Question by cheekymunky274: Digital photography lens help?
Ok so, I’m pretty into photography. I love to take pictures and look at other photographers work. I find everything about photography interesting and I took a film photography class in school which focused mainly on taking pictures and developing them. Now, My class is over and i realize i really don’t understand much about lens’ or how they work.
I have a canon rebel xs which came standard with a
58mm EF-S 18-55mm f/3.5-5.6 lens
and then i bought a
58mm EF 75-300mm f/4-5.6 len for about $ 150
I didn’t really know anything about the one i bought, i just bought it because i saw pictures that were taken by other people who had purchased the lens. What does 58mm mean? Could I buy a lens thats 50mm?
What does the 75-300mm mean?
What does the f (4-5.6)mean?
Now I want to buy a macro lens to take pictures of things very close up. My budget is very small, I was thinking of looking on ebay. Under $ 1000 definitely. Which one would you suggest?
I also like the ultra wide angle lens’. Any suggestions to a good one?
Thanks in advance!
Oh and if anyone has good websites that have lots of information and is easy to understand, that’d be great.

Okay…
The “millimeters” represent the length of the lens when it is retracted, or extracted. I hope that’s clear enough. i.e. – the 73mm is when you have the lens at the widest angle – the 300mm when you have it fully zoomed in.
The 58mm is the width of the end of the lens – the cap, if you like. the glass at the end. The wider angle, the bigger the number.
The f(4-5.6) is the f-stop, or aperture. This controls the amount of light that enters the lens.
For the last two, consider thinking about Tamrons, or Sigmas. These have fairly good prices.
