Hi, I have recently bought a Nikon D40 DSLR camera, and instead of the standard 18-55mm lens it was equipped with a 18-70mm lens. I would like to know your opinion for this lens.
I have some technical questions, since the last time I did SLR photography was about 3 years ago in a high school program (only messed around with the 35mm cameras in ART class). I don't like reading tutorials and manuals and often find them very long and confusing (I understand things better if they were "summarized" or explained using everyday English), hopefully these questions won't be a pain in the ass to be answered and all help is very much appreciated.
1) What is the difference between ISO and exposure? How is shutter speed affected? I noticed that sometimes the shutter speed is 1/60 and sometimes is 1s using the same ISO. How do I manually control the shutter speed?
2) Aperture? Focal length? White balance?
3) What does 18-70mm means? 1:3.5-4.5? What does these values mean on a lens?
Sorry in advance if the answer end up being a 10 paragraph long tutorial. :/
