negative:	- only APS-C - odd filter size of 67mm
comment:	Compared to my f2.8 and faster primes in the 17-50mm range, the Tamron performs great. Stopped down to f4 it beats both my 24mm and 28mm in sharpness. Performance wide-open is great for this relatively low priced zoom. The best standard-zoom for APS-C, imo. Only draw-back: not very useful on full-frame cameras.
