Here are some more information for Lens Caps:

It's all very well being kitted out with cutting edge binoculars, telescope, tripod and the latest field guide, but all that costly birding gear will do you little good if you can't get close enough to a bird to see any of its plumage details, or if it flits away before you even clutch your binoculars. That's where birding fieldcraft comes in: an important but all too often neglected aspect of modern birding that could greatly improve your birding success.
As birders come in almost as many forms as the birds themselves it seems fair to start with what would appear to the more initiated as rather banal advice. However, based on personal observations of the birdwatching fauna it should not go unmentioned: binocular cases are for the home only! Whatever reasons you may have for wanting to keep your binoculars in their case when out in the field (avoiding knocks, keeping them clean, looking trendy, etc.) this practice is contrary and even pernicious to your reason for being out in the field in the first place. Binoculars are a vital tool for any birder and they should be ready for use at all times. Remember the bird won't usually wait around for you to fumble with straps, lids and lens caps. If what worries you is keeping your binoculars dry in wet weather then get a rain guard or grip them under your jacket in Napoleonic style, but do not keep them sealed in a velvet-lined binocular case!
Essentially, though, a birder's level of fieldcraft will be a result of his/her attitudes, preparation and resourcefulness. For the sake of space the latter aspect is best left for a later moment. What is meant here by attitudes is the birder's preconceived ideas that lead him to act in a certain way when out in the field. Preparation concerns things such as clothing and other birding gear, planning and perception.
Attitudes. A birder who sees a flock of gulls and says "Ah, a flock of gulls" and moves on is missing out on an important birding experience. Faced with a flock of gulls, ducks or waders numbering anywhere from 30 to 3,000 the keen and knowledgeable birder would fidget or twitch in response to a sudden surge of adrenaline. Birds of a feather flock together for sure, but he knows that the average such flock offers opportunities of finding birds with different plumages, moult stages, different species and, with a lot of luck, a rarity.
Rarities and attitudes towards them could occupy a category all of their own but a basic message would be to bear in mind the possibility of finding a rarity without taking this to obsession level. Remember that rarities are rare, so always consider a more common candidate when trying to identify a particular bird.
Preparation. If it is possible to plan your route beforehand then do so to avoid looking into the sun as much as possible. That means taking into account access routes and times of day; it's a simple task that at certain sites can deliver large rewards in terms of the quality of your birding experience. Wearing the right clothing is also important. Think about sunhats, waterproofs, climbing boots or Wellingtons, but also ask yourself about colour and rustle. Bright red jackets do not blend in with most environments, and if you rustle or swish with every step you won't be able to hear the birds but they will most certainly hear you.
Get used to listening to birds, not just looking. Most birds can be identified on song or calls alone and if you master local bird songs and calls you will be able to know exactly what is around you without having to spot every single bird. The vocalisation learning process is a long one, which can be helped along by listening to CDs, downloading birdsong and calls from the Internet, and most of all by going into the field and listening hard. Long the process may be, but it is also extremely rewarding.
Have a notebook and be prepared to take field notes, recording details such as place, date, companions names, species and numbers detected. A notebook is a very handy tool when faced with a possible rarity, and also makes for interesting reading at a later date.
Listen again. Be an active listener by asking yourself if you really are listening. There's almost always a bird calling or singing around you, have you heard it it and identified it?
Get to know your birds, including their habitat requirements and selection. You will then be able to come up with such gems as "This looks ideal for a (bird name)," as you survey a new landscape, raise your binoculars and instantly set eyes on the bird you have just mentioned. At such times its hard not to swell with gratification.
You are allowed to wear any kind of silly hat that you like. There is no firm evidence that even the wackiest designs have any influence on your success or failure as a birder, although it really is better if your ultimate choice is suited to local weather conditions!
One more thing: start now - what's that bird calling outside?

Lens Cleaning for Laser Pointers - Tips and Instructions
One of the most common problems you can have with laser pointers and one of the easiest to fix is dirty lens. You can tell the lens is dirty when the beam point is spotted or out of shape instead of the normal small tight circle.
There are many ways to clean the lens of a laser pointer such as q tips, microfibre, cotton buds and alcohol solution. Some of these may work, others will not but they all run the risk of damaging the lens. There are only two methods of cleaning lens that work well AND will not damage the lens. Those two methods are using compressed air and using professional lens cleaning tools such as a lenspen.
Compressed air and lenspens
The most common sources of compressed air are cans of compressed air and hand pumps or squeeze bulbs. The main criteria for compressed air sources is the air must be clean and dry. This is one reason why blowing on the lens is not recommended.
The best professional lens cleaning tools are lens pens from the company lenspens http://www.lenspen.com These lens cleaning tools are safe and suitable because they are designed to clean fragile precision optics such as camera lens.
Instructions
Safety is always an issue with high powered laser pointers so the first thing you do before cleaning the lens is remove the batteries from the laser. After removing the batteries, leave the battery end cap off as an extra precaution.
Compressed air will be able to clean 90% of lens so try using compressed air first. Gently unscrew the lens cap and with the nozzle held two to three centimeters away from the laser, direct a flow of air onto the lens for several seconds.
Install the batteries in the laser and test the beam. It should now be clean. If it is not, remove the batteries again and use the lenspen.
First gently use the brush of the lenspen to brush dirt and debris off the lens then use the pad on the other end of the lenspen on the laser pointer lens for several seconds to clean and polish the lens.
By the end of this process, then lens will have been thoroughly cleaned. If there is still a problem with the beam point or beam, it may be due to damaged lens.

What lens cap size do I need for my camera?
I just bought a FujiFilm s1000 on eBay and it didn't come with a lens cap. Does anyone know the size cap I need to buy? Thanks for the help. =)
If you look at the marking on the front of lens barrel you will see the size a zero with a line thru it and like 87mm that is the size of filters and lens caps that will fit the lens.
