The 50/1.5 C-Sonnar is a classic design favored by some for portraits and its dreamy look when shot in the f/1.5 - f/2 range, as well as its classic (historical) look long appreciated in photography.
The compact design is characterized by uncorrected spherical aberration resulting in some focus shift, as well as wave-type field curvature. This is not a lens to look technically excellent, but rather one that offers unsual artistic qualities.
Use if this lens must be learned: its focusing characteristics (eg focus shift) can result in soft images if not understood! Get it only if you understand these issues; it’s an artists lens that takes some skill and appreciation to use well.
Not yet tested.
The T* coatings and 6 elements promise outstanding flare control.
NuGard KX Case for iPhones and iPads.
Outstanding protection against drops and impact!
Plus, excellent grip for wet hands, cycling, etc.

The wave distortion is mostly pincushion, reversing to barrel distortion near frame edges.
However, the total distortion is only about 0.5%, unsually low for a 50mm lens, and thus likely to go unnoticed with the majority of images.
