The elaborate lens design, comprising 19 elements in 15 groups, ensures an outstanding optical performance. A total of three elements feature aspherical surfaces on both sides. Nine specialist-glass elements with anomalous partial dispersion provide excellent chromatic correction across the entire focal range. The internal focus is based on a single, light-weight lens element, and utilizes a quiet stepper motor to deliver a fast and precise autofocus. With it robust metal body and ingress protection against water spray and dust, the Vario-Elmarit-SL 24-70 f/2.8 ASPH can even be used in harsh environmental conditions.
The compact dimensions of the Vario-Elmarit-SL 24-70 f/2.8 ASHP are made possible by the absence of in-lens optical image stabilization. When the lens is mounted on the SL2 or SL2-S, the camera’s suspended image sensor provides highly effective image stabilization. This applies equally to still photography and video recordings. The aperture of the Vario-Elmarit-SL 24-70 f/2.8 ASHP comprises of 11 blades – facilitating a harmonious, circular bokeh. The minimum focusing distance is just 18 centimeters from the sensor plane (at the shortest focal length) and 38 centimeters (at the longest focal length) ensures exceptionally high-quality images even when shooting at close range.
