I take alot of pictures at concerts, mainly punk shows or shows where you can be close to the stage so zooming isn't a huge issue. (If I'm at bigger shows I'll use my 100mm Macro lens because its 2.8f and usually fast enough in low light situations, and takes great pictures too.) This lens is great for concerts, I can generally take pictures at any show without the use of flash. I've used this lens on a Rebel XTi and Elan 7NE and had great results with both. I use this lens the most out of the ones I own just because you can use it anywhere and there's not really too much of a distortion problem, unless you're taking portraits. I would not reccomend this for portraits obviously.
This lens is very sturdy and I have yet to have a problem with it. Its my main lens for urban exploring which means it gets beat up a little every now and then, I've even dropped it on a side walk and its fine!
Only problem I've had with this lens is the hood, but oh well, you can just use your hand to fix light problems.
Hope this was helpful.
I would recommend this mainly for low light situations where you don't want to use flash, and its great for landscapes as well.
