im sure alot of us who are in this hobby has always dreamt of owning a macro lens sometime in there life time. I finally found the courage to jump in and grab one. I was on the market for a 2nd hand lens that was in mint condition and had 2 lenses in mind:
canon EF 100mm USM macro
sigma 150mm EX DG HSM macro
both are great cameras and my budget was $700
i finally found a sigma 150mm macro for $700 in mint condition, no scratches or anything and is only 10months old. thats close to $420 worth of saving if i was to buy retail and pay for a brand new + tax!! so i bought it instantly. and took a few pictures with it and WOW it is an amazing lens, much sharper imo than the canon EF 100mm, but it might just be me being crazy.
