Notes on Sigma 70-300mm f/4-5.6 DG Macro Telephoto Zoom ...- I love good lenses.
And I never thought something this cheap could be this good.
Was looking for a cheap tele zoom to use for a trip overseas, and found this one for next to nothing. I figured, hey, it's 70-300, it'll complement the 16-45 I have and probably be good enough for 4x6 prints. Boy, was I surprised. Even wide open at 300mm this thing puts out some excellent shots (I wouldn't think twice about doing an 8x10 or even 11x14 from the results), and it handles macro on top of that. Did a bunch of macro shots at 300mm around f/8 and I couldn't ask for anything better -- the colors, contrast, everything is just... really damn good.
Kudos to Sigma for putting out something this nice at such an affordable price. I hope a lot of people discover this lens and put it to good use, because as long as you don't need the speed of more expensive glass this is it.

Notes on Sigma 70-300mm f/4-5.6 DG Macro Telephoto Zoom ...- Purchased this zoom lens to accompany what I was getting in Pentax K10D "kit". For the price is a really good lens though I've had some issues with autofocus in "low" light (i.e. twilight). I haven't tried the macro function yet. When fully extended this lens is very long.
As noted in other reviews, the zoom action is stiff. Hopefully this will resolve over time. One big pet peeve is the lens screw-on shade/hood. It's just too big and makes packing the lens, in a camera bag, a pain since you either (1) don't use the shade/hood ever (2) get a huge camera bag so you can leave it on or (3) take if off everytime. I've found you can attach it "upside down" with the shade/hood facing inwards for storage. This save space somewhat.

Notes on Sigma 70-300mm f/4-5.6 DG Macro Telephoto Zoom ...- I recently purchased this lens from Amazon for use on my Pentax K100D Super. The optical quality and sharpness of the images taken with this lens far excedes its cost. While the build quality is a bit "plasticy" feeling, and the zoom ring is not that smooth, it produces very good results overall. Be careful to first read the instructions on use of the macro switch. It will not disengage unless you set the camera to manual focus and turn the focus ring. For nature photography in daylight this is a very good choice for those artists on a budget.

Notes on Sigma 70-300mm f/4-5.6 DG Macro Telephoto Zoom ...- For the money, this is a great lens. Sharp, reasonably fast and easy to use. I love the 300mm aspect, although at that length, you'd better use a tripod or a fast shutter speed. My Pentax body has antishake technology, which helps, but don't try to get great images hand holding the camera at 300mm in low light conditions.

Notes on Sigma 70-300mm f/4-5.6 DG Macro Telephoto Zoom ...- Bought this lens to go with my new Samsung GX-10. Haven't used it much, but have used it enough to know it's a great lens for the money. Images are clear at all focal lengths, very little vignetting that can be easily corrected. Good build quality. You can't go wrong with this one.
