<p>You don't say whether full frame or crop. The 17-55 f/2.8 IS is good ("L" quality, say many) and I believe it is lighter than the 24-70.</p>

<p>The 40mm pancake lens perfectly matches your criterion of 'a different prime with a little more room'. You might also be able to pick up the old model (non-image-stabilized) 24mm or 28mm lens at a good price. Otherwise you can spend some more money and get the newer 24mm, 28mm, or 35mm lens.</p>

<p>Some older bodies are included in the offer, for example the 50D and the original 1D. These sell for a lot less than 400 pounds.</p>

<p>My bad - I'm not used to the US model numbers so I didn't realize an Elan 7e was not digital. (I see now it is called an EOS 30 in other markets.) In that case I am surprised to hear that the Sigma lens doesn't work with it - I guess the very last generation of film cameras also has the incompatible protocol change that came in with the 10D. But yes, a 28-80 zoom might be the cheapest option.</p>

<p>Jamie R, you are right, I didn't consider zoom lenses. Indeed there are plenty of 18-55 EF-S lenses for within the budget too.</p>

<p>Yes, I have the same lens (in fact I've tested two samples of it). Some folk have found a way to 'reprogram' these lenses using a programmable electronic device such as a Teensy and a bit of soldering - sorry I don't have the link to hand and I haven't had the time to try it myself. (It does work on film bodies and very old digital bodies: 1D, 1Ds, D60, D30, and those made by Kodak.)</p> <p>The question of whose 'fault' it is is futile, except to note you are certainly entitled to a refund from the camera shop if you want. A wide angle lens for under $100 is a tall order. You might, just, pick up a secondhand 40mm STM for that if you keep looking. Otherwise I suggest dropping the wide angle requirement and looking for a 50mm f/1.8. Increase the budget a little, and you might be able to get the now discontinued Canon 24mm or 28mm f/2.8 non-IS lenses. (There are manual focus wide angle lenses you can pick up for less than $100 including adaptor, but I can hardly recommend that as the first and only lens with your new camera.)</p>

<p>The 24-105 gives you image stabilization too. You already have a 20-35 lens (and not a bad one) so I suggest skip the 17-40 for now. Get the image stabilized lens and at some future point you can consider the recently announced 16-35 IS lens (or at least wait for it to drive down prices of the older 17-40).</p>
