IIThirteen blades
Light, givenshape.
Thirteen blades close from f/1.1 to f/16 in one unbroken curve, so every out-of-focus highlight stays round until the lens asks otherwise.
IIIFocus
Made to beturned.
Two hundred and seventy degrees of throw between 0.45 m and infinity, so a focus puller can land a mark by hand and feel it arrive.
IVOn set
Night, withoutdisguise.
Rain, a street of practicals and one figure walking out of the light. The kind of night this lens was drawn for.
VThe numbers
Nothing hidden,
nothing embellished.
