Review title: Excellen Lens - Sharper than My Old Minolta 100-300
Product review: Although somewhat larger and heavier than my 20 year old Minolta 100-300 zoom lens, the Sigma was exactly what I hoped for when I ordered it. At 300 mm on a tripod mounted Konica Minolta Maxxum 5D, I was amazed at how the Sigma lens was noticeably sharper on my test subject (the front page of our daily paper) than the Minolta lens. I have had good results when photographing butterflies and similar small delicate subjects.
