Advantages: value for money (compared to pro level), build quality, Disadvantages: makes you think your a pro, but by its nature, proves you otherwise.
This sigma lens is often a favourite starting point for digital SLR users (single lens reflex) looking to upgrade the 'kit' package they bought on impulse in the January sales.
"I know, I've got a million pix of my children and cat, now I'll photograph flowers and insects with a macrolens, whatever that is".
Don't kid yourself; the whole idea of this lens is to get close-up and personel with your subject matter (insects and flowers being two of my favs). If your looking for a mid-sized telephoto lens just to add to your camera bag, go and by a mid-sized zoom lens. Macro photography is not for the faint-hearted. It requires patience, skill and an understanding beyond that of the family photo album. But the rewards are excellent.
With a good, solid build quality and good optics; it is worth buying if you can't afford a pro ...
Advantages: Optical quality. Build quality. Price. Disadvantages: Could come free with Cornflakes?

Also included, is a decent lens hood (also not included with the Canon lens) and a superb soft case. Bravo Sigma! Of course, if you use any other marque than Canon, the Canon lens isn't worth discussing!

It is also a DG (Digital Grade) lens, meaning it has all the latest coating technology to help prevent flare and 'ghosting' from light being reflected back off the shiny digital imaging sensor in modern DLSR cameras. The good news is, it really does ...
Advantages: Good build quality and good value for money . Disadvantages: Sigma`s claims not met and a slow auto focus .
Owners and uses of DSLR cameras will know that there are dozens of different lenses that can be attached to the cameras to enable different types of photography to be done correctly.
The original or kit lenses that come with most DSLR`s are capable of doing a bit of everything but only at low levels, if you want to take certain images, get long zoom possibilities or shoot creatively then you need to get the right lens for the right job.
One favourite with a lot of DSLR users is Macro photography which is basically shooting close ups of things, the average cameralens will only focus properly at a minimum distance of around 59cm whereas a macrolens will let you get in much closer. This particular lens (Sigma EX macrolens - 50 mm F/2.8) allows you to focus on objects as close in as 20cm.
Sigma make many other claims about ...
