	Patchin, what camera body are you using this lens on?
	
	I do not have any personal experience with the Tamron 60 mm macro.  Speaking solely from a "focal length" point of view however, 60 mm is a very capable FL to work with.  Granted, it will not provide you the same magnification as a 90, 100, or 105 mm, you can still do plenty with 60 mm.  And if you can't get close enough, cropping is a solution for some.
	
	If you have never tried macro photography, I might suggest keeping your new lens for a little bit, and shooting around with it.  See if macro photography is really something you would want to invest more in.  Some people may advise otherwise -and just ditch the 60 mm, and leap for something in the 90-105 range, and that is fine too.  It is really your call.  Though, I might also add that you don't have much to lose by keeping it for a little bit, and giving it a little play time.
	
	Also, consider what you may be using the lens for other than macro photography.  "Macro" lenses can be used for everyday picture taking, simply treat them as a regular prime lens.  Personally, I don't use my macro for anything but macro work because 100 mm is too long a FL for me.  I'd rather use the 60 mm FL for everyday shooting.  Again, that is me.
	Just something to consider.
