Sigma A 105 mm f/2.8 DG DN Macro

9. Ghosting and flares

Looking at the flat front element situated at the very end of the barrel and not sheltered from side light by anything, I started to wonder how the Sigma would perform against bright light. My worries were heightened by two more things: the complex optical system of the lens (as many as 24 air-to-glass surfaces) and inner focusing that limits to some extend the number of places where you can fix inner apertures to damp down flares. As you see the standards were raised very high indeed.

Photos below show clearly that indeed, the lens doesn't perform in an ideal way; still, taking into consideration the difficulty of the taks Sigma constructors had to deal with, it seems their instrument performs quite well. There are not so many reflections; only in one position of the sun (close to the frame corner) they become instensive but even then they don't occupy a lot of space in the frame.
