I wanted something in the bag that could reach out to 300mm, if it was too big to carry it probably wouldn’t be with me when I went out. Then I read about the Canon EF 70-300mm f/4.5-5.6 L DO IS USM.
Canon Pancake Lens
If you’re a photography newbie, or on a budget, this is a bargain! Sure, it’s not a zoom lens but you’ve got two feet for that…
