<p>Thanks for your responses. regarding the most often used focal length, I would say it has be between 22-40mm (landscapes) the most and aperture has kept varying depending on the shot because I never had a constant aperture to being with until I bought the tamron and even after buying it I keep using the kit lens more for its wide angle range.<br> The reviews metrics wont help me much as they all come out close together in numbers and finally what dominates in a photo is the composition and lighting more than those numbers.</p>

<p>Hi,<br> I have a Canon Rebel camera and have been using it with the kit lens for over 6 years but over the period I have added on to my lens collection. Now for the most used wide angle range I have the 18-55 kit lens and also have the Tamron28-75 f2.8 which is a fantastic lens. I have been thinking of replacing my kit lens with a better lens and I am considering the Sigma 17-70 f2.8-4 C lens which has got has the good useful range and with the big aperture at wide angle. I am hoping this single lens will replace both my 18-55 and the 28-75.<br> But I am a little confused now because 28-75 with constant 2.8 is an excellent lens and think the new lens might not do so well in this range.<br> Am I better of going for a 17-50 f2.8 Sigma one so that I get the benefit of f2.8 through out, or does the advantage of having one lens to carry more than compensate for the loss in aperture?<br> Please share your feedback.</p> <p>Thanks,<br> Hemanth</p>
