I'm going to order a new Canon 550d in a kit with a lens. I'm fairly new to SLR photography which means I have not much knowledge about the difference between lenses.
There is an offer for a Canon 550d with the very common EF-S 18-55mm IS lens and an (more expensive) offer with a EF-S 18-135mm IS lens. I'm unsure about which one to buy.
My current knowledge tells me that the cheaper lens (18-55mm) has a more limited range and cannot zoom in as much as the more expensive 18-135mm one. The later one is also bigger and more heavy, right?
Are there any other differences but the maximum zoom-factor? Are both equally good for beginner-macro shoots? In which cases would you recommend which lens? Does it make sense to buy the kit and purchase the other one separately?
