Mechanical Feel
The lens body is made of aviation aluminum with an anodized surface and has a good build quality.
With clicked aperture, you can switch it without looking at the lens, especially shooting at night.
The focus ring is designed to fit the finger, bringing a comfortable feel.
About Frameline
The focal length of the lens is 100mm, but because the Leica M camera does not have 100mm frameline, this lens is designed to trigger 90mm framing. (Ignore this if you are using an adapter to use this lens on a non-Leica M camera)
