I still have spent more on glass then I have on my first DSLR or my later upgrade. I have 4 lenses now, a 28-105, 100-300, and the 55-250 and 18-55 kit type image stabilized lenses that come with the various Canon packages.
The first two were excellent condition used ef lenses with 7 blade and usm focus motors, and the kit lenses actually take great shots for the money they cost. The stabilization really helps with many shots and they have great bokeh like your shots have if that's what it's called.
