Answer
The numbers tell you the focal length of the lens. These are "zoom" lenses. The one with the larger numbers will zoom in on a distant subject more than the one with the smaller numbers. They sound like Canon lenses, so I will say that the 18-55 lens is the standard kit lens. It has very wide application and is quite useful for everyday shooting. It would be good to use either indoors or outdoors for most subjects.
If it was a telescope, the 55 mm end of the zoom would be called almost a 2-power telescope, just to give you an indea how big it wouldmake things look. In other words - not much bigger than a normal view.
The 28-135 lens would probably be more suited to outdoor use, as it will magnify the subjects and make them appear closer to the lens. If you try to use this indoors, you CAN, but you would be taking mostly pictures of peoples heads or head and shoulders and not too much else out at the 135 end of the zoom. The 28 mm end is close to a "normal" view, so you COULD use it indoors, but you'd find yourself backing into the wall if you go to far towards the 135 end of the zoom.
You can look these lenses up at any of the sites listed below. The first one has a few nice articles on choosing a lens and it tells you what focal lengths are good for what subjects.

Digital Camera ?
Jim O
I'm looking to buy a decent digital camera for about £150. I know I wont get a top of the range camera for that. I'm just looking for something that will take high quality photographs, and that I will be able to just put in my pocket. Also I want something that won't break within the first month of having it. I was looking at the Panasonic Lumix FS3, the 8MP one. Or the Samsung L313 13MP. Any suggestions? Doesnt have to be between them 2 either.
Thanks!
Answer
There are so many cameras out there it is difficult to say which is best, but digital is definitely the way to go. The following link will be very helpful as it list most of the cameras out there with prices. http://reviews.cnet.com/digital-cameras/
What gives a camera its picture quality? The following information should help you know what to look for in a camera.
The short answer is that it is mostly the skill of the photographer that produces high quality pictures. The lens and camera are very important, but the ability to set the scene, adjust the cameras settings, and hold the camera very still or use a tripod with auto or remote shutter actuation when required is what gets the great pictures.
Many of the new cameras come with only an LCD screen. Would suggest that you find one that also has an optical view finder because the LCD screen is almost impossible to see in bright sun.
Higher mega pixels may not really be the best thing to look for. It is more expensive, takes longer to process, and may not be needed unless you are making a really large picture or blowing up a small part of a picture.

Check this more for the money camera. FUJIFILM - FinePix 10.0-Megapixel Digital.
Life time Warranty (Parts & Labor).
Wide-angle shooting, a 12x optical zoom and picture stabilization mode combine in this camera for exceptional shooting performance, even at a distance. Plentiful scene modes, autofocus and automatic white balance controls make this camera a snap to operate. You may be able to find it on the Internet for a lower price ($144), but be careful of the vendor.

This could be the best slim line camera with a viewfinder. It's PINK!

The information about my camera is just to show that you don't need the biggest and best. Just know how to use the one you have.
My camera has 5.2 mega pixel, but I use 3 most of the time because it gives great results, is faster, and takes less memory. Also, it only has a 3 x optical zoom and 7x digital zoom. I never use the digital zoom because making pictures larger works better on the computer. This is an old camera, but everyone is impressed with the quality pictures it takes ... like magic.
Check with the Geeks in several stores and compare prices. Ask what cameras they own, but don't believe everything you hear. Once you select a camera read all about it in the owner's manual. Just learned that my camera has red-eye prevention and correction. It also has adaptive lighting. You may be able to view the owners manual at this link, but will need to Login. http://www.retrevo.com/s/digital+camera ...
