Leica R primes are well known for their quality and character. They deliver images that are sharp and well-corrected, but still very flattering on your subject, and they flare beautifully. A major selling point is that due to the complete redesign of the lens, all the lenses have an improved close focus. The 50mm T0.95 'Noctilux' has consistently been a technical marvel and a lens that many photographers put on a pedestal. While it's meant to provide a more glorious, heavenly look whilst wide open, contrast and resolution do clean up significantly when stopped down.
