Exceptionally bright wide-angle lens whose combination of large viewing angle and large opening opens up a multitude of creative design possibilities.

 

When the aperture is open, the 10 diaphragm blades produce a fine bokeh, which is not self-evident in the wide-angle range. The Ultron covers a diagonal angle of view of 91 degrees and offers a 50 cm minimum focusing distance.

 

The 1.8 / 21 mm is 78.4 millimeters long, weighs 412 grams and has a maximum diameter of 69 mm. The sun visor is permanently installed.
