When we use the Sigma 2.8/19 with Micro 4/3 cameras the flares appear in our frames only sporadically, just in very specific locations of the source of bright light. They become a bit more bothersome on stopping down because then you can see distinct streaks of light crossing the whole frame.
When you work with a bigger sensor, catching flares is much easier. Most likely it is due to a wider angle of view although a different distance between the rear element and the sensor and a different microlens array can influence such a performance as well. Anyway it is difficult to resist an impression that there are still more artifacts, they are easier to catch and the streaks, visible on photos, are somehow more intensive.
