Hi,
I am the opposite side. I have a M2Zoom and use the Zoom feature on just about every flight.
I think it all depends on the type of pictures or video you are trying to make. The zoom is outstanding for the 48mp super-res still photos. And for video, again depending on the type of footage you are after, the zoom ability to change focal length and the corresponding parrallex of the subject vs. the background is outstanding and I think impossible to mimic with the fixed lens.
Yes, the
M2P has a better image sensor so overall provides higher quality imagery out of the camera. Are you just doing youtube videos? if so, what resolution. that might be something to take into consideration.
Are you looking for a device to be able to inspect objects? Or take images of wildlife? then the zoom would be the hands down winner.
For me, I am not a professional photographer doing commercial projects. I am a hobbyist and I enjoy publishing landscape/cityscape videos as well as offroad racing videos. I debated the same question back and forth. I chose the zoom and couldn't be happier with my choice. The reach of the zoom is pretty substantial, especially if you are doing 1080p format which gives you up to 4x zoom. I can really get in from a distance.
Here is a video where a buddy asked me to check out his house. I put it together as a gimmic video, but at around the 1min mark you can see how far the zoom can get in. This is from an altitude of about 300ft. There is the added 'magnifier' that was done post processing but the overhead wide view than zooming down into the driveway area is 100% the zoom function, nothing done in the video afterwards. Hope this helps.
