Default Sigma 18-250mm or Tamron 18-270mm??

I am looking at two different lenses for a Canon 7D. Which is the better option? The Sigma or Tamron? or just go with the Canon 18-200mm?

Any suggestions? Your input is greatly appreciated.

Thanks!

In my opinion, the Canon 7D is too good to be used with either of them. Superzoom lenses, even Canon's, aren't as good as multiple lenses of less ambitious zoom ranges.

Compare ...

Sigma 18-250mm f/3.5-6.3 DC OS HSM (Tested)
Tamron 18-270mm f/3.5-6.3 Di II VC LD Aspherical IF Macro AF (Tested)
Canon EF-S 18-200mm f/3.5-5.6 IS (Tested)

... with ...

Canon EF-S 18-55mm f/3.5-5.6 IS (Tested) and Canon EF 70-300mm f/4-5.6 IS USM (Tested)

What would be considered a good everyday walk around lens for the 7D? If you suggest that you stay away from superzooms.

Thanks

I'd say that the Canon EF-S 15-85mm f/3.5-5.6 IS USM (Tested) would be an excellent choice.

Hey Mr. TCav

Thanks again for all your help. I am kinda new to all of this and just want to understand about which lenses are worth getting and having a SUPER SHARP photo is very important to me.

I am looking at the Canon L 100-400mm and 28-300mm they are both very expensive of course 1699.00 and 2499.99. I was wondering between these two which is the better choice for baseball games, zoo, birds.

Thanks!

The Canon EF 24-105mm f/4L IS USM and Canon EF 100-400mm f/4.5-5.6L IS USM are both very good. The Canon EF 28-300mm f/3.5-5.6 USM L IS is also a good lens, but it won't be as good for birds, or baseball from the stands as the 100-400.

For birds the ef 100-400 L would be the much better lens. I tried shooting birds with a 300mm lens, and have found them to be way to short. The 400 would be the way to go, but the Bigma would be the best for birds.

18-55IS and 55-250 IS pair really well and is cheap compared to the L lenses. Performance wise they are a bit slow, but the image quality is definitely good.

Here is one more point, the 7D is a rapid fire canon. With what every lens you get, you will want a fast auto focusing lens. Something with a USM with canon, or HSM on sigma's. So you can take advantage of the fast burst rate.

That is one of the reason they match the ef 28-135 with the 7D. It really is a good lens, but can focus really fast. So you may want to opt for the 15-85 and the 70-300 with the 7D body. But it will be expensive.
