it was my understanding they screwed up with the focus cause all that changed later in 3+ life as in now...... my hate is the super modes are ridiculous for aerial, no good, looks weird. it has more settings in the raw mode than a 3, and they did something to the mpbs setting to make it more compatible with micro sd's that makes the file less quality....
I only see the quality difference when i crop 2.7 video down, it winds up a lesser product than doing the same thing to a 3. and, every mode i shoot in doesn't let me utilize the low light feature the 3+ has but mileage may vary depending what it's being used for.
