Build quality is impressive. The texture and finish is different than Pentax manual lenses I've used, but it's very well put together. The aperture ring clicks nicely, and the focus ring is well dampened (a bit much for my linking actually ). It renders pleasantly wide open, not super sharp but enough for my needs and with nothing offensive, just overall lower contrast and some softness, perfect for low light night shots. It gets rather sharp around f8.
