Canon announced two wide angle lenses in May and their list prices are surprisingly 'cheap.' The EF 16-35mm f/4L IS is what I am interested in. It comes with a 4 stop IS system and may find a place in my equipment bag once I have time to take it out for a thorough review.
You can see images taken with the EF-S 10-18mm f/4.5-5.6 IS and EF 16-35mm f/4L IS lens on Canon's China website. I am not enamored of the EF-S 10-18mm len's speed and will not be interested in this glass but it is available in camera stores now and you can see the video review here. The above video review is for the EF 16-35mm f/4L IS. I bring the EF 16-35mm f/2.8L on all my photo shoots. You can see photos taken with this lens on worldwide photo shoots on MichaelDanielHo.com
