Canon 50mm f/1.8 STM VS 24mm f/2.8? I've been thinking about purchasing one of these lenses. I understand that the 50mm is perfect for portraits and has an amazing background blur effect. However, it's a long length and it would be hard for landscape/street photograph which is something 24mm would be better at.When mounted on a Canon EOS 5D Mark II, it rates among the top seven standard prime lenses (with a focal range between 35mm and 85mm) achieving an overall DxOMark Score of 26. Strengths of the Canon EF 40mm f/2.8 STM include resolution, as evidenced by its Sharpness score of 15P- Mpix. Additionally, our sharpness measurements and field maps GLMYE.
