That lugging around of the Macro 100 lens (plus tripod!) is indeed off-putting. Your results are indeed better than what I managed to do with the pro lens! Especially the flexibility you must now have could make the difference. The camera is lighter and so your own movements will be more nimble too, which fits the insect world better! I don't have an iphone, sadly.
It’s true — I’m much more nimble with the iPhone. Honestly, finding my first olloclip was a revelation. It kind of changed my life. 💜
