I am a frequent macro shooter and I have the specialised gear for that but with a 28-105 (still my favourite walk around lens) you can do very nice things related to close-up photography, and have fun...
Take care, all these pictures have been taken handhold. If you put this combo on a tripod, eventually more perfect with shutter delay or remote control, the results will be even better...







I consider the 28/-105 still as a very good lens on FX Nikon bodies because of good sharpness, very low distortion, nice focal range, close up mode, compactness, weight and size.
Thanks for looking
