Title: Great lens, but be sure you really need it before buying
Review: Two reasons you should consider this lens:1) You make money from photography and every last detail or amount of color saturation matters, or2) Money is no object.Remember, it is not the lens, but the photographer, that makes great pictures. That being said, a lens of this caliber can squeeze that extra fraction of vivid detail/color out of many shots. However, unless you are making money from photography or just have money to burn, those improvements are costly and fractional.It is also very heavy and big...not exactly good for the wife to pick up and use to take kiddie pictures.I own many lenses that csot much less than this lens and I have many shots I would never part with. Don't oversell yourself, unless you can justify it using criteria 1 and 2 above.4 stars b/c it did not impress me on too many shots, for the money I spent on it. Which reinforces the point that it is the photographer, not the lens, that really matters.
