Remarkable image performance – the ZEISS Distagon T* 2,8/15 between sharpness and depth of field
The rapid development of image sensors for SLR cameras puts ever greater demands on the image performance of lenses. The resolution and contrast rendition of the optics have to keep pace with the higher megapixel values of the sensors to be able to take full advantage of their potential.
This makes the ZEISS Distagon T* 2,8/15 a solid investment for the future: its outstanding resolution power leaves plenty of room for future developments in the field of imaging sensors.
A landscape or overview image is a great way to reveal the performance of a high-quality super wide-angle lens, as Bertram Hönlinger from the ZEISS Customer Care Center demonstrates with this nice test image shot from the ZEISS building in Oberkochen, Germany: “Many small details, which are scattered across the entire image field, even into the edges of the 35-mm full frame, are rendered with high contrast and consistent sharpness in all regions of the image by the Distagon T* 2,8/15. The complex optical design of this lens, with its 15 lens elements in 12 groups, several aspheric optical surfaces and a total of five lenses made of special glass with anomalous partial dispersion, ensure that despite an extremely large angular field of 110 degrees (diagonal), there is consistent performance along the entire image field, without any visible longitudinal chromatic aberrations or lateral color aberrations, as well as a excellent contrast, even for the tiniest details.”
The strengths of the Distagon T* 2,8/15 in rendering rich details are not only clear to see in landscape images, but also in architectural images of interior spaces. For instance, Andreas Bogenschütz from the ZEISS Customer Support was not only able to capture the entire expanse of the church interior of the abbey church of Neresheim near Oberkochen in a single image. He also managed to photograph in sharpness the church’s ceiling fresco, with all its architectural details.
With an open aperture the Distagon T* 2,8/15 also delivers outstanding detail rendition, something independent testers also confirm (for example, Helge Hackbarth: “The ZEISS lens performs extremely well already at F2.8”). This opens up opportunities to experiment creatively with sharp and blur levels in the image.
The possibilities for creative composition also convinced nature photographer Filip Kulisev, who tested the Distagon T* 2,8/15 in Norway: “The Distagon T* 2,8/15 allows you to take very creative shots with unusual perspectives. Compared with other super wide-angle lenses, this one impresses me with its splendid focusing and outstanding image performance across the entire image field. Concerning the depth of field, I achieved particularly strong results with an f-stop of 7.1 for the range three meters to infinity. Overall, I was very pleased with the photographic possibilities of this new ZEISS lens.”
The community of ambitious ZEISS photographers is also enthusiastic about the photographic possibilities of the ZEISS Distagon T* 2,8/15, especially when the aim is to give an image real character without compromising on quality. Technical precision is and remains a source of inspiration when photographing with ZEISS. When Hans Daniels saw this airplane, formerly used by the Spanish air force, a number of terms crossed his mind that also made him think of the lens on his camera: reliable technology, vision, the innovations of the early days of aviation, discovering new things, acquiring new insights, capturing unimagined images: “The DC-3 Dakota stands in the midday sun, just like the situation before take-off. The deep shooting situation with the Distagon T* 2,8/15 on a full frame underlines this impression. The strong wide-angle perspective separated the majestic-looking airplane in its full width from the many other museum pieces surrounding it. The slightly asymmetric image and the tree in the background give the motif a heightened sense of tension.“
