Do u really need to do macro? I mean only get this lens if u are SRRIOUS about macro!! It's expense and TBH I didn't use it nearly as much to justify the cost, however it's a great lens and is a sharp one too!
Try and get one that's made in japan as they ate now made in china. I just got mine about 7 months before they moved to make them in china.
