Hey everyone! I'm going to Switzerland in a month's time and I really want to get all my Photography gear together. I'm looking for any lens suggestions (if I need any) that can be useful. Right now I am into Photography as a hobbyist but I enjoy it, therefore I want to have the right equipment etc. Currently, I own a Canon T3 with the 18-55mm Lens, 50mm EF Prime Lens f/1.8 and the Canon 28mm-135mm. Recently, I also just bought the Canon 70mm-200mm EF f/4 L Lens. Should I return the Canon 70mm-200mm (purchased it two days ago) and buy another lens or keep it? I find myself not being able to clear photos without the IS feature on the lens and honestly, I don't have the extra $500 to spend on the IS version. So should I keep the lens I have right now or return the Canon 70-200mm for some other lens. I plan to take pictures of landscape, nature and people. Thanks for the answers in advance.
