Originally posted by northcoastgreg If you are dissatisfied with what you are getting with the 18-55 and that lens covers your most used focal lengths, then sell the 55-300 and get the 16-45. There's no point in condemning yourself to unsatisfactory IQ in the focal ranges you use most, merely to retain satisfactory IQ in ranges you use less often. Instead of saving for a 16-45, perhaps it would be wiser to get the 16-45 and save up for the replacement(s) of the 55-300.
This is true. There are also inexpensive 55 - 100mm primes on the market (all manual) that would serve as a portrait lens.
Another option I might suggest is the excellent F 70-210, often available for about 100 dollars. It is not as long as the 55-300 (or as fast at 200mm) but it is a pretty good portrait lens in a pinch (very sharp wide open, pretty good bokeh for a consumer zoom, good contrast / colours).
Better options exist but its a good lens for the money.
