Review of the Voigtländer Nokton 40 mm f 1,2
Strongly Post Processed. Take a look at the geometry and the bokeh.
This is an unedited photo, straight out of the raw converter
In Post processing there has been applied a High-Pass- Filter, Blues and greens in the Shadows have been enhaned, as well as reds and yellows in the midtones. On the luminosity mask an S- curve has been applied and the contrast in the eyes has been globally increased
Sharpnes and micro- contrast
Review of the Zeiss Loxia 85 mm
This photo has been cropped slightly, to make the columns look straight and to crop some stuff on the right; it has been shot at f 2,4. Since the model has been moving, the focus is not perfectly on her face.
Pay attention to the incredible micro contrast and the rich tonality
85 mm is the ideal focal length to take portraits and at f 2,4 this lens has a very nice transition from in-focus-areas to out-of-focus areas even at f 2,8.
Some complain that the lens renders colors muted; others describe punchy colors. In my view, what some call muted colors might be the incredible way in which this lens renders skin colors.
The lens has god contrast and renders tonal transition very nicely
As you can see from the sample images, the lens is rather soft wide open. In my view, this is no disadvantage since the overall- look of the image is more balanced like that; the character of the photo becomes painterly, feminine dreamy. Like this, the transition from in- focus- areas to out- of- focus- areas is very harmonic.
On the second photo you can see that the bokeh balls are rendered egg shell shaped, even at the center of the image at open apperture . Yet, the overall quality of the bokeh is very pleasing.
The colors which are coming from this lens are saturated and punchy, which befits well the way this lens renders in general. The rendering of tonality, which is best seen in black and white is weak, when compared to other expensive lenses. You can get punchy black and white photos, but hey lack in microcontrast and richness in tonality.
Chromatic aberration can cause some problems, as you might expect from such a fast lens. Just be aware of it.
The construction of every lens is a trade- off. Since the Nocturnus is built for extreme speed, there are some downsides by definition. I actually do love this lens and it gave me fantastic images; even though, this lens has some weaknesses as well. Some of my most beloved images have been taken with this lens actually. It is fun to use and it gives you enormous artificial possibilities. I would never give this lens away anymore.
