Is the large price jump between the Canon 70-200 f/4 L USM and the version wth the Image Staberliser, the 70-200 f/4 IS USM, worth it?
Do I need it? How can one tell? Cost is an issue for me.
Iīd say, generally itīs worth it. However, if you work with subjects in motion (sports, running kids or animals), IS wonīt stop that kind of motion. For more static subjects (including people that donīt run or jump around all the time) in low light, it makes a world of difference.
