I got the silver one. It looks very similar to the 35 Ultron but less tapered. Not sure why they felt the need to add the silver base to the black version. I guess someone at Cosina hates all black lens. First impression is quite positive. Sharpness, color, rendering, all good. No focus shift. Build quality is about the same as the 28 Skopar, good but not amazing. Mine only came with the pinch style lens cap. Only negative is the vignette is quite strong, still visible at f8.
