ZERØ OPTIK Leica R 21mm f/4.0
(INSERT SINGLE HERO IMAGE HERE - other images below in media section)
Summary
Leica’s reputation was built on rangefinder cameras and lenses, but their SLR lenses were under-appreciated for decades before the cinematography community rediscovered them. Rather than prioritizing technical perfection, Leica’s engineers balanced performance with subtle aberrations to ensure beautiful and detailed images. Leica R primes offer smooth bokeh, warm colors, and striking dimensionality. Within the R series are multiple families of lenses; Summilux, Summicron, and Elmarit, and each has its charms. We are happy to help each client find the combination that suits them best.
