Decided that for my use the Sigma 150-500 is too long for the 7D as I almost always shoot handheld.
Choices to replace it are Sigma 100-300F4 or Canon 300F4L IS. Similar dollars, similar IQ
One of Sigmas best lenses
Its a zoom
Interested in peoples thoughts, particularly with the Sigma. Im leaning towards the Canon as with an Effective Focal length of 480mm the IS will be pretty handy.
