Before we got the Tamron 90 2.8 macro, I thought the 70-300 macro was worth keeping the lens for. I'm still thinking it does well up until about 135mm, I'm definitley not impressed with it's performance between 200mm and 300mm. We have a DA*60-250, but we also have two photgraphers, so often the Sigma 70-300 still comes along. And at close range it's magnification is about 50% more than the 60-250 and it's very sharp close in. If all you have is a kit lens, and you want telephoto and macro.. this is the lens to get. It was half of a two lens kit for me for years. IN that capacity it's a great lens. It didn't really become redundant until we got the DA* 60-250... at 5 times the price.

I wouldn't say that PF is "easy to remove". It can be mitigated to a greater or lesser degree. However, one should realize that PF (and all kinds of CA) results in a loss of image data, we just hope it isn't in an area of the photo where this is important or noticeable. Also, most methods of reducing PF result in the "fixed" areas being gray, and this isn't always appropriate to the image.
agreed. I know 3 or 4 methods of reducing PF in Photoshop and I still spend precious time dealing with it for the pics that matter. To do it right is not a walk in the park in many cases.

Just figured I'd bump this thread because I went to a firemen's parade today, and wound up using my busted up 70-300 non-APO Sigma for the duration. All shots were at f/8 at various lengths (most shot at 70mm however). I'm still uploading the mega-batch of shots to my flickr, but to get an idea of what even the 'worst' sample of that lens can do, feel free to check it out. I'll be shoving all the images into a set once I can get in and tag/rename the things. Only PP (except for excising a few things from a few shots with content aware) for all was cropping and auto levels/tones/contrast in Photoshop, everything else was the Sigma and my K-x.
