Hey there. I'm a newbie to photography and this forum. I currently have a Canon T3i with the 18-55 mm kit lens and the 55-250 kit lens as well. I was looking for some opinions on what lens to invest in next. I will be shooting mainly portraits, family portraits and kids. The price doesn't matter too much as I don't mind spending money on something that will give me sharper pictures. Thanks for any opinions!
