Hi I'm stilling trying to understand what all the different lens do and what they mean anyone got a good link to a web site or recommend a good book. Also want a magazine to read on photography which covers taking pictures and some info on kit so let me know what a good one is.

hmmm, not sure about a book but i'm sure we could all help you out.

Basically there are the following types of lenses...

Ultra wide angle zoom(eg.10-20mm sigma or 10-22mm Canon), these are designed to fit more of a scene into the picture, a wider field of view than normal, they are also great for architecture and indoor shots.

Wide angle zoom (eg, Canon 18-50mm etc. These are classed as your everyday 'walkabout lens', as they are ideal for walking about with, not too heavy and great for general purpose shots around town, wide enough for landscapes and you can zoom in a little to capture more detail in a scene, also useful for capturing people etc.

Telephoto zoom (eg. 70-200mm) These are great for motorsports and other sports, can be used at the wide end for portraits etc, not really suitable for everyday use as you won't get much of a scene into a single image, but don't let that put you off.

Super telephoto zoom (100-400mm, 170-500mm etc). This kind of lens lends itself perfectly to nature photography as you can oom right in on animals without disturbing them too much, also useful for getting close to a subject that's quite far away.

Macro lens (eg.Canon 100mm F/2.8 Macro) The most important thing to remember here is not to get mixed up with a dedicated macro lens and a lens that claims i has a macro mode, general rule of thumb is dedicated macro lenses are ALWAYS Prime lenses (see next section), with the exception of the Canon MP-E65 which has a kind of zoom range from 1:1 (lifesize) to 5:1 (5xlifesize). A Sigma 75-300 macro is not a true macro lens, but because it can get over 1/4 to life size it's classed as having a macro function, same with any lens that can get to 1/4 lifesize. The sigma 17-70 F/2.8-4 can get to half lifesize which can be useful.

Prime lenses (eg. 50mm F/1.4 /1.8, 85mm F/1.4 etc) Prime lenses are fantastic if you can live with the single focal length, i.e they have no zoom, they are light, but also VERY sharp due to having less glass for the light to get through, as mentioned about, all dedicated macro lenses are primes too.

Fisheye lens, There are a few fish eye lenses, usually under 8mm, they give a distorted image, kind of like a 'fisheye' effet, i'm sure you can google it.

Tilt shift lens (canon TS-E24) These are weird lenses, you can offset the lens to offer the focus point to any point in the image, google again to find out exactly what it does. These are useful for product photography.
 
Thanks for the info wez130, also wanted to know about F/1.4 /1.8, 85mm F/1.4 etc and what all the numbers mean :confused:
 
The f/x.x realate to the maximum apeture the lens has. The aperture relates to the depth of feild thte lens can produce.
Slightly more complicated because the aperture measured is in relation to the focal length of the lens.

for example the sigma 17-70mm f/2.8-f/4.5

it means at 17mm its f2.8 and at 70mm its f/4.5

Im sure someone can explain better.

These might come in useful :)

I use the 20D guide as I own one and it's very good so far, might not be of specific help for your camera if others.

As for the F number, they're the size of the aperture: bigger the number, smaller the hole (like the iris)

Don't try and learn everything at once!!

Aperture first is a good start. Not only does the aperture control the amount of light hitting the sensor (along with shutter speed), it also controls your Depth of Field (Large apertures, ie f/2.8 etc give a shallow DOF, small apertures like f/22 a wide DOF) The best way to find out is to do. Take pics of stuff at different apertures, and see how it affects the DOF

As you've bought a D200, look for a copy of the D200 Magic Lantern guide on eBay/Amazon - also, googling D200 guide is good!
