Which lens would be better?

Camera Body Cannon 400D (xTi)
Tamron 17-50 f/2.8 vs. Canon EF 28-105mm f/3.5-4.5 II USM

I understand the Tamron would be better indoor low light, but just curious on others opinions.

I voted for the Tamron, the F/2.8 is great

These two lenses do not have comparable focal length ranges and as such are designed for different purposes. It is impossible to choose unless we know the intended use.

Sorry... As I am new to this hobby. I had another post that had mentioned I was going to use the EF 28-105mm for sporting (Baseball) action shots. Mainly and outdoor useage.

I voted for the Tamron. Of the 2,it's the one I'd want. But Curtis is right, kinda like comparing apples to oranges.

Thats what I figured... Are the Tamrons build better than the Canon's?

Personally, I think 105mm isway too short to shoot anytype of sports, especially baseball. But of the two lenses, I'd definitley go for the longer one.

Are you shooting day time or night time baseball, or both? If you are doing anything in lower light, f/2.8 is a must.

I wouldn't go with the Tamron for your stated purpose, unless you are going to be standing on the field. I wouldn't even go for the 28-105 mm without being sure of being in the very front rows.

Or maybe I am not envisioning the kind of shots you are. I don't think 105 mm is going to let you have a player beating the tag at second base come close to filling the image. Not to mention any outfield action.

Most of it will be shots of the infield action and dugout shots for a traveling baseball team and high school team this year. I know I can't afford a lens to get the outfield.

I also found this at BH ( Tamron 28-80mm f/3.5-5.6 ) and ( 55-200mm f/4-5.6 Di-II LD ) Two Lens Kit for Canon Digital EOS Cameras. Both lenses together after the $30 dollar rebate comes to $169.00

Are these lenses resonable. Would the 55-200 get into the field more? As I stated I am new and I am not sure on how close the 55-200 will get in.

Thanks for any replies.

Ok ok ok... I am getting frustraded. I am getting good feed back but this is like trying to find a needle in a hay stack. This is what I have settled for. Will this work for shooting infield baseball action shots

Tamron Zoom Wide Angle-Telephoto AF 28-200mm Super Zoom f/3.8-5.6 XR Di Aspherical IF Macro Autofocus Lens for Canon EOS

Do you already have the XTi and lens, or are you starting from scratch? I would not recommend any of the 18-200, 28-300, superzooms. Too much of an optical compromise to get that much range in one package. Also, you probably find that 28mm is not wide enough on a 1.6 cropped body. Most people find that a 2 lens combo is better to cover that range. If this is your first dslr, I'd suggest getting it with the 18-55 kit lens. Good to learn on, and the 18mm will help alot on the wide end. If you want something in the telephoto area, take a look at the Sigma 70-300 for about $200. These two would give you a very useable range, and not break the bank. If you're new to all of this, I'd start off slow, not spend a fortune on lenses, untill you learn the camera, and develope your shooting style.

I'm not sure if this is a fair competition, but you can check photozone.de's review of both lenses.

I don't have the camera yet. Was wanting to buy the camera body and then a suitable lens for what I described. To me it seems more economical to buy the camera body $649 and a lens $299.00 (Tamron 28-200mm Super Zoom f/3.8-5.6) that I plan on using for the purpose I intend for it. Then have a kit lens that has been repeatedly put down (kit lens). With kit lens and the Tamron would be over $1200. Thats just my way of looking at it.

By all means, get whay YOU feel you need. Do remember that on the XTi, the 28-200 Tamron is going to act like a 35-320 lens (figuring in 1.6 crop). That is why most people recommend something wider then 28mm as a walkabout on a crop body. Doing a quick search, the kit I mentioned would be about $30 more then the one you mentioned, and give you more range. If you are dead set on a 1 lens solution, at least take a look at one of the 18-200mm superzooms, as it would give you the same on the long end, but more useable range on the wide. Good luck with your purchase.

The kit you mentioned? The Sigma... I can't find reviews on that one. Fredmiranda.com only shows the Sigma 70-200mm.
