Latest Review Posted | Tamron Adaptall-2 SP (mirror) (06B) 350mm F5.6 Picked this lens up cheaply many years ago.Have a 500 f/8 and 300 f/4, so this focal length a bit redundant. Lens very slow compared to the bright 300 f/4, compactness advantage lost by more difficult focus. Opically, not as sharp as 300 f/4 glass, but considerably sharper than 500 f/8 Tamron. As mirror lenses go, it is very sharp and light /compact. Weight is not too much of an issue for me, so the 300 f/4 Pentax K rules (Tamron 300 f/2.8 weight is an issue though.) |
