For an everyday walkabout lens, which of these two would be the better replacement lens for the Canon Kit lens?

I have the Rebel Xsi/450D and have a number of other (cheap lenses). I've also read the newer batches of Tamron VC models have rectified a problem with the earlier release.

Many thanks in advance.

If you need 70mm and OS, Sigma 17-70 OS HSM.

If you need constant 2.8 and OS, Sigma 17-50 OS HSM.

If you need constant 2.8 only, Tamron 17-50.

Figure out what you need and worry about IQ next.

If you don't care about wide end, want more reach and need OS, 24-105L would be ideal.

LOL !
Both the Sigma and Tamron are sharper and cheaper than the 24-105 on a crop

But it is true, if you need OS and more focal range the Sigma 17-70 is better, the Tamron 17-50 2.8 non-vc is sharper at f2.8

The Sigma is more of a general walk around than the Tamron. I'm a huge fan of the Tamron for sharpness and color straight out of the camera but the wider range of the Sigma and the OS makes it more versatile by default.
Don't discount the Tamron 17-50 VC. It got a well deserved bad rap for being soft when it was first released, but after the first runs, users report the VC is sharp wide open. Sigmas 17-50 OS is supposed to be a very good lens as well with constant 2.8

For 17-50OS, No real good reason to go with Tamron instead of Sigma since it's nearly the same price. Plus Sigma has HSM. It's a much quieter autofocus motor. Not much quicker though since Sigma 17-50OS has a micro-motor HSM instead of true ring HSM.

When I had a 50D, 24-105L was the camera 80% of the time. I just don't like wide shot that much.

Advice to OP is this:
1) Figure out what FL range that fits you best
2) Buy the right lens instead of chasing the lens for IQ reputation

I ordered the 17-70 OS, it will be here tomorrow, after a lot of consideration. I have been using the 28-135 that came with my 50D since I got it, and I started to crave wider. I wanted to get the 17-50 OS but I already have a few 72mm filters, and to replace them was not financially feasible for me.

Right now my 28-135 is my longest lens and I'm not planning on selling until I get a new telephoto.

You will find a lot of people on this forum with the Sigma 17-70 OS. I've had one for over a year, and it is my main lens. Sharp, with macro capabilities (1:2.7), lightweight, and now under $400 - you cannot go wrong with it.

The 17-70mm OS is a good lens, if you get a copy with decentering problems exchange it or send it to Sigma for repair (probably exchange it for another copy).

Nice things about the 17-70: Nice bokeh oh long end, sharp all around if you have a decent copy. My girlfriend has a copy of it, it's good but seems to have a few decentering issues, thinking I might send it in to Sigma (she uses a 17-55mm IS at this point). It also has a GREAT (for a regular zoom) macro mode.

I think thats about the best answer right there.

I chose the 17-70 OS because I wanted the extra 20mm and OS. I am VERY happy with my choice.

Thank you all for your replies.

The Tamron I was thinking of is the 17-50 f2.8 VC (as I have read the updated version has fixed the previous problem).

To add to the mix what about the Sigma 18-50 f2.8?

Sigma 18-50 is not quite as sharp as tamron 17-50 non vc.

Tamron 17-50 non vc is the best bargain if you can live w a loud af motor and non vc. It also hunts a bit in low light.

Otherwise sigma 17-50 OS is the next step up. Even micro motor hsm is still nicer than tamron 17-50 vc af motor.
