I currently have an XTi. I will be purchasing a 40D in a few months. For now, I am trying to create a decent Lens Line up.
Here is what I currently have.
#1 Canon Kit Lens - 18-55mm f3.5 - 5.6
#2 Canon 50mm 1.8
#3 Sigma 55-200 f4 - 5.6
#4 Canon 70-200mm f2.8L IS
I am considering buying one more lens to complete my lineup for weddings. I understand pros here consider only #4 to be of real value. S condering the crop bodies which one of the following should I get?
17-55mm 2.8 IS - Should I worry that I do not have the range covered between 55mm and 70mm? How important is that range now a days?
24-70mm 2.8L. With this choice I get an L lense and full coverage, but I lose wider angle and IS. How importance are the later two consider the difference between these two lenses?
One last thing, which lens would you use on which body of the two I mentioned.
Thanks.
