    Searched all over this forum and found a couple posts that said that they read that the new 18-55mm IS lens that comes with the XSi is better than the 18-55mm that comes as the Xt kit lens. Ok, so I have the 18-55mm kit lens that came with my Xt, is it worth spending $200 to get the newer lens with IS, or should I just use what I have?

    I am just wanting a basic walkaround lens. I am buying the 50mm f/1.8 as well, but plan on just using that for portraits mainly.

    If you could use IS then it might be worth it, but otherwise I doubt it's any better than the non IS versions in normal use.

    I just picked up an unwanted Nikon 18-55VR out of a D60 kit for $135 brand new never mounted and compared it to my 10x more expensive 17-55 f/2.8 pro lens and found that the VR is good enough that it makes up for its lack of speed and is equivalent for night time walkaround photography here

    If IS is really the only benefit, I'm not sure if it is worth it to me. I can't imagine that IS would make that much of a difference on this focal length.

    I don't think it would make a difference as long as you'd keep your shutter speed above 1/90 at maximum focal length.

    That's true...but with a lens that is F3.5-5.6, it's easier said than done.

    If the 18-55mm IS lens is only $200...I think that's probably a good deal.

    Nikon claims two stops, and I think Canon's is the same. I tested it out and it seems to be true. I can pull off 1 second handheld exposures with my 18-55VR at the 18mm end which is much better than the non-VR. At the 55mm end I can do about 1/4 or 1/5s vs maybe 1/15s or 1/20s at absolute best on the non-VR version. That's not a 50/50 sharp/blurred ratio either. I think I had to take 5 shots to get a sharp one at 1s on the VR lens. It's good enough that for available light walkaround photography I don't need to tote my massive 17-55/2.8 around anymore. Now if only Nikon's 17-55/2.8 had VR too. :grumpy:

    Well, I just found this where a guy posted two pictures. One taken with the kit lens, and one taken with the newer 18-55mm IS lens. He had this on a tripod, so IS was basically not used (unless his tripod sucks), and there is still a pretty good difference. It looks to me they put better glass in the new lens. I think I'm sold on it. Anyone want to buy my older kit lens ;) ?

    He said that he thought he might have had a bad copy of the non-IS, so you never know. Looks like his non-IS might have had a focus issue. Just because he focused on the same point doesn't mean it would focus the same. I wonder if he tried manually focusing to get better results?

    Both have same range, both have plastic mounts. Why not avoid all together and get xt vs xsi with a different lense?

    Don't get me wrong the 18-55mm is useful lense but I find it turtle slow without tripod or flash in low light.

    my $90.00 50mm lense gets used the most in all purposes. That and my 75-300. a good flash and photoshop help a lot with budgets.

    Getting an 85mm f/1.8.
