lens was protected. Unfortunately that case is now falling apart and I found this kit which seemed perfect for my needs. Most lenses are marked with a Chi symbol followed by a number designating the diameter of the lens (as shown in the pictures in the product description) but not all lenses have this, and as it turns out, mine do not. It is possible to measure them using a metric ruler or tape measure, but being very much an amateur photographer, I wanted to be absolutely sure, so I looked up my 50 mm lens online. It turned out to be a fairly popular one for the time (30+ years ago) and I found a website that showed all of the specifications, so I felt confident ordering the 49 mm version. These caps are not as robust as the original ones -- they thin and lightweight but they are easy to position (just pinch the slides on each side to install or remove). They fit securely on my lenses don't pop off easily and I feel that the glass I well protected. I really like the leash, as I am always losing lens caps that don't have them (I take them off and put them in my pocket or set them down and forget where). I really ordered this set just for the lens caps and I really like that there are three of them, so I have extras. The microfiber cleaning cloths are of very good quality, too. There are three and each is packed in a separate foil packet. The squares are a good size (about 6" X 6") and are a very fine gauge, very soft and silky. They are a welcome addition to my camera accessory kit. The current price of $14.99 seems very reasonable to me.

I use a Sony camcorder with a lens cap that will roll underneath a stage from time to time. These lens caps fix this problem. I was able to order a 62mm and it fits! I didn't think I would have to tie the string that comes with the cap, but I was able to figure out that a simple knot will secure the lens cap to the lens hood, and it's good to go. The string that comes with the caps is a well made, kind of rubbery string. It's not just a piece of string. So I won't need to replace the lens cap ever.
