Confession: I just realized that this was taken at an 18 second exposure, not a 20-30 second exposure like I had thought.Please forgive me...

Hey Tommy--Question. For lenses..talk to me about the difference quality/usefulness wise between say an 18-135mm lense and a 70-300mm lense. I have been looking at some different ones and I see these two ranges a lot. Is it that you're going to get more "zoom" on the 300mm but wider angle with the 18mm? Is that why the 18-200mm is one of the best..you get both advantages? Lastly, how does the aperture effect your shot? I know that technically speaking what it does, with letting in more/less light--but is this something you mess with a lot taking pics? Does this just affect how light/dark the photo is?
Kyle and I went out last night and just took a few rolls of scenery and messed around--it was great. But, I'm looking into a digital now....
Hey Jen. Alright here we go....
1. Quality/Usefulness- You always want a quality lense (of Coarse). The better quality of lense the better quality of the picture. Its like if you have this great surround sound system that really pumps out clear crisp sound but you have horrible speakers. You will never hear the full potential of your system. So quality of the lense makes a big difference. That translates into a couple different things...a)glass quality.. you want extra low dispersion glass that allows for the greatest color and sharpness. b) how fast it focuses (this is usually determined by how low the aperature can go, make sense? so usually a 1.8 aperature lense will be faster in focusing than a 3.3 lense.........usefulness just has to do with what you want to take pictures of...you are right about the zoom being 300mm and the wide angle being 18mm.....for sports and animals, usually zoom is the way to go, but for everyday life your 18-135mm lense is better.
2. I love my 18-200mm. I does everything for me...and has Vibration Reduction too which is HUGE.
3. Aperture- Aperture does affect how light/dark the photo is, but it also works in conjunction with the shutter speed and what ISO speed you are using. As a rule of thumb- Big apertures like f/4 (f/1.8) will tend to have just one thing in focus. A smaller aperture like f/16 will tend to have everything in focus. How much is in focus is called depth of field. So most people use at least a f/8 when shooting landscapes because you want more in focus...but would use something like f/3.5 for a portrait because you only want your subject to be in focus.
I hope this makes sense....keep asking questions its great.
