The 35mm F1.4 is known for his good sharpness, and its beautiful rendering of bokeh. I had the opportunity to try out one lens (and compare it to the Sigma ART 35mm F1.4). Unfortunately this lens showed significant blurring on the top-right side, hinting at a skewed internal lens element.
For the bookshelf, in the centre the lens is a bit soft at f1.4, starts to become reasonable sharp at f2.8 (bot not at the corners), and at f5.6 shows good overall sharpness. In the top-right corner there is quite some blurring, indicating an internal skewed lens element.

Similar observations as for the bookshelf.


The 35mm f1.4 shows an immense blurring problem at the (top-)right side of the lens. This is in line with other observations on the web, i.e. lens rental (“the variance is WITHIN a copy, not just copy-to-copy, none of the 10 copies we tested had even corners”), diglloyd and various forum topics, e.g. dpreview and fredmiranda (for a 55mm). Though the lens shows decent sharpness at f5.6, up to f2.8 this sample of the lens cannot impress me, and I don’t understand its huge price tag of €1699.
