"Cityscape shots are a little tricky because it’s tough to get a good overall image focus. In the shot above, I used my Canon 5D Mark III to dial in focus to get the best focus possible before taking the shot. After focusing, the only variable I couldn’t control was the wind, but for a 30 second exposure the result was okay – not great, but okay. (NOTE: The shot you see above is cropped and edited – click the image to see the out of camera original)
Once I have my settings dialed in, I switch to manual focus and use Live View at its maximum zoom to adjust my focus on items in the foreground and background to get the best balance of focus across the entire image. This is the greatest reason to use Live View in my opinion, so it’s automatic anytime I’m doing any shot that will allow me to use it (typically landscape or other static subject work).
For this to work my camera must be on a tripod and my subject must be static. The scene above of Seattle is a great test, so I took a few shots. While I’m not super happy with any of the shots I took due to wind, one of the huge problems I had during this test when comparing the Canon 5D Mark III against the Nikon D800 was the performance of the Live View on the D800.
Simply put, I found the Live View feature on the D800 to be unusable at maximum zoom under low light conditions like these. When I would zoom in with the Canon I’d get great detail and could easily dial in my focus on a detail like the people in top of the Space Needle. However, when I zoomed in with the Nikon all I could see was noise like you’d see on a old analog color TV. It was horrible and unusable..."
