New Lens in Action
Here are the first shots with my new 50mm lens. I went to St. James Junction on Tuesday to shoot the Hudson Bay. I arrived on time but VIA did not. It turns out the engine crew were waiting for the doors to close, so I made a quick trip to A&W for lunch and returned just before the Hudson Bay crossed Waverley Street. I climbed to the top of the giant snow pile near the diamond to get some height, and took my shots.
VIA 693 had engines 6446 and 6413 on the head end, and the same Skyline (8511) that I saw a week before.
I am impressed by the clarity of the images. Granted, I had good light, but the details like the trucks on the engines really pop with this lens. However, there was one issue I had not anticipated.
I was surprised to see this "star" effect with the headlights. It is not specific to the lens but is due to a narrow aperture (in this case f/9.9). The technique is described here and here.
My other lenses did not show this because they are not capable of such a narrow aperture. The EF 50mm lens can use apertures from f/1.8 (widest) to f/16 (narrow), whereas my kit wide angle lens can go from f/3.5 to f/5.6. This is something I'm going to have to watch for! The good thing about using a narrow aperture is you get a wide depth of field, meaning more of the photo is in focus. If you're confused about aperture and depth of field, read this. I found it helpful.
The great thing about photography is there is always more to learn. I have a LOT to learn!
