Certainly, manufacturing is light: if it falls, it breaks for sure. But the picture quality achieved is breathtaking! In APS-C it becomes a 80mm: excellent for portrait (bust) but not only. I recommend adding a filter because the focus ring is beveled and adjoins the lens, so that during the manual focus was quick to touch the lens. With the Canon filter - Filter - protection - 52 mm - F52REG you get more comfortable with this not very wide ring and no compatibility problem with the lens hood Canon ES-62 - Lens hood and cap (which can set in addition to the filter).
