Ah, 49mm a bit small and 40 cm diopter works out to 2.5 diopters— usually too 
strong for longer FL’s and working distance a tad short for shy critters.  You 
would like one larger and less powered for the longer zoom.   I predict you 
would love it.  I have 3 for very specific tasks but Moose has so many he 
requires a spread sheet for achromatic diopters!   There is no guarantee the 
optics will mesh well though.   They don’t require a major investment so the 
worst case scenario is far from fearsome.
