<span style="font-size: x-small; font-family: trebuchet ms,geneva;"]<span style="color: #333399;"]I'm a mum who likes to take pictures of my child.
<span style="font-size: x-small; font-family: trebuchet ms,geneva;"]<span style="color: #333399;"]I'm presently using a Canon 500D with the kit lens EF-S18-55mm f/3.5-5.6 IS.
<span style="font-size: x-small; font-family: trebuchet ms,geneva;"]<span style="color: #333399;"]I am looking for something that has bigger aperture that allow more lights into the camera? Basically I need a lens that is fast that is able to capture the fast movement of young children, especially for indoors situation.
<span style="font-size: x-small; font-family: trebuchet ms,geneva;"]<span style="color: #333399;"]I was browing around the Canon website.. EF-S17-85mm f/2.8 IS USM & EF17-40mm f/4L USM are within my budget.
<span style="font-size: x-small; font-family: trebuchet ms,geneva;"]<span style="color: #333399;"]May I have some suggestions on which is a better choice for my purpose? Or if you have any other suggested lens.
<span style="font-size: x-small; font-family: trebuchet ms,geneva;"]<span style="color: #333399;"]Thanks!
