Jos. Schneider & Co Kreuznach Xenar 105 mm f/ 4.5 Review
The lens is assembled in the Compur shutter, has 10 aperture blades. Minimum aperture - 32. Design is anastigmatic 4 elements in 3 groups (Tessar).
Schneider is known for its quality manufacturing optics. This lens is not an exception, it is made in the best traditions of the firm. I surprised its quality, sharpness, contrast, plastic. For the uncoated lens is a very good performance.
I mount it to the Nikon camera using the focusing helicoid. Also read How to Mount Large Format Lenses on DSLR Camera
Jos. Schneider & Co Kreuznach Xenar 105 mm f/ 4.5 Sample Photos
All photos are taken on the Nikon D3100, at wide open f/ 4,5. Tweaked levels in RAW converter.
Bokeh like Tessar
Color reproduction is good, but when shooting backlit, colors strongly distorted.
Pleasant soft effect for portraits
Example color distortion backlit, partly it happens when due correction contrast to the editor. It turns vintage color rendition, like Instagram filters.
Another example backlit. Contrast greatly loosened in RAW converter to bring the image back to normal. Chromatic aberration is not noticed.
Subjectively, I liked this lens. In comparison with other uncoated lenses has good quality.
