ELMARIT-S 45 f/2.8 ASPH. CS

The high-performance standard wide angle


A classic in absolute perfection


The Elmarit-S 45 f/2.8 ASPH. (CS) (35 mm in 35 mm format) is as outstanding for landscapes and architectural photography as it is for studio work, with its moderately wide-angle characteristics but simultaneously true-to-life perspectives.


Its extremely elaborate construction, designed to deliver maximum contrast at maximum aperture and at the shortest focusing distance, ensures that the lens is practically free of aberrations.


Monochromatic aberration is almost nonexistent and chromatic aberrations are corrected to an absolute minimum.


The Elmarit-S 45 f/2.8 ASPH. (CS) is also available with a built-in central shutter.


The highlights

For an enormous range of photographic situations


Corresponds to the angle of view of a 35 mm lens in 35 mm format

Innovative central shutterfor maximum design freedom when using additional light

Excellent imaging performance over the entire range and at all aperture settings

Extremely fast

Creative use of sharpness and blurring for the plastic extraction of motif details

Best image quality up to the edges due to aspherical optics

Weather- and dust-sealed lens


Technical Details


Three of the twelve lens elements are manufactured from glasses with anomalous partial dispersion for the minimization of chromatic aberration and two others from high-refractive-index glasses with exceptionally low dispersion.


In addition to these, one aspherical surface is employed for the minimization of monochromatic aberrations. Rear-group focusing guarantees consistently outstanding imaging properties from infinity to the closest focusing distance.


Modulation Transfer Function


The MTF is indicated both at full aperture and at f/5.6 and f/8 at long taking distances (infinity).


Shown is the contrast in percentage for 5, 10, 20 and 40 lp/mm across the height of the 35mm film format, for tangential (dotted line) and sagittal (solid line) structures, in white light. The 5 and 10 lp/mm will give an indication regarding the contrast ratio for large object structures. The 20 and 40 lp/mm records the resolution of finer and finest object structures.


Distortion & vignetting


Distortion is the deviation of the real image height (in the picture) from the ideal image height. The relative distortion is the percentage deviation. The ideal image height results from the object height and the magnification. The image height of 27.04mm is the radial distance between the edge and the middle of the image field for the format 30mm×45mm.
