A cheaper lens will give you decent photos most of the time as long as:
-You stay away from either end of it's aperture range (better lenses will perform well even at maximum and minimum apertures)
-You stay away from harsh highlights as you will tend to get C.A. alot more than a better lens would
-You have room to crop the edges as there will be a greater tendency towards vignetting and lack of edge to edge sharpness with cheaper lenses.
-You don't mind a slower and likely more noisey focusing lens.
-You dont plan on doing print enlargements much past 11x14 as you will get less detail out of a cheaper lens.
There's other little niggles as well but you get the "picture"
