I take a lot of pictures while on week long backpacking trips. Some of these include flowers, which probably are more close focus than macro. I used a Coolpix 5700 in the past, which had what I considered a very close focus, but I plan to take a D7000 this year with the 18-105mm lens. To keep weight down I would like to avoid taking another lens so I am considering a Kenko Auto Extension Tube, or maybe cropping the picture would be the best way to get what I want? Any thoughts?
This was handheld and maybe a tripod would have helped DOF, but I would like the option of the flower filling the frame and maybe a bit more DOF.
