A trip to the zoo is always fun...
I wasn't sure about lugging the heavy lens around on our visit to a zoo while on Spring Break, but am sooo glad I did. The iPhone trumps the full-frame DSLR in low light situations, such as in the dark halls of the aquarium portion and the feeding of the penguins, but the details I captured and angles I wasn't able to capture on our last visit are priceless...
