Appreciably wider aperture
1.8 vs 2 —11.11% wider aperture. Aperture sizes are expressed in f-stops. The smaller the number, the wider the aperture. This means the sensor captures more light, helping to avoid blur by enabling you to use a faster shutter speed. In addition, a wide aperture provides a narrow depth of field enabling you to focus on the subject and blur the background.
6.9 mm vs 8.5 mm—1.60 mm thinner
