Yeah, I don't think that works like that. The zoom factor of the Mavic 3 tele lens is 7 (7.4 relative to the camera on the Air 2S). If you take a full image using the Mavic 3 normal camera, the image is 5280×3956. If you cropped that image to match the 7X tele factor, you'd end up with an image 713 x 534. I haven't shot an image with that low resolution, I think, ever, since my first digital camera (in 2002) was 2048 x 1536.The zoom lens on that was a deal breaker for me considering it's 3x the cost of the air 2s.
The sensor the 7x zoom uses is no better than the sensor on the mini 2. Depending on what you're shooting you're likely to get a better image cropped from either the Mavic 3s much larger micro 4/3 sensor or the air 2s 1" sensor.
Same thing with an Air 2S, original image is 5472×3648, 7X crop would be 739 x 493.
I think the tele lens and 1/2" sensor is a very significant advantage, thanks! You get a 15 degree FOV with a
4000×3000 raw image. I'll have some of that please.
