The Panasonic Lumix 24mm f/1.8 has been a long time coming. Pictures finally leaked to Nokishita this morning.
The lens is expected to have 12 elements in 11 groups, with 7 of those involving specialty materials or processes. It will have a 67mm filter thread and weigh 310 grams, befitting a soup can-style lens.
It is not expected to be cheap relative to competing f/1.8 aperture lenses.
