The Sonnar 2/85 drastically changes its depiction depending on the combination of aperture and exposure. When it’s used wide open, it’s soft and produces halo. At f2.8, the softness is gone, but there’s still some halo. Then at smaller apertures, it becomes clear. It shows an interesting change according to the exposure, too. If it’s used under, it produces thick depiction with deep color and high contrast as you expect from Zeiss lenses. If it’s used over, it produces very soft and gentle image with lower contrast. If you keep these traits in mind, you can deal with a variety of situations. On the other hand, you may end up being swayed by this lens until you learn the traits. However, if you are careful with light, aperture, and exposure, this lens will provide you with higher image quality. If you take a portrait of your loved one, shoot over (+2/3 to +1 overriding to what the camera tells) against the sun with an aperture of f2-2.8. It will get his/her fantastic smile wrapped up by the gentle light. Or, if you shoot a back street on a cloudy day in Europe, use the aperture of f2.8-5.6 and shoot under (-1 overriding). The stone pavement will emerge in the deep hue. The Sonnar 2/85 may force you to use in an older manner and that may be challenging. But, the challenge will be rewarded and it will bring a renovation to a photographer.
