Try using the built-in 1.3X crop on your D7100 (in the menu under "Image Area"), It will use the center of the image, best part/sharpest part through the lens. You go from a 24 X 16 to 18 x 12 mm image, drop to approx 15.3 MP, but lose no light in the process. It is a crop, but for a quick change in reach w/o having to change lenses, or adding a T/C, no light loss, so all functions work like they should. I like to fill the frame too, much like the big lens would allow, but if I don't have it with me, or will lose the shot due to the change, I simply push a button and rotate the wheel. A T/C will give a bigger image, but the added glass and light loss usually degrade past the point where a crop will still provide a fine image. Just something to try, that is already available, no cost.
Enjoy.
