Im looking for a 'walk-around' lens, one that I will take with me if I can only take one lens and use in general. It has to be small, but provide a good zoom range, and the 28-135mm seems good! However, I was wondering about the image quality - does the 28-135mm have better image quality than the kit lens? Do you think its worth it? I have a 55-250mm zoom lens which complements the kit lens well, but Im looking to upgrade that to the 70-300mm, and so the 28-135mm means I wont lose any focal length in-between the lens' Thanks in advance for any advice! EDIT: Im also looking at the 24-105mm which of course will be suerior in every single way to both lens mentioned, but the price puts me off a bit. I could afford it, but im 17 and going to uni soon so not to sure about it. If its 100% that I should go for that lens, then I may try and make some more money to buy it!
