Danielle,

There is more than one way to skin this cat and it important since the difference in focal length is so small.

First might be an extension tube or even two; these allow macro use, closer focus, on any lens in this system.

Second is a shorter lens which can focus closer normally, if that's what your really looking for.

Given that all the lenes available for this system with the possible exception of the 50 are really great; my thought is that a such a small change, 127 to 140, will not result in a truly meaningful difference.
