It works out its money with interest, the stub really helps with hands at FR 100-150, it turns out to shoot at shutter speeds of 1/10., I would like a constant aperture, but this is a different price, AF is quiet, but not silent. sharpness at the edges almost does not fall, if it decreases noticeably evenly, which is natural for non-fixes. The picture is not expressive, a bit boring, but this is already nit-picking. Recommended for an entry level DSLR.
