The Leica Summilux 28mm f/1.4 is one of the best Leica wide angle lenses available. With only a 1.1% distortion the lens is sharp, fast and also smaller than it’s wider 21mm counterpart.

Using the Summilux 28mm f/1.4
Wide, fast and really minimal distortion, here’s some great uses for the 28mm
Not as wide as the 21mm but the 28mm makes for great landscapes shots. The fast aperture is also great for when night wants to come around and there is less and less light.
When it comes to Leica street photography lens, the 28mm takes the cake. 28mm is THE focal length that street photographers gravitate to and the 1.4 makes it particularly suited for street portraiture.
Since this is more portable than the larger 21mm, this makes a great all around travel lens, the fast speeds are good for day and night and the focal length is perfect to get in those travelscapes, environmental portraits and more
It is a myth that wide angle lenses can’t blur the background. With full frame and a fast lens, you can. So yes the 28mm can bokeh real well and blur the background and makes it possible to do great environmental portraits with silky smooth bokeh.
Distortion vs focal length. This is a better lens for distortion vs the 21mm (1.1% vs 2.3%) but it is a less wide lens. The distortion is minimal so only if you are doing technical architectural work should this be a deciding factor.
