nope, i only worked with the 105 (and the 70-300 "macro" but that isnt real macro) With animals in tanks (like fish or reptiles) i think your better of with the 105, since 150 is just to long. You can get the background in focus or you have to step back, which will give you a new problem. Cause you will most likely get reflection or glare from the flash in your photo. It depends on were the animals are in the tank, if they were close to the glass i would go and find another model. But it ranges from about 15cm too about 100cm for these pics. But i cropped the pics that were made from a longer distance.
And 105 is a good one for wild bugs too. You still have to get pretty close, but it it doable if you move slow.
All in all, im very happy with the lens :mrgreen:
