Leica Summilux-M 28mm f/1.4 ASPH review
With a maximum aperture of f/1.4 Leica’s new 28mm Summilux for the M system offers that magic combination of wide angles and shallow depth of field. Damien Demolder tests it
Leica Summilux-M 28mm f/1.4 ASPH review: Features
Making wide aperture wideangle lenses isn’t easy, and this model needs a total of ten elements grouped into seven clusters to make it work. The final element of the construction is aspherical, while seven others use glass with anomalous partial dispersion to ensure colours focus in the same plane.
Leica has also used what it describes as a floating element directly behind the iris, which it says is used to ‘maintain performance’ in shorter focusing distances. The element is ‘floating’ because it moves independently of the main focusing group.
The diagonal angle of view is 75° on the company’s full-frame cameras, though M8 users will get 60° and the look and feel of a 37mm focal length.
Closest focus for the lens is 0.7m, though with a small aperture and the resultant depth of field, objects closer than that can appear sharp. As usual, distances marked in feet are coloured yellow on the focusing barrel, and those in metres are in white. The aperture ring offers settings from f/1.4 to f/16, with half-stop clicks in between. There is a depth of field scale marked on the ring closest to the body of the camera, and at the other end of the barrel a very nice metal lens hood screws into a thread around the outside of the barrel, while a E49 thread is provided for screw-in filters.
