Low light ability is the hallmark of a great 50mm lens. This shoot was done with my Canon EF 50mm f/1.2 L lens. Shot with 3 strobes – softbox in front and gelled to each side. The smoke was from a propane fogger with mineral oil. Taken just after sunset the light level in the wood was pretty low.
This is where the f/1.2 really shines – the light gathering is so high that you can see the so clear to compose and focus. As the evening went on to full darkness the f/1.2 lens continued to give great viewfinder performance.
