Hi everyone,
I have a Canon XTi with 2 lenses. One is the 18-55mm and the other is the 70-300mm. I'm looking to purchase a lens that its int he middle of these 2 so I dont have to carry both of them when I dont need to.
I would like to which of these would be the best buy:
------------------------------------------------------------------------
1- Sigma 18-125mm f/3.5-5.6 DC IF Aspherical Zoom Lens at $242.00(Amazon)
2- Sigma 18-200mm f/3.5-6.3 DC Lens at $329.95(Amazon)
3- Tamron Autofocus 18-200mm f/3.5-6.3 XR Di II Macro Lens at $345.94(Amazon)
Thanks for the help. |

Hmm - I haven't used any of these, but I thought I'd mention that the Canon 28-135mm f/3.5-5.6 IS is only $409. Looks like the upper end of your price range, but if Canon brand and/or IS interesting to you...

have a look there
//www.photozone.de/8Reviews/index.html
"in the field the Tamron AF 18-200mm XR felt far more convincing than the Sigma AF 18-200mm DC"
I have the sigma 18-200. I bought for the same reason you mention, when I started with my rebel XT. Soon enough, I stopped using it. Simply too soft. |

Thanks Smurfguy, I will look in to it but i wanted something that would start at the 18mm. But still I will keep all options open.
Thanks again. |

The website that I find most useful when comparing lenses is
www.slrgear.com
I think they've tested all 3 lenses that you are considering. Check out the test page for each and make sure you click on the "Blur index" plot for each. Once you figure it out, it's very informative.
Edit: well, after skimming through those tests myself, it would seem that the best choice according to them is the Tamron 18-250 for around $470... The test page, including comparisons with the other lenses is here.

To be honest with you, none of those super zoom options are going to be very good for image quality or speed. I would highly reccommend the Tamron 28-75mm f/2.8 SP ($320-$350) instead of any of those. It would fit right in your range of lenses, it's also sharp and fast. The thing to remember is that the more the zoom, the worse the image quality. Which is why primes are the best.

Consider the tamron 24-135 3.5-5.6 SP, around $400.
It does macro and gets extremely high marks and ratings from everyone. I use it a lot for studio work and when I want a one lens walkround choice.

Given your budget, I agree with SamDoe1. But I also love the 18mm wide, and the 200mm reach, so it's tough. It's basically image quality vs. versatility - what's most important to you.
Cheers,
-Jeff

I used to own the sigma 18-125mm until it broke and got stuck at f8.
The focusing was a bit hit and miss but when it did get a good lock it was very sharp. It may focus better on your 400d than my 350d.

If you're going with Tamron (6 year warranty BTW), get the SP version. That's their top glass.
If SIGMA, get the EX version for the same reason.
My personal vote is for Tamron SP glass - I've been very pleased with them overall. |
