RECOMMENDATION

<p>I suggest you shoot with what you have for quite some time. Then you will be in a much better position to evaluate if you need something different.<br>

At a later stage you skills or expectations may outgrew your current hardware, or maybe not, but it's too early to worry about that.<br>

<p>Plenty of great choices offered here, and I'm a big fan of the "use what you have, and shoot" point of view, but we all buy new glass from time to time, and it's worthwhile to ask for opinions along the way. For a 50D (or any crop camera), the 17-55 f/2.8 IS lens is by far the most often used premium performance standard range lens in my kit. This shot shows my well used (dragged around the globe for almost 5 years) 17-55 on my current 50D. The same lens has painted the sensors of a series of cameras beginning with my first 30D with light, and it has never let me down along the way.</p>

<p>Again, there are many fine choices that you can make, and likely will make over time, but if I lost everything today, I would buy this lens first when I could afford to start rebuilding my kit. Everything else would fall into place over time...</p>

<p>I side with those suggesting you shoot with the 28-135 IS for a while before buying your next lens. It maybe all you ever want or need (oh if I were that lucky ). It is not very wide on a 50d, but that may not matter to you, or it could be of relative importance. That is your interests could evolve so that that you shoot enough wide angle you know you want to go top of the line or that a lesser cost lens will be fine and you would rather spend the money on a professional level telephoto, or a low light portrait lens.<br>

When I bought my first dslr I could not imagine having any use for a lens longer than about 135 mm. Now I spend a lot of time wishing for more than 400 mm. (problem is I am also wishing for wider than 17 on a full frame camera , a couple different fast primes, a fish eye...). My point is give it some time to see where you think you may be lacking and make additional buys based on your experience and tastes.</p>
