A few days ago I started a thread about which Canon DSLR to get. I am pretty much locked onto the 40D... which looks like it uses EF & EFS lenses.. I think.? Now for lenses, I may not buy all these now, but could ya'll show me some lenses for : Macro Tele Photo / Zoom tele photo & (What is the difference between the two)? Wide Angle Lens Standard all purpose general lens if there is such a thing... I guess like an 18-75 or something....? I am almost 100% ignorant about lenses, so plz explain everything you can, Thanks!!
