Decent starter lens.......2007-12-15

I've had mine a few weeks now and am generally pleased with results given the price.

There's a couple of gripes that I have however. As others the autofocus gets confused and doesn't focus on anything, but that quickly sorts itself out. More importantly is that the lens cap is rubbish and frequently falls off when in my bag which will lead to me damaging the lens sooner or later. To put this in perspective, the lens cap of my Canon kit lens always stays in place as it should.

Alright for a starter lens.......2007-08-27

This lens is at the cheap end of telephotos, and its performance certainly depends on the users level of expertise. Starting at f/4 means lower shutter speeds, and handheld shots at 300mm on an APS-C camera can be tricky, but not impossible.

The build quality of this lens is fair, it's not a tank, but it's not plasticky either. It's definitely a happy-medium. The lens itself is light, which makes telephoto shots slightly harder but does make this lens couple better with lighter DSLR cameras.

A major niggle I had was that the macro switch would get stuck once engaged, and then the lens barrel would not go back to its original size. This means you need to switch back to manual focus, readjust the lens extension, and then you will be able to fit the lens back to its original compact size. This is a widespread issue as far as I'm aware, so I'll have to knock points off for that.

As far as image quality goes, this lens is neither good nor bad. At 70-200mm the quality is reasonable, but there is a drop off in quality further towards the 300mm end. Colours are vivid, thanks to the APO coating. And sharpness is as stated, good throughout although dropping towards the 300mm side.

The autofocus is fairly snappy but sometimes hunts for a little while, it's not silent either. It's not the loudest AF out there by far, and I wouldn't say this is a downside at all. Especially when you're working at around 100cm from the nearest subject.

Taking all into consideration, this is not a bad lens. Very far from it, in fact. I would recommend this to anyone starting out and perhaps in search of a first telephoto lens. But for enthusiasts and higher, I would suggest spending more and looking at better-quality alternatives. I would rate this lens 3.5/5 but granted it served its purpose and got me a few cracking shots I'll up it to 4.

I hope this helps!

Good starter zoom.............2007-08-24

Being new to photography I rely on these posts heavily for advice and recommendations. After much research and advice from many online reviews I decided to purchase this Sigma lens rather than stick with the Canon aternative. For the cost I canot fault his piece and for where i am at the moment it's perfect. My only grpe is that its a little heavy. If like me you are in the market for a starter zoom then I highy recommend the Sigma.

Brilliant lense for the money.......2007-06-04

I use mine with a canon eos400D and the results are very good

Only just received it so I've not fully experimented. I've used it outdoors in good light for macro on flowers and objects, some landscapes and nature all without tripod. AS the other reviewer says watch for the macro button sticking on you might have to manually focus back to normal before you can turn it off (only works between 200mm and 300mm). Comes with a nice upright storage pouch to protect in transit also a lense hood. Seems worth the extra bit of money than the cheaper non APO lens and also the Tamron and canon USM equivalents. You may need to manually focus occasionally as it doesn't always focus spot on to the object.

Sigma AF 70-300mm f4-5.6 DG: A good zoom lens for beginners to enthusiasts.......2007-05-09

This is a beautiful lens, and works really well with my Canon DSLR. In terms of asthetics, the touch is a nice smooth matte finish, and it glides perfectly in both manual focus and zoom.

As an extra, it also features a "macro" button, so that you can switch to macro mode, which is perfect if you want to take photographs of birds or other wildlife from a distance, without needing a dedicated macro lens to get close to them.

This lens is a good all-rounder, and its always in my kit when I go out photographing. Perfect for taking shots of landscapes and picking out specific points of interest, or for picking out architectural detail when you're out in a more urban environment.

The only downside, is that I find the "macro" switch can stick a little, and I need to switch it to manual focus mode before I can turn off the macro mode.

It is quite heavy, but fine for general outdoor photography, otherwise a tripod or a rest is recommended.
