>>2912875>>2912903The physical size of the sensor is what really matters.
Not the megapixels.
Your DSLR has a respectable APS-C size sensor.
Your phone has a pathetic little 2/3" sensor at the most (probably smaller).
Do you think your 12MP pictures are too small?
Do you need more detail?
Then maybe upgrade.
If not, then don't. (or buy a better lens instead)
