I am looking for a new lens for photographing my 2 1/2 year old. Currently, I use a T3i with a 50 1.4. The lenses is great but I want some more flexibility in distance from the subject and an improved background blur that a longer focal length will provide. My daughter is quick and it foot zoom is getting harder and harder. A nice bokeh is important because I am not always shooting in the prettiest location.
So, I am looking for a quality zoom lens. My price point is $1500 or lower. I am looking to shoot indoors and out. Also, I do not plan on upgrading from a cropped sensor anytime soon but just in case my discretionary income increases, I would like to stay away from EF-S lenses for future upgrade possibilities.
Ideally, I would buy the 70-200 2.8L II IS but it is too far out of my price range.
The following lenses are what I have narrowed my selection down to but I am open to any other suggestions:
70-200 2.8L
70-200 4.0L IS
24-105 4.0L
Any thoughts on these lenses or recommendations of others?
Thanks everybody for your help.
