How does the Canon EF 50mm f/1.8 STM perform in low-light conditions

1. Wide maximum aperture: With a maximum aperture of f/1.8, this lens allows much more light to reach the camera sensor compared to kit lenses that typically have maximum apertures of f/3.5-5.6[1][4]. This enables shooting in darker environments without having to raise ISO or slow down shutter speed as much.

2. Light gathering ability: The f/1.8 aperture gathers about 4 times more light than an f/3.5 aperture and 8 times more light than an f/5.6 aperture[1]. This translates to much better low-light performance.

3. Faster shutter speeds: The wider aperture allows for faster shutter speeds in low light, helping to reduce motion blur. For example, a shot that might require 1/20s at f/5.6 could be taken at 1/160s or faster at f/1.8[1].

4. Image quality: The lens can produce better image quality in low light due to the ability to use lower ISO settings, resulting in less noise[4].

5. Depth of field control: The wide aperture also allows for a shallow depth of field, which can be beneficial for isolating subjects in low-light environments[4].

6. Versatility: Users report being able to experiment with shooting at different times of day, including darker conditions, without as much concern about available light[4].

Overall, the Canon EF 50mm f/1.8 STM is considered to make a "wild difference in low light performance" compared to kit lenses, significantly expanding the shooting possibilities in challenging lighting conditions[1][4][5].
