Pairing speed and stellar optics, the Leica Summilux-M 90mm f/1.5 ASPH. is a fast portrait-length lens offering impressive subject separation using an especially shallow depth of field. The bright f/1.5 design is ideal for portraiture but also suits working in low-light conditions. Beyond the fast design, this 90mm f/1.5 is also distinguished by its advanced optical composition that incorporates a pair of aspherical elements to ensure high sharpness and low dispersion, and a floating element system is also employed to maintain consistent image quality throughout the focusing range from 3.3' to infinity. Additionally, this lens has an 11-blade diaphragm to produce an especially pleasing, rounded bokeh quality and a built-in lens hood helps to prevent lens flare and ghosting.

Short-telephoto 90mm focal length offers a flattering image quality that is well-suited to portraiture and mid-length images, especially when used in conjunction with the shallow depth of field afforded by the bright maximum aperture.

Two large-diameter aspherical elements are used to control spherical aberrations for improved sharpness and reduced distortion.

A floating element system is employed to maintain consistent image quality throughout the focusing range, even at the minimum focusing distance of 3.3'.

An 11-blade diaphragm produces a rounded and pleasing bokeh quality.

Built-in extendable lens hood shades and protects the front element to reduce lens flare and ghosting. Additionally, the front of the lens is threaded to accept 67mm screw-in filters.

Q: 1. Is an external viewfinder (a must (required) for this lens?

Q: 2. Hi. Just got the lens. New. Does the aperture ring, when opening at 1.4, does it goes a little further? Like if it had an extra stop?

A: The aperture ring can go a little beyond the f/1.4 clickstop, or a little beyond f/16 (or f/22) at the other end. Some lenses do this and others don't, depending on how the aperture ring is tensioned. It's nothing to be concerned about IMO.
