<p>Viola, I bought this lens not so long ago for my canon eos 40d. regarding the focal length and aperture - it is a cheaper version of a fantastic 50/1.4 Sigma and the reason I didn't buy Sigma was the price. Now, if I was given the chance to take it back, I'd rather save up longer for a sigma, spend more and buy a better lens. Sigma has a better performance wide open than a Canon, let alone the built quality. The only issue, as always, might be the AF problem, as often is the case with Sigma lenses on Canon body.</p>

<p>Go for Canon or Sigma 50mm/1.4. They are considerably faster than your zoom (1.4 is twice as much light as 2.8) and on 1.6x body this focal length is already tight enough for portraits as it is 80mm. My Canon 50/1.4 USM with my 40D even at higher ISO speeds produces fantastic results.</p>
