Hey folks, If you are reading this, thank you. If you can give me some advice, even better! My wife and I are planning to travel to Europe in September. I don't want to carry multiple lenses so I have the option of renting a single lens. I have searched the forums and found some answers which suggest a wide angle lens. I also have the following lenses: Canon EF-SKit Lens 18-55 mm f/3.5-5.6 - OLD. Ok lens. Canon EF 85 mm f/1.8 - Great for portraits. I love this lens. Canon EF-S 17-85 mm f/4-5.6 IS. Great for bright outdoor shots. Very poor indoor or low light performance. On the other hand, I have the option of renting a good lens. What should I choose given: I like to take shots of buildings and landscapes etc. So wide angle would be my choice. My wife obviously likes lot of shots of herself or with me with a background. I definitely want to take a fast lens. I am thinking at least f/2 but I am not sure. Will a prime lens do background shots well? The 85 mm above has great bokeh but is usually not good at one or more people at close distances. I have a Canon Xti (I bought it when it first came out adn have enjoyed it since then. No budget to upgrade yet). I have looked at Canon 24-70 f/2.8L - No IS though. Canon 24-105 f/4L IS - Slow though. Canon 24 f/1.4L - No IS but fast. But this is a prime lens. It looks like Tamron lenses might be a good option too but I have never used them. What would you suggest? Thanks, Vijai.
