Today’s photos leave no doubt about that I’m on the road, means on a business trip. On the flight from Chicago to Los Angeles yesterday I saw some nice cloud formations, had a glimpse into the Grand Canyon, and finally an unobstructed view over the skyline of Los Angeles. I really like to use these travel opportunities to improve my skills and to experiment with the lenses that are in my bag. This time the wide angle SIGMA 10-20, f/4-5.6 DC HSM was on the camera most of the time. I have this DX lens since quite a long time but still have the feeling that I don’t ”own” this lens because I haven’t dug deep enough to know all it’s capabilities. This year’s vacation trip is coming up soon and I plan to make the 10-20 an essential piece in my landscape photography tool box this time…
