I just got a Sigma 70-300 APO Macro Super II. Here's one of my first shots. Not exactly super sharp, but it's so hard to get a sharp shot at 300mm while panning like mad trying to catch a seagull in flight. It was even luck to get it in the frame I manually focused this while panning. I decided to do the soft focus in PS since the photo wasn't tack sharp to begin with. Whatcha think? I love the lens. I'll be out tomorrow shooting all day with it I suspect And one more, this one's a bit sharper, thankfully.
