A short picture comparison from the 50mmm Zeiss Planar and the Apo Summicron(Camera & Photo“ target=“_blank“>Amazon).
The Apo Summicron costs about 10 times as much.
They are both shot with open aperture at F2. Both on a Leica SL body focused properly and with a shutter speed of 1/125s. No scientific test but should show how they compare in real world.
Can you see the difference in the low resolution pictures here?
Zeiss Planar 50mm f2 ZM at f2
Leica 50mm Apo Summicron M at F2
Probably nobody will see the difference here. The light is not very good of course.
