That you will just have to flip a coin for lol. Which one do you think you will use more of? If it was me I would pick the 35 f/1.8 since you already have the kit lens and has some zoom already.Yea is it nice to have a 200mm for the construction but if that's all your using it for I would go the other direction. Really the only one you need zoom for is HP 2.0 and even now you cant really see too much of Gringotts.
