I was a little nervous buying a used lens, but the f/1.8 constant aperture across the whole 28-45mm range is exactly what I needed for indoor event shots, and it focuses fast on my Leica L body.

The glass is pristine despite the used listing, and the zoom ring has that buttery Art-series dampening that makes manual focus feel effortless. Pairing it with my L-mount body, the f/1.8 constant aperture at 45mm gives creamy backgrounds that I honestly didn't expect from a zoom.

The constant f/1.8 aperture across the whole zoom range is incredible for low-light shooting, and the build quality feels solid even for a used copy. The autofocus on my Leica L mount body is snappy and quiet, which is exactly what I needed for event work.
