So as some of you know from yesterday I was planning on purchasing the 70-200mm L f2.8 lens. As I looked through all my lenses I've been wondering about that decision. My current full time lens is a Canon EF 28-135 f3.5-5.8 IS USM. I have a few other lenses but they are entry level and I don't like the quality of them anymore so I will probably sell them. I realize that if I get the 70-200 I will have a boatload of overlap between my two lenses that I will have left. Given this, should I get something else? My shooting mostly consists of landscapes while hiking and such, but I have done 2 weddings that went pretty well although that isn't my overall plan... I don't really want to do weddings except for as a favor to friends that are poor. I also LOVE doing night shooting and the 28-135 doesn't do an amazing job in low light. Does anybody else have this lens? Maybe some pointers for night shooting without a flash? Cliffs: Sell it all and get two separate lenses, or keep my 28-135 and add on with something else? Landscapes and night shots are my favorites.
