Just for some comparison ...
Well, just to give you a lighting and IQ comparison, three shots. This uses the pop-up flash.
Dist: 1 foot (remember: 1-foot is not an option w/ T28-200 f/3.8-5.6 -> min focus dist. 6.9 ft w/o close up adapter)
The idea is to give you some idea of the brightness and sharpness differences between the apertures. Going wide does not mean you are going to have a good image, just brighter ... and usually softer.
DOF can have some widening if you give the lens some distance, but still, it's really, really tight under f/2.
