Yeah, that looks the same. Same optics?

Pretty much.
So what did they do? Metal mount, better built. STM gear type drive (the slow STM type that the pancakes have), new coatings, new rounded 7 blades aperture design. Price still is low, at $129.99 MRSP.
So still the same ok-ish but nothing great bokeh rendering partly due to outlines in the OOF highlight circles. Still compact and very light weight (160 grams, up 30 compared to the old one). Will be interesting to see if the AF accuracy is much improved.
