No internal focus, a fair degree of extension. The lens body has really been given a real shave, 372 grams. Retained olde worlde dots DOF display. The cine version's 16 blade aperture is intact.
The design is interesting - it's a beefed up remake of CV's 75/1.5 by the look of it, with the Sonnar style front end (four elements), followed by the now-common 'rouleaux' design layout featuring a central Summilux-style aspherical element, ending with four elements for back and forth correction, as two of them are the fine HRI elements DZO-Thypoch like so much. They did away with one ED element up front (no bad thing IMO) and carried on the correction throughout the design.
To get all that into 370 grams (just 20g more than the far simpler CV 75/1.5) is a fine outcome.
