I assume many of you have been in the same position with your spouse before. I recently purchased a Rebel XS with kit lens. Needless to say, I'm not really that impressed with the kit lens, as it simply is not fast enough for indoor photography of a hyperactive 21-month old. I want the 50mm f/1.4 badly.However, this takes a bit of convincing of my wife, who is not "into" photography, only sees the fact that I just dropped $500 on the camera not too long ago, and desperately wants a new house (which is going to happen regardless of this $325 lens). Anyway, what are some strategies you have used in these types of situations?
