I finally got to use my Canon 25-105 F/4 L Series Lens on My Canon 7D. It got heavy to carry after a while but it is fast and sharp. I really liked how it came out. All the movement was done by hand to mimic a steady cam. The focus is smooth. I am very happy with the lens in broad day light. This was my first Car show, I was impressed at all the various cars. The details and work that went into to them is incredible. I wanted to try to capture the curves, colors, and cool features of the cars.
