Description
Note: this is a 50% crop of the original photo, since bird was to small on the orginal image, it was taken at an distance of about 4,5 meter. (see full view)

visiting juvenile magpie again, was taken on the front lawn with a Manual focus Leitz Elmarit F2,8 180mm at full lens opening.

F2.8/180, Elmarit-R II, 1978 > 1997. [link]

"This redesign is reduced in weight through the use of newer glass of anomalous dispersion and other measures for weight reduction.
At full aperture the lens delivers medium contrast and coarse detail is rendered with clean edges over the whole image area, with the corners being even better than the centre. Overall the performance is equal to that of the replacement lens.
Stopping down to 1:4 improves the contrast, but brings only marginal better definition of fine detail.
From1:4, image quality does improve very slowly, with an improved definition of very fine detail on axis and a reduction of contrast in the field."

"This lens has also improved performance at closer distances. The improvement in image quality has been made possible by a reduction of lateral chromatic errors and the chromatic
version of astigmatism, which points already in the direction of the apochromat." (Erwin Puts)
