This is great news. I did some projects as surveyer and overall results and images are not best for photogrammetry due to wide lens in CGO3+.
I have 2 questions:
1. Will this new lens have any affect on image sharpness since it is double zoom and normally images are taken during movement of drone through prepared path?
2. What will be image resolution, now it is 4000x3000 px, you are writing 16MP, images on your examples are 7000-9000px?
This 8.25mm lens is far sharper than the stock original lens. I believe what you're asking about is pixel blur, which relates to making sure your shutter speed is fast enough so that the pixels are sharp and not blurred. For photos this is not typically an issue since the shutter speeds are much higher than video. Just watch your shutter speeds and adjust as needed if you are noticing any pixel blur.
Same pixel resolution (4000x3000) as the sensor is not changing. The reason some of the images shared above are higher resolution is that they are stitched from multiple photos, forming a panorama image.
