Of course, I don't think I will be keeping both as their focal length are too close and both have f/2.8 aperture. However, I plan to take my time and not make a hasty decision. I was originally tempted to do one of those "shoot out" type test where I would shoot the same subjects with both lenses and compare which one produces the image that I prefer. I may still do that, but I feel it's too analytical and takes away the "enjoyment". Instead, since I have them in hand, I want to really get to know each lens so the decision won't be based on images alone, but also on ergonomics, how they feel in actual use, and just my overall impression after using them for a few months. So, this battle will be one of many to come... as I will bringing both lenses with me, giving both ample time of usage, and let the results speak for themselves. It's a tough job, but somebody has to do it :)
