Hi all,

I have a bit of a dilemma.

For my portrait and event photography ( events mostly indoors ) I am looking for a lens to replace my 18-55 mm IS ( the standard one )

I am thiniking to buy on of the below mentioned lenses.

Which one would you advise and why.

( the Canon 24-70 f/2.8 is sadly out of my price range )

Here are the lenses :

Sigma : 24-70 mm f/2.8
Tamron 28-75 mm f/2.8
Tamron 17-50 mm f/2.8

I am looking at the second hand market and the prices are almost the same for these lenses.

Thnx for you advise and tips
