It's the ideal high-performance lens for portraits, sports photography, nature photography and other types of photography that frequently use the telephoto range.

Amazing lens,
By A. Reader (London, England) - See all my reviews
This review is from: Sigma 70-300mm f4-5.6 Macro DG Lens For Pentax Digital & Film SLR Cameras (Electronics)
I didn't have huge expectations from this lens. Bought it for a Pentax K-x and wanted something longer than the 50-200mm zoom which came with it. The Pentax 50-300mm was much more expensive, nearly triple the price. This lens becomes a fantastic buy for Pentax because the stabilisation is built into the camera body, maybe less so for Nikon/Canon users.Anyway, it's one of my favourite lenses, even compared to some which are far more expensive. It's big, especially with the hood on it, but light in weight, it's reliable and consistent. I haven't yet tried the macro, but it's nice to have the facility. The main thing about it is the delicacy of colours. There's something about the lighter shades which it does extremely well, it's a 'happy' lens, and in comparison (if you have a look at the View and Share Images for the different lenses) the more expensive Pentax lenses seem a little muddy (which they're not, it's just by comparison). That applies just as much, by the way, to the Canon/Nikon lenses and bodies which seem much more clinical and sober than this lens does on Pentax. So even though I was looking for a secondhand Pentax 50-300mm, which would be a bit sharper, I don't think I'll bother now. If I want sharp, I can always just stop this lens down to f8-f11 and use a tripod. Sharpness for its own sake in photography is vastly overrated unless you're doing something technical. This lens has magic, which you cannot measure with a test chart. I'd much rather have the pleasing colour rendition of this Sigma, which is excellent for portraiture and candid photos of people, especially in decent light. For portraiture, I would much rather use this lens on Pentax than my Canon 100mm f2 on the 600D, which is a far more expensive combination. If this lens were broken or stolen I'd order another one without hesitation. The only thing you need to be careful of is that, when removing it from the camera body, it's wise to turn the auto/manual switch on the camera to manual, as it's too easy to grab the lens by the bit that focuses and strip the gears. That's not a criticism of the lens, just something to watch. Turn the switch back to auto once the lens is off the body.

I bought this product purely by reading the reviews on this site, some good, some bad, some indifferent. what a bargain, this lens give pinpoint sharpness to the user, motor is very quiet, focus is quick and simple, macro is very good for close-ups, to me this lens is a one stop shop, only one very slight drawback is that the lens is a little heavier than expected but nothing to be unduly worried about

Sigma 70-300mm lens,
This review is from: Sigma 70-300mm f4-5.6 Macro DG Lens For Pentax Digital & Film SLR Cameras (Electronics)
I recently purchased a Sigma 70-300mm lens for my Pentax digital SLR.It is a realy good lens, not too heavy, a very good zoom, easy to use, maintaining a sharp image right through the range and the macro is fist class. I have always used Pentax lenses but this one from Sigma is considerably cheaper and does everything a lens costing twice the price can do. I have been an amateur photographer for over 40 years, used all sorts of cameras and lenses and would definately recommend the Sigma lens to other users.
