Over the past three months I have been debating selling my 24-70 f2.8 L. It's a huge lens that weighs quite a bit. Hauling it around has been not so pleasant. So I consulted a friend of mine who has both of them. He was very high on the performance of the f4. The fact that it also has IS was a big selling point along with the fact that it is a lot lighter. So I finally decided to purchase the lens. I use the 24-70 f2.8 L lens every day and carrying around this beast on my Canon 5D Mk3 was pretty heavy. Here are some of my first shots with the new 24-70 f4 L IS.
