Above are three images shot with a Leica T (Typ 701) and the LEICA 35mm f/1.4 Summilux TL Lens wide open at f/1.4. Sharpness is excellent, bokeh is nice and not too 'artificial' looking and the lens has one interesting feature. The difference between the plane of focus and the out of focus areas is more marked than I've seen on any other lens. So correct focusing is absolutely essential.
There is some (very) slight CA / fringing wide open and (again very slight) vignetting at f/1.4 as well. Easily fixable, but it would have been nice if it wasn't there. Overall though, it's a seriously impressive performance. And, to be honest it would be a surprise if it wasn't. I personally don't use f/1.4 much, except in an emergency, but it's nice to know it's there if I need it.
Next post is on other narrower apertures and that is where this lens produces some quite amazing results.
