how dslr camera lenses work image
Belle
So I am wanting to buy a camera, but I don't really know what to look for. I know dslr cameras have interchangeable lenses, and a standard one seems to be 18-55 mm. What does that translate to for zoom relative to a p&s? (Like, is it 30x zoom or something like that?)
Answer
If you are going to spend real money on a DSLR you need to stop misusing words. A zoom lense is a variable focal length lense. 30x is totally meaningless. 30x what? An 18-55mm lense can be set to any focasl length between 18mm and 55mm. Nothing else has any meaning unless you know the dimensions of the sensor the image will be focussed on. Then you can calculate the angle of view options available for a given focal length range.

What are all these FF55 - 200 stuff on the DSLR camera lenses?

I'm getting a DSLR camera for Christmas and I don't know what all these funky letters and numbers mean.
Thanks in advance!
Answer
Labels, Numbers, They stand for different things.
If you just bought a DSLR you can go to the brand DSLR website and find information about such.
55-200 means that the lens has a 55-200mm focal range. Your kitlens has 18-55, in effect from a group shot to a relative thigh shot. And the 55-200mm is a lens in the tele range meaning it can pull closer for instance a bird in the trees.
Ah you can even see it in effect if you move one of the ribbed rings on the lens you see it extend a bit. Now look through the viewfinder and do it again. Hey wasn't that easy!
The other ring is for focussing, it allows you to manual focus if for instance the automatic focus doesn't cuts it [dark outside or something in the way]
What the other things mean..well that depends on brand and lens brand.
I agree with the others best is to buy a book into the basics of DSLR and read it, keep it with you and most important MAKE ALLOT OF PICTURES. The only way you can learn is through experience! And that means actual doing it.
DSLR's are great tools, but at the same time they are tools, it is the person behind the camera that makes the magic happen. Yes it offers auto modes but one of the nicest thing about the DSLR is control. You get the shot as you desire!
So buy a simple starters guide for your specific model [for instance if you own a Nikon 3100 buy a book that with pictures and easy words tell you what the buttons are for and what does what]
Then buy a book about different types of photography and well again with nice pictures inside so you can see what they mean.
Photography is an art, it is something you can almost touch, taste, feel.. but also it is a technical thing.
So just buy some basic books and actually make pictures. Learn the way get hooked on it.
