A great interior

This is the incredible interior of the Cathedral of the Saints Cyril and Methodius in Ljubljana, Slovenia. I shot this with my Sigma 14mm f/1.8 wide angle, and the settings were 1/40, f/2.5, and 3200. 1/40th of a second shutter speed is normally too slow for a guaranteed sharp picture, and this is definitely true when using a long lens. But with an extreme wide angle focal length, you can get away with it. Unlike a telephoto that bounces all over the place when holding it, there is no apparent movement when holding a wide angle lens. There is, of course, some movement, but it's miniscule and it becomes irrelevant. Virtually all cathedrals, palaces, and other historical places don't allow tripods. I bought the Sigma lens as an solution to that problem. The super large aperture means even in low light environments, I can shoot with a reasonable ISO and a shutter speed that addresses dark interiors well.
