www.dslrfilmnoob.com I don't recommend using zoom lenses for filming unless the zoom covers a focal length that is hard to find or not available. Two such focal lengths are covered by the Tokina 11-16mm f2.8 and the canon 16-35mm f2.8. I've already done a review on the tokina 11-16mm, but i thought it might be nice to compare the Canon 16-35mm f2.8 and the Tamron 17-50mm f2.8. The Tamron 17-50mm f2.8 is a budget zoom that you can pick up for around $450. http The Canon 16-35mm f2.8 is a ruffly twice that price: rcm.amazon.com The benefits of using a nicer Zoom can be seen in the full time manual focus, the longer travel of the focus ring, the stationary barrel, and the smooth operation of the zoom. These are all very nice to have but $500 in your pocket might help you forget about many of these short comings. Other zooms in my collection include the Tamron 28-75mm f2.8: rcm.amazon.com And the canon 24-70mm f2.8: rcm.amazon.com Although i don't generally use these last 2 lenses for filming, they are great for photography. If you must use a Zoom lens for filming make sure it is a constant F-stop across all focal lengths or your lens will automatically stop down as you zoom causing unwanted color changes and dimming of your video image.
