When Canon announced that they would be charging a whopping $2300 for the mk2 version of their 24-70 f/2.8 L lens, and that it would not contain image stabilization, most Canon users were mighty perplexed. It didn’t help that Tamron had just announced a stabilized 24-70 f/2.8 the day before Canon’s official press release. Kind of a slap in the face for many people who were expecting stabilization especially for such a high price. Also, the previous version of Canon’s 24-70 f/2.8 was no slouch, really. It wasn’t perfect, but then again you could find one used for $1250!
