Hi I just recently got a Canon XS (my first DSLR) and have been playing a little with the kit lens and I really like it.
I want to get a sencond lens that gives me more range. My budget for a new one is around $250 but I would like to keep it under $200.
I am considering the Canon EF 75-300mm f/4-5.6 III USM for $192 (or $160 for the non USM version).
Now the Canon EF-S 55-250mm IS cost a little more ($255) but I am trading 50mm for IS.
Are these similar lenses? Am I better off with IS over the extra 50mm?
Before anyone suggest to get an L lens,keep in mind that my wife and I have other financial priorities (want to build our house soon). Eventualy one day I might get one but now I just want something to learn and take better photographs.
Get the 55-250. It is not the "best" lens out there, but the next logical step from the 55-250 -- that is a lens with almost as much zoom and with IS, but significantly better IQ -- is the 70-200 f4 IS which is $1000! There is a 70-300 IS USM in the middle as a nice option, but is about twice as much (around $550+) and isn't TREMENDOUSLY better, though it is sharper. Also, 70mm on the short end can be a problem. 55mm is long as it is. Stay away from the 75-300 lenses. They are junk.
The 55-250 is a great lens, when you factor in cost and weight. Yes, it's slow (f/4.-5.6), so it's not an indoor lens, but outside it's fine. No, it's not the sharpest, but in lenses covering that much zoom, there are none sharper under $400. Primes are sharper, but not as versatile.
The 55-250 benefits from some post processing, as it lacks a little contrast, especially at the long end. It also has some vignetting, but I rather like that look.
Things you can do with the 55-250 that you might not think about:
1) Outdoor portraits: formal or candid. When you push the zoom out to 250, you can get fantastic people shots. And, if the background behind the person is far enough away, it will REALLY blur out nicely. The bokeh on the 55-250 is actually quite nice, and it has great aperture blades , so bright sources of light in the blurred background round out nicely. (This lens has 7 rounded blades -- some of the cheap primes people brag on actually have sub-standard bokeh because the apertures are old design and only have 5 blades, so blurred points of light look like hexagons. Also, you can get more background blur with the 55-250 at full zoom at f/5.6 with a headshot than with the 50/1.8 on f/1.8 -- I've had both, and I know it to be fact). The other incidental nicety here is because the lens is a little soft, the pictures of people look great. You don't see every pore in their skin as clear as day. You will get MUCH better portrait shots with this lens at the long end than you can with the kit lens. Much better. Did I mention much better? The vignetting on this lens also adds nicely to the portrait effect. Using this lens for portraits has got me hooked on portrait shots. I think it's now my favorite type of picture. Here's an indoor sample (not mine):

2) Flower shots (or other "macro-like" work). The 55-250 is NOT a macro lens, and has a minimum focus distance of 3.3 feet (so, your subject has to be at least 3.3 feet away to get focus), but as with the portrait, the background can be blurred out quite nicely, and the subject isolated. The 70-300 has a longer MFD (5 feet!) and doesn't magnify as much. Using this lens in this way has got me into macros, and now I'm shopping for a Macro lens. Here's an example (not mine):

3) Sports. No pro sports, but fun snaps. The auto focus (AF) is fast enough for mild sports. I shot great pics at a marathon, my young kids soccer game, etc. With some intelligence, you can get other and faster sports, too. When I said the 70-300 is a little too long on the short end, I was thinking specifically this. When I'm on the side lines of my kids' sports, I can get good up-close pictures with 55mm. 70mm is just that much harder to work. (OK, you probably considered sports already, but I wanted to put in my two cents worth). Here's a sample (not mine):

Will you be happy for ever and ever with the 55-250? Probably not, at least not if you tends towards perfectionism. But it takes good shots, and on a budget is a great lens. You can see samples on POTN here:
http://photography-on-the.net/forum/showthread.php?t=459569. This lens is so well known, it's got a nickname "nifty two-fifty." Look through these threads and see the sample images. Very versatile lens.

Last comment -- don't waste your money on the 75-300 options. Also, you do NOT want to be at these focal lengths without IS unless you are in full daylight. And even then, IS is nice to have just to steady the image for framing.
Hey -- do you want to buy mine? I've got to scrape up enough to get the 70-200 f4IS! No, just kidding. I WOULD move to the 70-200 f4IS if I had the cash. That lens is incredibly sharp (sharper than many, though not all, prime lenses), and is a stop brighter at full tele, but it's out of the price range at the moment. In case it makes a difference: I currently have the Sigma 18-50 f/2.8, the Canon 35/2 (had the Canon 18-55IS and the Canon 50/1.8, but sold them both) and also the 55-250. The 55-250 is by far my most fun lens. I'd like the same thing, only sharper and bit more contrasty, but it just doesn't exist at this price point.
